About this file
This document is a Questions and Answers spreadsheet for a Generator Replacement project at Dobbins Air Reserve Base in Georgia. The project involves replacing generators at multiple facilities, including removing existing generators and installing new Cummins 150kW mobile generators with specific technical requirements such as EPA Tier 4 Final Certified emissions, 208-480V variable voltage, and integral 24-hour runtime fuel tanks. The contract (Solicitation FA670325B0006) will be awarded on a Lowest Responsive/Responsible Bid basis, with work to commence upon Notice to Proceed.
Key technical and operational details include: only one site on the flightline may be offline simultaneously, contractors must provide backup generators during changeovers, all surge protection devices must be from the same manufacturer, and O&M manuals must be submitted in both hard copy and electronic formats. Contractors will need to obtain airfield operation waivers, which typically take approximately two months, and must have qualified personnel for superintendent, safety, and quality control roles. The project requires a contract-specific QA/QC and Safety Plan, with badging and site access to be coordinated after award.

| 3 | Specifications - 828_2012_2125_2313.pdf | 1.3.2 | “150kW - Cummins C150D2RE Mobile Generator - Portable Generator Only”. | Can the mobile generator be used as the temporary generator during the construction period? | Yes – Generator must be maintained by the contractor during the duration of the project. If the generator is damaged, it must be repaired prior to turning over to the Government. It must be fully operational with no significant damage (like new condition). The government does expect hours of usage on the generator and the warranty will start at the time of start-up. Diesel will be provided by the government for all government owned generators; however, DEF if required will be the contractor’s responsibility to provide during construction for all generators used. The contractor must schedule diesel fueling with government as soon as possible prefer a week’s notice. | ||

| 5 | Specifications - 550_1001_2021_2300.pdf | 1.3.2 | “550 - Medical - Remove generator - Manual transfer with mobile generator”. | Is this an additional mobile generator that will stay at B550? | Building 550 will be set-up to take a quick disconnect connection for a mobile generator. The government already has a mobile generator that will be used there after the project is com-pleted. | |
| 6 | General Question | N/A | N/A | Besides the standard O&M manuals that come with the generator and transfer switches, will there be additional manuals required for submission at closeout? If so, can the Government provide a list of the required manuals? | The contractor will be required to provide all manuals available for the generator, ATS, 3-way switches and load bank connection. This would include the engine, ser-vice, overhaul, O&M, controllers, and parts manuals. How will the government know all the manuals required when we do not know the exact generators that would be ordered. See attached example of manuals required both hard bound and elec-tronic. | |
| 7 | General Question | N/A | N/A | N/A | Is it acceptable to provide the O&M's files only electronically or will hard copies need to be provided. | Both hard bound and electronic. |
| 8 | General Question | N/A | N/A | N/A | CLIN 0009 requests pricing for the Generator and Transfer Switch but drawing sheet E-104 does not show the installation of a new generator and automatic transfer switch. Please confirm that a new generator and automatic transfer switch is not to be installed. | A new generator or ATS will not be installed at building 550. This site will be set-up for a future mobile generator. |
| 9 | Drawings - 550_1001_2021_2300.pdf | Attachment 2 | N/A | "MTS switch sized is base upon generator size." | Drawing sheet E-104 General sheet note in top right corner states "MTS switch sized is base upon generator size". Please confirm size stated in sheet E-104 new work keynote #1 is correct. | Used detail 6/E-104 for size. The MTS must have cam-lock connections. That was the designer note for the size chosen. |

| 2.22 Surge Protection | "Total Protection | ||||||
| Solutions is one manufacturer who meets the UFC requirement." | Spec. Section 26 32 14.00 10 / 2.22 Surge Protection references Total Protection Solutions as one manufacturer that meets UFC requirements. It is our understanding that Total Protection Solutions is the only manufacturer that meets the UFC requirement because of the language that it provides unlimited free replacements of the unit if destroyed by lightning or other transient during the warranty period. Please confirm if this is correct. | All SPD’s must be by the same manufacturer. If another SPD company is found that meets all the UFC requirements we would approve. I have reviewed multiple differ-ent companies SPD’s, and I find that their warranties or their construction or specs do not meet all the requirements. | |||||
| 12 | General Question | N/A | N/A | N/A | Will night shift or weekend work be required to accommodate flight line activities? | Normally we work during duty hours. We cannot have more than one system down at the same time on the flightline. If more than one site is being worked on then one must not be on the flightline. Airfield systems work in pairs this why we cannot have more than one down. | |
