JBAB Paving MACC – Seed Project – Maintain B370 Parking Lot 9 February 2023 Questions and Answers

* All the RFI responses that were received are included in this document. Many of the questions are duplicates.

1. 2.3 AE Design Services Please confirm that no design is required for this project to include construction drawings and specifications.

A: No design required, but there are Base Wide Paving Specifications per Attachment 1 that must be followed. See Revised SOW 2.3

2. 2.4 Digging and Environmental Requirements Is any portion of the work associated with the replacement of the concrete sidewalks considered to be “disturbance” in the eyes of JBAB ENV or DOEE?

A: DOEE specifications are to be followed in its entirety. Land disturbance activity is defined below. The Gov’t does not anticipate any major land disturbance as long as the contractor does not disturb/expose the underlying soil. It is not considered land disturbance. The excerpt below is from DOEE Stormwater Guidelines for your reference.

Land-disturbing activity – Movement of earth, land, or sediment that disturbs the land surface and the related use of pervious land to support that movement. Land-disturbing activity includes stripping, grading, grubbing, trenching, excavating, transporting, and filling of land, as well as the use of pervious adjacent land for movement and storage of construction vehicles and materials. Additionally, land-disturbing activity includes excavation and other activities which expose soil within an existing building footprint only if at least one exterior wall is removed fully or in part during construction in order to accommodate movement of construction equipment, workers, or material. Land-disturbing activity does not include repaving or milling that does not expose the underlying soil.
