General Statement of Work & Project Background

Statement of Work

The contractor is required to provide labor & equipment to remove the existing greenhouse glazing materials and aluminum joint caps, clean & prepare installation frames and then install new polycarbonate glazing materials, reinstall original aluminum caps on seams, and seal all exposed joints with proper sealants for water proofing.

Contractor is also required to properly dispose of the old demolished polycarbonate greenhouse glazing or other materials to be discarded from the project located at the facility listed address above.

Background /Existing Greenhouse Bays

The existing greenhouses were erected in 1996 & the polycarbonate glazing panels are now in a state of disrepair requiring removal and replacement of the main polycarbonate roof panels and the polycarbonate roof vent panels General Information

There are 3 greenhouse bays – each measuring 30 feet wide x 48 feet long.

The main roof panels appear to consist of twin- wall ½” channeled clear Exolite polycarbonate panels which are 4’ wide x 16’ long

The main roof panels on the east side of each greenhouse are 4’ wide x 12’ long with 4’ wide x 4’ long panels comprising the associated roof vent materials > all use the same clear Exolite twin-wall ½” channeled glazing materials.

Actual sizes of the existing products are to be verified by the bidders if at all possible before making submissions and bids. Descriptions and sizes listed above are offered by the government as a general description and should not be used as a verified product size description.

The existing panels were clear when installed and are now opaque from 24 years of UV light exposure & from multiple penetrations from hail and subsequent staining from dirt inside the channels.

The greenhouse bays share interior walls of clear corrugated fiberglass materials – end walls, side vents, & exterior side walls consist of the same Exolite materials as the roofs, but they will not be replaced during the course of this project.

Scope of Work:

The contractor will be required to provide all labor, materials, and equipment to remove and properly dispose of the existing glazing materials and furnish the government point of contact with a copy of the disposal slip from the landfill that the contractor uses following disposal.

Materials:

The same twin-wall ½” Exolite brand clear polycarbonate glazing can be supplied and installed by the contractor unless the contractor can provide a detailed product submittal to the government for approval as an alternative product for acceptance. Multiple polycarbonate products can be submitted to the government to include material specifications and differences in cost based on installed per square foot price. The government requires pre-acceptance of products to be completed before purchase of materials by the contractor and subsequent installation.

The government may schedule a pre-bid meeting in the solicitation for bids to be held at the location listed above for contractors to observe existing conditions, verify dimensions, and specifics of the materials that need to be supplied under this contract. This meeting would be listed in the advertisement for bids.

If desired, potential bidders may also request a site visit coordinated thru the local government point of contact before bidding to help clarify the requirements of this contract if they are unable to attend the scheduled government pre-bid meeting.

Methods for installing the new glazing products are required to follow greenhouse manufacturers guidelines including all facets of moving materials safely to the site, storing, handling, and installing the products, then properly reinstalling the existing extruded aluminum caps that were removed and saved for reuse during the removal portion of the existing glazing, finalized by sealing all exposed joints with certified sealants for exterior glazing installation at all seam locations allowing for expansion and contraction to prevent exterior penetration of water to the interior of the greenhouses. Glazing installation must be properly installed to allow for expansion & contraction of the panels to avoid buckling or cracking of the panels due to temperature related pressure extremes.

Execution of this contract by the successful bidder and its employees must meet the existing guidelines during the contract execution period for safely conducting all work following the newest in force Covid 19 Directives issued by the CDC for non-government construction contractors.

Coronavirus and COVID-19 safe behavioral and work practices Maximum crew size shall be six personnel, including the supervisor.

The Government will not be responsible for providing hand washing stations and will not provide restroom facilities during the course of the project. The contractor has the responsibility for providing their employees hand washing stations or hand sanitizer products as well as porta-potty stations for personal use.
