Innovation: For nearly 65 years, Delve Underground has focused on providing full-service design and construction services for underground infrastructure projects. We’ve earned a reputation for delivering practical and constructible solutions for challenging projects. Constructability: Our constructability expertise is honed through on-going collaboration with contractors under all major delivery methods, has given us unique insight into managing construction risk and delivering fully detailed designs, calculations, and cost estimates. Having this unique insight has allowed us to integrate constructability in our designs through all stages of work, improving safety, ensuring efficient use of materials, and embedding reduction of public impacts in key design decisions. Rehabilitation and reuse: We assess facility conditions, develop rehabilitation concepts, and provide preliminary cost estimates and schedule analysis for repairs. Through our team’s expert inspection, analysis, and rehabilitation planning, the longevity of a tunnel, for example, can be extended, whether as an alternative to new construction, to accommodate a change in usage, or to address tunnel deterioration and/ or failure. Sustainability support: Our work is tailored to our clients’ needs and requirements. We work directly for agencies with some of the most aggressive sustainability goals in the country; we also support contractors under alternative delivery methods to meet defined project sustainability requirements. We collaborate to develop a strategic approach with our clients, efficiently adopting, embedding, and delivering appropriate industry rating schemes and standards that measure and drive sustainability outcomes. Support of small and disadvantaged businesses: Delve Underground promotes diversity and inclusion for our project delivery partners. We have a history of meeting and exceeding pre-established goals for small business firm participation on our projects. As part of our team, these firms, led by experts in their own rights, engage in meaningful ways on projects that they could not pursue on their own, building their qualifications and helping to sustain and grow their businesses. Environmental protection: Protecting the environment and our natural resources is woven into the culture of Delve Underground, both in our office environments and through the projects we design. Many of our projects are inherently beneficial to our planet’s environment, such as our CSO work that promotes cleaner waterways, and our rail transit projects that reduce air pollution and greenhouse gas emissions. Our team includes LEED-certified personnel and Envision Sustainability Professionals (ENV SP) to assist clients with achieving simultaneous environmental, social, and economic outcomes to achieve measurable sustainability on projects.
