B. Thayer Associates (BTA) was founded in 1990 by Barbara Thayer. Licensed in both architecture and engineering, Ms. Thayer envisioned and established a firm that combines the intricacies of each discipline into a cohesive whole. The firm fosters a working environment dedicated to innovative design, teamwork, and client satisfaction.

The firm is organized into four major divisions: Landscape Architecture, Land Surveying and Mapping, Engineering, and Architecture. Integrated into these major divisions are specialized services that include: arborist services; site grading, drainage, and stormwater design; wetland delineation and mitigation; environmental and permitting services; historic preservation; planning; robotic, GPS, and laser scanning; civil, structural, and site design; bridge and highway design; traffic analysis; maintenance and protection of traffic (MPT); and construction phase services. With multiple LEED Accredited Professionals on staff, B. Thayer Associates provides integrated sustainable design on many of our projects.
