Box 324 Wappingers Falls, New York 12590 Attention: Constance O. Smith Reference: Rockingham Farms Storm Drain Project f)15 RECEiVt::D~ {)(!fl s::? 0 3 1996 SUPERVISORS OFFICE TOW~f OF~'1.<",PPINC[n. Dear Supervisor Smith: As you are aware, we are out to bid for the above referenced project. We are also in the process of finalizing the easement agreements with the necessary properties and expect to have the last three easements signed and sealed well before opening of the bids. In any event, if there is problem with the easements, the Town has the right to hold the bids for forty-five (45) days and/or at the end of that period reject any and/or all bids. In the contract, one of the largest cost components of this project will be the necessary rock excavation to install this large diameter storm drain. It was our original intention to come in and do soil borings prior to the project to determine the amount of rock. This would allow us to put an accurate (:l: 10%) amount in the bid proposal for the estimated quantity. Because of all of the problems and time it has taken to obtain the easements, we have made the decision not to do the borings. This will eliminate the cost of doing the borings and reduce the impact on the easement givers. With that in mind, we have estimated the amount of rock that will be necessary to install the main. This estimation is based on our knowledge of the area that we obtained in doing the sewer force main for the Rockingham Farms Sewer project. Joseph E. Paggi,Jr., P.E. Ernst Martin, Jr., P.E., L.S. @ printed on recycled paper Constance O. Smith RE: Rockingham Drainage - 2 - August 29, 1996 The upside of not doing the borings is that we do not incur the cost of the borings which is approximately $5,000.00 - $7,000.00, and we do not disturb the easement areas prior to the actual construction. The down-side is that we do not know the exact quantity of rock, and that if more rock is encountered than estimated, than additional costs will be incurred by the Town. I have been fairly conservative in our estimation, however, want to alert the Town that there could be an overage in this item. We, obviously, keep accurate daily records of the rock, and will keep the Town informed on a weekly basis of quantity and how it compares to what we have estimated. One item to keep in mind is that, in any event, the rock will need to be taken out to implement the project. Therefore, the cost can not be considered additional cost only unknown at this point in time. If there are any questions or comments, please do not hesitate to contact this office.
