STATEMENT OF WORK

Project No. 528A8-18-807

Fireproofing Repairs - Construction

1. PROJECT DESCRIPTION

The Core 242, 11A, 11B, 11C and 11D mechanical rooms (MERs) have spray fire-resistive material (SFRM) on their roof decks, roof deck’s supporting beams/joists. In total, the rooms comprise of ±11,810 square feet, the rooms contain HVAC, electrical and plumbing equipment. Over time, the mechanical rooms’ SFRM has degraded. This scope is strictly focused on SFRM demolition and application. Due to the extreme construction challenges (conditions of the rooms), the project shall only be bid and conducted by a fireproofing contractor who has documented applied fireproofing experience for a minimum of 5 years, a current, registered NFCA fireproofing contractor for at least 1 year and an approved applicator of Isolatek International – CAFCO products or equivalent. The SFRM material the Contractor specifies must be appropriate for humid environments such as mechanical rooms and can withstand high levels of abuse.

Provide credentials at bidding process. Within the Contractor’s bid, the Contractor shall include the unit cost of SFRM (1-hour fire rating; labor and material) per square foot for demolition and application. The work will be fully described below and shown in detail on the accompanying plans and specifications.

The Scope of Work includes:

1. Only 1 mechanical room can be under construction at a time. The other rooms must maintain their hourly rating as the project progresses.

2. All required reviews shall be scheduled by the project superintendent with a week’s notice.

3. Before demolition can occur, the Contractor shall coordinate with the VA COR and VA shops to de-energize the sprinkler lines in the MER; the Plumbing and Electric shops will de-energize the lines, but the sprinkler heads will remain intact. Once the lines have been de-energized, the Construction shall begin demolition in the specified areas within the MER.

4. Remove existing SFRM (noted as red, shaded cross sections on drawings) on the roof decks, beams/joists supporting the deck and all fireproofing material that has already fallen off.

5. All surfaces/substrates must be clean, free of loose scale, dirt oil, grease, condensation and other substances that would prevent adequate adhesion. This includes untested primers not approved by UL or manufacturer. Refer to UL guidelines when primers are on steel to be sprayed.

6. Notify VA COR to conduct a post-demolition assessment (removal of existing SFRM on application surfaces). If the Contractor fails the review(s), the Contractor is responsible for all associated costs for correcting any failed inspections and shall reschedule another review at their expense. Once the Contractor passes the inspection, the surfaces/substrates can be prepared for application.

7. The Contractor shall implement 110/20 to support their SFRM equipment (pump and mixer).

There are existing receptacles within the MERs that could be implemented for application. If the power from the receptacles is insufficient to power the pump and mixer, the VA Electric Shop will provide temporary feeds from the existing electrical panel(s) in the MER(s). The Contractor shall use their own extension cords from the existing receptacles or temporary feeds to move their equipment to the designated areas of work.

8. Apply CAFCO 400 or equivalent to roof decks and beams/joists. Install per manufacturer’s instructions. SFRM must achieve a 1-hour fire rating. A 1 hour fire rating requires a minimum of ½” of SFRM material to be applied; this can be obtained with 1-2 passes over the designated area.

9. After the Contractor installs the SFRM, the Contractor will notify the VA COR to inspect the areas for thickness and to verify the SFRM has been applied properly. If the contractor fails the review, the contractor is responsible for all associated costs correcting the work and shall coordinate with the VA COR to conduct another review.

10. Once the VA COR approves the installation work in the MER, the Contractor shall vacuum and clean all excess SFRM that did not adhere to the application surfaces. Once the Contractor has finished cleaning, the Contractor shall notify the VA COR and VA shops to re-energize the sprinkler lines. The shops will energize the lines.

11. The Contractor must receive the VA COR’s approval before moving to another MER. If the Contractor has a larger workforce and would like to work in multiple MERs simultaneously, the Contractor cannot delay or stop work in the active MERs or the VA’s fire rating in the MERs would be compromised. Other projects may occupy some of the other mechanical rooms at a given time.

The coordination will be organized by the VA COR.

Background: The Samuel S. Stratton VA Medical Center was constructed in the late 1940’s based upon plans by Green & James, Architects & Engineers, Buffalo, New York and Eggers & Higgins Architects & Engineers, New York, New York dated December 10, 1947. The Core 242 MER was built to provide a space to house air handlers that would support the VA’s imaging wing on 2A.

The mechanical rooms on the 11th floor were built in the 1980’s to provide a space to house air handlers that support the patient wards located from the 7th to 10th floor.

The main hospital and ancillary buildings and services shall remain operational throughout the project.

Existing mechanical and electrical infrastructure are located inside the project spaces and must be protected during the project. Roadway closures will not be permitted at any time or for any reason except with the written approval of the COR.

2. REFERENCES

Perform all work necessary to affect the repair/maintenance items as shown on the attached drawings and further defined in the project specifications. As part of the close-out documentation, the Contractor shall provide as-built drawings in Adobe PDF and AutoCAD 2017 format.

3. ADDITIONAL INFORMATION

The contractor shall provide all labor, supervision and materials necessary to perform the work as indicated in this scope of work, project specifications and drawings. The contractor shall make every effort to maintain the existing conditions that are not part of the project. In addition to following “FAR 52.236- 9, Protection of Existing, Structures, Equipment, Utilities and Improvements” the contractor shall remove or alter existing work in such a manner as to prevent injury or damage to any portions of the existing work, which is to remain. The contractor shall repair or replace portions of the existing work, which have been altered or damaged during construction operations to match existing or adjoining work, as approved by the Contracting Officer and at no additional cost to the government. At the completion of operations, existing work shall be in a condition equal to or better than that which existed before new work started.

The Contactor shall verify all existing conditions on the site and in the facility infrastructure that the proposed project may affect before the commencement of any construction. This includes but is not limited to, verifying the location and elevations of existing utilities, verifying site items as shown on the project drawings and taking appropriate field measurements. The government will not be held responsible for bidding errors made or the failure to adequately inspect the job site for existing conditions, dimensions or to fully review manufacturer’s information related to the project. All bidders are strongly encouraged to inspect the job site prior to submitting bids.

All discrepancies between the drawings, specifications and manufacturer’s recommendations shall be brought to the attention of the Contracting Officer’s Representative prior to bid as a RFI. The Contractor shall abide by the Scope of Work regardless of whether or not a manufacturer calls for the task, level of preparation, etc. in question. The only exception is where the Contracting Officer agrees in writing that the item or task specifically voids a manufacturer’s warranty and may be omitted. A credit for the work not performed may be due to the government in such circumstances at the discretion of the Contracting Officer.

All drawings notated with “install, application, replace, provide or new” infer that the Contractor is responsible for providing all materials and labor associated to complete that task or phase of the project as well as the project overall.
