CITY COUNCIL AGENDA ITEM NO. 7
Meeting Date: April 22, 2003
Subject/Title: Authorize the City Manager to execute a Change Order with Harris and Associates for additional services for Brentwood Boulevard Widening, CIP Project No. 336-3054
Submitted by: Engineering: B. Grewal/E. Kim
Approved by: John Stevenson, City Manager
On September 24, 2002, the City Council authorized the award of the Construction Contract to Top Grade Construction, Inc.
On October 8, 2002, the City Council authorized the City Manager to execute a Change Order with Harris and Associates in the amount of $108,200.00 to provide inspection and materials testing services during construction.
The original contract with Harris and Associates provided for design and project management services scheduled to be completed by December 31, 2001. The schedule and scope of engineering services required have substantially increased as the project has progressed due to unforeseeable circumstances. The attached proposal from Harris and Associates provides for the increased level of efforts associated with the extended schedule and expanded scope of services that have been identified by staff as necessary for the proper completion of this project.
The original design schedule was extended approximately ten months due to right-of-way acquisition and procedural issues with Caltrans. Additional design and project management costs were incurred and are mainly due to the extended design schedule, design modifications directed by staff during the final design stages, and the scope of surveying required. The original design was modified to incorporate traffic signal modifications at the Sand Creek intersection, installation of City standard fiber optic conduit, layout changes for improved safety and access, survey staking of utilities to be relocated by utility companies, additional construction staking, the addition of improvements relative to the Gregory Ranch Development (to be reimbursed by the Developer), revisions to specifications after final documents were complete (due to changes in State and Federal requirements), the design of revised planting and irrigation plans, the addition of trees (a plan that has since been dropped due to the State pulling back funds for the added trees.) This added work was not included in the original scope for Harris and Associates and could not have been anticipated in July of 2000, when the original Agreement was executed.
The increased costs for construction services are mainly due to maintenance of construction services through an extended construction schedule. Construction was originally anticipated to be substantially complete by the end of March. Currently, the project is expected to be substantially complete by the end of June, a three month delay. The main factors contributing to the schedule extension are modification of the construction phasing and weather delays associated with construction during the winter. The City imposed specific construction phasing to provide for continuous pedestrian and bicycle access along Brentwood Boulevard throughout construction by limiting the area of work. The construction phasing consisted of postponing all construction activity on the west side of Brentwood Boulevard between Sand Creek Road and Village Drive, where a pedestrian/bicycle path was located, until new curb, gutter, and sidewalk was constructed on the east side of Brentwood Boulevard to serve as an alternate route. The pedestrian/bicycle path was the only means for pedestrian and bicyclists to travel safely along this section of Brentwood Boulevard and no alternate route was available due to Sand Creek Road construction, so staff prohibited any disruption to this path until the east side sidewalk was completed. This schedule phasing resulted in a schedule increase of approximately two months. Additionally, inclement weather has resulted in numerous partial and non-work days, which have added another month to the construction schedule. Staff highly recommends maintaining the current level of construction inspection and materials testing services through project completion to ensure that the grant funding requirements are met.
