BDO Engineering, based in Mansfield MA, has provided engineering and support services in the civil engineering field since 1995. The majority of our projects are in southeastern Massachusetts but we occasionally travel throughout Massachusetts, Rhode Island, Connecticut, and New Hampshire.




Engineering Services We Provide


Septic Systems: Residential and commercial septic system designs (new construction and repair of existing systems), soil evaluations, percolation tests, topographic surveys, as-built plans.


Site Plans: Preparation of site plans for municipal review. Site plans include buildings, pavement, grading, utilities, parking, lighting, etc.


Drainage Studies: Drainage studies for subdivision and site plan design. Drainage studies compare runoff from the pre-construction site with runoff from the post-construction site. Drainage structures and best management practices are used to retain and infiltrate runoff as required.
