2 May 17, 2016 NMSU Williams Hall Renovation Schematic Design Civil Narrative The project consists of the demolition of the existing Williams Hall and Annex buildings, and the construction of a new facility in the existing parking lot that lies immediately to the west of the existing building. A new parking lot will be constructed on the former building site. Traffic and Circulation: The new building site will be an existing parking lot that has an existing vehicular access point on the south side of East University Avenue at the signalized intersection of University with South Solano Drive on the north side. This driveway would be closed, requiring modifications to the traffic signal and driveway. Options for access to the new parking lot to be constructed in the existing building location could come from 1) a new driveway connection to University across from Chaparral Street, 2) through the existing parking lot south of the Bookstore, or 3) a combination of both preceding options. A new Chaparral entrance would be located approximately half way between the signalized intersections at Solano and Jordan Road. It is unlikely that a new traffic signal would be allowed at this location due to the proximity to the existing signals. Coordination with the City will be required to determine the options and related requirements for a new access point to University and for closing the existing access at Solano. Grading and Drainage: The proposed building site is sloped from southeast to northwest, and surface runoff drains out to University via the Solano driveway. In conjunction with closure of this driveway, a drainage path should be maintained as either a surface conveyance, or by a new storm drain connection. A new storm drain line would likely be the preferred option because it could be extended to serve roof drainage from the new building, and also would allow controlled release if detention ponding were incorporated into the new site design. There is approximately 5 feet of vertical grade differential across the site from southeast to northwest. This grade change must be considered in conjunction with the design of the site and building. Wherever possible, the site design should make up the grade differential to minimize the need for stairs or ramps at entrances, and to avoid requiring any steps in the building floor. As shown by Dona Ana County Flood Insurance Rate Map (FIRM) Panel 632 of 1050 dated September 6, 1995, the site does not lie within a mapped FEMA floodplain, however, the downstream area to the west beginning at Espina Street is a mapped floodplain. Given historic drainage conditions with frequent flooding, it would be appropriate to incorporate measures to reduce the rate and volume of discharge from this site. This is consistent with NMSU Master Plan recommendations that drainage issues be addressed with new projects and that drainage infrastructure be designed with a goal of no net increase in runoff or a net decrease in runoff. The site design should incorporate low impact development (LID) techniques to retain first flush runoff from small rainfall events within landscaped areas for both water quality and quantity reduction purposes. These could be incorporated into parking islands and landscaped areas.

3 Site Utilities: As this is an infill project, the existing building currently has existing utility services that can and will be used to similarly serve the new building with modifications required in the areas where existing utilities lie within the proposed building footprint. The campus has a centralized steam and chilled water plant for heating and cooling. Steam and chilled water lines currently serving the existing Williams hall cross the proposed building site within the west parking lot and will require modification and relocation in conjunction with this project. Similarly, the University s potable water supply crosses the existing parking lot and will require relocation. The NMSU campus has a private sanitary sewer system that discharges to the City facilities. As with the aforementioned chilled water, steam, and potable water lines, the sanitary sewer serving the existing building crosses the proposed building site within the parking lot west of the existing building and will require a partial relocation as part of this project.

4 NMSU Art Center Schematic Design Phase Structural Narrative Date: The new art building will be approximately 58,000 SF in total area and will have an art gallery, office areas classrooms and work spaces. The east side portion of the building will have two stories and will contain working studios and classrooms, while the west portion will be one story and will contain offices and support areas, along with the Art Gallery. The two portions will be divided by a north-south walkway. Natural lighting from roof monitors and clerestory windows will be incorporated. Structural design will be governed by the requirements of the 2009 International Building Code (IBC). Design loads for the building will be based upon IBC and ASCE 7-05 requirements. The building will likely have a B occupancy with some Assembly areas within the building. The occupant load of the building is expected to be a bit over 800 occupants. This will put the occupancy category at III, per 2009 IBC Table Preliminary analysis indicates that the building s seismic design category will likely be C, which represents an intermediate seismic risk. Further determination of seismic design category will be dependent upon finalized occupancy classification and occupant load, along with site soils classification as determined by the project geotechnical engineer. Wind loading will be determined from ASCE 7-05 requirements using a 90 mile per hour 3 second wind gust as the design basis. The building foundations and floor slab support requirements will be based upon the recommendations of the project geotechnical report. The soil borings, laboratory analysis and written geotechnical report are all yet to be performed as of this time. Based upon our experience on previous projects at NMSU, we expect the project geotechnical engineer to recommend the use of shallow spread footings bearing on a several foot thick layer of overexcavated and recompacted engineered fill material. Floor slab support is also likely to include a recommendation for overexcavation and recompaction of engineered fill material. We believe it is likely that the geotechnical engineer will deem most on-site soils to be acceptable for reuse as engineered fill, so that extensive importing of engineered fill will not be needed if cut and fill amounts remain relatively balanced. The second floor structure will consist of composite steel framing using composite metal decking and a structural concrete topping slab. This system provides a durable and economical floor structure that can be readily designed to accommodate high floor load areas where needed, and is capable of spanning the 50+ foot clear span that is planned for the working studios. Open web steel joists supported on steel beam framing, with lightgauge ribbed steel roof decking will be used for the roof structure. Due to the required layout of rooms in the proposed floor plans, a

5 somewhat non-uniform bay spacing will be required in the north-south direction. Design floor loading will be determined after the occupancy usage requirements for the second floor spaces have been finalized. Lateral force resistance for the building will be provided by a combination of steel braced frames distributed throughout the building footprint along with steel moment frames. The braced frames will be placed at locations least likely to limit the flexibility for future floor plan modifications and renovations. At areas where steel braced frames are not desirable, the lateral resistance will be provided by moment frames. The moment frames will require larger beams and larger columns than the braced frames in order to achieve the necessary strength and stiffness, but will allow for greater openness of floor plans and greater flexibility for future floor plan reconfiguration. A partial basement may be incorporated into the project to accommodate mechanical and plumbing equipment. If so, the basement would be constructed with cast-in-place concrete walls along with a composite steel framed lid, similar to the framing system planned for the second floor Broadbent Parkway NE Suite D Albuquerque NM

8 MECHANICAL SYSTEMS Introduction This section describes the basis of the mechanical design for the new Williams Hall, Fine Arts Center at New Mexico State University. The mechanical systems will meet applicable codes and regulations, and current NMSU design requirements. The mechanical systems will be designed to minimize operational costs, and provide required access for maintenance, as well as to incorporate a measure of flexibility in the design. The project will be an approximately 57,000 sq. ft. new construction containing Admin Offices, Student Support, Graduate Studios, Art Gallery, Exhibits, Conservation Lab, Sculpture Studio, Metal/Jewelry Studio, Ceramics, Graphic & Printmaking, Drawing & painting, Photography, Computer Labs, and other support space. This section outlines the code requirements, design criteria and mechanical systems, which are currently under consideration for this project. It is the Owner s intention to obtain a LEED Silver certification for this project. The U. S. Green Building Council s LEED program will provide guidelines for the design, construction and operation of an environmentally sensitive, user friendly facility. Codes and Standards Applicable Codes and Design Standards 2012 International Building Code 2012 Uniform Mechanical Code 2012 Uniform Plumbing Code 2012 New Mexico Energy Code 2012 International Fire Code USGBC LEED New Construction Version 3.0 Rating System ASHRAE (American Society of Heating, Refrigerating & Air Conditioning Engineers) Handbooks NMSU Design Guidelines NFPA 90 A, 90B, and 101 American National Standards Institute (ANSI) Z 9.5, Laboratory Ventilation Standard Sheet Metal and Air Conditioning Contractors National Association (SMACNA) HVAC SYSTEM DESCRIPTION General The project is required to achieve a certification level of LEED Silver under the USGBC LEED 2009 NC Rating System. The criteria provides baseline systems to be applied to the facility, however it is felt an alternative system would provide enhanced energy efficiency, and better support the sustainable goals and requirements for the primary occupied areas of the facility. This alternative is intended only to be applied to the office and classrooms type areas of the building. The IT/Comm/Computer/Server Rooms will be served by dedicated Computer Room Air Conditioning Units or Single Zone Units as described in other sections of this response and required by the criteria. The area contained within the Art Gallery, Exhibits, and Conservation environment is separated from the remainder of the building with full height walls sealed to the structure to help hold the humidity control. A separate water chiller is needed due to the high campus chilled water temperature for de-humidification. De-humidification as well as adding humidity is needed to maintain the requested environment. B&P Project #7460 Page 1 May 2016

9 Site Considerations Steam and chilled water are provided from the campus service tunnel system. We assume the main lines in the campus tunnel are of sufficient size and capacity to serve the needs of the new facility. New steam, condensate, domestic water, fire protection water, chilled water supply and chilled water return lines will be extended to the building from the tunnel. Heating Hot Water Generation and Distribution Heating hot water will be generated in the mechanical room from two steam/hot water heat exchangers. Two heating water pumps provide circulated water to coils and air handling units. A condensate meter will be provided in the mechanical room. A duplex condensate return pumping system is also located in this room. Heating hot water (180 F) will be distributed to all coils, and shall use a 40 F temperature difference for the primary heating coils in the AHU s and a 20deg. F delta T for the terminal duct ( VAV) coils. Some heating coils are provided with two-way control valves, while a few others are provided with three way valves to maintain a minimum flow through the piping thus allowing a quick heating response when needed. The building pumps circulate water in the closed loop piping system, with each controlled from a Variable Speed Drive (VFD) that saves energy (electric and heating), by limiting the flow to only what is needed. Using a larger (40 Degree Delta T) both reduces the pumping energy and allows for smaller piping which reduces initial construction cost. Cooling System Plant Chilled water piping is connected to the NMSU campus chilled water system. Chilled water available is 42 deg F. Chilled water available campus pressure at connection point varies. Building chilled water pumps (Two pumps One lead/one stand-by) will be specified to boost pressure as needed to maintain building ΔP set-point. The pumps provide circulated water to coils and air handling units. Control and monitoring of the chilled water serving the building are via the facility management system (FMS). A chilled water meter will be provided in the mechanical room. All chilled water coils are provided with two-way control valves. The building pumps circulate water in the closed loop piping system, with each controlled from a Variable Speed Drive that saves energy by limiting the flow to only what is needed.

The unit will be a factory modular air handler consisting of casing with access doors, internally isolated fan, pre-filters, gas phase filter, final filter, steam preheat coil, chilled water cooling coil and glycol chilled water coil. The fan runs continuously. The DDC system maintains the temperature leaving the pre-heat coil and cooling coils to a constant leaving air temperature of 40.9 degrees F. The water temperature from the glycol water chiller delivered to the cooling coil is 36.0 degrees F. B&P Project #7460 Page 3 May 2016

11 Recirculating Air Handling Unit The unit is a factory modular unit to provide heating, cooling and ventilation for the Art Gallery, Conservation Lab, Art Storage and other similar area. The unit will be provided with Fans Array. Fans are plenum mounted on internally isolated structural steel frame. The fans are direct drive, controlled with a VFD to allow for filter loading. The fan is equipped with a flow measuring device so the operator can read cfm and make periodic adjustments to the fans output as filters load. Arrangement: Incoming air into the supply unit goes to the fan, pre-filter, followed by humidifier section for adding humidity, chilled water cooling coil, high efficiency particulate filters, gas phase filters, final flat filter, and discharge plenum. Filters and coils are sized at a maximum face velocity of 500 fpm. Coils: Cooling coils and heating coils have aluminum fins and copper tubing. Access doors shall be provided for coils, fan maintenance, filter removal, and any other components requiring service or removal. The air handler runs continuously with supply air temperature controlled from the new DDC system. The leaving air temperature can be as cold as 42 degrees F but will be adjusted upward by the DDC system whenever possible to save energy. The zone hot water re-heat coils provide final temperature control for each space served. Chilled Water Cooling System An air-cooled electric chiller coupled to two circulating pumps provides the primary cooling source for the humidity control air handling systems. The chilled water piping is cross connected to the NMSU campus chilled water system for backup. The NMSU system will be used whenever the chilled water is in the appropriate temperature and pressure range. Water is delivered by the chiller at a variable temperature down to 40 degrees F. Air Handling & Distribution Systems for Laboratory & Studios A makeup air handling unit will be provided to delivery cleaned, and conditioned outside air to the laboratories and Studios with an exhaust requirement. Unit includes energy recovery coils which exchange energy from the exhaust air stream (Laboratory Exhaust Systems) to the incoming 100% outside air stream in these Laboratory supply air handlers. Hot water pre-heat and chilled water coils follow the energy recovery coils. Water coils in air handling units are protected from freezing through the use of in-line circulating pumps for the heating coils. These pumps maintain flow through the coils whenever the temperature in the coil compartment drops to 40 degrees or less. The air handling unit will be packaged indoor with double wall factory constructed casings shipped to the site for final assembly. A multi-fan array is specified for energy efficiency and redundancy for this system. B&P Project #7460 Page 4 May 2016

12 Air handling units will be selected based on 115% of the required air delivery to allow for future flexibility and modifications. Air handling components shall be manufactured by locally represented companies. Air-handling unit includes MERV 7 pre-filters, and MERV 13, 85% final filters. Sound attenuators are recommended where necessary to reduce the sound levels transmitted to the building occupants from the fan systems. For AHUs with an airflow capacity of 15,000 cfm or greater, the smoke detectors will be mounted in the main supply air duct and main return air duct at the respective air-handling unit. The duct-mounted smoke detectors will shut down the air handling system upon smoke detection. For units less than 15,000 cfm, the supply duct-mounted smoke detectors will shut down the system. Laboratory/Studios Exhaust Air Systems Some areas of the building will now become intense labs or studios with exhaust air. Other areas will be teaching labs. All such areas termed Laboratories/Studios will have 100% outside air and exhaust air flow from the labs directly to the outdoors. The Laboratory Make Up systems are also single duct VAV design.. Room duct heating coils downstream of the supply air valves provide the required space conditioning. The Laboratory/Studios exhaust air distribution duct system will be designed with pressure independent variable air venturi valves. The Laboratory/Studios exhaust system will consist of a process fume hood exhaust and exhaust from the general lab space as required for maintaining negative pressurization within the laboratory spaces. At all times, a minimum Laboratory/Studios exhaust rate will be maintained at or greater than 2 AC/HR. Under occupied periods, a minimum exhaust air change rate of 6 AC/HR will be maintained. Occupied/Unoccupied exhaust rates for each laboratory will be controlled by either an occupancy switch in the space or from the EMCS based on a time of occupancy control schedule. Make up air will also be variable air volume and will track room temperature/pressurization needs. General laboratory exhaust is provided for situations where space cooling airflow exceeds the required exhaust rate. The only time the general exhaust will operate is when either minimum room air change rates are not being met, or when the cooling load is governing the room airflow. The design of the exhaust system will be coordinated with User to account for regular chemical exhaust fume hoods, walk in hoods and canopy hoods for heat extraction. The exhaust fans will operate in a Variable air volume mode, but will maintain a safe constant stack discharge velocity of 3000 fpm minimum. During low lab exhaust operational periods, outside deficit air will be introduced at the exhaust fans to help maintain required stack velocity. Each exhaust fan is sized for 50% of design exhaust requirements. This means that one fan can be cycled off during unoccupied building conditions as an energy conservation measure whenever building load permit. The fans are cross-connected on the suction side to allow a measure of operational redundancy. Should one fan be out of service, the remaining fan(s) can deliver 60% or greater air flow under most conditions. B&P Project #7460 Page 5 May 2016

13 Fume hood exhaust ductwork up to the control valve and to the trunk main duct is specified type 316 stainless steel with galvanized steel main ducts continuing to the terminal exhaust fans. The fume hood duct system has no fire dampers (or fire/smoke dampers) as required by NFPA #45 code requirements, as Fume hoods in the Labs must remain negative to the surrounding room to maintain the safe separations of occupants from hazardous materials that may be contained in the fume hoods. Laboratory/Studios VAV Exhaust Fans and Fume Hood controls are the most important component parts of the Safety Systems for the Laboratory Unit. To that end, it is recommended that these fans be the highest quality fans specifically designed for laboratory use. They are specified to be direct drive to minimize maintenance frequency, and eliminate belt drive components that can lead to failure and added vibration. These are to be Mixed Flow Induced Dilution Fans, with fan drive components having 150,000 hr. bearing life, and factory balanced assemblies not to exceed.5 mils, peak-to-peak. Air Handling & Distribution Systems for Admin Offices & Classrooms The Admin Office, Computer Labs, Classrooms and other supporting area will be conditioned with variable air volume (VAV) air handling unit. The air handling units will include, total energy recovery wheel, hot water preheat and chilled water coils. Zone level temperature control will be provided with VAV terminal units with hot water reheat coils. The air handling unit will be specified with double wall factory constructed casings shipped to the site for final assembly. Each unit is a factory modular component assembly and may be assembled in the field if too large for shipping assembled. Air handling units are selected based on 110% of the required air delivery to allow for future flexibility and modifications. Air handling units shall be manufactured by locally represented companies. Indoor air handling unit will be specified for economizer operation and energy efficiency. The variable air volume air-handling units contain the following components and features: Fan section with dual relief/exhaust fans with VFD s are specified to allow for better redundancy and pressurization control Filters MERV 7 & MERV % efficiency. Preheat coil ( FPM maximum face velocity, draw through arrangement) Air to Air energy recovery wheel with face & bypass dampers. Cooling coil ( FPM maximum face velocity, 6 row 12 fpi, 20 F water temperature rise, draw through arrangement) Fan section with dual supply fans with VFD s are specified to allow for better low load operation can use a single fan and at peak load operation both fans will be in operation. Each fan sized for 50% design load. Discharge plenum for sound attenuation Lights in all compartments for maintenance use. The air handling units design incorporate a built-in over-pressurization protection to allow fans B&P Project #7460 Page 6 May 2016

14 shut down in case of the system pressure built up to about 1.5 times over the system total static pressure. The air-handling units will be located in the mechanical fan room or a penthouse. Air handling unit fresh air intake and relief air systems consists of a wall louvers and field constructed double wall outside air and relief air plenums. Outside air and relief air paths are separated to minimize the re-entrainment of relief air into the intake air path. For AHUs with an airflow capacity of 15,000 cfm or greater, the smoke detectors will be mounted in the main supply air duct and main return air duct at the respective air-handling unit. The duct-mounted smoke detectors will shut down the air handling system upon smoke detection. For units less than 15,000 cfm, the supply duct-mounted smoke detectors will shut down the system. The air handling systems are single duct variable air volume with terminal reheat. The supply and return air quantity for the individual spaces will modulate between the maximum cooling cfm, minimum heating cfm, and the minimum air quantity required to maintain indoor air quality requirements. Supply and return air main ducts run from the unit to the individual floors through the fire rated duct shafts. Air distribution supply and the return air ducts on the floor are organized to allow for maintenance of plumbing, electrical, control and data devices. General Exhaust Air Systems Building exhaust is important to maintaining an adequate indoor air quality. There are several operational modes and exhaust flow paths. The HVAC units located on the fan room can exhaust up to 100 % of the outside air introduced in the building. The control system reacts to match exhaust air quantity to incoming outside air quantity, minus building pressurization air. This helps keep the building under a slight positive pressure to minimize infiltration, and keep the building clean. Restroom will have dedicated exhaust fans and will be kept negatively pressurized. Restroom will have dedicated exhaust fans and will be kept negatively pressurized. All toilet rooms and janitor closets and copy rooms will be exhausted at a minimum rate of 16 air changes per hour. Sawdust Collector System A dedicated exhaust and sawdust collector system will be provided for woodshop. Ventilation The outside air requirement will be provided based on ASHRAE The outdoor air intake at a system level will be calculated according to Table 6-3 System Ventilation Efficiency or Appendix A of ASHRAE Partial demand control ventilation will be used to insure Indoor Air Quality in the building. An airflow measuring damper will be installed in each air handler outside air intake to insure that the minimum required outside air is maintained. CO2 sensors will be installed in spaces with occupant density greater than 40 sq.ft./person. Indoor Air Quality Dampers and MERV 13 filters will also be installed at each air handler. B&P Project #7460 Page 7 May 2016

15 HVAC Equipment Noise and Vibration Control Air-handling unit primary silencers, and exhaust fan primary silencers will be duct mounted where required to meet room sound requirements Acoustical lining in ducts will be minimized to where needed to maintain sound levels within the occupied spaces as outlined in ASHRAE guidelines. The use of factory attenuators and externally insulated ducts is preferred over the extensive use of lined ducts due to difficulty of field quality control of lining. Internal vibration isolation will be provided for all air-handling units. External vibration isolation will be provided for centrifugal fans. Pumps in the Mechanical Room will be rigidly mounted either on housekeeping concrete pads or within the factory packaged skid assemblies and will be equipped with flexible connectors to minimize the noise transmission through the piping system. Laboratory exhaust fans will be equipped with discharge sound attenuators to help reduce noise that might otherwise create excessive noise on the campus. Deficit air inlet dampers associated with the laboratory exhaust fans also include acoustic inlet louvers to help attenuate noise that would otherwise exit this intake air path. IT and Electrical Room HVAC IT and electrical rooms will be served by a dedicated HVAC systems using campus chilled water or DX split systems. MDF Room The special MDF room is a critical space that is needed to remain in service throughout construction. This space includes a new self- contained cooling unit (split system) that will need to be put into service before demolition begins, and will need to be served from a separate power source. The building electrical equipment and systems will be replaced as part of this project. Refer to electrical sections of this document for the explanation of what is proposed to serve this MDF area. Automatic Temperature Controls Control systems for the building's mechanical components will utilize a computer-based energy management system. Chilled water systems, air handlers, steam to hot water conversion systems, pumping systems, and operating status of all components will be controlled through the facility management system (FMS). This includes remote monitoring and alarming of building equipment, temperature, and pressure relationships where needed. The building automation system will control all HVAC equipment to optimize performance and allow the operators to monitor and control the system through the operator workstation. The control system will be DDC type using a BACnet open protocol. The control system vendor will be specified as the manufacturer(s) preferred by the University in accordance with any other existing systems which may be located on the campus. The sequence of operations programmed into the system shall be in accordance with design intent documents. Factory packaged equipment will be specified with a BACnet protocol which B&P Project #7460 Page 8 May 2016

16 will communicated directly with the BAS network. All points available from the packaged controller will be available to the BAS. FIRE PROTECTION SYSTEM Interior Systems: The entire facility shall be protected by wet pipe fire sprinkler systems except as noted below. Each structure will be protected by dedicated fire sprinkler systems fed from the campus water system located in the utility tunnel. Fire sprinklers will be designed throughout utilizing upright heads for exposed areas and pendant heads for areas with finished ceilings. The systems will be configured to protect no more than 52,000 ft² per zone with individual zones protecting each floor level. Each zone shall include a floor control assembly comprised of a supervised grooved butterfly valve, a flow switch, and an inspector s test valve. This arrangement will allow for renovation or repair of portions of the system without compromising the status of adjacent levels. The inspector s test valves will be collocated behind a common access panel at the first floor of each wing. Similarly, the bottom of the elevator pit will be protected with a sprinkler head. The branch line feeding this head shall include a supervised grooved butterfly valve, a flow switch, and an inspector s test valve. The covered portion of the exterior yard will be protected with dry sidewall sprinkler heads. At a minimum a double interlocked preaction sprinkler system will be designed to protect the sensitive art storage, display, and conservation spaces. Should the requirements for these spaces grow to require a non-acqueous, gaseous clean agent system, the water-based system will be replaced with the appropriate system. This detail will be resolved early in the design phase. System piping materials will follow traditional selections to include black steel schedule 40 for mains, schedule 10 steel for branches, flexible sprinkler head connections, etc. Backflow prevention will be accomplished using an exterior reduced pressure type device located within a heated enclosure located near the southeast corner of the exterior yard. The fire department Siamese inlet connection will be located on the wall of the enclosure within 100 Ft. of a fire hydrant. Submittals by the fire protection contractor shall be reviewed by the engineer, architect and state code officials for design compliance and head layout. The system shall be hydraulically calculated with detailed design provided by the sprinkler subcontractor. The fire protection system will be designed in accordance with underwriter laboratories (UL), the jurisdictional authority, the owner s insurance carrier requirements (if available) and NFPA requirements. All valves, connections, appurtenances, etc. shall all be provided in accordance with appropriate UL and FM standards. All couplings and fittings used in the installation shall be in accordance with UL standards. No provisions for future expansion will be made within the design of the systems. The sprinkler system will be designed to allow ready conversion of non-instructional spaces into instructional spaces. No post indicator valves will be used within the system. All interior and exterior valves (i.e. backflow preventer OS&Y s) will be monitored through the FACP. B&P Project #7460 Page 9 May 2016

17 The following design densities will be used: Light Hazard Areas 0.10 gpm per square foot density over the hydraulically most remote 1,500 square feet, with a maximum sprinkler space of 225 sq. ft. in the following locations: Offices Areas Restrooms Help Desk Breakrooms Meeting Rooms Hallways Vestibules Ordinary Hazard Group I Areas 0.15 gpm per square foot over the hydraulically most remote 1,500 sq. ft., with a maximum sprinkler spacing of 130 sq. ft. in the following locations: Mechanical Rooms Transformer and Switchgear Room Electric Closets Computer Labs IDF Rooms MDF Rooms Server Rooms Elevator Rooms Ordinary Hazard Group II Areas 0.20 gpm per square foot over the hydraulically most remote 1,500 sq. ft., with a maximum sprinkler spacing of 130 sq. ft. in the following areas: Housekeeping Supply Trash Rooms Records Storage Building Management Storage Other Storage Areas in Excess of 100 sq. ft. containing combustible storage Paint booths PLUMBING SYSTEMS Storm Drainage System: New storm water collection systems will be provided for roof areas. The system will utilize a series of primary roof drains and secondary overflow drains that will be piped independently to a point 5-0 from the exterior wall or to a discharge at grade as is appropriate. The systems will be fully coordinated with the Civil Engineer. The systems will be designed to accommodate a rainfall rate of 2-inches per hour. The centerline trench at the exterior yard will be equipped with a sediment and oil interceptor and the outfall will tie into the on-site storm water drainage Sanitary Drainage System: All plumbing fixtures will be connected to a new conventional gravity-type sanitary sewer and vent system and will connect to the on-site systems. Pumps will be utilized as needed in the elevator pit. No-hub cast iron pipe will be used inside the building and PVC only allowed outside B&P Project #7460 Page 10 May 2016

18 the building. The exterior sanitary drain system will be designed by the Civil Engineer to connect with the main campus sewer system. All interior system connections will be trapped and vented with vents routed to termination above the roof level. The number of VTR s will be minimized to reduce potential leak paths. VTR s will terminate as far from fresh air intakes, combustion air louvers, etc. as is practicable. Provisions for cleaning out the piping system (FCO s, WCO s, COTG s) will be made at strategic points and as required by Code. The elevator pit will be designed with an oil-sensing sump pump that will discharge indirectly into a floor sink which will, in turn, flow through an oil interceptor. Floor drains will be included in all restrooms. The need for floor drains at emergency showers will be assessed during the design phase. Floor sinks will be incorporated into the mechanical room to serve various source needs. To the level deemed appropriate by the University provisions will be made to allow for future redevelopment of dry instructional spaces and graduate studies areas into wet instructional spaces. In keeping with the University s policy whereby all waste acids and bases are discharged into local collection tanks for off-site disposal, no acid-resistant waste piping will be installed under this project. The nature of the waste stream originating in the photographic processing and part washing areas will be assessed during the design phase to determine appropriate treatment needs. It is anticipated that there will be no areas with an H-occupancy classification. Where precious metals are used in jewelry fabrication, sediment collection traps will be used at all sinks to allow recovery of these materials. Where the drainage system is exposed to sediment, an appropriate interceptor will be designed to capture this material. Oil interceptors will capture contaminants found in painting studios and similar areas. In areas requiring humidification, duct drains will be used to control residual water that collects in the ductwork. Self-Sustaining Concepts: LEED certification to either a silver or gold level is a project goal and the fixture and trim selections will be made to support this pursuit for this project, dual flushing 1.1/1.6 water closets will be utilized. It is assumed that, in the course of one work day, a male will use a water closet once for solid waste and twice as a urinal. A low flow one pint/flush urinal will be used twice a day by males. In the same manner, it is assumed that a female will use the water closet three times in the day; one for solid and two for liquid. A 0.35/0.5 GPM lavatory faucet will be used after using a water closet or urinal. It is also assumed that genders are divided equally. All nonemergency showers will be equipped with GPM shower heads. A portion of the occupancy is assumed to use the kitchen sink once a day for 15 seconds. Janitor sinks are assumed to operate for 15 seconds intervals a day. Make-up water to mechanical processes is considered process water and therefore not applied to the LEED calculations. Plumbing Fixtures: All plumbing fixtures will be specified using commercial quality materials and trim and will be fully compliant with all applicable accessibility requirements and conservation standards. Water closets, urinals, and lavatories will be wall hung to ease housekeeping tasks in all public restrooms. Urinals will be provided with screens. Lavatories will be counter mounted and/or wall hung style fixtures as determined by the Architect. To address concerns over durability the showers will be built-up with tile and grout and detailed by the Architect. Service sinks will be B&P Project #7460 Page 11 May 2016

19 specified to be floor mounted. Stainless steel countertop sinks with kitchen faucets will be provided in break rooms as directed by the Architect. As appropriate sinks subjected to chemical wastes (photo processing, etc.) will be constructed of resin. Certain utility sinks within the studios and labs will be heavy-duty free-standing, stainless steel to support the needs of the space. Fume hoods and larger utility sinks will be located throughout the facility by the Architect. Exterior freeze-proof wall hydrants will be added in convenient locations to address wash-down requirements. The water supply to the hydrants will be independently valved to ensure effective winterization. Hose bibs will be added to all large restrooms to facilitate housekeeping activities. The emergency eye washes units, drench hoses, and showers will be located in hazardous areas as directed by the Architect. Potable Water Systems: The domestic cold water (DCW) system will connect to an existing main at a point that will support the anticipated load and will be extended to the new structure via direct-buried piping. A three valve arrangement will be added to the DCW tie-in point. A building backflow preventer will be installed in a heated enclosure and will preserve the potability of the Campus system. Additional backflow preventers will be used where internal processes pose a risk to the building s supply system. The new recirculating domestic hot water systems will be generated by a steam-to-water heat exchanger located within a mechanical room. DCW, 120 degree F. hot, and hot water recirculation mains will be routed through the facility. It is not anticipated that an industrial hot water system will be required in this project. Valves will be installed at each branch connection to provide isolation for maintenance. Riser valves will be provided to offer greater isolation for maintenance or system modification. To the level deemed appropriate by the University provisions will be made to allow for future redevelopment of dry graduate studies areas and instructional spaces into wet instructional spaces. Tepid water will be provided to all emergency fixtures via a local thermostatic mixing valve. Multiple water sources will be made available to the sculpture/multipurpose yard. The irrigation system will be addressed by the Landscape Architect. Non-Potable Water: New domestic cold water will be piped through a new reduced pressure backflow preventer to isolate the potable supply from the new non-potable water systems. As needed, make-up water will be interconnected with the hydronic systems. The utility requirements for the photo processing areas will be determined during the design phase and appropriate measures to prevent cross contamination will be incorporated into the design. Site Utilities: Domestic water, fire protection water, storm sewer and sanitary sewer will be designed to 5' outside the building and/or exterior yard. All pressure utilities will originate at mains within the tunnel system west of the building. Appurtenances (PIVs, backflow preventers, heated enclosures, etc.) will be incorporated into the Civil drawings. A connection will be made to the main in University Blvd. and a new yard line will extend to a meter and regulator assembly in the NE quadrant of the site. A medium- or low pressure system B&P Project #7460 Page 12 May 2016

20 will extend to the building to serve all gas-fired equipment. The operating pressure of the interior system will be selected to minimize installation costs. Pressure regulators will be used to reduce pressures to clusters of appliances (kilns, heaters, etc.) and the regulators will be vented to the exterior. A submeter will transmit data into the FMS system. Process Water: A water treatment system will generate water of sufficient quality to meet the needs of the humidification system. The water quality needs of the photographic processing equipment will be met similarly. A reduced pressure backflow preventer will protect the potable water system from possible contamination from the process. Process Gases: Centralized air (CA) systems and vacuum (VAC) systems will be incorporated into the plumbing systems design. The piping networks will deliver CA and VAC to each instructional space. To the level deemed appropriate by the University provisions will be made to allow for future redevelopment of dry instructional spaces into wet instructional spaces. The piping systems will feature valved branch lines and riser valves. The VAC system will be sloped to low-point drain valves to allow discharge of water should the need arise. To the degree needed the piping networks can be configured to serve the sculpture/multipurpose yard. The CA system will be based upon a duplexed, oil-free compressor combined with a storage tank, a duplexed air drying system, and duplexed particulate air filtration modules. The equipment skid/mounting frame as well as the control package will be configured to allow for future expansion should the facility see redevelopment of non-instructional spaces into instructional spaces. Pressure reducing valve assemblies will ensure adequate air pressure is delivered to all portions of the facility. It is anticipated that there is no need for a breathing air system to serve the paint booths. The VAC system will be based upon a duplexed vacuum pumps and an integrated storage tank. The equipment skid/mounting frame as well as the control package will be configured to allow for future expansion should the facility see redevelopment of non-instructional spaces into instructional spaces. The cost effectiveness of a centralized oxy-acetylene manifold and piping system will be evaluated during the design phase, reviewed with the University, and incorporated into the design if warranted. Plumbing Fixtures: The plumbing fixtures within each instructional space, including emergency equipment will be specified within this project under division 22. As appropriate, all fixtures will be specified to meet the necessary water/energy conservation goals and accessibility guidelines. Demolition: Upon completion of the Williams Hall building, the existing structure will be razed and all utilities will be removed back to the active main and capped.

NMSU will provide and install all medium voltage equipment which includes, but not is limited to, (2) new solid dielectric, 4 way, 25 kv primary Switches, (1) new service transformer for Williams Hall and all associated 25 kv feeders, plus (2) spare 4 raceway path/conduit stub outs, one for Kent Hall and the other one for Business Complex. NMSU will install, terminate and test all medium voltage equipment. The new 25 kv System scheme of work will be as follows: a) A new 25 kv primary Switch will be located where the existing primary vault is (North of Kent Hall), Switch S and S will be reconnected to this new switch. b) New 25 kv feeders will be provided between all new primary switches and into the new 480Y/277V transformer located near the South-East corner of the new Art Building. Transformer size will be determined by NMSU. Contractor, with NMSU approval, will connect the new Williams Hall electrical secondary power distribution to the secondary of this transformer. c) A new 25 kv primary Switch, which will be strategically located South East from Kent Hall. This switch will be provided for an easy point of connection to upgrade Kent Hall and Business Building to the 25 kv System in the future. d) Spare 4 conduit will be routed for Kent Hall and Business Complex. C. Temporary power to Existing Williams Hall and Annex 1. Existing Williams Hall and Annex Building should remain functional in place throughout the construction of the new Williams Hall building. Therefore temporary power will be provided in the following manner: a. Provide power connections from the new 25kV distribution that will serve the new building a temporary transformer that will serve the two existing buildings. NMSU approved the use of a temporary transformer for this purpose through the duration the construction of the new building. NMSU has in stock and will provide a 25 kv to 208Y/120V temporary transformer of adequate size (kva) for the existing Williams Hall and Annex. All of this, in the spirit of avoiding the probability of hitting the 5 kv line that runs underground to the existing Williams Hall with the new building footing. Secondary Power Distribution: 480Y/277V system 480Y/277V, 3 phase from NMSU pad-mounted transformer to the Main Switchboard. Location of the utility transformer will be coordinated with NMSU Electrical Engineering Department. Based on the preliminary load calculation, the proposed main service switchboard rating is currently expected to be 1600 amperes. The size of the main switchboard will be refined as loads are further defined. B&P Project #7460 Page 15 May 2016

23 480Y/277V, 3 phase electrical panels will be located in sub electrical rooms in the layout of each section of the building. 480Y/277V, 3Phase power will serve Lighting and Mechanical equipment in this facility. Plus any special lab equipment required at this voltage. 208Y/120V system. 208Y/120V, 3Phase power will be derived from step down transformers connected to 480Y/277V Electrical equipment. 208Y/120V, 3 phase electrical panels will be located in the same sub electrical rooms with the 480Y/277V equipment in each section of the building. 208Y/120V power will serve general power such as receptacle loads, computer loads, appliances, vending, and some mechanical/plumbing equipment as required. 208Y/120V power will serve Lab and Art Display equipment. Due to the prevalence of communications and computer loads within the building, the 208Y/120V distribution system will be derived by means of harmonic-mitigating dry-type transformer(s). Minimum rating will be K-4. Branch Circuits: Individual circuits will be used for general lighting and receptacle loads. NMEC device quantities will be adhered to on a branch circuit. Generally, loading on lighting circuits will be limited to 75% or less of the branch breaker rating. A minimum of 30% spare breakers / space will be allowed in all branch circuit panel boards. All single phase branch circuits will have dedicated neutrals for each phase conductor. An equipment grounding conductor will be run in each branch circuit. Uninterruptible Power Supply (UPS) There is currently no plan to provide a central UPS to serve communications and/or computing loads in the building. It is anticipated that the owner will provide small local UPS units for critical loads. Flexible Power in Labs or Art display locations: The building will be designed to provide flexibility for quick addition of new Art programs and/or displays. Panels will be located in each Art area. This will be to provide the greatest flexibility for connection of branch circuits and future loads. Life Safety (Emergency Power) Life Safety egress lighting (Emergency) loads will be provided with central battery inverters. They will be located in electrical rooms. NMSU campus continuous power will not be used per direction of NMSU. Fire alarm and communications systems will have self-contained, integral batteries to operate equipment for a set time in the event of a power outage. A generator for emergency power will not be allowed for this building per direction of NMSU. B&P Project #7460 Page 16 May 2016

24 Surge Suppression Surge Protective Devices (SPD) previously referred to as Transient Voltage Surge Suppression (TVSS) will be installed at the main switchboard and at the 208Y/120V load panels. The SPD is used to minimize damage from electrical transients that can affect or harm electronic equipment.

Grounding System The grounding electrode system will consist of driven electrodes, structural steel where capable of attaching to structure, and cold-water electrodes. All of these electrodes will be joined together at the building main grounding bar, adjacent to the main electrical service panel for each structure. All feeders and branch circuits will contain insulated, copper, equipment ground conductors. Lighting Exterior Lighting Exterior building egress areas will be illuminated with building mounted luminaires utilizing full cut-off optics so as to minimize light pollution, to contribute to the LEED certification, and to comply with the New Mexico Night Skies Protection Act. Lighting levels will be designed in accordance with IESNA recommendations. Except for the security lighting if, the control for the exterior lighting will generally be via an astronomic time-clock function as part of the building lighting control system. The security lighting will be photoelectric control-on at dusk and photoelectric control-off at dawn. Energy efficient LED luminaires will be a design standard for exterior lighting. Interior Lighting The focus is to provide appropriate levels of lighting for the spaces while minimizing energy use in order to contribute to a LEED Silver certification if required to. Most areas throughout the facility will utilize energy efficient LED Luminaires. Night/Security lighting is not anticipated to be used unless NMSU directs otherwise. IESNA recommended foot-candle levels will be used as the design standard. Some of the baseline lighting criteria for the various spaces are as follows: Offices: LED 2 X4 troffer type luminaires will be used for general illumination. Control will generally be via local manual switches, providing multi-level control. In those spaces with sufficient daylight, either dimming or separate manual switching of fixture rows adjacent to windows will be incorporated to take advantage of energy savings. Vacancy B&P Project #7460 Page 17 May 2016

25 type sensors will also be deployed to help with energy savings. Design Foot-candle Levels: 30fc to 50fc. Learning Studios: To achieve a level of flexibility and simplicity, dimmable LED lighting control will be considered for use in these areas. LED luminaires will be of high color rendering and recessed in lay-in ceilings. Control will generally be via local manual switches and dimmers.

Linear pendants will also be looked at where exposed ceilings are called for. Control in these areas will generally be via local manual switches, providing multi-level lighting schemes. In spaces with sufficient daylight, either dimming or separate manual switching will be incorporated to take advantage of energy savings. Vacancy type sensors will also be deployed to help with energy savings. Design Foot-candle Levels: 75fc. Entry/Lobby/Public Circulation Spaces: Lighting will need to be able to accommodate displays, circulation, and casual seating. Lighting in these spaces will reflect a level of higher finish and design. It is anticipated that a combination of LED down lights and LED suspended decorative luminaire types (depending on the configuration of the space) will be used to create a comfortable and dramatic environment. Depending on the amount of daylight incorporated in these spaces, these fixtures may be dimmed or switched in response to input from a photocell. Occupancy sensors may be considered to prevent the fixtures from being left on for an extended period of time. Switching will be via central control. Design Foot-candle Levels: Lobby: 20fc, Circulation: 15. Storage Spaces: LED 1 X4 strip type luminaires will be used.
