Laser Scanning: How Our WBE Speeds Up Construction

| November 7, 2017

by Laureen Poulakis

How do we speed up construction? Are there innovative tools to assist us with accuracy while maintaining integrity of the built environment? For years, contractors and design teams have sought ways to shorten timelines and increase precision.

As Boston’s market continues its pace, our team at Brennan Consulting is providing a unique delivery of civil and survey. We continue to look for ways to set us apart here in New England. Our long-standing experience in laser scanning has brought an increase in demand for these services. Laser scanning, also known as high definition surveying (HDS), is a process of high-accuracy mapping that uses laser beams to capture complete three-dimensional detail of the built environment.

To minimize risk, laser scanning can be used to:

  • Obtain as-builts of existing columns, floors, façades, and mechanical equipment.
  • Assist during tenant fit-up on large project construction.
  • Reglaze entire buildings.
  • Relevel concrete floors and calculate new dead loads.
  • Connect existing to new construction.
  • Modify building massing to provide nonobstructed views to a billboard/sign.
  • Renegotiate leases due to reduced visibility of a billboard/sign post-construction.

Brennan Consulting surveyors are currently working on the Perry Hall project at UMass Lowell; a $50 million renovation of its historic Engineering Building. According to UMass, the renovations “will create flexible, medium-service labs in areas central to the Massachusetts economy, including biomedical, chemical, and environmental engineering, as well as biomanufacturing and clean energy.” Brennan’s laser scanning services are being used to relevel existing concrete floors, calculate added dead loads, and provide a comprehensive analysis of future structural issues prior to construction.



75 Braintree Street, Allston Mass., for Waypoint Companies

Brennan Consulting is also performing civil, survey, laser scanning, and permitting for one of the latest residential developments by Waypoint Companies. The six-story mixed use project in Allston is located between Braintree Street and the Massachusetts Turnpike. Young professionals are the target audience for the 80-unit apartment complex with restaurants, shops, clubs, and underground parking. Construction is currently wrapping up, and the building is LEEDS Certified Silver, headed for Gold.

Brennan surveyors performed mobile laser scanning to ensure that a Clear Channel billboard onsite would not lose visibility due to the new construction. The Massachusetts Turnpike and project neighborhood were laser scanned from the view point of passenger vehicles. A 3D model of the new building was then superimposed on the mobile scan, illustrating that the top three floors would partially obstruct the billboard. Working with Brennan engineers and surveyors, the architect redesigned the building early in the process, allowing the client to preserve the billboard’s viewshed and honor Clear Channel’s 99-year lease.

Brennan Consulting delivers several unique services to minimize client risk

The viewshed study for 75 Braintree Street and the concrete floor redesign at Perry Hall are no exception. Working with Brennan, contractors and design teams are finding laser scans identify issues early in the process, saving stakeholders time and money. Stop by to learn more.
