We intend to bid this contract as a prime contractor and have the following question on the above referenced project:

Under Section 10-1.22 (Building Demolition), Contractor Qualifications (Special Provisions pp. 104) it states that the contractor shall have at the time of Contract Award and for the duration of the contract, a valid, current C-21 License...

Would a current A-1 license suffice (as it covers all categories of construction).

Furthermore if we hire a sub-contractor who has a valid C-21 license to perform demolition, would that meet the requirement of this contract.

Our undestanding is that the reason for this requirement is that the State wants to have a licensed demoltion contractor to perform the "demolition" part of this contract. We believe that either having a higher category license (A1) or having a C-21 licensed sub-contractor performing the demolition work on this contract meets the requirements of the specifications.

Please clarify at your earliest.

"Attention is directed to Addendum #1"


We would like to make arrangements to inspect the Building 213.Can an appointment be made at your earliest convenience?

Contractors will be allowed to inspect Building 213 on Tuesday, May 21, 2002 at 1.00 p.m. Contractors are advised to be at Building 213 at 1.00 p.m. Thereon we shall escort them to inspect the Building 213.

Directions: On Westbound 80, take the YBI exit on left hand side of the upper deck of the San Francisco Oakland Bay Bridge(SFOBB). Follow signs to the U.S Coast Guard Station(USCG) at the end of the Macalla Road - on the far eastern end of the Yerba Buena Island. Building 213 is located just before the main gate to the USCG station on the right side of Macalla Road. On east bound 80, the exit for YBI is on the left hand side of the lower deck of the SFOBB.


Part of the above referenced contract includes demolition of the Yerba Buena Island Fire Station, building 213 (Bid Item 27). In order to prepare a responsive bid for this work, it will be necessary to observe the actual existing conditions with respect to this structure. How can arrangements be made to view the structure? Is the area available for inspection any time? Must there be an escort to the site? Are you going to conduct a formal site tour? If so, when is it scheduled?

See Response to Inquiry #2.


We previously requested access inside Building 213 so that a complete estimate of material inside the structure could be made. Shortly thereafter, Addendum No. 1 was issued stating abatement work under Contract No. 04-A1543 prevented access into the building until June 24, 2002. The abatement contractor informed us that their work would be complete either Friday, May 17 or Monday, May 20. Is it possible to delay the bid opening a few days and arrange for access into the building since the abatement contract is completing?

See Response to Inquiry #2. The bid opening date will not be delayed.


We are requesting that Building 213 be made available for a site inspection prior to the bid opening. In order to prepare a responsive bid for the demolition of the existing structure, a thorough interior inspection of the building and its contents will be required.

See Response to Inquiry#2.
