REVISED STATEMENT OF WORK

Bldg. 10A, Flooring Repair and Replacement

A. GENERAL INFORMATION

a. Purpose The purpose of this requirement is to repair the Luxury Vinyl Tile (LVT) flooring in designated areas of Building 10A of the Carl Vinson VA Medical Center. This effort is necessary to address ongoing patient safety concerns resulting from the LVT flooring bubbling, swelling, and detaching from the subfloor, which has created documented hazards for staff, visitors, and patients.

b. Site Visit Though not mandatory, contractors are encouraged to attend the site visit at the station.

Date: Tuesday, September 29, 2026 Time: 8:00AM EDT Location: Carl Vison VA Medical Center, 1826 Veterans Blvd, Dublin GA. 31021 (Meet staff at from of VA Medical Center).

Questions & Answers:

Questions about this solicitation will expire on September 30, 2026 at 11:00AM EDT and no questions will be accepted after the expiration date and time. However, answers to the questions will be provided to the offeror after the expiration date and time.

c. Background The LVT flooring in select areas of Building 10A has been the source of repeated complaints due to visible bubbling and detachment from the subfloor. These conditions have progressively worsened and recently led to a formal Patient Safety Report being filed, highlighting the risk of trips, falls, and mobility challenges for patients and staff. These conditions are suspected to be caused by moisture present within the subfloor causing the LVT planks to swell and detach.

To resolve this issue and prevent future concerns with patient safety and staff mobility, the Carl Vinson VA intends to repair these sections of damaged LVT flooring by patching with new LVT flooring in select areas and incorporating a moisture-control membrane as part of the repair process to prevent future occurrences of this issue.

d. Scope of Work The contractor shall provide ALL labor, materials, tools, equipment, transportation, and supervision necessary for repair of the damaged and swelling LVT flooring including proper subfloor preparation, moisture-barrier application, all aspects of applying new LVT in the affected areas, and site cleanup. The contractor shall remove damaged LVT floor planks and associated adhesives from the designated areas. This includes transporting and disposing of all waste in compliance with local, state, and federal regulations. The contractor shall inspect the underlying concrete subfloor after removal of the damaged LVT to identify any cracks, uneven surfaces, or damaged substrate conditions requiring patching or remediation. Any and all subfloor preparation necessary to ensure proper adhesion and performance of the moisture barrier and LVT flooring planks shall be completed as part of this effort.

Specific Contractor responsibilities will include, but are not limited to, the following:

1. Complete removal of the damaged LVT in the designated areas identified in the Building 10A West floor plan

2. All subfloor preparation measures after removal of damaged LVT, including removal of any residual glue or other adhesives from the subfloor

3. Application of a moisture barrier over the subfloor; specifications and requirements are described in the “General Requirements” section below

4. Installation of the new LVT flooring product, ensuring proper adhesion to the subfloor

5. All necessary trim work around walls, baseboards, around doorways, etc.

6. Complete removal of debris and waste off-site, either through daily transportation off-site or through another Contractor-provided means (i.e. a dumpster supplied by the Contractor)

e. Performance Period This will be a One-Time Service Contract. All work shall be completed within forty-five (45) days from the date of contract award.

In the event that conditions arise that are expected to significantly impact the POP – including but not limited to unforeseen subfloor conditions, discovery of hazardous materials, significant dust/debris generation requiring an ICRA, or material lead time exceeding the 45-day POP – a reasonable time extension will be issued as necessary to accommodate the delay. The Contractor shall notify the Contracting Officer’s Representative (COR) in writing as soon as such a condition is identified, including the anticipated cause and estimated duration of the delay, so that an appropriate extension can be evaluated and approved in a timely manner.

f. Location of Performance Building 10A West, located at the rear of Building 10 of Carl Vison VA Medical Center, 1826 Veterans Blvd. Dublin, GA 31021

B. GENERAL REQUIREMENTS

a. Flooring Requirements The approximate total square footage of LVT flooring to be replaced is ~4,850 SF. The Contractor shall include an appropriate amount of extra material in their bid to accommodate for damaged/defective products; the exact amount of extra material is to be determined by the Contractor. Prior to contract closeout, all new and unused LVT supplied by the Contractor shall be given to the VA for storage and future use.

The Contractor shall supply and install the LVT flooring product specified in this Statement of Work for patching of damaged floor areas. The LVT product that will be used is “Karndean Van Gogh – gluedown – Wellington Oak”; the Karndean product code is “VGW53T”.

The Contractor MUST supply and use this specific LVT product. Any flooring product other than the Karndean product specified above will not be accepted and failure to supply this specific product with the product code stated above will be considered a failure of performance, resulting in contract termination.

This LVT product is a glue-down floor plank. The Contractor shall be responsible for selecting and supplying a glue/adhesive that is fully compatible with both the LVT product and the liquid-based moisture barrier/mitigation system applied to the concrete subfloor, and that meets all applicable manufacturer specifications and installation requirements for each. It is the Contractor's sole responsibility to verify compatibility between the adhesive, the LVT product, and the moisture barrier system prior to installation, including confirmation with the LVT and moisture barrier manufacturers as needed, to ensure proper bond performance and warranty compliance if included.

The Contractor shall be responsible for purchasing, supplying, and transporting the selected LVT flooring, as well as any and all other materials necessary for the installation, including but not limited to adhesives, moisture barrier materials, transition strips, reducers, and any tools or equipment required to complete the work. The Contractor shall also be responsible for all labor associated with removal and disposal of existing flooring and installation of the new LVT flooring in all designated areas. The VA will not purchase, provide, transport, or supply any materials, tools, or equipment needed for this project; all such items shall be furnished solely by the Contractor.

Floor repair shall include proper trimming, transitions, and finish work to ensure the flooring is secure, level, and free of aesthetic and functional defects. If a concern is raised or an aesthetic or functional defect is identified with any portion of flooring laid by the Contractor, the Contractor shall address the concern and redo any section of flooring identified by VA engineering/maintenance staff as directed. The Contractor is also responsible for verifying that all restoration practices comply with any applicable building codes, safety standards, and manufacturer specifications.

The Contractor shall remove and dispose of the damaged LVT flooring sections in a safe and efficient manner. Any damage that occurs to the subfloor, walls, or any other surfaces or equipment of the facility shall be repaired and restored to its original condition at the sole expense of the Contractor.

b. Subfloor Preparation & Moisture Barrier Application Upon removal of the damaged LVT flooring sections, any residual glue or other adhesives must be adequately removed so as to not hinder the application of new LVT for patching or create high/low spots on the floor.

The Carl Vinson VA is in the process of obtaining moisture testing results for the concrete subfloor in Building 10A West. However, moisture testing results are not expected to be obtained before contract award. As a result and as a precautionary measure, the Contractor will be required to apply a moisture barrier membrane over the concrete subfloor to prevent any moisture issues from arising in the future.

The moisture barrier product to be supplied and installed by the Contractor shall be MAPEI Planiseal Max. Should the Contractor determine that this product is incompatible with the specified LVT flooring, the selected adhesive, or the subfloor conditions, and therefore unsuitable for this application, the Contractor shall provide written justification identifying the specific compatibility issue prior to substituting an alternative product. Any substitute moisture barrier must be a water-based mixture formulation to ensure compatibility with the glue-down LVT installation, and the Contractor remains responsible for verifying and documenting that the substitute product is fully compatible with both the LVT flooring and adhesive selected for this project.

The moisture barrier shall be installed in strict accordance with the manufacturer's specifications and installation guidelines. The Contractor shall verify proper curing of the barrier prior to proceeding with adhesive and LVT installation. The Contractor is fully responsible for confirming that the moisture barrier is continuous and uniformly applied across all areas receiving new LVT, free of gaps, voids, or inconsistencies in thickness that could result in high or low spots in the finished floor.

c. Floor Transitions & Reducers All new LVT must transition seamlessly with adjacent flooring that is not included in the scope of work. The application of the moisture barrier combined with the thickness of the selected LVT product may create a slightly higher or lower finished floor elevation than the adjacent surfaces. To address this, the Contractor will be required to lay a reducer or transition strip where necessary to ensure that all transition points are smooth, level, and properly finished to eliminate tripping hazards for patients and staff.

The Contractor will be responsible for selecting and installing an appropriately colored, designed, and sized reducer/transition strip for transition areas. Reducers selected for use by the Contractor for must be low-profile and must support safe movement for patients, staff, and equipment, maintaining consistent floor continuity throughout the facility.

No finished work that presents a safety hazard for the mobility of patients and/or staff will be accepted. VA personnel will determine if a transition area or reducer installed by the Contractor presents a safety/mobility hazard, and if it is determined that the installed product is unsafe, the Contractor shall replace the reducer to create a smoother/safer transition at no additional expense to the Government.

d. Walls & Trim Work Due to the difference in thickness of the new LVT flooring relative to the existing floor finish, the existing 4" cove base and millwork baseboard (where present) will no longer align flush with the finished floor surface once the new flooring is installed. The Contractor shall remove and replace all existing cove base and millwork baseboard in the areas receiving new LVT flooring, rather than attempting to lower or re-set the existing material, as the resulting unpainted or unfinished wall surface previously concealed behind the base trim will remain exposed and visible at the new, lower floor height. Replacement base trim shall be installed in a taller profile – a nominal 5" or 6" height, as needed – sufficient to fully conceal the exposed, unfinished wall area above the prior 4" base line and provide a clean, finished transition down to the new floor surface.

Due to the taller base requirement, wall trim pieces (such as outside corner trim) may need to be trimmed, cut down, or otherwise modified to properly fit and align with the new, taller base profile. The Contractor shall be responsible for cutting, modifying, or replacing any adjacent trim as needed to achieve a clean, properly fitted transition at all corners, door casings, and other trim intersections. Where existing trim cannot be modified to accommodate the new base height without a visibly compromised fit or finish, the Contractor shall replace the affected trim piece in its entirety, matching the existing material, profile, and finish, and shall notify the VA COR of any such locations prior to proceeding.

All replacement base and trim shall match the existing material type, color, and profile on a like-for-like basis: areas currently finished with cove base shall receive new cove base of matching profile and similar color, and areas currently finished with millwork baseboard shall receive new millwork baseboard matching the existing profile, material, and finish. The Contractor shall field-verify existing base trim type, color, and profile in each affected area prior to ordering replacement material to ensure an accurate and consistent match throughout the project scope.

If any wall damage occurs during removal of baseboards or any other trim, the Contractor shall be responsible for patching, skimming, and sanding the damaged area to restore the wall surface to its prior condition, smooth and ready for finish. The VA Paint Shop will repaint areas where patch/skim work has been performed; the Contractor shall notify the VA COR upon completion of each patched area so that repainting can be scheduled and coordinated accordingly. The Contractor shall ensure all patched surfaces are fully cured and properly prepared prior to this notification, as the VA Paint Shop will not be responsible for additional surface preparation beyond standard painting procedures.

LVT flooring near the base of the metal door jambs in all doorways must be cut to fit the profile of the door jambs and door trim as closely as possible. Gaps between LVT flooring and the door jambs and trim shall be no larger than 1/8”. The Contractor must fill in gaps between the flooring and door jambs and door trim with silicone or caulk that closely matches the color of the Karndean Wellington Oak flooring product. If any gaps between the LVT and the door jambs are determined to be larger than 1/8”, the Contractor shall recut and replace these floor planks at no additional charge.

e. Containment and Infection Control The current LVT flooring is reportedly detaching from the subfloor in the areas scheduled for replacement and is expected to be removed with minimal effort. Based on this condition, no additional infection control and/or dust containment measures beyond basic containment practices are currently anticipated for this phase of work.

Should conditions arise during removal or installation that are expected to generate significant dust or debris – such as unanticipated adhesive removal, subfloor preparation, or concrete grinding – the Contractor shall notify the COR so that an Infection Control Risk Assessment (ICRA) and any additional containment measures can be evaluated and implemented as appropriate.

f. Site Cleanup & Waste Removal The Contractor shall be responsible for cleanup and proper disposal of all waste/debris created throughout the entire duration of the contract. Removal and disposal of waste shall be done in full compliance with any applicable local, state, and federal regulations. The Carl Vinson VA shall not be responsible for any site cleanup or disposal of any waste and debris created as a result of the work performed by the Contractor.

The Contractor will be required to perform daily cleanup of the worksite. No trash or debris shall be left laying in hallways, rooms, other interior spaces, or outside of the building in any areas. In addition to daily cleanup, the Contractor shall also perform a final site cleanup upon project completion prior to contract closeout.

The Contractor shall be responsible for acquiring any equipment for waste disposal as necessary. The Contractor can either dispose of and transport any waste/debris off-site daily or provide a dumpster to be placed near the building for waste disposal. The VA will not be responsible for providing any means for waste disposal, including a dumpster.

If the Contractor decides to provide a dumpster for waste disposal and removal, it should be appropriately sized and the location of the dumpster shall be coordinated by the Contractor with the COR at least a week in advance prior to dropoff.

g. Site Access, Coordination, and CVVAMC Assistance The COR will serve as the primary Point of Contact (POC) and acceptance authority.

The Contractor shall coordinate all work schedules with the COR and other VA facility staff as necessary. Prior approval from the COR is required before beginning any work, including site preparation, to ensure all affected VA staff have been provided advance notice and given sufficient time to relocate patients from the work area if necessary. No work will be permitted without prior coordination with and obtaining approval from the COR.

Patients are currently scheduled to be kept out of the work area until contract closeout. If it is determined by VA staff that the work must be performed in sections of the building at a time rather than all at once, this will be communicated to the Contractor in advance and the Contractor shall put up signage, barriers, and make any other necessary adjustments to secure the active work area.

The Contractor must check in with the COR or other designated personnel daily upon arrival at the facility. The check-in method will be up to the COR’s discretion. Failure to comply may result in a response from VA Police or other facility personnel.

It is the vendor’s responsibility to properly assess the working conditions and include in the bid any specialty equipment, training, additional time, personnel, or safety equipment to perform the work safely and in compliance with all applicable local, State, and Federal regulations.

The VA will not be responsible for storage of equipment, materials, or tools.

h. Other Requirements

The Contractor shall follow all safety measures to ensure a safe working environment for all involved. The Contractor is expected to always keep the work environment clean and safe.

Employees of the Contractor and Sub-Contractors shall always conduct themselves in a professional manner while on medical center property. The vendor shall ensure all personnel working on this contract are aware of Medical Center rules pertaining to employee behavior and conduct. Physical or verbal misconduct may be grounds for removing employees from Medical Center property, or grounds for arrest by the VA Police. Employees may be banned from Medical Center property as a result of inappropriate or illegal behavior. The vendor shall not be entitled to any compensation from the Government for any costs resulting from employee misconduct (including, but not limited to, delays in contract completion) and may be held liable for costs incurred by the Government as a result of employee misconduct.

Hospital operations and patient care shall take priority. Any anticipated disruptions to normal operations must be communicated and approved by the COR and other VA personnel as necessary. The Contractor shall take any measures necessary to ensure that patient care services are uninterrupted and unaffected by the work being performed.

Failure to comply with any requirements stated within this SoW is grounds for a negative performance to be documented in the past performance reports (CPARS) system and/or contract termination.

C. CHANGES TO STATEMENT OF WORK (SOW)

Any changes to this SOW shall be authorized and approved only through written correspondence from the CO. A copy of each change will be kept in a project folder along with all other products of the project. Costs incurred by the Contractor through the actions of parties other than the CO shall be borne solely by the Contractor.

D. SECURITY

a. General Contractors, Contractor personnel, subcontractors, and subcontractor personnel shall be subject to the same Federal laws, regulations, standards, and VA Directives and Handbooks as VA and VA personnel regarding information and information system security.

E. Parking/Laydown Area The Contractor shall make necessary arrangements for parking.

END OF REVISED STATEMENT OF WORK

October 23, 2026

Ms. Zelia Petty

Occupational Safety and Health Carl Vinson VA Medical Center, 1826 Veterans Blvd.

Dublin, GA 31021

Subject: Concrete Moisture Testing Building 10A Carl Vinson VAMC Dublin, Georgia Project Number AAB-26-130

Ms. Petty:

Above and Beyond Contracting (AAB) conducted moisture testing of concrete floor at Building 10A, located at the Carl Vinson VA Medical Center in Dublin, Georgia. This assessment was performed on October 15, 2026, at your request. This information was requested as part of the upcoming project to install new floor coverings by another contractor. The results of the moisture testing will assist the contractor in complying with floor manufacturer’s installation requirements.

Methodology:

Upon arrival, AAB was directed to Building 10A area of concern (AOC). AAB conducted the testing in general compliance with ASTM F-2170 standard. That standard calls for users to make at least three holes in the first 1,000 sq. ft. of concrete being tested, and one more hole per 1,000 additional sq. ft. of concrete slab. So, if you had a slab of concrete covering 2,000 sq. ft., you would need to prepare at least 4 holes in the concrete. AAB identified 4 sample locations for this testing period as listed below.

Process First, we drilled to the required depth of 4 inches using a rotary hammer drill and a three-quarter inch drill bit.

A rotary hammer drill with a drill bit that has 3 or 4 cutting edges is recommended to ensure a smooth, round hole that will conform to the sleeve.

Second, we vacuumed the hole thoroughly to remove dust particles from within the hole. Then, we used a ¾ inch wire brush to clean out or loosen any concrete chips remaining in the hole. Vacuum again to clear out the remaining concrete. We used the insertion tool from the sampling kit to verify the correct diameter of the hole drilled.

Third, we installed the RH 16 sensor into the concrete after confirming the sensor is working by taking a reading using the RH Total Reader prior to inserting the sensor in the hole. Next, we inserted the Rapid RH sensor to bottom of 4-inch concrete hole. Then we installed the sensor cap to the top of the sensor hole.

Finally, after the cap is applied (or the in-situ probe is installed) the hole should be left to acclimate for no less than 24 hours to allow the smart sensor to equilibrate according to ASTM F2170 standard. After that 24-hour waiting period readings can be made up to 30 days without any additional equilibration time. To take a reading the RH6 Total Reader was inserted in the hole where the sensor is placed. The LCD display will toggle between the RH % reading and the degree temperature readings and shutoff after one minute. The readings are then recorded and documented for reporting purposes. See the recorded results for the testing performed at Building 10A below.

AAB utilized Wagner Concrete Moisture Test Starter Kit+ with Rapid RH® L6 as test kit to meet the ASTM F2170 standard for this project. This Kit provide results for relative humidity and temperature. The following represents the results:

Sample Location Sample Reading 161-10 Hallway 73 % RH/Temperature 69 degrees 165-10 Living Room entrance 74 % RH/Temperature 69 degrees 150-10 Hallway No Reading made 10A Entryway Door 68% RH/Temperature 70 degrees

Conclusions & Recommendations:

AAB has endeavoured to perform moisture testing in general compliance with ASTM F2170 standard to provide useful information to the end users installing new flooring as per manufacturers requirements. The sampling tools used allows for ongoing monitoring of the moisture readings Relative Humidity (RH) and temperature for up 30 days. It is recommended that additional readings be collected to see if conditions change over time prior to installing the new floor coverings.

Thank you for this opportunity; we are available immediately to discuss the findings and recommendations in this report.

Sincerely Herman Kitt
