From The Montrose Press (Andrew Kiser):
City Council voted unanimously Tuesday for $87,000 to Farnsworth Group for out-of-scope design services associated with the Sunset Mesa Tank Replacement project.
The below-ground water storage tank on Sunset Mesa has been around the 1960s. The storage was nearing the end of its usage as structural damage has caused the need for a new tank, located next to the Sunset Mesa Sports Complex baseball fields…
Throughout this design effort, numerous out-of-scope items were required for the completion of the project.
In the city council packet, the Farnsworth Group provided detailed information into what changes needed to occur for the water tank project.
The company listed more evaluations and extras services for increased interconnectivity, operational flexibility, operator access and safety needed to be included.
The structure also needed easier access in locating interconnecting piping in the lower level of pump station as that will provide more convenient expansion in the future and safer access for operations staff.
The design will also help staff as it’ll provide a mounted valve actuator system and housing which will be safer and more convenient access. This will require increases in building size and electrical and instrumentation system designs.
It will also complete several design iterations to efficiently connect inlets, outlets and drains of the proposed and future standpipes; as well as additional pumps and drains.
The Farnsworth Group also suggested the project should have designs for potential future additions of disinfection residual control system and forced air ventilation system for THM removal.
The company said the water tank should have added flow metering for both inflow and outflow pipes. Control descriptions should be prepared for the operation of the pumps and the standpipe inflow valve and valving operations, Farnsworth Group wrote.
Finally, the Farnsworth Group determined a splitting project into two separate bid packages while adding contractor coordinator requirements. The intent is to stay away from the general contractor price markup on the tank portion of the project.
