PART 1 – GENERAL

ITEM 1 - DESCRIPTION OF WORK

1.1 Background: Wilson’s Creek National Battlefield is a civil war battlefield located in SW Missouri.

The main Visitor Center is composed of two sides the Visitor Center side and the Library Addition with a adjoining vestibule in between. The Visitor Center side was built in 1982 and is mainly composed of preformed concrete walls and roof, with a TPO style roof covering. The Library

Addition and Vestibule were built in 2002 and is also composed of preformed concrete walls and a steel pan roof deck, with TPO style roof.

1.2 Work Covered by the Contract Documents:

A. Project Location: The Visitor Center and Library Addition is located at 6424 West Fr 182, Republic, Missouri 65738 in Greene County. (See Exhibit C)

Work consists of: This project will replace a 20-year-old, approximately 8,760 square feet, of failing TPO roof system on Library Addition and Vestibule. Repair 16 penetrations, remove and filled from the deck up including insulation. The new TPO 60 mil will be mechanically attached with 3/8” underlayment over the existing Library and vestibule roofs. The TPO will be extended over the parapet walls on the Library with a new flashing cap to protect the top of the walls. Install approximately 700 LF of flashing on all parapet walls on the Library and Visitor Center roofs.

Also repair all existing externally exposed cracks in exterior walls of the Library, vestibule and

Visitor Center that are larger than 1/8 inch in width. They will be cleaned of excess and loose debris, and filled with Quikrete Concrete Repair (See Exhibit D) or similar product approved by the COR. Estimate 32 hours of labor and $1000 of sealant material to accomplish this task. After all cracks have been sealed in the exterior walls of will be sealed with a concrete sealer.

It is the intent of the park to keep this building open during construction and must always remain weathertight at all times.

Provide labor, equipment, and materials to remove and fill 16 existing roof penetrations, (See

Exhibit B) replace approximately 8,760 square feet of existing TPO style roofing, (See Exhibit A) install approximately 700 LF of new flashing (See Exhibit E) and seal approximately 9483 square feet of concrete walls. The existing roof over the Library Addition has 16 roof penetrations (See

Exhibit B) that will be filled to decrease the likelihood of roof leaks in sensitive areas and will also improve the integrity of the building envelope. These covers, sky lights, and vents will be removed and any penetrating bracing extending above the steel deck will be removed and brought down to deck level, a 18 gauge steel patch will be installed to the existing steel deck to insure a stable platform, insulation will be installed to match existing surrounding insulation board and a waterproof barrier TPO patch will be installed over the existing hole and adhered to existing

TPO roof. Contractor will only be responsible for removing what portions of the penetrations that is above the steel deck. Contractor will coordinate with the COR to schedule with the NPS who will remove any connections from the steel deck down into the building and remaining utilities below the steel deck. Once all penetrations have been filled and sealed, approximately 8,760

Page | 4 square feet of new 3/8” Securoc gypsum-fiber roof board substrate will be fastened through the existing TPO roof to the metal deck using manufactured recommended fasteners and pattern.

Once the new substrate has been installed, a new 60 mil mechanically fastened TPO style roof will be laid over the entire Library Addition and Vestibule roof surface, according to manufactures specifications. Along the gutter edge there will be a new 24-gauge drip edge installed with

4inches under the TPO roof and two inches down into the gutter with a drip edge. Manufacture specified cover tape or welded TPO patch will be installed back over the drip edge to insure a watertight seal. Along the three other sides of the building that have a parapet style wall, the new

TPO will be extended up over the top of the existing parapet wall and terminated four inches down on the outside of the wall and will be fully adhered to the retaining wall using a manufacture recommended membrane adhesive. The HVAC of the building will need to remain in operation at all times to control temperature and humidity within the building. Contractor will be required to work around existing HVAC ductwork that is currently on the roof. The support feet can be removed for laying the new TPO roofing material, but ductwork must stay connected. If ductwork needs to be temporarily disconnected to install new flashing this will need to be approved and monitored by COR. (See Exhibit A) Any variation from this must be approved by the COR. All remaining roof penetrations that were not removed, will have manufactured recommended flashing installed and sealed according to manufactured specification. Next approximately 700 liner feet of new 24-gauge metal parapet cap will be installed along the upper portion of the concrete wall of the Library and Visitor Center to protect the top of the wall from future damage.

(See Exhibit E) The parapet cap will be factory coated with Kynar style bronze finish or similar product, to match the existing metal flashing on the front of the building. Color to be approved by

COR through submittal process. The parapet cap will extend down four inches or whatever length necessary to completely cover the TPO membrane, on the outside of the parapet wall and be fastened with blind fasteners, so that no screws are shown on the exterior of the building. The parapet cap will extend down four inches on the inner wall totally encapsulating the top of the wall and be screwed to the parapet wall according to manufactured specifications (See Exhibit E) for example photos. On the ends the parapet cap will be molded and secure or preformed end caps will be installed to insure a watertight barrier. If top cap is put on in sections, it will overlap at least

2” on all planes and be sealed with manufactured recommended sealer in between sections. or a similar like product approved by COR. Repair all existing externally exposed cracks in exterior walls of the Library, vestibule and Visitor Center that are larger than 1/8 inch in width. They will be cleaned of excess and loose debris, and filled with Quikrete Concrete Repair (See Exhibit D) or similar product approved by the COR. Finally, seal all exterior exposed concrete walls of the

Library and Visitor Center. which are approximately 9483 square feet of both building’s exterior walls will be sealed with a water based penetrating sealer with low VOC and low sheen to not change the appearance of the walls.
