Lawrence G. Pinter, B.Sc., P.Eng.
Principal Environmental Engineer, Pinter, Saskatchewan

Lawrence is a geo-environmental engineer with specific experience in environmental site assessments, contaminant remediation, landfill sitings and design, and waste management. Lawrence has been involved in a number of major petroleum hydrocarbon, agricultural chemicals, heavy metals and dioxin and furans contamination assessment and remediation projects. His project list also included the siting, design and construction of landfills, hazardous materials storage cells and a composting facility. He has been involved in the assessing and decommissioning several old dump sites and landfills. His other work in hydrology and hydrogeology as well as heavy construction has provided him with a unique combination of knowledge and practical skills. It also has provided him with a detailed understanding and sensitivity to environmental concerns. His training and experience provides Lawrence with a unique and practical perspective and approach to environment issues, problems, emergencies and challenges particularly for First Nations and Northern Saskatchewan. He has been working and consulting in the geoenvironmental sector since 1987. He has permission to consult from the engineering associations in Saskatchewan, Alberta and Manitoba.


Ram Jagdat, B.A.Sc., P.Eng.
Consulting Engineer, Principal, Canada Engineering Services

Ram has over 40 years of diversified engineering experience in Geotechnical, Environmental and Structural Engineering. Major projects in which he was involved were the investigation, analysis of 350 miles of the Republic of Guyana Roads and the establishment of a model for maintaining these roads, including bridges and culverts. He worked as a project manager for a hydropower access road through jungle territory and later as a bridge design engineer, designing the abutments of a 1.25 miles long bridge – the world’s longest floating bridge. He was responsible for the monitoring of the rebuilding a of a 100 feet deep slope failure in Toronto. Other major projects he was responsible for was the rebuilding of a 100 feet deep slope failure in Toronto. He has carried out hundreds of geotechnical investigations all over Ontario, including investigations of numerous tailings dam projects in northern Ontario and was responsible for monitoring of deep foundations for many major high-rise buildings in Ontario, founded on caissons, piles and helical pile foundations.


Affiliate Geomechanica, Toronto, Canada

Associate Principal Engineers in rock engineering, having Ph.D. degrees from the University of Toronto and related project experience, are our team specialists in fundamental rock mechanics, rock mechanics testing, and computational geomechanics. We recognize the stability and failure of rock is an important consideration for our client’s shaft and tunnel construction, rock slopes and excavations, dam stability, open pit and underground mining, petroleum and nuclear waste disposal, and hydraulic fracturing projects, therefore we employ realistic simulation modelling tools to model rock fracture and deformation behaviour on massive rock sites.
