Boston, MA – The Parcel 7 Fenway Center Development is a “Smart Growth” transit-oriented development that will be located over the Massachusetts Turnpike and Commuter Rails and on a surface parking lot between the Beacon Street and Brookline Avenue bridges.
The project surveyor, Harry R. Feldman, Inc. was retained to begin the survey work immediately for this complex air-rights project; however, the client needed time to work out access agreements with the various authorities.
The Feldman team utilized both conventional field survey equipment and their 3D Laser scanner to survey the Highway, Rails and Bridges from remote locations and obtained the topography in the roadways, the track and bridge abutment locations as well as the elevations of the bridge decks for the design of the project. The deliverables included 2D Plans, AutoCAD files and elevation views of the project area. The use of this technology not only kept the project moving, but it saved the client money since they did not have to incur fees for lane closures during the entitlement phase of the project. While there are other methods to obtain data remotely, such as photogrammetry, the results would not be the same ¼” accuracy that was attained by the 3D Laser Scanning team.
After access agreements were completed, the Feldman team then performed additional 3D scanning and traditional survey work from the surface of the Mass Pike as well as the project area which includes Beacon Street, Brookline Avenue and Maitland Street. Meticulous procedures were followed to establish survey control for the high level of accuracy achieved for both the existing conditions data and for future construction layout. Since this project entails building a deck over the roadway and tying into existing bridge decks, the team provided detailed sections along bridge abutments. All of the bridge information including the slab and the structural elements under the bridges was acquired in just a few hours without the need for scaffolding or lifts.
This Fenway Center survey is an example of how the combination of traditional survey methods and 3D Laser Scanning technology will yield the highly accurate results consultants require for the design of their projects. This methodology provided both the safest and most cost effective solution that owners and clients need during these difficult economic times.
