c. The Contractor is responsible for visiting the site prior to submitting a bid to observe existing conditions. No compensation will be provided for conditions that would be visible during an on-site visit for persons experienced performing this type of work.

3.1 Bid Schedule:

3.2 Description of Work:

a. The project is to demolish and dispose of Greenhouses 16 in its entirety. The greenhouse is approximately 650 SF.

The Greenhouse has a dirt floor with a concrete walkway running through the middle. Demolition shall include removing the building, concrete foundations, walkway, water supply, and electrical service back to the panel and all appurtenances related or connected thereto. Removed utilities shall be terminated in a manner conforming to the nationally recognized code covering the specific utility and approved by the COR.

b. During demolition, provide safeguards, including warning signs, barricades, temporary fences, and other similar items that are required for protection of all personnel during demolition and removal operations. Maintain fences, barricades, and other similar items around exposed excavations until such excavations have been completely filled.

c. This Greenhouse was built in 1984. No asbestos survey is available for this building. Due to the year and type of construction, asbestos containing materials are not expected to be encountered. Base bid amount should reflect this assumption. Contractor shall inspect the site and building and complete a hazardous materials assessment before the demolition starts. The cost of this assessment shall be included in the Contractor’s base bid. If ACM or other hazardous materials are found, it will be immediately brought to the attention of the CO and COR for resolution which will be through a contract modification.

d. The Contractor shall be responsible to handle and dispose of debris at an off-site, certified disposal site consistent with all Local, State, and Federal requirements.

e. After demolition, holes shall be filled and disturbed areas shall be leveled with friable topsoil which shall be placed and spread to the height of the surrounding area and seeded with grass seed mixture to match surrounding vegetation and covered using a straw mulch to prevent erosion until growth and coverage is achieved. On completion of work, leave site in clean condition.

f. All contents, furniture, appliances, equipment, material and debris shall be removed and disposed of by the contractor.

g. Contractor shall perform a metal sweep of the restored demolition site and the roads used to haul the demolished material offsite.
