CQA

Construction Management (CM) and Construction Quality Assurance (CQA) are two very important components of our landfill services.  A landfill is expensive to build and must be built correctly; synthetic liners further complicate construction. For nearly twenty years, Weaver Consultants Group has provided construction services for the installation of thousands of acres of landfill liner and final cover systems. Our CM experience helps us to design cost-effective and buildable landfills.  Our CM and CQA services include the following:

• Contract and bidding documents;
• Contractor and bid evaluation;
• Scheduling, cash disbursement, and cost analysis;
• CQA services including inspection and testing;
• Progress payment evaluation;
• Regulatory agency contact;
• Changed conditions evaluation;
• Design modification and shop drawing review; and
• Preparation of CQA documentation and other pre-operational requirements.

Experienced CQA personnel are necessary to ensure that a landfill is constructed in accordance with its permitted design.  Our project managers and field personnel are very experienced providing CQA services for: 

• Soil liner and soil cover;
• Geomembranes, geotextiles, geonets, geogrids, geosynthetic clay liners, and geocomposites;
• Leachate collection systems including drainage media, piping, and collection sumps; and
• Landfill gas management system installations including extraction wells and header piping.

Weaver Consultants Group personnel are very knowledgeable of the federal, state, and local regulations that typically impact siting, permitting, design, and construction of landfills. Years of experience, and years of working side-by-side with many regulatory agencies, prepares us to perform these services.  Our reputation for honesty and integrity has in many cases allowed us to obtain permits and operating approvals in less time than typically required, which highlights our commitment to the quality of services we provide to our clients and our relationship with state agencies.
