Perform all Architect-Engineer (A/E) Services by licensed Architects and Engineers registered in the State of Wyoming.

Use the Schematic Design Drawings and the Scope of Work as the basis of the design (see attachments).

Select equipment, perform construction, TAB and Commission the system, and develop as-constructed drawings (from existing AutoCAD drawings) of the new equipment.

1.2 Location

This project is located at 1300 North 3rd Street, Rawlins, WY 82301-2407.

1.3 Background

The Rawlins Field Office is an approximately 32,000 square foot, two-story building, constructed in 2005. The existing rooftop air conditioning units, boilers, pumps, exhaust fans, VAV reheat coils, and VMAs contain components that have either failed or have reached the end of their useful service lives. Current energy use at this facility is also higher than desired.

The existing HVAC system consists of two indirect-direct (two-stage) evaporatively cooled rooftop air conditioners, with variable air volume airside (single-inlet VAV terminals), hot water reheat coils, and perimeter hot water cabinet heaters. There are also unit heaters and cabinet unit heaters for space heating. The rooftop air conditioners also contain hot water heating coils for tempering supply air. Exhaust fans have been provided for the toilet rooms, break room, telecom rooms, janitor rooms, the lab, and the electrical room. Two existing boilers provide hot water to the VAVs, unit heaters, and cabinet heaters.

The existing HVAC system controls consist of a Johnson Controls “Metasys” direct digital control (DDC) system.

The existing roof is a single-ply Thermoplastic Polyolefin (TPO) material.

Systems furniture is installed throughout the first and second floors.

The HVAC equipment replacement, controls updates, and additional associated improvements, include:

1.3.1 Demolition / Removal of the following Existing Items:

1. Two (2) existing rooftop air handler units.

2. Roof substrate, as necessary, to accommodate new rooftop air handler units.

3. Two (2) existing VFDs, serving the rooftop air handler units.

4. Thirty-two (32) existing VAV boxes with reheat coils and VMAs.

5. Thirty-two (32) existing thermostats.

6. Two (2) existing boilers; Two (2) existing boiler pumps; AND Two (2) existing hot water pumps.

7. Three (3) split HVAC units (indoor and outdoor units) serving the three telecom and computer rooms.
