Subject: Contract Change Order No. 1 — Big Ben Engineering for Old Town Emergency Sewer Repairs
The Public Works Department is requesting the approval of Contract Change Order (CCO) No. 1 with Big Ben Engineering. On March 19, 2024, the City Council awarded a Public Works Agreement to Big Ben Engineering in the amount of $135,000 to complete emergency sewer repairs in Old Town. The City Council also authorized the City Administrator to approve contract change orders up to 10% of the contract not -to -exceed amount, or $13,500. CCO No. 1 is for $13,500 or 10% of the construction contract amount, and within the City Administrator's administrative approval limit.
CCO No. 1 included the removal and replacement of the entire existing sanitary sewer manhole structure located on Camarillo street. The original scope included the reconstruction of the existing manhole structure bottom.
During a pre -construction field visit between the contractor and public works staff, additional deterioration was discovered extending along the walls of the existing manhole, not only along the manhole bottom as originally identified. Since the structural integrity of the manhole was compromised the contractor became concerned that removing the manhole base may lead to complete failure of the entire manhole. This failure would risk the safety of the work crew and potentially damage the connecting line and surrounding infrastructure and drastically increase the scope of the project. After discussion this concern was also repeated by public works staff.
Replacement of the entire manhole would also increase the design life of the sewer line and reduce the possibility of wastewater backups. For these reasons staff recommends approval of CCO No. 1.
The various elements comprising CCO No. 1 are summarized in Exhibit "A" attached to the CCO form. CCO No. 1 will result in a net construction contract amount of $148,500. There is sufficient funding in the remaining project budget to cover the cost of the additional work.
