Subject:          2005 Sewer Line Replacement Project

        _________________________________________________________________________

 

RECOMMENDATION

 

It is recommended the Board of Directors authorize the general manager to execute an increase of $20,700 in the construction contract for the 2005 Sewer Line Replacement Project resulting in a revised contract amount of $546,950.

 

SUMMARY OF ISSUES

 

Proposed change order number 1 is attached and will increase the contract sum by $20,700 for additional work performed by the contractor, D’Arcy and Harty Construction, Inc. on the 2005 Sewer Line Replacement Project.  The bid form in the construction documents included a line item for reconnecting 30 house laterals along 3,450 feet of new sewer main lines included in the base bid for a unit price of $1,100 per connection, with the understanding the contractor would be compensated for the actual number of connections completed in the field.  Four optional bid items for the installation of an additional 2,050 feet of sewer main line were included in the contract award, but the number of house laterals in the bid form was not increased. 

 

The proposed change order includes 22 additional lateral reconnections at the unit cost of $1,100 and a credit of $3,500 for a manhole that was not required resulting in a net increase of $20,700 in the contract sum to $546,950.  District staff and the project engineer have confirmed that a total of 52 sewer laterals were reconnected in the field and suggest the change order be approved. 

 

District policy, adopted by Resolution 01-23, allows the General Manager to approve change orders within a limit of 5% of the contract amount or $15,000, whichever is less.  The proposed increase represents 4% of the original contract value of $526,250.  There are adequate funds available in the allocation of $650,000 included in the District budget for this project.     

 

PROJECT  STATUS

 

D’Arcy and Harty Construction has achieved substantial completion on the project completing installation of 800 feet of sewer lines on an easement between Cypress Drive and Palmero Way, 1150 feet on Sunridge Road between Chamisal Way and Costanilla Way and 700 feet on Mestres Drive.  Remaining punch list items will be completed within several weeks. 

 

The contractor submitted an initial pay request for 80 % of the $526,250 construction contract.  E2 Consulting Engineers has earned $45,920 of the budget of $89,260 for design and construction support engineering services.
