Subject: 2005
Sewer Line Replacement Project
_________________________________________________________________________
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.
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.
