The scope of work for this project includes:
1. Visual evaluation
2. Preparation of report addressing:
a. Current condition with emphasis on existing internal and external coatings.
b. The presence and thickness of sediment at the bottom of the tank.
c. Evaluation of the condition of the structural components of the storage tank, including any
appurtenances such as ladders, platforms, handrails, vents and overflow piping. Any
safety or variations from OSHA standards shall also be identified.
d. Evaluation of the condition and operation of the insect screens, drain pipes, overflow pipe,
and weir boxes shall also be observed and evaluated. Tank penetrations such as hatches,
vents, and overflows shall be inspected to determine if they pose any threat to the sanitary
conditions of the tank.
e. Summarization of the conditions found.
f. Cost estimates for recommended improvements to each tank on a separate sheet.
3. Prioritization of tanks requiring rehabilitation
It is expected that an Offeror will spend approximately one day at each tank observing and collecting
information for the tank condition assessment. It is up to an Offeror to determine the actual amount
of time needed. A GCWW employee will be assigned to the project to assist the consultant with
coordination and entry to the tanks and tank sites.
An Offeror should be prepared for wet inspection to determine the condition of the interior of
the tanks and the existing coatings using rafts, divers or ROVs. All work shall be performed in
accordance with AWWA C652. GCWW will operate valves to isolate the tank while the inspection is
performed inside the tank.
Deliverables to GCWW shall be packaged in one condition assessment report but is to
include a narrative report detailing the findings at each tank. The report shall also include
photographic evidence and a general discussion of the conditions at each tank. General
recommendations regarding the condition of the tank shall be made.
The summary of the report shall include a ranking of all the tanks to determine which tank
needs to receive corrective action first. A narrative discussion shall accompany the summary
that describes the system used in the ranking process.
An Offeror shall budget for two meetings, each with duration of 2 hours, to be held with an Offeror
and GCWW personnel to discuss the findings. One meeting will be held to review the draft report
and another meeting will be held once the final report is completed.
GCWW will use the condition assessment report as the basis for prioritizing and directing future
capital and maintenance projects. Deadline for written questions 02/02/2024 All questions or requests for clarification must be submitted in writing no later than February 2,
