The city added another $450,000 to the contract with the general contractor for the ultraviolet disinfection system at the filtration plant as related to the chlorine leaks that occurred in November 2016.
The Board of Estimate and Contract approved the ninth change order for the contract with C.O. Falter Construction at this morning’s meeting.
The new work is for removal of systems for shipping for repairs, testing the repaired systems, re-installing them and providing spare parts. There will also be replacement of control panels on site, with related testing and spare parts.
The change adds $454,314.77 to the contract. It brings the contract to a total of $7,281,667.38.
Since the leaks, the city has added $498,781 to this contract in several amendments.
The federally mandated UV system was to go online November 2016, but two chlorine leaks in that new building as it was being incorporated into the overall filtration system shut the building down.
An investigation into the cause and the subsequent repairs delayed the project.
The city then received another extension of the federal deadline, until the end of May 2019.
