RTC Short Form

July 16, 2002

SUBJECT:

Authorization to Increase Expenditures Under an Existing Contract for Electrical System Improvements at the Water Pollution Control Plant Administration Building (#F0207-01) (RTC#02-281)

REPORT IN BRIEF

Approval is requested to increase expenditures under an existing contract with Koffler Electrical of San Leandro for electrical system improvements at the Water Pollution Control Plant (WPCP) Administration Building for the Department of Public Works Engineering Division (Project #PR-98/10-99).

BACKGROUND

On August 28, 2001, Council awarded a contract to Koffler Electrical for electrical upgrades to the WPCP Administration Building (RTC #01-302). The contract award was in the amount of $62,930 (total bid amount of $57,209 and a contingency of $5,721).

DISCUSSION

Construction costs exceeded the contingency authorized by Council due to design modifications required during the construction phase of the project. The issues were not addressed in the design stage because the available records drawings for the WPCP Administration Building did not show enough detail to allow the City's design consultant to incorporate the changes into the original scope of work. The necessary changes made in the field increased the cost of the project.

Staff requests that the $5,721 contingency be increased to $14,632 to accommodate the changes required during construction.

 

FISCAL IMPACT

Modified project costs include:

Construction - Base Bid

$55,153

Additive Alternate

2,056

Construction Contingency

$14,632

Total cost

Funds for the increased expenditures in the amount of $8,911 are available in Public Works Infrastructure Account 820420 - WPCP Replace Hot Water Loop.

RECOMMENDATION

It is recommended that Council authorize additional expenditures under an existing contract with Koffler Electrical and increase the total contact amount from $62,930 to $71,841.
