Engineering services offered by Divney Tung Schwalbe cover the full range of site and civil engineering disciplines. During a project’s feasibility phase, our engineers will review the proposed program, existing site conditions and surrounding infra­structure to help formulate strategies for the provision of essential services and access.  Early engineering studies can generally be based on available aerial photographs and topographic mapping to save time and expense, while detailed engineering design will require site-specific surveys. 

Our engineers often prepare preliminary site plans for a number of alternative project schemes, which may also include analyses of earthwork cut and fill, utilities, and roadway costs.  The preferred alternative can then be further developed in a series of site layout, grading and detail drawings.  Divney Tung Schwalbe also provides site utility design and coordination for sanitary, water supply, electric, gas, telephone, cable television, and site lighting systems.  DTS’s engineers and landscape architects work closely together to create stormwater management  systems consisting of both vegetated and man-made components providing water quality and quantity treatment in an efficient and sustainable manner.  In combination with our integrated erosion and sedimentation control measures, our “low-impact” site designs help to streamline the review and approval process.

Other engineering services offered by Divney Tung Schwalbe include the preparation of subdivision, site layout and utility coordination plans with full dimensional control, critical for coordination on "tight" sites.  DTS engineers will also provide construction phase support to review shop drawings, prepare schedules, conduct site observations, or administer permit compliance.
