JANUARY 13:
Temporary Bracing During Demolition and Erection:
Not Just an Afterthought
Presenter: Diego Arabbo, PE | Senior Project Manager | Simpson, Gumpertz & Heger
|
|
PRESENTATION OVERVIEW:
Temporary bracing is critical to safely demolishing and erecting structures. Traditionally, contractors select, design, and implement the temporary bracing system, relying on their own knowledge and past experience to design the bracing without assistance from engineers or architects.
This dynamic works most of the time; however, improper or incomplete design of the temporary bracing system can result in localized damage to the structure, the collapse of a partially erected structure, or an unplanned collapse during demolition. These problems at best negatively impact the project cost and schedule, and at worst can lead to severe injuries or even death. Legal action between parties to resolve the project disputes commonly follows, which further exhausts time and resources from the involved parties.
This webinar will establish the importance of a properly designed temporary bracing system, discuss when temporary bracing is necessary, review the obligations of each party as it relates to design and implementation, and share lessons learned from several case studies involving failure evaluations.

JANUARY 20:
Facadectomy: Saving the Sage Hall Wall
at the Wellesley College Science Building
Presenter: Nathan Roy, PE | Principal | LeMessurier
|
|
PRESENTATION OVERVIEW:
A facadectomy is retaining a building’s façade while demolishing the building structure to make way for new construction.
This presentation will focus on the design considerations for facadectomies and the associated temporary structures to allow for an exterior wall to be maintained throughout the construction process.
A case study on the process and temporary support structures to allow for saving the original 1927 Sage Hall wall at the new Wellesley College Science Building will be highlighted.
|
|
PRESENTATION OVERVIEW:
The historic Climate Pledge Arena (originally named Key Arena) started out as part of the 1962 World’s Fair and is undergoing a major transformation into the new home for the NHL expansion team in 2021.
One large component of the transformation required the temporary shoring of the arena roof. This presentation discusses several key components of the roof shoring philosophy and procedure.

The Marr Companies consist of four separate and distinct entities: the original company established in 1898, Daniel Marr & Son Company (steel erection); Marr Crane & Rigging (cranes, rigging, warehousing); Marr Scaffolding Company (scaffold, shoring, mast climbers, power equipment and bleachers) and Isaac Blair, a specialty heavy-duty shoring company providing emergency services. For the purposes of this presentation, Marr will focus on steel erection services, shoring and specialty shoring to include: Historical Facades, Foundation Failure, Building Remediation, Foundation Failure, Needle Shoring, Roof Truss Failure, Masonry Failure, Calibrated Jacking, Column Replacement and Emergency Services.

Diego S. Arabbo, PE
Senior Project Manager | Simpson, Gumpertz & Heger
Diego Arabbo has extensive experience designing, investigating, and rehabilitating structures of all types. He has participated in the design of complex industrial buildings, process and motor control buildings, commercial buildings, pedestrian and vehicular bridges, retaining walls, and foundations. His design experience also extends to construction engineering and includes the design of temporary shoring, bracing, and support of excavation.
|
|
|
Diego has either led or played a prominent role in the investigation of failed retaining walls, of a steel building that collapsed during erection, of a steel building that experienced excessive movement during erection, of floor arches that partially collapsed during demolition, and of a power pole that collapsed during service. As part of his experience in structural rehabilitation, he has performed condition assessments and strength evaluations of buildings, bridges, tunnels, foundation elements, and retaining walls, and has designed repairs and strengthening measures for steel trusses, steel and concrete structures, and foundation elements. He has also provided full-time on-site technical supervision during rehabilitation of tunnel and bridge projects. |
