Matrix will prepare the required specifications and bid sheets for necessary asbestos abatement associated with the anticipated structure demolition activities. The construction documents will include specifications in Construction Specifications Institute (CSI) format. Construction documents will include requirements for asbestos abatement (removal), waste management, and additional health and safety procedures in accordance with New Jersey Department of Labor (NJDOL) and Occupational Safety and Health Administration (OSHA) requirements. Our costs assume the submission of abatement documents at the 100% Issue for Bid/Permit Phase only. Design drawings will not be included as part of Matrix’s construction documents. TASK 4 – CHARACTERIZATION OF BUILDING MATERIALS (I.E. CONCRETE AND CINDER BLOCK) It is Matrix’s understanding that the building materials (i.e. concrete, brick, cinder block) will be disposed of off-site as C&D waste. If this disposal method (C&D waste) is selected, then the sampling associated with option 1 below will be required. If the Township/redeveloper determines that they would like to re- use the materials on-site as sub-base under asphalt paved areas or dispose of the material at a Class B recycling facility, then the sampling associated with option 2 below will be required. If option 2 is the preferred disposal option, then the building material sampling is recommended to be completed in-situ (prior to building demolition) as per NJDEP recommendations, however this option does not guarantee the material can be re-used on-site. The qualification for on-site re-use will depend on the analytical results of the building material sampling. Costs for both options are summarized below. OPTION 1 If option 1 is selected, Matrix will collect the concrete samples for disposal after the building is demolished. Matrix will collect up four (4), 5-point composite building material (concrete and cinder/concrete block) samples (one composite sample per every 1,000 cubic yards [CYs]) for waste characterization purposes, as required for off-site disposal. Samples will be submitted to a New

e and cinder/concrete block) samples (one composite sample per every 1,000 cubic yards [CYs]) for waste characterization purposes, as required for off-site disposal. Samples will be submitted to a New Jersey certified laboratory for analysis of extractable petroleum hydrocarbons category 2 (EPH Category 2), target compound list/target analyte list plus a forward library search (TCL/TAL+30), full toxicity characteristic leaching procedure (TCLP), TCLP beryllium, Resource Conservation and Recovery Act (RCRA) characteristics, paint filter, and contingent hexavalent chromium analysis. Volatile organic compounds (VOCs) will be collected as a discrete grab sample and not a composite sample. If total chromium is over 20 milligrams per kilogram (mg/kg), contingent hexavalent chromium will be analyzed. The samples will be analyzed on a standard 14-day turnaround time. Upon receipt/evaluation of analytical results, Matrix will submit the required documentation to the receiving facility in order to have the material approved for transportation and disposal. OPTION 2 Based on previous site and remedial investigation activities and Site Plans, the structure measures approximately 49,800 square feet with a floor thickness of 6-inches. As part of this scope, Matrix proposes the collection of approximately 20 building material samples (15 samples from the DPW Building and five [5] samples from the Animal Control Building). Twelve (12) concrete chip samples are proposed to be collected from the building slabs (nine samples from DPW Building and three samples from Animal Control Building). Matrix proposes the collection of up to nine (9) cinder/concrete block samples (six samples from the DPW Building and two samples from the Animal Control Building). The total number of samples collected from each building material type is based on measurements collected by Matrix and building plans provided by the Township to determine the approximate volume of each material present in the existing building. All samples will be discrete surficial samples not to exceed 1-inch in depth and will be biased to any evidence of impacts (i.e., staining). All
