Digital Design, Coordination and Delivery

Methods for digital design, coordination, and delivery are prevalent in the building design and construction industry. As tools and knowledge evolve, new software applications present themselves on a broad range of projects. Modeling software is especially relevant to structural designers, who can use the software to optimize material quantities, improve coordination, and streamline execution for project with complex geometry.

To Repair or Replace: Structural Assessment of Damage at the Steeplechase Pier

By: Kirk Stauffer, Steven Hall, Kevin Poulin
Steeplechase Pier, located in Coney Island, Brooklyn, was damaged by Hurricane Sandy in late 2012. During reconstruction of the pier in 2013, the mooring “spud” of a construction barge failed and the barge rammed into the pier, seriously damaging it. Their article outlines the response to investigate this damage and develop repairs, details the challenges of completing an investigation that determined the condition of the piles, and discusses how the aggressive schedule to reopen the pier ultimately determined the chosen repair scheme.

Facade Inspection and Maintenance

A well-designed, constructed, and maintained building facade protects the building interior from water leakage, air infiltration, and energy loss. However, environmental exposure and time can degrade facade components. Facade deterioration can lead to a range of issues from compromised performance to potential falling hazards.

Building Facades: San Francisco Inspection Requirements

​Damaged and deteriorated building facades are a serious public safety concern. The damage also affects the appearance and structure of buildings playing significant roles in San Francisco’s culture and history. When facade elements fail, there is a chance the component could fall — putting people and property at risk. As a result, many cities, including Boston, Chicago, and New York, have adopted facade ordinances.
