About this file

This is a Questions and Answers document for the Retamal Dam Emergency Generator and Building design-build project issued by the United States Section of the International Boundary and Water Commission (USIBWC). The document addresses clarifications regarding project scope and technical specifications for the new generator enclosure and associated infrastructure.

Key project requirements clarified include: the new building will be a minimum of 150 square feet (final size to be determined during design), the generator will be diesel-powered, the existing building and generator will remain in place with no demolition required, and the HVAC unit (40-150 KW, 12,000-24,000 BTU/hr capacity) will serve only the generator enclosure, not office space. The new generator will connect to the existing electrical panel located in the existing building. Additional clarifications specify that the generator kW rating and Pennsylvania emissions tier will be determined by the designer as part of the design-build effort. Supporting documentation referenced includes a utilities map and conceptual sketch showing generator placement. The contractor is responsible for site preparation, system inspection, debris disposal, and quality control testing, with work restricted to USIBWC operating hours (7:00 am to 3:30 pm, Monday through Friday, excluding federal holidays). Warranty requirements per Section 01.78.36 include minimum 5-year coverage for the generator and automatic transfer switch, and 20-year coverage for roofing and roof systems.

1. What will be size of the New Building? This is design-build, will be determine by design, but we specified a minimum of 150 Square Feet.

2. What will be size of Generator being installed (Electrical/Gas)? Diesel

3. Can we get the Utilities Map? See attached file

4. Are we going to Demo existing Building and Generator? Existing building will remain in place

5. Can we get the rough conceptual sketch of the building and generator where it will be placed? See IMG below

6. What will be the size of HVAC unit and will that be only for generator or combined office space? Please clarify. Since this is a design/build, the size of the HVAC unit will be designed depending on the square footage of the building. Recommended size is 40-150 KW (12,000–24,000 BTU/hr (1 to 2 tons) of cooling, minimum, depending on heat rejection and ventilation design)). This area will not have an office space.

7. What are the scope and requirements for new building? The scope is to design/build a generator enclosure or building with a fuel tank.

8. Will the generator be connected to existing panel ? Or designer needs to access it ? New generator will connect to the existing panel located in the existing building.

9. Confirmed generator kW rating / size required for this project. Design-build will determine

10. Required EPA emissions tier or emissions standard. PA emissions tier will be determined by the designer as part of the design‑build effort.
