Please confirm all purple lines will be removed by demolition contractor.

Are the area designated as "replace lines" - "pink areas" also part of the work?Please confirm that remove and replacement of "pink lines" is not part of the scope of work. Is there a list of the lines to be demolished as the colors are not clear in case of laterals and manholes.Please confirm all laterals coming off of purple lines are also purple.

Specific colors in the drawings are not relevant, these were the drawings provided that best showed the infastructure to the best of CES knowledge. We have adjusted the bid schedule to provide for a maximum SF/LF to be demo'd, as well as asking for a unit price for both items. Based on timeframes to demo/construct around these areas, contractors will be instructed which lines to demo as the project progresses. If timeframes do not allow for the demolition of the total maximum square footages given in the line items, the Government shall base the amount to be removed from the contract based on the unit price given. The SF given for pavement removal will most likely still include the blue hatch shown in Appendix A Map, however more concrete information will be provided upon award for both the exact areas of pavement and utilities to be remove, and changes made accordingly.
31General InquiryAre the sewer line re-habilitation areas also a part of scope?

Please confirm the green lines and rehabilitation work are not part of scope. If they are part of scope please provide rehab specification.
