PHASE I WORK - Detailed Inspection

This field portion will require that each tank be completely drained and taken out-of-service for at least two (2) working days. Since our inspection will concentrate on critical load-bearing structural members, it is mandatory that the interior of each tank be cleaned and thoroughly washed out prior to our scheduled inspection. This cleanout can be performed by OWNER personnel or, as an addition to our inspection contract, we can perform the cleaning with our own forces.

The PHASE I field work will consist of the following:

A. An extensive visual inspection of all critical plate members, primarily stressed welds, roof structural work, tower support members, anchorage, appurtenances, etc.
B. Ultrasonic measurement of plate thickness and pitting at all suspect or highly corroded surfaces.
C. Check of the entire structure for compliance with OSHA regulations.
D. Visual examination of the tank foundation and electrical components.
E. Visual examination, generic identification, destructive and nondestructive
testing, and any other tests required to establish the condition and performance of the interior and exterior coating systems.
F. Laboratory analysis of heavy metal content (ASTM-D3335 and TCLP, if required) of the existing paint.
G. If indicated, perform test applications of alternative methods of paint removal.
H. Verification or measurement of tank dimensions, tower member sizes and all appurtenances.
J. Site dimensions and any other conditions which may affect the future
rehabilitation work.
I. Gather all other incidental data necessary for the preparation of rehabilitation contract documents.
J. A photographic record of the entire structure, all testing performed, structural and coating conditions, all appurtenances, OSHA and/or TNRCC violations, site conditions and surrounding areas, etc.

Approximately 30 working days after completion of the PHASE I field work, we will submit to the OWNER a Detailed Inspection Report on the tank. This Report will include, but is not necessarily limited to, the following:

A. A comprehensive written report addressing in detail all the findings of the
inspection.
B. Approximately 50 to 100 mounted and descriptive color photographs.
C. All field and laboratory tests results.
D. Tank sketch showing all dimensions and member sizes.
E. Site conditions.
F. Detailed recommendations for the repair and painting rehabilitation work.
G. Recommendations for waste disposal (if required).

The Inspection Report, which will become a part of the contract documents for the rehabilitation work (PHASE II work), will be prepared in such a manner as to provide each prospective bidder with a sufficient amount of descriptive and photographic data to prepare precise estimates without normally having to visit the tank site.

The Report will also include, under separate cover, a breakdown of construction costs estimates based on the Report recommendations. >>Phase II
