RECOMMENDATION(S):

APPROVE and AUTHORIZE the County Administrator, or designee, to execute a change order to increase the payment limit by $1.4 million dollars, to a new payment limit of $64,738,551 with Webcor Construction L.P., a Delaware Limited Partnership, to cover the increased cost from design changes requested by the departments who will occupy the new building at 1026 Escobar Street, and final costs of the relocation of the emergency responder network antennas previously mounted on the demolished tower.

FISCAL IMPACT:

The Board of Supervisors approved a total project budget of $75 million. This action does not increase the total project budget, it simply reallocates $1.2 miilion of contingency funding included in the total project budget to the construction contract. It also moves $0.2 million from the Antenna Relocation Project, approved by the Board of Supervisors with a total project budget of $15 million, to the construction contract for the building of the new antenna site and tower needed to relocate the emergency antenna from the 651 Pine Street tower to the new site on East Bay Regional Parks land in Martinez.

BACKGROUND:

This change order is necessary to cover increased costs associated with two aspects of the project. The first aspect is the final costs associated with building a new antenna site and tower to relocate the emergency radio antenna that was on the 651 Pine Street tower. That antenna is used by police, fire and other first responders through out the county and is a necessary part of the emergency response system. The only site that could be used to relocate the antenna had to be sited on an undeveloped piece of land in the hills owned by East Bay Regional Parks. We ultimately had to build a new road and tower to relocate the emergency antenna. The second aspect is that as we developed the design of the building and worked with the departments that are going to move into the new building, additional features and needs were identified. These additional costs are typical of a design-build procurement method and are why the total project budget includes contingency funds to be used as needed.

CONSEQUENCE OF NEGATIVE ACTION:

Not approving the action would leave the County departments without the design features they need to perform their missions in the new building.
