RFI # RFI Question Government RFI Response Notes

Since we were not allowed to core cut the roof, can you please provide existing roof system?

The Governement has no verified existing information regarding the exisiting assembly of the roof. The Government intentionally did not authorize destructive roof core sampling prior to bidding due to the potential presence of asbestos-containing materials (ACM) within the existing roofing assembly.

Could you please clarify whether Sierra North may submit a bid under our Class B license (with or without a properly licensed C-39 subcontractor), or whether the bid must be submitted directly by a contractor holding the C-39 license?

The Government will accept a California Class A or B, or C-39 contractors license from offerors. Offerors must hold the license, not sub contracors.

The Prime Contractor has an active and valid California General Contractor License. Our key suubcontractor maintains an active and valid California C-39 Roofing Contractor contractor’s license. Is this acceptable for submission?

The Government will accept a California Class A or B, or C-39 contractors license from offerors. Offerors must hold the license, not sub contracors.

For the requirement to “furnish a list of three (3) projects of similar magnitude completed by the firm,” does the term “firm” refer exclusively to the Prime Contractor, or may relevant project experience from key subcontractors also be included in the submission to demonstrate overall team qualifications and past performance?

Past performance must be of the offeror, not proposed subcontractors.

Please confirm whether the exterior lighting replacement is intended to be a complete design-build electrical scope, including circuit tracing, panel capacity verification, new branch circuits, conduit routing, controls, grounding/bonding, nighttime aiming, and photometric verification.

Yes. The electrical portion is performance-based. The Contractor shall provide all engineering, circuit tracing, panel verification, conduit routing, controls, grounding, testing, aiming, and associated work necessary to provide a complete code-compliant installation.

Please provide existing electrical drawings, panel schedules, circuit information, and any available as-built drawings for the existing roof-mounted HPS lighting and building perimeter lighting circuits.

No electrical as-built drawings, panel schedules, or circuit documentation are available. The Contractor shall field verify existing conditions.

Please confirm whether a specific fixture manufacturer/model is required for the twelve new LED floodlights, or whether contractor-selected commercial-grade wet-listed fixtures meeting the stated performance requirements are acceptable.

Contractor-selected commercial-grade fixtures are acceptable provided they meet or exceed the performance requirements specified in the SOW.

Is a stamped lighting/photometric plan required, or is field aiming and visual/nighttime verification acceptable?

A stamped photometric plan is not required. Field aiming and nighttime verification demonstrating acceptable illumination are sufficient.

Option A.1 requires pricing for asbestos abatement and disposal for the entirety of roof materials under worst-case conditions. Please confirm whether this option should assume all roof membrane, flashings, mastics, penetrations, and associated roofing components contain asbestos.

Yes. For pricing purposes only, Option A.1 shall assume worst-case conditions associated with roofing-related ACM. Actual abatement work will be determined by the required asbestos survey.

Please clarify the expected extent of tapered insulation, crickets, saddles, and drainage improvements. Are bidders to include a full tapered insulation design, localized crickets only, or an allowance?

Include tapered insulation, crickets, saddles, and drainage improvements necessary to eliminate or minimize ponding and satisfy the roofing manufacturer's warranty requirements.

Please clarify the required extent of roof hatch refurbishment, ladder refurbishment, and hatch guardrail replacement, including whether existing components are to be repaired, recoated, replaced, or brought fully into current Cal-OSHA compliance.

Refer to section 3.1.4 of the SOW.

The SOW says to clean out concrete drains and replace grates. Is this still a requirement? How many grates are to be replaced?

No coring of the roof was able to be taken, what thickness is the existing roofing for demolition costs when submitting proposal?

Refer to Response No. 1. Existing roof thickness has not been verified.

No coring of the roof was able to be taken, what is the existing type of deck?

Concrete, metal, or wood?

Refer to Response No. 1. Existing deck type has not been verified.

With the original roof hatch having the electrical lighting conduits going through the side. For warranty and long-term waterproofing purposes, will the contractors be required to remove and replace the existing hatch?

No. The Government is not requiring replacement solely due to the conduit penetrations. The Contractor shall propose a manufacturer-approved solution that maintains the roofing warranty and long-term watertight integrity.

16 Are roof anchors optional or required?

Roof anchor points are optional and will only be installed if authorized by the Government.

Please confirm whether the interior ladder and roof hatch are the only approved access points for contractor use? Or will exterior be permitted under Government escort?

Refer to section 3.0 of the SOW.

The Administration Building is expected to remain occupied during construction. Refer to section 3.0 of the SOW.
