1 SOUTH DAKOTA BOARD OF REGENTS Committee on Budget and Finance AGENDA ITEM: III C DATE: June 19-20, 2013 ****************************************************************************** SUBJECT: SDSU Physical Education Complex Frost Arena HVAC Replacement Facility Design Plan South Dakota State University requests approval of the Physical Education Complex (PEC)/ Frost Arena Facility Design Plan to replace the HVAC system at an estimated cost of $2,100,000. The Board approved the Preliminary Facility Statement for this project at its December 2012 meeting. The Facility Program Plan was approved at the April 2013 Board meeting. The Building Committee approved the Facility Design Plan at the June 3, 2013 meeting. This project is primarily a maintenance replacement of the heating and ventilating equipment located in the Frost Arena portion of the Physical Education Complex. The original air handling systems in Frost Arena are original dating back to 1973 and these 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 remaining units need to be replaced to prevent any additional failures. Since this project involves considerable logistical challenges in replacing existing equipment, the anticipated replacement costs are higher than expected. The following design developments have changed from the Facility Program Plan: 1) the heat recovery units proposed have been removed from the project scope since the estimated return on investment for installing these units would be well over a hundred years; 2) fabric duct will be used in lieu of metal ductwork as the roof structural capacity will not allow for the metal type; 3) the existing air handling units will be left in place, disconnected and capped with the four new intake units being installed adjacent to the old units. Additional details of this proposed project can be found in the attached SDSU Facility Design Plan document and schematic drawings. (Continued) ****************************************************************************** RECOMMENDED ACTION OF THE EXECUTIVE DIRECTOR Approve SDSU s Facility Program Plan to replace the HVAC system in the Physical Education Complex / Frost Arena at an estimated cost of $2,100,000. SDSU has set aside $1,397,974 from FY13 and FY14 allocated HEFF funds, plus $575,000 in residual FY12 and FY13 HEFF project funds. Additionally, SDSU will reallocate the FY14 HEFF Ag Museum window replacement project of $130,000 to the Frost Arena HVAC costs.

2 SDSU Physical Education Complex Frost Arena HVAC Replacement - Facility Design Plan June 19-20, 2013 Page 2 of 2 Current funding in the amount of $1,397,974 has been set aside from FY13 and FY14 allocated HEFF funds. SDSU also has $575,000 in residual HEFF FY12 and FY13 project funds that will be used toward this project. Additionally, the approved HEFF FY14 Ag Museum window replacement project of $130,000 will be reallocated to the Frost Arena HVAC. These funding items total $2,102,974 to adequately fund the PEC HVAC project.

3 ATTACHMENT I 3 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

This result is 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, E. CHANGES FROM COST ESTIMATES FOR OPERATIONAL OR M&R EXPENSES No Change from FPP
