Sewall professional engineers provide civil engineering services to retail and commercial developers and to schools, hospitals, and other institutions that serve the public. With over 100 years’ experience, our team is known for superior design and construction management and a creative solutions approach to complex problems. Understanding that many factors impact project success, we work closely with clients, local planners and permitting agencies, advocacy groups and citizens to balance multiple needs and interests with regulatory and budget requirements.

Retail/Commercial Site Design and Development

As a vendor of choice for several major retail and commercial developers, we offer the following site design and development services:

  • Project planning and fatal flaw analyses
  • Surveying, aerial photography, and topographic/3D mapping
  • Rezoning, land development and environmental permitting
  • Site and storm water treatment design; erosion and sedimentation control planning
  • Utilities design: water, sewer, electric, and gas

Building Design and Assessments

To improve the quality of work, study, and living spaces, Sewall engineers provide design and assessment services for schools, hospitals, nursing homes, municipal buildings, military facilities, retail/commercial developments, industrial buildings, prisons, and other private institutions throughout Maine and New England, including:

  • Structural design for new construction and renovation, ADA, and code compliance assessments
  • Renovations and facility improvements design
  • Facility design and permitting
  • Construction and renovation inspections

Asset Maintenance and Pavement Management

Once their facilities are built, our clients need to monitor and maintain them. We assist our clients by implementing and hosting web-based management systems integrated with GIS. These systems are the most efficient means to collect, house, access, analyze, and update information on facility assets, including:

  • Utilities (water, sewer, storm water, electric systems)
  • Pavement (pavement condition and management plans, markings)
  • Signage and traffic signals
