About this file
This is an Engineers Estimate document prepared by the Department of Environmental Protection (DEP) for the Kempton Refuse Rehabilitation project, issued as part of Addendum No. 3 to ARFQ DEP25-09. The project encompasses comprehensive rehabilitation and restoration work at the Kempton refuse site, including site preparation, removal of existing acid mine drainage (AMD) treatment systems, installation of new AMD treatment infrastructure, erosion control measures, revegetation efforts, and construction of various channels and containment structures. The scope of work includes mobilization and demobilization, construction layout, quality control, site preparation activities, aggregate and fabric installations, fencing and gates, ditch reclamation, stabilized construction entrance, silt fence and erosion control products, revegetation with standard and pollinator seed mixes, geotextile and HDPE liner installations, extensive piping systems, valve installations, weir structures, riprap-lined channels of varying dimensions, concrete vaults and inlets, and subsidence depression repairs across the project site.
The total estimated project cost is $1,875,220.00, with individual line items ranging from $450.00 to $337,500.00. Key cost components include AASHTO #4 limestone for AMD system rehabilitation at $337,500.00, grouted riprap trapezoidal channels at $144,900.00, geotextile and HDPE liner installations totaling $46,600.00, and various piping and drainage infrastructure elements. Cost limitations are imposed on specific bid categories, including mobilization and demobilization capped at five percent of total bid, construction layout at five percent, quality control at three percent, site preparation at ten percent, and administration costs at three percent. The DEP reserves the right to request additional information and supporting documentation regarding unit prices when they appear unreasonable, ensuring cost reasonableness and project feasibility.
