STATEMENT OF WORK

1. BACKGROUND

The Nashville National Weather Service (NWS) Weather Forecast Office (WFO) located in Old Hickory, Tennessee is in need of the complete removal of the existing roof and the installation of a new standing seam metal roof.

The NWS is a 24-hour, 365-day operation, and is a public safety agency. The existing roofing at Nashville NWS needs immediate replacement. High winds caused by the recent storms have torn away large sections of shingles on the main office building. This damage now compromises the building’s ability to be weather proof. It is recommended that a standing seam metal roof be installed as a replacement on the main office.

This roof will replace the existing composition shingle roof and includes, but is not limited to: removal of existing shingles, felt, existing decking if needed, installation of new decking, felt, flashing and edging, caulking, snow/ice retention products, and standing seam metal roof. The required metal roof panel installation is 16” or equivalent on center seams.

Roof panel color will be similar to existing red metal flashing & selected by the local office staff. All work to be completed in a professional manner according to standard industry practices. Any alteration or deviation from specifications involving additional costs, changes to material, or cosmetic changes will require prior written approval from the National Weather Service. A minimum five-year workmanship warranty and a minimum twenty-year warranty on paint and materials is required as part of the included pricing.

SECTION 01 78 00

CLOSEOUT SUBMITTALS

As-built drawings are the marked-up drawings, maintained by the Contractor on-site, that depict actual conditions and deviations from the contract documents. These deviations and additions may result from coordination required by, but not limited to: contract modifications; official responses to submitted Requests for Information (RFI's); direction from the Government Point of Contact; design that is the responsibility of the Contractor, and differing site conditions. Maintain the as-builts throughout construction as red-lined hard copies on site.

These files serve as the basis for the creation of the record drawings.

1.1.2 Record Drawings

The record drawings are the final compilation of actual conditions reflected in the as-built drawings.

1.2 SOURCE DRAWING FILES

Request the full set of electronic drawings, in the source format, for Record Drawing preparation, after award and at least 30 days prior to required use.

1.2.1 Terms and Conditions

Data contained on these electronic files must not be used for any purpose other than as a convenience in the preparation of construction drawings and data for the referenced project. Any other use or reuse is at the sole risk of the Contractor and without liability or legal exposure to the Government. The Contractor must make no claim and waives to the fullest extent permitted by law, any claim or cause of action of any nature against the Government, its agents or sub consultants that may arise out of or in connection with the use of these electronic files. The Contractor must, to the fullest extent permitted by law, indemnify and hold the Government harmless against all damages, liabilities or costs, including reasonable attorney's fees and defense costs, arising out of or resulting from the use of these electronic files. These electronic CAD drawing files are not construction documents. Differences may exist between the CAD files and the corresponding construction documents. The Government makes no representation regarding the accuracy or completeness of the electronic CAD files, nor does it make representation to the compatibility of these files with the Contractor hardware or software. In the event that a conflict arises between the signed and sealed construction documents prepared by the Government and the furnished Source drawing files, the signed and sealed construction documents govern.

The Contractor is responsible for determining if any conflict exists. Use of these Source Drawing files does not relieve the

Contractor of duty to fully comply with the contract documents, including and without limitation, the need to check, confirm and coordinate the work of all contractors for the project.
