1 FACILITY DESIGN PLAN FOR PHYSICAL EDUCATION COMPLEX FROST ARENA HVAC REPLACEMENT SOUTH DAKOTA STATE UNIVERSITY May 17, 2013 SDSU requests approval of this Facility Design Plan to continue design and implement construction of the Physical Education Complex Frost Arena HVAC Replacement project. The Preliminary Facility Statement (PFS) was approved at the December 2012 Board of Regents meeting. The Facility Program Plan (FPP) was approved at the April 2013 Board of Regents regular meeting. Funding for the project was revised to $2,100,000 in the Facility Program Plan. 1.A. ARCHITECTURAL, MECHANICAL AND ELECTRICAL SCHEMATIC DESIGN The Physical Education Complex Frost Arena HVAC Replacement is consistent with the program requirements and facility described in the Facility Program Plan. The following drawings are attached that illustrate the design: MD101 Mechanical Mezzanine Level Floor Plan (Existing) MH301 Mechanical Building Sections (New Layout) EP101 Mechanical Catwalk Level Plan (New Layout) 1.B. CHANGES FROM THE FACILITY PROGRAM PLAN This project presents considerable logistical challenges with replacement of existing equipment which have resulted in higher than anticipated replacement costs. New equipment is difficult to introduce without affecting the use of the building. Continued design development has resulted in the following changes from the Facility Program Plan. Heat recovery units proposed in the Facility Program Plan have been removed from the scope of the project. Energy analysis by the A/E estimated a return on investment or payback for installation of heat recovery units to be over a hundred years. This result is Page 1 of 3

2 a function of the limited number of hours the arena is fully occupied requiring maximum ventilation. Fabric duct will be used for ductwork in lieu of tying into existing with additional new sheet metal duct. Structural capacity of the roof trusses does not allow for new sheet metal ductwork. Existing air handling units will be left in place. Existing roof mounted air intakes will be disconnected and capped. A bid alternate will be included in the bid package to have the existing air handling units removed. New air intakes will be installed adjacent to the four new air handling units. 1.C. IMPACT TO EXISTING BUILDING OR CAMPUS-WIDE HEATING/COOLING/ELECTRICAL SYSTEMS This is primarily a maintenance replacement project of the heating and ventilating equipment located in Frost Arena portion of the Physical Education Complex. The air handling systems in Frost Arena are original equipment dating back to The units have reached the end of their useful life. Of the ten air handlers serving the Arena, three have already failed and are beyond repair. The current air handling system needs to be replaced before additional failures occur that would prevent us from being able to serve the programmatic needs of the space. The project shall include numerous energy savings strategies including carbon dioxide control, building static pressure control, schedule programming and variable frequency drives on supply and return fans and pumps. 1.D. TOTAL CONSTRUCTION COST ESTIMATES The estimated total project cost is $2,100,000. Project Cost Estimate Construction Estimate $1,569, Facility Design and Project Administration $ 361, Total Construction and Design Cost $1,931, Project Contingency (11% of Construction) $ 169, TOTAL PROJECT COSTS $2,100, Page 2 of 3
