Site work for a mixed-use development in Minneapolis, Minnesota. Completed plans call for site work for a educational facility.

Lump Sum Design-Build Services for a new district chilled water connection to the Thompson Center, located on the east bank of the Twin Cities campus. Refer to the Request for Proposal documents (found in the Attachments tab) for full project details/requirements. Question Deadline 01/16/2024 at 12:00 PM CT Respondent shall complete and submit the Targeted Business & Community Economic Development Questionnaire. The University is requesting Design-Build Lump Sum services to design and construct a new district chilled water connection to the Thompson Center located at 501 23rd Ave SE, Minneapolis, MN 55455. The existing roof mounted chillers at the Thompson Center have exceeded their max life and are beginning to fail. In lieu of direct replacement, Facilities Management (FM) and Energy Management (EM) have joined efforts to approve connecting the building to the central district chilled water system. The selected Respondent will be responsible for developing drawings which detail the routing of the new chilled water lines (start to finish). Drawings are to be developed in consultation with the University Engineers and formally submitted for University review along with a preliminary review with the Building Code Division (BCD). Upon approval, the Respondent (as the Engineer of Record) will develop a final set of drawings that can be permitted. This Project scope of services includes but not limited to: Project Design Guidelines - See the attached Owner Project Requirements (OPR) document developed by Energy Management for further definition of the Project guidelines / requirements. Civil Coordination - Investigation and routing of new HDPE chilled water supply and return lines which will tie-in at the intersection of 23rd Avenue SE and 6th Street SE. Scope includes validation of the chilled water line sizes and restoration of the disturbed existing conditions. Building Coordination - Coordinate the routing of the new chilled water lines through the building which may include select architectural, mechanical and electrical impacts (demolition, construction, restoration). The total construction budget for this Project is $330,000 (current dollars, no escalation). The main scope of work includes a connection between Thompson Center for Environmental Management (henceforth known as Thompson Center or TCEM) and the existing chilled water distribution network. As this building contains hazardous materials, cooling and dehumidification processes are considered a priority. TCEM's existing building loads include four air-handlers (one of which is semi-retired, AHU4), three of which have cooling coils, and two larger fan-coil units. The air-handlers serve 43,965 square feet, 17 total fume hoods and general exhaust fans, 5 of which are decommissioned and at least 2 are large, walk-in style fume hoods for mixing and packaging miscellaneous chemicals. The FCUs serve a remodeled office totalling 2148 square feet. The building's maximum cooling load is currently limited by the two Trane air-cooled rooftop chillers totalling 190 nominal tons of cooling. The chillers were initially designed to provide a 40% ethylene glycol solution at 42F. The air handlers account for roughly 173 tons of that cooling, with 22.5 tons being retired with AHU4 as noted above. The FCUs account for an additional 5 tons of cooling between the two of them. The University chilled water district operates at 41F chilled water supply temperature with a 59F chilled water return temperature - minimum of an 18F dT. The pipe size of the buried line will need to be determined based on the new flow requirements of the coils (using district CHW) and a pressure drop requirement of less than 4 feet of H2O per 100' of piping. For loads connected to the district, pressure-independent modulating control valves are preferred with a coil velocity of >2.5 ft/s. This project's scope does not currently include the replacement of existing building coils, but should be included as an add/alt item on the RFP. The current coils are operating at a 42F entering water temperature with a 14F dT. The following atlas map is included as a guiding document for the general locations of other buried utility infrastructure. All buried infrastructure will need to have its location verified via potholing or other location-finding processes.
