Q5. Specification section 01 11 13 – 1.14.D.6 General Work Sequence for the RAS & WAS Pump

Station state to do the work without interruption to the process and provides only a short time for a shutdown period, 7-days, and 2-hours. This timeframe is not reasonable for this work due to the limited access and amount of work associated with scope of work. Several additional weeks would be required to perform the work for these pumps, piping, and associated electrical work. Please confirm a time extension for this work will be provided for actual durations required to perform this work.

A5. Alternate shutdown sequencing methods and outage durations will be evaluated for approval as part of the Process Shutdown Request. It is not expected that the work in the RAS/WAS Pump Station will be critical path and therefore, no extension is required for the overall contract duration. Revise Section 01 11 13, Paragraph 1.14.D. as follow:

The following is a description of proposed sequencing for major shutdowns. This sequencing of construction has been developed to provide one approach to complete the work and meet the constraints imposed. This list is not considered to be all inclusive and Contractor is responsible for accounting for producing a complete list of shutdowns required throughout the project, and establishing a final sequencing procedure for each required shutdown. The Contractor may perform the work differently than outlined herein and many work items can be performed during various times at the

Contractor’s discretion. However, the schedule with sequence of construction shall be submitted, reviewed, and provided with a favorable review by the City, regardless of the method chosen and all construction constraints must be met. All items shall be outlined in the contractor’s construction schedule.

Q6. Is the Lump Sum for Allowances ($550,000) included in the $2,200,000 Contingency Allowance?

Or are the Lump Sum Allowances in addition to the Contingency Allowance?

A6. All specified contingency allowances are included in the price(s) set forth below, and have been computed in accordance with Paragraph 13.02 of the General Conditions.

Q7. System Integrator Allowance covers Sect. 406111. Micro-Tec is specified. Yet, spec section

004332 requires an “Instrumentation and Control System Supplier Questionnaire. Please clarify.

A7. Instrument and Control System Supplier Questionnaire is not required. Remove Section 00 43 32 in its entirety.

Q8. Is inorganic zinc primer a mandatory requirement for all ductile iron pipe, fittings, and appurtenances receiving an epoxy finish system, or is it offered as a Contractor/Applicator option in lieu of an epoxy primer coat ("same as finish coats")?

A8. Per Section 40 05 19, Paragraph 2.2.A, a universal primer shall be used for ductile iron pipe, manufacturer’s standard. If in contact with treated or potable water, certify as being in compliance with ANSI/NSF 61 and ANSI/NSF 600.
