Q11. If a contractor is on design team, can the contractor bid construction (integration and controls, specifically)?

A11: A contractor can be part of the design team as a subconsultant but contractor must separate themselves from the consultant Team after design is completed and prior to any bidding activities and construction. Consultant should explain in their proposal how they would accommodate this and avoid any conflicts of interest, including the construction management scope of work.

Q12. Do Town have a preferred integrator for SCADA?

A12: No

Q13. Does the scope include upgrading or changing the existing switch for backup power? Ask because scope specifically mentions switchgear.
