CONTACT & LOCATIONS NEWS MENU ≡ MARKETS Property Development Balancing physical and environmental constraints Because development often occurs within accelerated time frames and tight budgets, we partner with owners and developers to streamline the permitting process, address existing environmental conditions, identify optimal site layout, and tie-in to existing infrastructure. Our geotechnical experts evaluate soil suitability for excavation and structural support, and determine special requirements for structures in seismically-sensitive areas, waterfronts, areas with permafrost, and wetlands. Committed to sustainability, we work with design teams to successfully meet owners’ Leadership in Energy and Environmental Design (LEED) requirements.
