Landmark Science & Engineering is a leading consulting firm that offers civil engineering, surveying and natural environmental sciences. We plan, design and manage these diverse, integrated services to provide our public- and private-sector clients with innovative site solutions and value-engineered results for their important land development and building improvement projects.

Recognized for our high-quality planning and site design services and comprehensive focus on sustainable, low-impact site design practices, we are always mindful of the importance of being responsive to our clients’ needs.

Whether your project is an individual task, wetland/forest delineation, bog turtle investigation, stormwater improvement, or a complex, multidisciplinary, multi-phased, mixed-use project or brownfield redevelopment, our professional staff have the comprehensive local knowledge, understanding, relationships and credentials needed to achieve a successful project outcome.

Landmark’s clients benefit from having “one source” to meet all their site design, environmental, surveying, and construction-phase needs. From the earliest stages of due diligence, we’ll get the answers you need to make informed decisions – through tabletop reviews, natural resources mapping, surveys, and/or Phase I ESAs. We will take your project through all phases from start to finish – from planning, surveying, schematic and design development, approvals and environmental permits, construction documents and bidding assistance, to construction-phase management, survey stakeout/as-builts, CCR services and final project closeout.
