About this file
This document is a Questions and Responses file related to a federal contract opportunity for the Design Build Disposal/Replacement of Electrical Generators at the Dalton Cache Land Port of Entry in Haines, Alaska and the Design Build Replacement of the Emergency Generator at the Fairbanks Federal Building in Fairbanks, Alaska.
The key details are:
- The contract opportunity solicitation number is 47PL0124R0032. It is being issued by the General Services Administration Public Buildings Service Region 10.
- The scope of work includes replacement of generators, day tanks, and automatic transfer switches at the two locations. It also includes providing referenced documents such as one-line diagrams and existing arc-flash studies.
- Clarification was provided on several technical details, including the extent of building electrical service replacement, use of specifications in drawings, verification of heat exchanger sizing, and use of temporary generators during construction.
- Responses indicate that existing fuel piping and components can be reused where applicable, and that a new automatic transfer switch is required for the Fairbanks Federal Building.

| 4 | 1 | 7/31/24 | Technical | Please provide the following referenced documents referenced in the Scope of Work and |
Functional Specifications:
| a. Fairbanks: Full One-Line Diagram, Existing Arc-Flash Study | 8/2/24 | Please see the attached ten (10) files. | D. Fell | ||||
| 4 | 2 | 7/31/24 | Technical | For both sites, the scope of work requires replacement of the Day Tank and ATS. Only the Haines project has issued SOW/Specs for the ATS and Day Tank. Will a similar SOW/Spec be issued for the Fairbanks ATS/Day Tank or can we use the spec from the Haines project as the spec for the items at Fairbanks? | 8/2/24 | Haines-Day Tank and ATS have been replaced per another contract. The SOW for this solicitation has been revised. |
| Fairbanks - SOW 2.2.9 describes the sizing of the day tank. ATS and Day tank specifics is expected as part of the design build. | D. Fell/R. Mayfield | |||||||
| 4 | 3 | 7/31/24 | Technical | Please clarify the extent of the Fairbanks building service which is described as having exceeded its service life. Should replacement of the building electrical service be included in the design and construction scope? | 8/2/24 | The building electrical service is not required to be replaced and should not be part of the project's design | D.Fell | |
| 4 | 4 | 7/31/24 | Technical | Will full book specs be required? Can specs be inserted in the drawings if the spec requirements are small enough to be included there? | 8/2/24 | Specification book is not required and may be identified in the drawings | D. Fell | |
| 4 | 5 | 7/31/24 | Technical | Fairbanks. Do we need to verify that the heat exchanger is sized correctly or assume that it is correct and operate as such? | 8/2/24 | Contractor to verify | D.Fell | |
| 4 | 6 | 7/31/24 | Technical | Haines: Is a temporary roll-up generator required for the duration of the project? | 8/2/24 | Yes, temporary generator will be needed when primary generators are off-line | R. Mayfield | |
| 4 | 7 | 7/31/24 | Technical | Fairbanks: Section 2.2.5 states to provide a load bank that has a load add/shed feature. Is this feature to include automatic operation with the EG while it is operating normally, or will this load bank add/shed feature only be used for generating testing? | 8/2/24 | This will be used for testing | D.Fell | |
| 4 | 8 | 7/31/24 | Technical | Do we need to isolate the EG pads when we add the concrete housekeeping pad? | 8/2/24 | Unknown which building and what exactly is being asked. | D.Fell | |
| 4 | 9 | 7/31/24 | Technical | Do they want us to provide the environmental control panel for the EG room and then tie that in with their BAS or would they rather use connect directly to their BAS? | 8/2/24 | Unknown which building and what exactly is being asked. | D.Fell | |
| 4 | 10 | 7/31/24 | Technical | The 50kW load bank may not be able to be located close to the wall. Is there more space at the site to move the load bank further from the wall? | 8/2/24 | Unknown which building and what exactly is being asked. | D.Fell | |
| 4 | 11 | 7/31/24 | Technical | Can we assume that we can re-use the exiting fuel piping, valves, filters between the day tank and the 1000 FST to the greatest extent possible? | 8/2/24 | Yes, utilize the exiting fuel piping, valves, and filers where applicable | D. Fell/R. Mayfield | |
| 4 | 12 | 7/31/24 | Technical | I think that the generators will be out of service for more than 5 days, as is assumed on page 3 of 4 in the ATS section of the SOW. The power from the utility should continue to power the facility during this time. Does the GSA want a temp generator there as back-up during the time the generators are being replaced? | 8/2/24 | Temp generators will be needed for both sites when backup generators are off-line | D. Fell/R. Mayfield | |
| 4 | 13 | 7/31/24 | Technical | The one-line doesn’t show the existing 400A ATS as being replaced. The ATS section of the SOW requests a new ATS. Which is correct? | 8/2/24 | Haines-ATS has been replaced. Fairbanks would need a new ATS it has not yet been replaced | R. Mayfield | |
| 4 | 14 | 7/31/24 | Technical | What do they mean by 125A seismic rating on ATS page 3 of 4 of the SOW? | 8/2/24 | 125A is the seismic requirements of 2018 IBC, CBC, ASCE 7-16 and OSHPD have been met. | R. Mayfield | |
| 4 | 15 | 7/31/24 | Technical | Drawing A1.02 states “Existing louvers (three)...” The pictures show 3 existing 90 degree hoods. | 8/2/24 | Please provide what picutes you are refering to |
