FPUD approves change order for 1 MG Reservoir re-coating

The Fallbrook Public Utility District approved a change order for the 1 Million Gallon Reservoir re-coating project.

The 5-0 FPUD board vote March 27 approved a change order adding $32,300.15 to the contract while adding the tasks of repairing holes in the roof, repairing the rafters in the center area of the tank, a sweep blast of the exterior roof and shell, and grinding the rafter edges.

"It was just to address some structural issues," said FPUD assistant general manager Jack Bebee.

In 2012 FPUD developed a 10-year program to re-coat all 11 of the district's steel reservoirs to ensure continued service life and avoid more costly replacements. A dive inspection of all tanks identified those which required immediate action to protect the steel from structural damage due to the deterioration of the pumping system.

In November 2016, FPUD's board voted 5-0 to award Simpson Sandblasting a $332,285 contract, which matched the company's bid, to re-coat the 1 Million Gallon Reservoir in DeLuz. The work began in early 2017.

On Jan. 30, FPUD general manager Brian Brady approved a change order for $21,578.30 to complete interior repairs to protect the tank's structural integrity. The additional repairs authorized March 27 are necessary to ensure the long-term reliability of the coating and to prevent future corrosion.

"The change order was for some additional structural repairs on the metal tank," Brady said.

The holes in the tank roof will be repaired by welding a plate over the holes; that work will add $1,712.94 and one calendar day to the contract. The replacement of an additional 80 feet of damaged or corroded rafters at the center column of the tank will increase the contract by $24,900 while extending the work time by seven calendar days.

A sweep blast of the exterior roof and shell will remove corrosion and loose paint and will add $3,887,21 and one calendar day to the agreement. Grinding the rafter edges will create a smooth and square edge for coating and has a cost of $1,800 and a timeframe of one calendar day.

The January change order extended the completion date from June 18 to June 30, and the new change order moves the completion date to July 10.
