Question= A careful reading of the referenced special provisions sections leads one to believe that there is roadway excavation containing aerially deposited lead within the project limits and that material is to remain on site and that there is surplus excavated material that becomes the property of the contractor and shall be disposed of off-site.

How is the contractor to determine how much material contains ADL and is placed on-site where, and how much material does not contain lead and is to be hauled off site?

  • See addendum #2.  Attention is directed to section 5-1.08 "Supplemental Project Information" of the contract Special Provisions and Section 19-2.06 of the Standard Specifications.

  Q:10/07/09
R:10/14/09

Plan Sheet / Specification Reference=Reference is made previous question No. 6 dated 8/21/09, and the answer dated 9/16/09.

Question=The answer provided as referenced above is totally inadequate. The information referenced in the answer (10 volumes of soils investigation)relates to the exploration of the existing condition only. The referenced soils investigation reports make recommendations that the ADL be placed in embankment and covered with pavement or one foot of clean dirt. The soils investigation reports are not contract documents. The contract documents provide no guidance whatsoever regarding the quantification and/or disposition of ADL dirt. There is nothing to indicate that there is any embankment to be built on this contract. There is no direction in the contract documents regarding placement of ADL dirt under any pavement or other improvement. The original question stands: How is the contractor to determine how much material contains ADL and is placed on-site where, and how much material does not contain ADL and is to be hauled off site? Other projects in this district have provided explicit direction regarding the various methods of encapsulating the ADL in the finished work. These project documents must provide the same explicit direction.

  • Please bid per the contract documents. Refer to Section 19 "Earthwork," of the Standard Specifications.
