Spec 15141 – 1.01 D. “Flanges shall be Class F…” Please verify if all flanges shall be 250# Drilling Class “F” or just the required line A with 250 PSI Pressure. Response: Pipe flanges are specified in Section 15065 – Steel Process Piping. Flanges for couplings, connectors and adapters shall match the corresponding flanges on the piping, valves, etc. See “Changes to the Specifications” note 12, Section 15141.
22. Ref D-202 - Can the 14” Gate Valves be provided with 125# Flanges (Gate Valves Rated for 250 PSI) and Class “E”
Steel Flanges Response: ASME B16.1 Class 125 flanges are acceptable on Class 250 valves.
23. Ref C-302. Does the existing 24” BFV have 125# Drilling or 250# Drilling Pattern?
Response: The pipeline is currently under construction. The Contractor shall field verify and match the drilling pattern of the existing 24 inch BFV during the construction phase of this project.

Class “E” flanges can be used with are rated at 275 PSI. Response: Yes, ASME B16.1 Class 125 flanges on Class 250B butterfly valves are acceptable. “Changes to the Specifications” note 11, Section 15101.
25. Are the proposal forms available in an editable format (i.e. Microsoft Word) or should we plan on including editing
with an adobe.pdf typewriter feature and include attachments or appendices as needed to adequately respond to the questions? Response: The Evaluation Criteria Forms are now available in Word format and can be found on the SAWS website.
26. Regarding the Key Subcontractor forms, with us bidding as prime, we will be self-performing the tank
construction; however, we will carry a site work sub (i.e. dirt work and yard piping). Typically when we are sub, the GC’s self-perform the site work but carry us as a Key Subcontractor. There is not key subcontractor form for a Site Work Subcontractor. Should we manually edit the tank builder form to be a Site Work Subcontractor Form or should we copy one of the forms to add a Site Work Subcontractor? Site Work will be a sizable portion of the project scope. Response: Respondents can manually edit the top of the forms to indicate the correct name of the sub-contractors. The forms are available in Word format and can be found on the SAWS website.
