The Millersville Landfill Compost Pad is projected to generate revenue for Anne Arundel County, Maryland, which is slated reduce the tax burden on residents.
DFI provided Construction Management and Senior Resident Construction Inspection services for the new compost pad. Responsibilities and duties included, at a minimum, the inspection of environmental controls and Storm Water Management (SWM) conversion, landscaping, trash fence and Quality Assurance (QA) testing of the mass grading operation. Additional work included grading of over four (4) acres of land that included concrete, asphalt and soils of the Contractor construction efforts, documentation of work and negotiated with the General Contractor (GC) change orders. Other work included providing constructability reviews, conducting and preparing minutes for progress meetings, maintaining item quantity ledgers, inspecting borrow sources and disposal areas, monitoring erosion control and preparing estimates. Additional responsibilities included acting as a liaison with the waste management staff, reviewing contractor payment requisitions and conducting semi-final and final inspections.
DFI was responsible for coordinating with the County Waste Management Systems (WMS) personnel, the Project Management, Design Team and GC for 5,104 tons of base course asphalt placement for the composting area of the project. Additional project responsibilities include the coordination of the material delivery truck traffic through the facility required additional GC support and adjustments throughout the day to ensure a smooth operation, which included thorough Quality Assurance and Quality Control (QA/QC) testing.
Highlights and innovative approaches from this project included the value engineering substitution of soil-cement for the Graded Aggregate Base (GAB). The GC and DFI worked together regarding calculations and QC testing procedures to mirror those of Maryland Department of Transportation (MDOT) State Highway Administration (SHA) practices. Once the necessary documents were submitted to the A/E and County for review, the findings found that the submitted soil-cement substitution provided higher modulus for the sub-base than the original paving section for GAB.
