Plan Sheet / Specification Reference= Hydorseed (Polymer Stabilized Fiber Matrix) Type 1- ESA Area and Type 2 Landscape area.


Question= The Bid Form provides only one line item for the Polymer Stabilized Fiber Matrix of 131,000 sf. There are two areas Type 1 seed and Type 2 seed. The Landscape plans show a total area of 177,289 sf
excluding the ESA area for Type 2. A take off of the landscape area totals aproximately 148,358 sf. And no quantities are provided for the ESA areas and an adequate take off can not be provided for the ESA area
due to the large ESA area not being completely visible on the plan sheet. Since the seed mix is different for both areas please provide a quantity for the ESA area to get an accurate quote on the Type 1 seed mix. Secondly please clarify quantity for the Landscape area type 2 and the bid form quantity of the Landscape area. Is this bid line item also to include the ESA area?

 

  • Yes, the bid line item #44 includes the ESA area.
