Report on advertisement of Request for Proposal 15-RFP-15 Boiler Condition Assessment at the Stickney Water Reclamation Plant, estimated cost $100,000.00, Account 101-69000-612240
Body
Dear Sir:
Request for Proposal (RFP) documents have been prepared for 15-RFP-15 Boiler Condition Assessment at the Stickney Water Reclamation Plant, at the request of the Maintenance and Operations Department.
The purpose of this request is to procure the services of a boiler condition assessment inspector to conduct assessments on Stickney boiler Nos. 3, 4 and 5. The assessments will include: visual and borescope tube inspections; ultrasonic thickness measurement of headers, firebox tubes and both steam and mud drums; Magnaflux testing (dry or wet) of selected inside welds of the steam drum followed by Phased Array ultrasonic testing for any subsurface defects; dry powder Magnaflux testing on accessible and designated tube holes for signs of ligament cracking followed by liquid penetrant (ZYGLO) testing, as necessary; field Eddy Current testing of all hard to reach steam generating tubes and convection sections to determine volumetric wall loss of tubes; in-place metallography or replication of six (6) tube sections to determine any change in component properties, such as carbon content, creep, void, microstructure or any other chemical element that might affect yield and tensile strength; scale chemical analysis; infrared testing and assessment while the boiler is in operation to determine defective casing, refractory and/or insulation; a boiler efficiency analysis and test while each boiler is in operation, and a risk-based evaluation made for every individual pressure retaining component. Upon completion, a comprehensive report will be submitted including CAD drawings of the ultrasonic tests, metallurgical analysis, fit for service analysis, and remaining life calculations and recommendations in compliance with the National Board Inspection Code (NBIC).
These services are needed to determine the remaining useful life of the boilers and recommend any rehabilitation work.
The estimated cost for this RFP is $100,000.00.
No bid deposit is required for this RFP.
Appendix A will not be included because the estimate is less than the minimum threshold established by Section 4 of the Affirmative Action Interim Ordinance.
The tentative schedule for this RFP is as follows:
