"Section 01 45 00 of the specifications outlines the requirement for a CQC System Manager who may, under certain circumstances, serve as the Superintendent. The section also refers to a list of specialized CQC support personnel to assist in the quality control process. However, the solicitation does not clearly state (please advise): a. Whether the Government expects the CQC System Manager and Project Superintendent to be two separate full-time onsite personnel, or if a dual-hat approach is acceptable for this project's scope and complexity. The prime contractor must maintain a directly employed designated responsible individual onsite in order for any work to be performed onsite to coordinate and control that work. This requirement cannot be subcontracted or delegated to a subcontractor. To maintain project continuity and to avoid work stoppages due to lack of the Prime Contractors personnel being onsite, the VA recommends that there be two designated responsible individuals onsite as onsite work increases beyond a single trade crew. b. Whether the CQC support personnel (electrical, mechanical, civil, environmental, etc.) are required to be full-time onsite, available on-call, or available periodically during relevant work phases. (Can these be the subcontractor's foreman/superintendent or directly employed by the Prime?) Project CQC support personnel can be full-time onsite, available on-call, or available periodically during relevant work phases as necessary to due-diligently support the project's schedule and provide the inspections required by project specification sections applicable to the project scope of work in a timely manner. The prime contractor must maintain a directly employed designated responsible individual onsite in order for work to be performed onsite. The Project Superintendent is responsible for all aspects of the project work quality and shall be subject to removal by the contracting officer if there are demonstrated lapses in quality control of the work required to be performed. Lack of adequate onsite support personnel shall not be an excuse for breakdown in quality control relative to submittal reviews by the contractor completeness and adherence to specification requirements, completion and submission of daily work and inspection reports, timely submission of outage requests, inspection readiness notifications to the VA and submission of required schedule updates. The CPM schedule will include as unique individual work activities for each system and work phase all required Inspections, including VA witness requirements, for Weld Testing, Welding, Piping Installations (Flushing, Hydrotesting), Equipment Start-ups, Concrete Pours, Boiler Safety Device Testing, masonry tuck pointing, etc. c. Whether the Government has a minimum expectation for the number of full-time onsite CQC employees directly employed by the Prime Contractor (excluding subcontractor staff) during active construction. The VA's expectation as defined in the specification 01 45 00 is that the contractor shall employ, and/or directly contract, during construction installations CQC inspectors with demonstrated experience and expertise providing quality control inspection in the prime scopes of work relative to this project; ASME and AWS welding programs and NDE testing, Steam Piping systems, Condensate Piping Systems, Feedwater Piping systems, Fuel Oil and Fuel Gas piping systems, Large Boiler Installations and Testing, Boiler and Steam System Controls, Boiler Operations, Electric Power Systems and Switchgear, Electric Power Raceway and Wiring, Structural and Miscellaneous Steel, Concrete Installations and testing, Masonry Restoration, Roofing System Installations, Building Envelope systems and Industrial Coating Systems. Each inspector will be required to read and maintain a copy of the specifications applicable to the work being performed, along with copies of referenced standards, to understand the project requirements and thus to aid in determination if the work is being performed per contract requirements. The CQC inspectors are required to be onsite when the work applicable to their experience and expertise is ready for inspection and prior to being covered or made in-accessible for inspection without having to perform re-work. 60.

Please clarify if a superintendent can be a dual hat to cover the requirements of QA/QC? VA Response - Section 01 45 00 of the specifications outlines the education and experience requirements for a CQC System Manager who may, under certain circumstances, serve as the Superintendent. Those circumstances are primarily related to the volume and complexity of work being performed. The prime contractor must maintain a directly employed designated responsible individual onsite for any work to be performed to coordinate and control that work. This requirement cannot be subcontracted or delegated to a subcontractor. To maintain project continuity and to avoid work stoppages due to lack of the Prime Contractors required personnel being onsite, the VA recommends that there be two designated qualified and responsible individuals onsite as onsite work increases beyond a single trade crew. Per the specification requirements, the experience and education requirements for the designated alternate CQC manager are the same as the Primary designated CGC Manager. 63. If no to the question above, will the QA/QC need to be full time for this project? See Response to Question 62) above. 64.
