• It will be the contractor’s responsibility to verify all dimensions and quantities prior to bidding on this contract and any discrepancies should be brought to the attention of the

COR.

• Warranty and use of paint, primer, paint remover, sealers, caulks, adhesives to be used and supply COR with SDS of each product before use.

• Documentation of proper respirator use and care. Furnish the COR with updated first aid plan for project before work begins.

• Certification for removal of lead base products and paints (manifest).

SCOPE OF WORK:

Remove lead paint from all areas that test positive such as windows, doors, support beams, ceiling boards and trim using prescribed method such as Peel- Away, or an approved equal and prime surface then re-paint surface with an exterior latex high quality paint. All other surfaces that may not contain lead paint but will be tested to ensure no lead is present, could including siding, fascia, moldings, bargeboards, etc., do require paint removal and are to be prepared for painting and repaint. This preparation includes scraping, feathering, and thoroughly washing.

The paint type is specified below and Contracting Officers Representative, (COR) will select colors. Re-Paint all areas to include but not limited to: entrance doors, door jams, trim soffits, fascia, trim, rake boards and windows. The contractor will furnish, remove and replace all broken window glass panes before glazing and repainting. Throughout the paint removal process, a construction grade of plastic shall be placed under and around the area being worked on to catch any paint chips that fall to the ground. Upon completion of each day’s work, all plastic shall be removed, and the paint chips placed in approved containers for proper disposal

Due to excessive painting over the years, much of the details of profiles on this woodwork have been lost. As typical for this amount of paint build-up, the effect of layering and alligatoring is evident. Presently, most of the paint surface is sound with peeling and cracking in isolated spots.

Due to the age of the building most of the painted surfaces are lead containing with different concentrations in different areas. Also included in this contract is the consolidation of all wood surfaces due to rodent damage or rotten wood. There is some damage to casement windows, door and window trim as well as fascia. Any damage shall be sanded to a smooth and even surface and then consolidated using an approved wood consolidate, such as Abatron two-part epoxy, or an approved equal, as per manufactures recommendations. Once consolidated all profiles shall be reconfigured to the exact profile, matching the existing line and curves straight and true. In places where consolidation is not possible, the contractor shall remove the damaged wood and replace it with an exact molding profile and wood species, or an approved equal. Dutchman joints will be made at 45-degree angles by either sawing or chiseling. These joints are to be connected using approved exterior glue or adhesive with the addition of appropriate finish nails.

All replacement work is to be done after the paint is removed so the exact lines of the molding profiles are clearly defined, and the chemical process of removal will not hinder the adhesive connection of the joints. Once repairs are made to the damaged wood, all fresh wood surfaces shall be primed with one coat of lead lock primer and followed by two coats of latex-finish paint.

All exterior window surfaces, door surfaces, and jams shall be completely stripped of paint. The Contractor will be responsible for the covering up of all exterior brick surfaces to protect them from the stripping and painting process. Any damage to the bricks will be the contractor’s responsibility to repair immediately to the approval of the COR.

Upon completion of preparatory work all surfaces shall be brush washed to remove any dust or dirt, providing a clean and smooth surface for painting. No painting can begin until the wood has had sufficient time to dry, and the new paint can be applied according to the manufacturer’s recommendations. All scraped surfaces are to be wet sanded and feathered to a smooth, even surface. Any weather stripping that is damaged during this process shall be replaced by the same, or an approved equal. Because this structure is used as a visitor contact station, the successful bidder will be required to provide all measures necessary to protect the visitors, park employees, And workers from any lead exposure. If any restroom areas are to be closed for paint removal or repainting process. Contractor will be responsible for furnishing temporary restrooms (Porta- Potty) and hand washing stations for public use while work is being performed at contractor’s expense. Contractor will be responsible for furnishing contract workers (employees) restroom and hand washing station when working in remote areas of the park at contractors’ expense.

EXECUTION

PREPARATIONS FOR PAINT REMOVAL

Are to include the following measures, in addition to those called for in Regulations and Recommendations cited above:

Interior Sealing of Windows and Doors and Cracks: Contractor is to seal all windows, non-operating doors, and cracks on interior wall face with two layers of polyethylene (min. 6 mil) plastic sheeting. Possible means are industrial grade staples and duct tape, but final result must be complete sealing of openings against entry of lead dust from paint stripping while at same time protecting interior millwork from damage from fasteners.

Interception of Lead Paint Particles Falling on:

Ground or Paving: Particles and debris generated by stripping of exterior millwork are to be caught on plastic sheeting laid at base of exterior face of walls. This plastic sheeting is to consist of two layers of six mil (minimum) polyethylene plastic, which are overlapped six inches, taped together with duct tape, and weighted down on all sides. At face of wall, plastic sheet is to be secured to wall with tape or other means that will not leave marks on wall.

Shrubbery: Lead paint particles are to be caught before falling on shrubbery by two layers of polyethylene overlapped and taped as described above, but supported on scaffolding, or some sort of framing. As describe above, plastic at face of wall is to be fastened to wall to prevent lead paint particles from falling down behind shrubbery.

Personnel Protective Practices Contractor and his personnel are to wear all recommended protective gear including as a minimum that listed in paragraph 2-1 above.

Contractor and his personnel shall remove, dispose, and double bag in six mil polyethylene plastic bags all protective clothing items at the end of each day in dressing room set aside for that purpose by National Park Service.

Contractor personnel shall not eat or smoke in work area, but in area designated by the National Park Service.

Using Methods Minimizing Dust Generation Contractor's personnel must use stripping and paint removal methods that will hold down the generation of lead particle dust by:

Dampening painted surfaces with a fine water mist from a garden sprayer during scraping and/or hand sanding.

Using only manual methods; no power tools or sandblasting.

Using heat gun. Using heat guns is not permitted

DISPOSAL OF LEAD PAINT PARTICLES AND DEBRIS

Clean debris and particles from surfaces as work progresses using high-efficiency particulate air filter vacuums (HEPA vacs), and wet washing with high phosphate cleaning mixture (see paragraph 2-3). By cleaning as work progresses the tracking of lead particles into non-contaminated areas and interception of particles before they fall can be accomplished.

Remove dust and debris daily that has fallen on plastic sheets, being careful not to create dust.

Roll debris in plastic and then double bag in six mil (minimum) plastic bags. Place these bags in contractor furnished disposal drums.

Contractor will pay for disposal of all bagged toxic materials and debris in accordance with applicable Federal and State regulations in a licensed land fill and submit receipts for each load to Contracting Officer's Representative.

CLEAN UP AND TESTING

After Completion of Paint Removal and Re-painting, clean all surfaces:

Collect and Double Bag all remaining debris in six mil. polyethylene plastic bags.

Clean All Surfaces including windowsills and paving using high-efficiency particulate air filter vacuums (HEPA vacs), followed by wet washing with high phosphate cleaning mixture (see paragraph 2-3). Removal of Plastic Coverings by Contractor may be done only after final inspection by National Park Service. Perform TCLP test on windows and doors that contained lead prior to the removal.
