Section 01 33 00 (Submittal

Procedures).

A full roof replacement is not included in this project's scope of work. The contractor is not responsible for pre-existing leaks or wear-and-tear; however, you are strictly responsible for protecting the roof during construction (e.g., during RTU lifts and rigging) and repairing any fresh damage caused by your operations. Additionally, you are responsible for ensuring all new roof penetrations and equipment curb modifications are 100% watertight.

Question

Curb adapters are the responsibility of whom?

Answer

The General Contractor is fully responsible for providing, installing, and sealing any required curb adapters. The GC's hired

Structural Engineer must evaluate the existing curbs and proposed adapters to verify structural integrity before any new RTUs are set.

Question

What is the extent of contractor responsibility for existing roof deficiencies discovered during RTU replacement?

Answer

The contractor is not responsible for pre-existing leaks or structural deficiencies unrelated to their work. However, the contractor is responsible for ensuring all new roof penetrations and curb installations are 100% watertight, and for repairing any damage to the existing roof system caused by construction operations. Bidders should include a reasonable contingency for minor repairs. If a curb or structure is found to be fundamentally deficient post-award, this must be documented and communicated to the Contracting Officer prior to proceeding.

Question

Is the Contractor required to retain a licensed Structural Engineer to perform roof load calculations and provide signed/sealed certification of the existing roof structure?

Answer

Yes. The General Contractor is required to hire a licensed Structural Engineer to analyze and verify the integrity of the roof structure to confirm it can safely support the loads of the new RTUs

Question

If so, what specific deliverables are required (calculations, drawings, certification letter, stamped report, etc.)?

Answer

The hired Structural Engineer must perform a comprehensive structural analysis. The required submittal deliverables include a stamped structural calculations package and a signed/sealed structural verification report confirming that the existing roof system is structurally adequate to support the new RTU loads.

Standard field verification requirements.

Specification Section 01 11 00.

Specification Section 01 35 26 and

Section 01 45 00

Is the Structural Engineer required to perform field observations and provide final certification after installation

Answer

Yes. The structural verification process is a post-award requirement. The engineer must conduct necessary field verification and analysis to submit their approved report prior to lifting and setting the new units, and perform any required follow-up field observations to issue final certification of the installation.

Question

Does the Government possess any existing structural calculations or roof-load information that can be provided for use during design verification?

Answer

No existing structural calculations, roof-load data, or structural "as-built" drawings are available. The contractor's structural engineer must perform all necessary field verification, measurements, and calculations independently to complete the structural submittal.

Question

Has the Government already retained a Fire Protection Engineer for this project, or is all FPE support the responsibility of the Contractor?

Answer

The Government has not retained an FPE for this project. It is the sole responsibility of the General Contractor to hire an independent, qualified Fire Protection Engineer (FPE) to complete all inspections, testing, and tasks described in the specifications.

Question

Please clarify whether the Superintendent, Quality Control Manager (QCM), and Site Safety & Health Officer (SSHO) are required to be separate individuals, or if one person may perform multiple roles provided, they meet all qualification requirements

Answer

On this project, the roles of the Site Safety and Health Officer (SSHO) and the Quality Control (QC) Officer may be combined and fulfilled by a single qualified individual, provided they meet all specification requirements for both positions. However, the

GC Superintendent cannot serve as the SSHO. Therefore, a minimum of two (2) dedicated key personnel are required on-site:

one (1) Superintendent and one (1) combined SSHO/QC Officer.

Question

Please confirm whether the Contractor is only required to coordinate and verify operation of existing fire alarm interfaces associated with HVAC equipment and dampers installed under this contract?

Standard field verification requirements; Drawing A-102.

Yes, the new flooring is only intended to be installed within the boundaries indicated by the linework on the drawings, acting as a localized patch/repair resulting from the construction activities, not a full-room replacement. You are correct in standard assumptions: match the existing adjacent corridor flooring (typically VCT) and the existing adjacent classroom flooring

(typically carpet). The contractor is responsible for field-verifying the exact existing material types and boundaries to ensure a seamless patch

Question

On the demolition drawing AD103, note 4 indicates to replace any ceiling tiles damaged during HVAC replacement and to replace any water damaged ceiling tiles through-out. Please provide the number of water damaged ceiling tiles that require replacement or provide an allowance to cover this unknown requirement.

Answer

Drawing G-002, in the "Project Summary" section, states, "ceiling tiles show water damage..." Bidders are responsible for their own site verification. The scope includes replacing these identified water-damaged tiles plus any tiles damaged by the contractor during construction activities. Recommend additional site walk if needed

Question

There is a Paints and Coatings specification (09 90 00) but there is no painting work shown in the drawings. Please advise.

Answer

Painting is required for the restoration of existing surfaces affected by the work. When old mechanical equipment, thermostats, ductwork, or electrical panels are removed or relocated, the contractor must patch, prep, and paint those affected wall or ceiling areas to match the surrounding finishes. Section 09 90 00 governs the quality and application of these touch-ups.

Question

Sheet A-102, General Note #7 – Should contractor assume to replace all roofing at curbs? If not, how many locations should contractor assume to be replaced?

Answer

The contractor is not replacing the entire roof. You are only required to replace/patch the roofing system directly at and immediately surrounding the curbs that are being utilized, modified, or newly installed for the RTUs and exhaust fans. The number of locations directly correlates to the number of rooftop equipment items shown on the Mechanical Roof Plan

Question

What is the existing roof construction type?

Answer

Specific composition details of the existing roof are not explicitly detailed in the provided architectural roof plans. It is the responsibility of the contractor to field-verify the existing roof membrane type (e.g., EPDM, TPO, Modified Bitumen) and underlying construction during the site visit to ensure that all proposed patching materials and curb flashings are fully compatible and maintain the watertight integrity of the roof

The civil scope for the wet well is strictly limited to the demolition and replacement of the duplex grinder pumps, slide rails, discharge piping, valves, and electrical connections as detailed

Question

Is a single bypass pump acceptable or are 2 required?

Answer

Yes, a single bypass pump is acceptable, provided that the contractor implements a strict daily monitoring and maintenance protocol to ensure its continuous, trouble-free operation throughout the duration of the bypass period.

While a single pump is authorized, the General Contractor (GC) remains 100% liable for maintaining uninterrupted sewer service and must have an immediate contingency plan in place to resolve any pump failures or blockages before a backup or environmental spill occurs.

Question

The General Not 1 on Sheet A102 requires the Contractor to ensure that the Roof does not leak once the Mechanical renovation is complete. Are we to assume that the roof is currently watertight and if any leaks develop after the construction that we are responsible for the repair of the entire roof?

Answer

The contractor is responsible for ensuring all new roof penetrations and curb installations are 100% watertight. You are also responsible for repairing any damage to the existing roof system caused by your operations. You are not responsible for pre-existing leaks unrelated to your work, but you must document and report any such conditions to the Contracting Officer prior to starting work.

Question

What is the condition of the existing roof? Is it under warranty? If so, who is the responsible warranty contractor?

Answer

The condition and warranty status of the existing roof is not known. Bidders should base their proposals on the information available in the contract documents and their own site investigation

Question rawing A-102 (General Note 5).

Drawing A-102 (General Note 6).

FAR 52.236-2, Differing Site

Conditions.

Answer

Yes, this is a post-award requirement that must be completed prior to setting the new equipment. The intent of the note is to ensure structural verification occurs. The contractor’s hired Structural Engineer must perform their analysis and submit their verification report for review and approval before the new units are lifted and installed.

Question

General Note 6 on A102 requires ensuring existing curbs are structurally sound. If curbs are found deficient, will the contractor be paid to support or repair them?

Answer

The contract requires ensuring the reused curbs are sound. Bidders should include a reasonable contingency in their bid for minor repairs. If, after award, the contractor's structural engineer determines a curb is fundamentally deficient and requires substantial reconstruction beyond typical preparation, this condition should be documented and communicated to the

Contracting Officer as a differing site condition.

Question

Are “As-Built” drawings that show the depths of the existing drain lines available? These are necessary to determine the width of the trench needed to replace the UG drain piping.

Answer

No as-built drawings showing the depths of existing lines are available. The contractor is responsible for all field verification, including locating and determining the depth of existing utilities, as stated in the drawings.

Question

The General Note 1 on Sheet PD 101 and several other sheets states “. ALL PLAN DATA BASED ON SITE SURVEY AND

GOVERNMENT PROVIDED DRAWINGS. CONTRACTOR MUST VERIFY AND BECOME TOTALLY FAMILIAR WITH ALL EXISTING

CONDITIONS AND DIMENSIONS PRIOR TO COMMENCEMENT OF WORK”. This statement by the AE appears to shift design responsibilities from the DOR to the Contractor for ALL CONDITIONS that are discovered and not shown. Please ensure that the contractor WILL NOT be held responsible for unforeseen site conditions or items not clearly identified in these 100%

Design drawings.

Answer

This is a standard clause requiring the contractor to be familiar with the site. The contract provides a process for addressing differing site conditions that are genuinely unforeseen and not indicated in the contract documents. The contractor is not expected to assume design liability but is responsible for a thorough review of the documents and the site.
