Questions and Answers Round 1

Q1. Building 102 – The picture reflects a fuel tank only. No information on the generator set for this building.

A1. B102 is not included in the requirement. Picture referencing B102 will be removed from Solicitation

Q2. Building 164 – There are no clear visible markings from the picture on the name plate indicating the voltage of this unit. Please verify the voltage of this unit.

A2. See Technical Exhibit 3 in the PWS.

Q3. Building 409 – Engine Overhaul. This is written very oddly. Normal engine overhauls are quoted AFTER an inspection has been conducted. To do this properly, it should be torn down and all components measured and checked against OEM specifications for acceptable wear… Then a list of components for overhaul pulled together from there. Any items not meeting OEM spec’s could wind up being a major issue (like upper and lower liner bores out of round), etc. etc. In fact, if an item is too far out of spec, then the engine may not be salvageable. Another example: Injectors…. To inspect an injector, they need to be “Pop” tested. Since injectors are very expensive, it would be advisable to pop test them prior to attempting to rebuild or replace them. If they are good, there would be no reason to replace them and this won’t be known until after they are tested. It is very unusual to list “rebuild or replace worn fuel injectors” without knowing the condition of them first. Would it be possible to amend the spec to call out an initial inspection to determine the overhaul needed (like top end, major or minor, etc..), and then we could prepare a quote from that point?

A3. The PWS and corresponding CLIN structure have been revised to adopt a phased diagnose then overhaul approach. Contractors will conduct and price a comprehensive initial diagnostic inspection first. Based on the resulting Diagnostic Report, the Government will then authorize specific repairs by exercising the corresponding pre-priced CLINs for the overhaul work. See the revised PWS (5.2) and Price Schedule for the defined CLIN repair scopes.

Q4. Building 409 – Please indicate what you are seeing, what conditions exists, and why there is a call out for overhaul. What all has happened to this unit and what repairs have been done? Has this unit suffered any critical failures in the past that could cause issues with overhaul (like using oversized bearings, etc.).

A4. The Government does not have a historical maintenance record for this generator.

Because the conditions are unknown, the PWS has been updated (5.2) to require a comprehensive initial diagnostic inspection first. This inspection will determine the unit's actual wear against OEM specifications before any physical overhaul work is authorized.

Q5. During the site visit, the generator started and ran successfully under no-load conditions. Rather than pricing out an immediate engine overhaul (which requires a tear-down to determine if components meet OEM specifications), would the Government accept a 4-hour load bank test and fluid analysis first to establish a baseline and determine if an overhaul is even necessary?

A5. Yes, the Government concurs with this approach.

Please see the updated PWS Section 5.2. The requirement is now phased. Contractors will conduct and price a comprehensive initial diagnostic inspection first, including a baseline load-bank test and fluid analysis. Based on the resulting Diagnostic Report, the Government will then determine the necessary scope of work and authorize specific repairs by exercising the corresponding pre-priced CLINs for the overhaul work. See the revised PWS and Price Schedule for the defined CLIN repair scopes.
