1.3 STATEMENT OF BID ITEM(S)

The scope of this project includes emergency roofing replacement on 8 existing buildings. These roofs consist of five buildings with flat roofs using a TPO membrane for a new roof, two buildings that will replace existing slate tile, and one building with an asphalt shingle roof replacement as described and shown on the drawings. The buildings included as part of this effort include:

BUILDING #1

The original building was designed and constructed circa 1931-1933.The scope of work consists of replacing the existing upper roof located over the elevator penthouse and replace three (3) existing roof drains, replacing the roofing on a narrow area surrounding the base of the penthouse tower, and replacing the roof over an outdoor patio area located on the 4th floor. In addition, the existing wood balustrade surrounding the perimeter of the upper penthouse roof will be repaired and reconstructed to match the original historic design. Existing antenna and telecom equipment mounted on the upper penthouse roof level

01 00 00 -2 will need to remain in place and the contractor will be responsible for removing the existing roof assembly and install the new roof assembly without disturbing this equipment. The total area of work is approximately 2,633 SF for the three (3) roof areas.

BUILDING #4

The original building was designed and constructed circa 1931-1933 with a subsequent addition in 1936-38 on the southwest and a later ground floor addition (date unknown) was constructed on the northwest side.

The scope of work consists of replacing the existing roof located over six (6) existing flat roofs areas at different levels above the ground elevation on the north, south, and west sides of the building. The existing wood balustrade surrounding the perimeter of the north and south roof areas will be repaired and reconstructed to match the original historic design. The total area of work is approximately 3,565

SF for the combined roof areas.

BUILDING #5

The original building was designed and constructed circa 1931-1933.The scope of work includes replacement of two walkable flat roof porch covers with railings facia, ceilings, trim, and columns to be replaced.

Painting the faces of 7 dormers and a entry porch is included. The existing decks will be removed along with supports columns. The non-rotted columns will be salvaged for reuse. The porches will then be rebuilt to match the existing historic original size and character. New structural columns to match the existing Doric architectural style columns will be added. The new porch will be sloped ¼ inch per foot to improve drainage from the deck. New perimeter copper gutters will be installed with an additional downspout. The new deck will have an

80mil. TPO roofing installed with walking pads for durability. The existing railing will be constructed and a guard rail at the top of the perimeter railing will be added for code and safety compliance. The lightning protection system will then be replaced with new conductor cabling and air terminals. New lighting will be reinstalled under the underside of the porch.

BUILDING #12

The original building was designed and constructed circa 1931-1933. The scope of work consists of replacing the existing slate roof and reconstructing deteriorated eaves, gutters, and downspout roof drainage system. The roof on this building is a pitched gable form with a slope of 7/12. The existing wood deck at the eave overhangs with exposed rafter tails and copper gutter will be repaired to match the original historic design. Additional downspouts will be located to improve the flow of roof storm water discharge collected by the gutters. The total area of work is approximately 5,760 SF.

A warehouse addition (date unknown) was constructed on the south side of the original building, and metal canopies were constructed on the

01 00 00 -3 north side of the original building circa 2009. These metal roof areas are not in the scope of work for this project.

BUILDING #17

The original building was designed and constructed circa 1931-1933. The scope of work consists of replacing the existing slate roof and reconstructing deteriorated eaves, gutters, and downspout roof drainage system. The roof on this building is a pitched gable form with a slope of 7/12. The existing wood deck at the eave overhangs with exposed rafter tails and copper gutter will be repaired to match the original historic design. Additional downspouts will be located to improve the flow of roof storm water discharge collected by the gutters. The total area of work is approximately 6,466 SF.

A warehouse addition (date unknown) was constructed on the south side of the original building, and metal canopies were constructed on the north side of the original building circa 2009. These metal roof areas are not in the scope of work for this project.

BUILDING #18

The scope of work will replace the existing flat “L” shaped roof totaling 6,850 SF. The original “Laundry Services” facility was designed and constructed circa 1933 with two subsequent additions added to the facility in 1959 and again in 1985 on the north and northwest side. The scope of work consists of replacing the existing roof located over two (2) existing flat roofs areas at different levels above the ground elevation on the north, and west sides of the building. The west flat roof has a concrete deck, and the north flat roof has a metal deck. Both roofs will require tapered poly-iso insulation slopped at ¼ inch per foot for water to drain off the building. The north roof has two internal drains and the west roof drains into gutters on the roof edge. The new roof is to be an 80 mil TPO system with some walking pads for mechanical equipment to be serviced located on the roof. The total area of work for these two flat roofs is approximately 3,190 SF for the combined roof areas. In addition to the flat roof work, some rotten wood replacement has been identified to be repaired on the sloped roof.

These areas incudes the fascia on the gabled ends and about 100 square feet of wood deck under the imitation slate roofs. This imitation slate has been identified as Eco-Star product.

BUILDING #61

This facility is a hipped asphalt shingle roof which is to be replaced totaling 60,000 SF. The original facility was constructed between 1974

-1975 with a flat roof. This facility was retrofitted in 1993 from a flat roof facility to a sloped roof with asphalt shingles. The building has since received two additions, one in 1994 and a second in 2009 with similar sloped asphalt shingle roofs. It is estimated that 25% - 30% of the plywood sheathing is sagging between the pre-engineered wood joist due to improper ventilation of the attic. This project proposes to

01 00 00 -4 replace the sagging decking, with new structural grade ½: plywood decking to match existing thickness. The attic will be properly insulate the attic with R-38, 12 inch thick, batt insulation, to ASHRAE

90.1 standards for zone 3A. New underlayment will be provided with flashing ridge vents and architectural grade asphalt shingles. The lightning protection system will then be replaced with new conductor cabling and air terminals. New lighting will be reinstalled under the underside of the porch. Lastly, several of the roof hatches will be repaired as they were found to not be accessible due to the original poor installation.

BUILDING #135

The original building was designed and constructed circa 1983-1987 and the building is a non-contributing resource within the historic district. The scope of work consists of replacing the existing roof located over multiple existing flat roofs areas at different levels above the ground elevation on the north and south sides of the building. The existing skylights on the south roof area will remain in place with new roof curb flashing installed at the existing skylight curbs. An existing exhaust system located on the northwest roof area at the second-floor level will be removed and temporarily stored on site during installation of the new roof system in this area. The contractor will be required to reinstall this existing exhaust system equipment back to working service condition after the new roofing work is complete. The VA will need to provide temporary accommodations for the space served by this unit while the exhaust system is temporarily out of service. The total area of work is approximately 17,400 SF for the combined roof areas.

ALTERNATE NO.1: BASE BID except delete all work associated with the

Reroof of Building 18 and Building 4.

ALTERNATE NO.2: ALTERNATE 2 except delete all work associated with the

Reroof of Building 12 and Building 17.
