His clients include commercial waste disposal firms, municipal and local governments, petrochemical manufacturing, utility, pulp and paper processing industries, and land development firms in the Southeast and Midwest U.S. Kwasi specializes in landfill design and permitting, geotechnical investigations, containment system and confined disposal facility (CDF) design, dredged material management, sediment capping, shore protection rehabilitation, resident engineering, and construction management/quality assurance.
Kwasi served as the on-site project manager, resident engineer and certifying engineer for the Fernald remediation and closure project in Fernald, Ohio, a facility designed for the safe disposal of 2.5 million cubic yards of low-level radioactive waste and mixed waste. He was also responsible for the design, construction, and performance monitoring of an innovative final cover system for the closure of very low shear strength, compressible paper-mill sludge impoundment in Ohio. His work on this project was documented in a paper he coauthored "Evaluation of the Performance of a Pulp and Paper Mill Sludge Landfill Final Cover System" which received the 1999 TAPPI Russel O. Blosser Memorial Best Paper Award. Kwasi is presently the principal geotechnical engineer and program manager for multiple geotechnical and sediment related projects at a liquefied natural gas (LNG) facility on Savannah Harbor, Georgia, where he is responsible for maintenance dredging management; geotechnical investigation, design and construction oversight of CDF dike raisings; shore protection rehabilitation design and construction oversight; and dredging permit renewal applications, including wetlands delineation and mitigation plans. Kwasi has been involved in the design, permitting, construction, and closure of over 50 solid waste management and containment system facilities in 15 states. He has published more than 50 papers on sediments, dredge material management, landfill design and solid waste issues.
