SECTION 011000 - SUMMARY

PART 1 - GENERAL

1.1 PROJECT INFORMATION

A. Project Identification: Trout Creek Main Office Roof Replacement.

1. Project Location:

a. Trout Creek Ranger Station

2693 MT HWY 200

Trout Creek, MT 59874

B. Owner: USDA Forest Service, Kootenai National Forest.

C. The work consists of removing the existing asphalt shingled roof and all underlayment materials, replacing damaged roof decking, and installing a complete asphalt shingle roofing system. The work also includes the removal of the existing rain gutters, fascia and soffits, replacing damaged or improperly installed sub fascia, installing new metal facia, installing new metal soffits, and installing new gutters and downs spouts. All work will be performed on the main office located at the Trout Creek Ranger Station.

D. Work by Owner:

1. The Forest Service will conduct testing of the existing roofing materials for the presence of asbestos prior to the commencement of work under this contract. A complete report will be furnished to the contractor.

E. Work Under Separate Contracts:

1. None.

F. Owner-Furnished Products: The following products will be furnished by Owner and shall be installed by Contractor as part of the Work:

1. None.

A. G. Submittals:

1. The contractor shall submit the following along with the price quote:

a. Safety Plan, including a Fall Protection Plan

2. The contractor shall submit the following at the prework meeting:

a. A proposed day by day work schedule.

b. A list of all subcontractors, and their intended use.

c. Materials list and color options for all components of the roofing system that require a color choice (Shingles, Fascia, and Gutters).

d. Materials selected for each layer of the roofing system.

e. Description of flashing materials.

f. List of sealants to be used on the project.

3. The contractor shall submit the following at end of the project, before the final payment:

a. Manufacturer’s Warranty as described in Section 07311, Part 1.1 – C.

H. Building Details and Work Items:

1. Remove existing gutters and downspouts. Gutters will not be reused on this project.

2. Remove all existing roofing materials down to the roof sheathing.

3. Remove existing fascia and trim boards.

4. Install new sub-fascia where water damage is present, or the existing materials have been improperly installed. It appears that some of the sub-fascia may have been installed too high, creating an area that allows water to sit at the drip edge. The existing sub-fascia is made of a timber-strand material (like oriented strand board - OSB), replacement can be the same or structural select DFL framing material.

5. Remove and Replace any damaged roof decking. Existing decking is made from 5/8” OSB, new boards should match existing. Notify the Contracting Officer prior to exposure of the roof deck for inspection and concurrence on what roof decking needs to be replaced.

6. Install metal fascia. Metal should be formed to completely cover all exposed surfaces of the sub-fascia. Provide a profile with stiffening beads to minimize oil canning of the fascia material.

7. Place ice and water shield as shown on the drawings. Use synthetic underlayment for the rest of the roof deck.

8. Ridge: ensure decking and underlayment allow for a vented ridge as indicated by the shingle manufacturer’s instructions.

9. Install asphalt roofing shingles according to the specs and manufacturer’s installation instructions. Use appropriate starter strips, flashings, sealants and vented ridge system to meet warranty requirements.

10. Furnish and install permanent fall protection anchor points at the ridge at locations shown on the drawings. Provide OSHA approved fall protection anchors designed to be permanently installed under the ridge of a shingled roof.

11. Furnish and Install new seamless rain gutters. Tie rain gutter down-spouts into existing drainpipes where available.
