Black Brook RFQ Questions & Answers (Q & A)

Q1: Is there a set-aside for SBE/DBE/EDGE firms?

A1: No, there is not a set-aside, but we encourage submittals from SBE/DBE/EDGE firms.

Q2: On page 3 of 38 in the RFQ document under item 1 of the Consultant Scope of Services, it indicates that the Consultant will be installing monitoring equipment and collecting streamflow data. We understand this to mean that we will be installing additional equipment and monitoring it for streamflow data, and that we will also be provided water level data from the already-installed HyFi sensors, is that correct?

A2: Consultants will be provided the water level data from the already-installed HyFi sensors.  If consultants need additional data to calibrate the model, they need to collect that additional data as part of this contract.

Q3: On page 3 of 38 in the RFQ document under item 3 of the Consultant Scope of Services, it states the Consultant will "identify alternatives based on level of services goals to mitigate areas prone to flooding which pose health and safety risks." Have the project partners already identified level of services goals to be used in the alternatives analysis, or will the Consultant be developing level of services goals with the project partners during the pre-design phase?

A3: Level of service goals will be determined based on model results.  A 100-year level of service would be the initial goal if it is feasible.

Q4: On page 16 of 38 in the RFQ document under "3. Hydraulic and Hydrologic (H&H) Modeling Strategy," It lists main H&H input parameters. When using the SWMM model, is using the Green-Ampt infiltration methodology acceptable instead of the curve number method?

A4: Consultants will be responsible for choosing and defending model choice and parameters. The Green-Ampt infiltration methodology would be acceptable.
