H. SCOPE OF SERVICES
A. Tank Evaluation
Field Inspection
The field evaluation will include the inspection of the interior and exterior of the tank b)
technicians to identify sanitary, safety and structural deficiencies. The tank interior wil
be pressure washed to remove all sludge and sediment. Measurements of tanl
accessories, metal loss, ultrasonic steel thickness, coating adhesion, and coating thicknes:
will be taken. Structural deficiencies will be noted and the existing coating will IN
evaluated. The exposed portions of the foundation will be visually evaluated to locat(
cracks, spalling and other types of deterioration. Field data collected will be reviewed b)
a structural engineer to determine the integrity of the tank. Coating samples will be taker
and adhesion tests performed to determine recommendations for painting an(
rehabilitation. The cathodic protection system of the tank will be visually inspected. B;
reviewing corrosion patterns and metal loss, the apparent working order of a cathodi■
protection system will be determined.
Prior to inspection,the City will:
1. Isolate the tank from the system and completely drain the tank.
2. Opening of all manholes for tank access.
3. Disinfect and bacteriologically clear the tank following inspection.
Coating Evaluation
Coating samples will be taken during the field inspection and tested to determine thei
lead, chromium, and cadmium content. The coating thickness and adhesion tests will bi
done to determine the present condition of the interior and exterior coatings. Based of
the test results, the existing condition of the tank surface will determine the amount o
surface preparation required for painting of the tank.
Structural Evaluation
The field evaluation will identify any observed structural deficiencies or damage that may
have occurred since the tank was constructed. Any deficiencies found will be analyzed
for their affect on the structural integrity of the tank.
Evaluation Report
An evaluation report will be provided for the tank and include the following:
1) Observation: The observation section of the report will provide dimensions of the
tank and accessories, as well as a narrative description of the condition of each
part of the tank. Safety and structural deficiencies observed will be described and
an assessment of the coating condition.
2) Recommendation: The recommendations section of the report will include repairs
and modifications required to bring the tank into compliance with present
AWWA D100, D102 and Manual M42 and OSHA safety standards. Coating
recommendations will be made. When practical, alternative methods of repair,
modification,and painting will be provided.
3) Economic Factors: The economic factors section of the report provides budget
estimates for all of the repairs, modifications, and coating requirements outlined
in the recommendations section of the report.
4) Photographs: The report will contain color photographs of the tank. The
photographs serve as additional documentation of the tank's condition.
5) Summary Report: Prepare a summary report presenting the findings, conclusions,
and recommendations resulting from the tasks above. The report will be certified
by a professional engineer.
B. Final Design
Final design will result in preparation of the bidding and contract documents,engineering
drawings and technical specifications for the recommended repairs and coating of the
Eastern Service Area Elevated Water Storage Tank. The final design documents will be
submitted to the City for review at the 90-percent completion level. A review meeting
will be held with the City following the 90-percent submission. Three (3) sets of
documents will be provided to the City at the 90-percent and final submittals. Tasks to
be completed during this phase are summarized below:
1) Prepare a comprehensive project manual that contains bidding and contractual
documents (Divisions 0 and 1) and technical specifications for competitive
bidding (Divisions 2 through 16). The project manual and its contents will be
formatted in accordance with the Construction Specification Institute(CSI).
2) Drawings or details, if any, to further define existing conditions,
modifications/repairs and requirements of the project.
3) Final Opinion of project cost to be submitted with the 90-percent submittal.

performed once per week, unless otherwise required. The inspector will maintain
a log of written inspection reports. Based on the current inspection reports
previously performed, it is anticipated that two (2) inspections will be required of
the repair work performed.
2) Tank Coating: Inspection during surface preparation and coating operation will
be provided by a NACE "trained" inspector to assure conformance of the work
with the coating requirements of the contract. Inspections will be performed at
the following construction progress milestones:
Inspection No. Milestone
1. Beginning of Abrasive Blast and Surface Preparation
