3 1. Existing Construction Conditions A. Executive Summary Tech Assignment 1 touched upon some important aspects of MACA. The project will be delivered through the least risk, traditional design-bid-build approach. Davis Construction is serving as the general contractor in this arrangement holding a GMP contract with Mercersburg Academy. Reviewing the project schedule shows that the will be constructed over a 19 month schedule. MACA has no sequencing issues or phased construction. A table containing the building systems was also developed. The Center for the Arts requires demolition and excavation support, and has steel framing, CIP concrete, masonry, a mechanical system, an electrical system, and a curtain wall system. The curtain wall system in MACA proves to be most interesting in the fact that it is a combination of exposed teak and mahogany, steel, and glass. The exposed wood presents some durability issues. MACA will cost $16.29 million (building costs only). This price increases to $21.76 million when the site work, permitting, and general conditions are added in. Both the D4 and R.S. Means estimates came in lower at $14.2 and $11.16 million (building costs only) respectively. The site plan for the was compiled with Mercersburg Academy in mind. The positions of items, such as the crane, have been located as far out of the line of sight as possible. MACA jobsite fencing near the mall area on the campus has fabric lining to further protect the scenic views at Mercersburg Academy. Local conditions at Mercersburg parallel the attributes. The building is located on spread footings, but careful attention must be paid for the presence of sink holes, which occur from porous limestone pockets below the sites surface. Mercersburg Academy is constructing the to replace an outdated Boone Hall (home of the theater and musical departments). They expect this building to be constructed in a timely manner at a reasonable cost to Mercersburg, while also consistently maintaining the scenic beauty of the campus. 1

4 B. Project Delivery System MACA follows a traditional delivery system of design-bid-build. The owners, Mercersburg Academy, addressed the following criteria when deciding upon a delivery system: financial, time, design, and quality. They looked for a system that provided the least risk to the project. The traditional approach has been the predominant delivery system for construction over the years. It brings a sense of security to any owner in that it presents the least uncertainty on how the project will progress, while also allowing contractual protection for the owner. This in turn represents the least level of risk. The following organizational structure outlines the hierarchy within the MACA project. It also shows the relationships between key project players, being a contract or just an informal relationship.

5 C. Project Schedule Summary A one page MS Project schedule for MACA can be found attached in the Appendix. The foundation sequence of the schedule basically consists of excavation, spread footings, and a partial retaining/foundation wall on three sides of the building. On the other hand, the structural activities in the schedule consist of a slab on grade, slabs on metal decking, and steel columns and beams. Lastly, wall/floor finishes, doors/casework/millwork, and fixtures and trim compile the finishing sequence. D. Building Systems Summary Yes No Work Scope If yes, address these questions / issues X Demolition Required? Involves complete demolition and removal of existing building and site components, salvage of some existing items, and preparation of existing areas to receive work. Demolition does not include any asbestos or hazardous material removal. X Structural Steel Frame MACA has a combination of diagonal bracing and lateral moment connections as its bracing system. Every floor, except the SOG, is composed of a 5.5 NWC 18-gauge composite slab on metal deck. A large mobile crane will place the steel from locations on both the East and West sides of the footprint. X Cast in Place Concrete The only CIP concrete on the job are the spread footings, floor slabs, and a two-story architecturally exposed concrete exterior foundation wall on the South, East and North sides of the building. Placement will be by truck. The formwork selection for these features is usually made by the subcontractor. Since MACA is not under construction yet, an assumption of plywood can be made for the formwork. 3

6 X Precast Concrete NA X Mechanical System The mechanical room is located on the Lower Level floor on the North side of the building. An all air, VAV system is employed in the. It distributes air through aluminum ductwork. MACA is protected by a standpipe sprinkler system at a temperature classification of 165 F. X Electrical System Incoming service at MACA is 5 KV with a 1500 KVA transformer. The main switchboard is a 277/480 V 3 phase 4 wire 3000 amp bus. A 230 KW emergency generator provides back-up power. X Masonry The only stone used on MACA is a two story high (Lower Level Mezzanine) Pennsylvania limestone and bluestone veneer located on the North, South and West elevations. This non-load bearing façade is connected to the building with ties. The stone will be completed one building face at a time with minimum scaffolding. X Curtain wall The window wall system on MACA is composed of teak & mahogany, steel, and glass units. The design responsibility is that of the architects. A Duratherm system wall is specified in the specs, so this curtain wall system lends itself well to a custom installation. X Support of Excavation The initial excavation strategy will involve an attempt to step back the walls at a safe slope in order to perform the excavation. If there is not enough room, another system will be explored. Either way, the system will not be permanent. There will be no need for a dewatering system. 4

7 E. Project Cost Evaluation Actual Building Construction Cost and Costs per square foot (*Not including land costs, site work, permitting, general conditions etc.): o $16.29 million o $245/s.f. Total Project Costs and Costs per square foot: o $21.76 million o $344.85/s.f. Major Building Systems Costs and Costs per square foot: o Structural System $1.76 million $26.56/s.f. o Mechanical System $2.82 million $42.41/s.f. o Electrical System $1.78 million $26.87/s.f. o Theater Performance Equipment $1.64 million $24.73/s.f. Design Contingency and % design contingency related to Construction Costs: o $779,410 o 4.8% Parametric estimate from D4Cost Estimating Software (please find a complete copy of the estimate attached in the Appendix): o Smart averaged three separate buildings: Herberger Theater Center 80,000 s.f. / 827 seat theater / 327 seat stage American Music Theater Lancaster, PA Fine & Performing Arts Center 84,000 s.f / 600 seat theater with orchestra lift o Overall Building Cost: $14.2 million $21.35/s.f. o Structural System $2.67 million $40.19/s.f. o Mechanical System $1.66 million $25.03/s.f. 5

8 o Electrical System $2.04 million $30.71/s.f. Square Foot Estimate from R.S. Means 2004 Square Foot Costs: o Closest building type to the is College, Classroom, 2-3 stories 4 story building 66,500 s.f. 650 l.f. perimeter o Overall Cost from Means (please find the complete cost data attached in Appendix): $11.16 million $167.87/s.f. A high school center for the arts turned out to be difficult to price as far as the estimates are concerned. The cost data was relatively unknown. There were some pretty distinct differences between both the D4 and R.S. Means estimates when compared with the actual building cost. The D4 estimate actually proved to be the closer of the two, with a difference of only $2 million less than the actual building cost. Accounting for this difference was the inconsistencies between the mechanical and electrical systems, along with the theater performance equipment. The other estimate from R.S. Means did not come as close, posting a difference of $5 million less than the actual building cost, doubling the D4 estimate. The primary driving force for this discrepancy is the fact that the closest match to the in Means was a 2-3 story college classroom. Most of this cost difference is caught up in the theater area, as the college classroom did not have a theater. 6

9 F. Site Plan of Existing Conditions The Site Plan of Existing Conditions is attached in the Appendix. G. Local Conditions Some local conditions exist which can influence a project. In South-central Pennsylvania where Mercersburg is located, there is no distinct preferred method of construction, although steel buildings are the typical structural system. Labor-wise, MACA is primarily a non-union job, matching the local labor force for the most part. Parking regulations also exist on the site because of the lack of parking space. Only the superintendent and foreman of subcontractors will be allowed parking directly on site. It will be the responsibility of each subs foreman to bus the remaining laborers onto the site from a parking lot one mile away. Recycling and tipping fee information is not available. In the Geo-technical Report, it was concluded that the proposed building may be supported on spread footings placed on natural soils, bedrock, or new compacted fill. Limestone bedrock, disintegrated limestone, natural lean clay and silt soils, or new compacted fill should be encountered at normal spread footing depths. Interestingly, subsurface conditions on the site are known to contain limestone pockets, which are a red flag indicator of possible sink holes. To ensure that these sink holes are not present underneath the footings, an air track probe will be conducted at each footing location. Finally, a permanent under-floor sub-drainage system, including sumps and pumps, will be necessary to maintain ground water levels below the lowest level. H. Client Information The owner of the is Mercersburg Academy, a private high school in South-central Pennsylvania. This facility is being constructed to replace the old, out-dated existing Boone Hall, which was home to the theater and musical departments at Mercersburg. Cost expectations for the project are fairly high, as the building is currently over budget. Mercersburg doesn t want an extremely high priced building, but they do expect a very high quality of finishes, which inherently drives up the price. Overall building quality and safety both carry high expectations with Mercersburg as they do with any owner. Mercersburg Academy keeps their campus facilities, buildings, and landscaping immaculate. Schedule-wise, there is an ample schedule length of 20 months, so there is no rush to fast track the project. Since there are no phased occupancy requirements with the building, sequencing will not be an issue; the building will be occupied upon final building completion. There are a few keys to completing the project to the owner s satisfaction. Mercersburg expects 7

10 a high quality, on time. They want the construction to occur safely and the jobsite to be as less of an eyesore to the scenic campus as possible. 8
