David Bonnett is a Principal Engineer based in Massachusetts with 30 years of experience focused on water and natural resources engineering and waste containment facility planning and design, including environmental design, permitting, and construction oversight.
He has significant experience with construction quality assurance (CQA) and construction management (CM) for the installation of geosynthetics and soil liners for waste management facilities and for remedial construction activities for Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) closures, and Resource Conservation and Recovery Act (RCRA) sites. He has been involved in over 1,700 acres of lining system installation and closure construction.
In situ containment systems and the installation of a wide variety of appurtenances associated with leachate detection/collection systems and landfill gas collection/extraction systems are included in David's design and construction expertise. He also has experience with the construction of mechanically stabilized earthen (MSE) berms, interceptor trenches/vertical barriers, and a variety of remediation technologies.
David has been involved in water resources-related engineering designs using low impact development (LID) concepts and is familiar with the biotechnologies and restoration of wetlands. He has overseen the development of renewable energy, including the use of photovoltaic solar panels on closed landfills and landfill gas-to-energy projects.
As part of his construction management practice, David has been the liaison between client, contractor, and regulatory agencies, and has overseen the development of technical specifications, CQA plans, construction bid documents, design and construction drawings. Additionally, he has conducted field audits, helped to identify potential construction problems, and assisted with implementation of solutions. He has conducted numerous design and constructability reviews for waste management facilities and has provided construction claim support. He has provided litigation support on numerous landfill failures and has performed third-party reviews to resolve a variety of problems. David takes a solutions based approach to issues to find a cost-effective resolution to a problem.
