Question Response Page Section Paragraph

05/07/25

Spec section 01 35 26, paragraph

1.8.3 states the level 2 SSHO may not serve as QC manager or superintendent. However, spec section 01 45 00, paragraph 1.6.1.1 states the QC manager is also to serve as the SSHO. Is the government allowing those 2 roles to be performed by the same person?

Yes

05/07/25 Will the government also allow the superintendent to perform the roles of SSHO and QC manager?

No

05/07/25 How thick is the concrete slab over metal deck that contractors will be removing?

See detail C3 Sheet A- 501.

05/07/25

Is the expectation for the contractors to remove the concrete slab down to the metal deck, or just deep enough to remove the current hand rails and install new?

Remove existing slab, metal deck, adjacent structure, etc. as necessary in order to complete the work.

05/07/25

How far out from the hand rails are contractors to provide saw cutting to remove the concrete and hand rails?

It would help if there was an approximate quantity for removal of concrete for all contractors to base our bids on so everyone is bidding on the same amount.

The Government expects the contractor to remove existing slab, metal deck, adjacent structure, etc. as necessary in order to complete the work.Only repair/replace what is damaged or removed to facilities per the SOW.

05/07/25

SOW asks contractors to repair all cracks along topside of balcony decks to eliminate water infiltration.

Can the government provide an approximate amount of cracks to be repaired so all contractors are basing their bids on the same amount?

We believe the cracks are superficial and need to be addressed IAW concrete top coat manufactures recommendations.

05/07/25 Is there an approximate amount of stucco repair that is anticipated being required on this project?

No. Only repair/replace what is damaged or removed to facilities per the SOW.

05/07/25

SOW asks contractors to apply gray waterproof deck coating to both balconies. Are contractors to remove the waterproof coating completely from each balcony and replace, or just in areas where the waterproof coating is damaged? If it is the latter, will the government provide approximate square footages of the coating that needs to be repaired?

The Government expects the entire balcony to be coated IAW with manufacture's instructions.

05/15/25

It was mentioned during the site visit that the contractors are responsible for determining the best means to install the new railings into the deck.

If this is the case, would that make this project a design/build, as we would need an engineer to provide stamped drawings as well as performing calculations on if the structure can bear the required weight?

This is a design bid build project. A portion of the project is delegated design as shown on drawing A- 501 and specification 05 12 00 Paragraph 1.3.3

05/15/25

Are there any more current record drawings showing how the existing rails are installed? There appeared to be multiple areas of differing means of installation of the railings.

05/20/25

There is no specification or notes on the drawings regarding replacement concrete for the deck. Can either pre-bagged repair mortars or ready mix be used.

Either pre-bagged or ready mix is acceptable as long as it is compatible with the top coat.

05/20/25

During the prebid walkthrough there were noticable cracks in the concrete walkways. It was indicated that these cracks are to be repaired however there are no notes or locations indiacted on the drawings.

Please provide a quantity of cracks to be included in the repairs. Also there is no specification section for crack repair. Do these cracks need to be repaired with epoxy injection / gravity feed or shall they merely be sealed with urethane sealants.

We believe the cracks are superficial and need to be addressed IAW concrete top coat manufactures recommendations.

05/20/25

Demolition note #3 indicates that only areas exhibiting scalling are to be stripped or grinded away down to bare concrete.
