At W. M. Lyles Co., we rely on comprehensive geotechnical investigations provided during preconstruction to inform our planning and execution strategies. We use this data to assess subsurface conditions, manage groundwater challenges, and adapt our excavation and shoring approaches to reduce risk and ensure safe, efficient progress. Our team works closely with owners, designers, and geotechnical engineers to turn technical findings into practical field solutions.
W. M. Lyles Co. transforms raw land into construction-ready sites for California’s most critical infrastructure projects. Our comprehensive site preparation services establish the groundwork that enables successful project delivery from day one. Drawing on eight decades of experience and robust self-performance capabilities, we handle every aspect of site development—clearing, grading, utility coordination, and environmental compliance—with the precision and reliability that define our approach to construction.
