SUBJECT:

Accessibility Improvements 2^nd, 3^rd, 4^th, and 5^th Floor Toilet Rooms at 455 County Center, Redwood City, CA 94063

RECOMMENDATION:

Resolution authorizing the Director of Public Works to execute contract revision orders in addition to the previously authorized contract revision orders, with the understanding that the contract revision orders authorized by this resolution shall not exceed $33,882 in total, for an aggregate authority in an amount not to exceed $69,402.

VISION ALIGNMENT:

Commitment: Ensure basic health and safety for all.

Goal 7: Maintain and enhance the public safety of all residents and visitors.

Your Board’s adoption of the proposed resolution will result in a safer, environmentally sound project by mitigating asbestos issues while completing the project.

BACKGROUND:

The Board of Supervisors adopted Resolution No. 069851 on December 16, 2008, authorizing execution of a Contract with Rockaway Construction Inc., for the Accessibility Improvements, 2^nd, 3^rd, 4^th and 5^th Floor Toilet Rooms Project, to provide for ADA accessibility. The Director of Public Works was also authorized to execute contract revision orders related to the Project not exceeding $35,520 in aggregate.

DISCUSSION:

The project began on schedule on February 20, 2009 with demolition work. Hazardous asbestos-containing materials, which were previously hidden, were found in the mastic under several layers of flooring, as well as in the insulation of hot and cold water pipes within the walls’ cavities.

These findings were substantiated by an independent consultant report. The presence of hazardous materials had not been detected in previous surveys, and its removal had not been anticipated in the project’s cost estimate nor included in the bidding process.

The removal of hazardous materials from the site became imperative in order for work to proceed safely and the schedule maintained. The authorized contract revision order amount of $35,520 was utilized to subcontract the services of an abatement contractor for the removal of these materials.

The cost of this work, ($33,882) consumed nearly the entire authorized revision orders amount (of $35,520), which was intended to cover normal construction changes that are typical in remodels of existing facilities. Therefore the increase in authorization for the Public Works Director is needed to address the normal construction changes that may occur.

 If this additional authority is delegated, the Director’s revised aggregate authority would be increased to $69,402.

FISCAL IMPACT:

The total maximum contract amount is revised from its original base amount of $236,800 to include the abatement cost of $33,882, as well as the revision order amount of $35,520 (15% of the base contract) for a new grand total authorization not to exceed $306,202. This project is included in the 2008-2009 Capital Projects Budget and is financed by Facility surcharges.
