1 FACILITY DESIGN PLAN FOR HARDING HALL RENOVATION AND ADDITION SOUTH DAKOTA STATE UNIVERSITY DATE: March 29, 2017 SDSU requests approval of this Facility Design Plan for renovation and addition to Harding Hall. The revised Facility Program Plan was approved by the Board of Regents at the October 2016 meeting. A building committee was appointed and the design team of JLG Architects was selected on July 13, The Preliminary Facility Statement was approved by the Board of Regents at the April 2015 meeting. The State Legislature passed and the Governor signed Senate Bill 10 on February 19, The bill approved the renovation of Harding Hall for an estimated cost not to exceed $12,000, A. ARCHITECTURAL, MECHANICAL AND ELECTRICAL SCHEMATIC DESIGN The spaces are consistent with the program requirements and facility described in the Facility Program Plan. The following drawings are attached that illustrate the design: Architectural and Structural Schematic: Drawing Title Page No. First Floor Plan 7 Second & Third Floor Plans 8 Exterior Elevations 9 Architectural Renderings North Elevation & Interior Lobby 10 As stated in the Facility Program Plan, SDSU is planning to reuse and upgrade Harding Hall for academic use. The first floor of the building will be dedicated to two classrooms, study space, and building service space. The finishes and technology for the classrooms and study space in the lower level have been identified as an add alternate to the project, in order to accommodate budget flexibility and maintain a viable project. A small addition will be required to meet the code required circulation needs of the facility. The proposed addition includes the building elevator, lobby, study space and stairs to floors immediately adjacent to the grade level. The south addition that would have provided a link to Daktronics Hall has been removed from the project scope, due to budget limitations. Based on the space needs identified in the programming phase; Harding Hall will adequately accommodate the Economics Department. The Economics Department will fully occupy the second and third floors of the building. Additional space on the first floor has been allocated to University classroom space and student study space, but is insufficient for an additional academic department. The space function, use code and net square footages are enumerated in the following table. Pg. 1 of 10

The spatial configuration is designed to work around existing interior columns. Removal of interior columns would require extensive structural work and be cost prohibitive for the project. Cut openings through the existing concrete slab may be required for new HVAC ductwork. New openings; as well as, additional roof loads from equipment will require reinforcement of the concrete floor and roof slabs. This will likely be accomplished with carbon-fiber sheet reinforcing. The building addition will likely be steel framed with metal stud infill wall construction. The addition will likely be clad with a metal panel and curtain wall system. The general aesthetic goal is a combination of masonry, metal, and glass that will tie into the aesthetics of the recently completed Architecture, Mathematics, and Engineering Building. The foundation of the addition is to be standard spread footings located below frost depth. The need for over-excavation or deep foundation systems is not expected. Maintenance & Repair: A number of maintenance and repair projects will be a part of this major renovation. The projects include tuckpointing, HVAC replacement, plumbing replacement, asbestos abatement, roof replacement, accessibility alterations, window replacement, improved building envelope, energy efficiency upgrades, electrical upgrades, fire suppression, fire alarm replacement and entrance door replacement. Asbestos Abatement: All asbestos containing materials will be abated prior to general construction. A certified asbestos remediation Contractor will be hired to perform the work. Selective demolition has been performed to determine the extents of hazardous materials throughout the building. Mechanical Schematic: The design of the building HVAC system shall provide for the safe operation of the building as well as the health and comfort of the occupants. Code requirements and LEED V4 silver rating shall be the standard for the design of the HVAC systems of this facility. Pg. 2 of 10

3 The building is supplied with steam for heating from the Central Heating Plant and will be connected to the Central Chiller Plant with a new line that will extend from a connection located south of the Architecture, Mathematics, and Engineering Building. The new line will be sized to accommodate future connection to Daktronics Engineering Hall. The campus steam service will be reused in place. Heating The existing steam piping and pneumatic controls will be removed. The first floor mechanical room will contain steam to hot water heat exchangers, hot water circulation pumps, condensate pumps, and accessories. Multiple heat exchangers are being considered to allow greater flexibility and efficiency in the building heating system. The system will provide tempering of fresh air to the building, perimeter radiant heating, and terminal heating through a chilled beam system. The chilled beam system pumps heated or chilled water through a piping system that is integrated with the fresh air supply system. As the tempered and dehumidified outdoor air passes over the heated or cooled coils of the chilled beam it is conditioned further to meet the desires of the building occupant. Cooling Due to the restricted ceiling space available the mechanical cooling will be provided by a chilled beam system. This system allows for reduced duct sizes, since terminal heating and cooling is being provided by a water loop system. The primary purpose for air being supplied to the building is for indoor air quality. The air is dehumidified and tempered at the air handler and then conditioned to meet occupant comfort needs at the space by the chilled beam system. This system allows for maximum controllability, and efficiency. It also reduces the impact on ceiling height due to reduced duct sizes. Heat recovery will be used within the chiller equipment; as well as, between circuits serving the south and north zones of the building. The heat recovery will allow sharing of heat, while reducing the demand on the central steam and chilled water systems. Ventilation The building is not currently mechanically ventilated. The project will include a dedicated outdoor air system consisting of two (2) energy recovery ventilators with total energy wheels. One unit will be installed in the first floor mechanical room. This unit will serve the first floor and north entrance addition. The second unit will be installed on the roof and be dedicated to the second and third floors. Fresh air will be distributed vertically through multiple duct chases to reduce the size and quantity of horizontal duct runs through the chilled beam system. Controls The building automation systems shall be designed as a direct extension of the existing campus system. The system shall contain all points and programming as required to allow for automated control and monitoring of the new heating, cooling and ventilation system. Pg. 3 of 10

4 Plumbing Schematic: Water Service There is currently a 4 cast iron water service for the building. There is no fire protection service in the building at this time. A new 6 fire protection service will be provided from the 8 main near the northwest corner of the building. It is also the intent of this project to replace the existing domestic water connection due to the age of the cast iron piping. The new sanitary waste for the building will be connected to existing underfloor mains within the existing footprint of the building. Domestic Piping Copper piping will be used throughout the building per SDSU design standards. Waste Piping The existing roof drain will remain in place and not be modified. Rain leaders will be rerouted as needed due to site modifications. Above grade waste, vent and storm piping shall be cast iron drain piping with no-hub couplings. Piping below grade shall be PVC, per SDSU design standards. Existing cast iron vent piping that is no longer in use shall be removed. Plumbing Fixtures Plumbing fixtures will meet ADA requirements and be low flow sensor operated. Gas Service Gas service will only be required for miscellaneous loads. Primary heating and cooling will be provided by the Central Utility Plants. Electrical Schematic It is not anticipated that the existing electrical service serving the building will need to be replaced. All of the secondary electrical within the building will be replaced to accommodate changes to the floor plan and occupant needs. Site Lighting Site lighting will be a continuation of existing site lighting established for the engineering quadrangle. Power Distribution Switchboards: Existing 208 Volt switchboard will remain and serve mechanical equipment loads. New panelboards will be installed as required for plug loads and lighting throughout the building. Emergency Power An emergency generator is not required. Grounding All grounded buses from switchboards and panelboards will be connected at a central ground system in the electrical room. Pg. 4 of 10

5 Security System Rough-in for card readers at the main entrances shall be provided. Lighting Systems LED lighting fixtures will be utilized where possible. Counseling rooms may require less institutional style lighting. Motion detectors will be used to provide automatic on-off switching of lights in offices, storage rooms, bathrooms, and other selected rooms. The use of task-oriented lighting will also be examined. Daylighting will be used to supplement electrical lighting where appropriate. Exterior lighting will be controlled by a photocell. Emergency Egress Lighting Interior light will have a battery backup installed in the fixture for emergency egress lighting. Exit signs will be LED with battery backup. Data & Communications Hardwired data ports will be provided in all offices, conference rooms, and classrooms. Wireless system access points will also be provided on the first, second, and third floors. Fire Alarm System An addressable fire alarm system will be designed into the project and consist of an upgraded main fire alarm control panel, smoke and heat detectors in accordance with NFPA 101 & 72 standards. Energy Conservation There are a number of strategies being implemented to reduce energy consumption within the building. The energy conservation strategies include: variable frequency drives (VFDs), LED light fixtures, occupancy sensors, and optimizing daylight. 1.B. CHANGES FROM THE FACILITY PROGRAM PLAN Program and Scope Changes Due to budget limitations the link addition to Daktronics Hall has been removed. Move the existing e-commerce trading room from Berg Ag Hall to Harding Hall.
