Modular construction has been heralded by many as the next big thing in building structures quickly and cost effectively. By being able to construct parts of the building in a controlled environment, like a factory, workers can perform more efficiently, comfortably, and safely, ideally translating into shorter schedules and smaller costs. That theory got one of its biggest tests on a new 32-story residential building that recently opened in Brooklyn, NY.
461 Dean Street, being heralded as the world’s tallest modular building, is a 363-unit residential tower located directly adjacent to the Barclays Center in Brooklyn. Designed by SHoP Architects, the tower design was expected to reduce construction costs by 20% and trim 10 months off of the proposed 30 month schedule, according to City Limits. Each modular section, of which there were 930, were built at a new factory at the Brooklyn Navy Yard and shipped to the site in a 10 foot high by 15 foot wide by 30 foot long chassis. The groundbreaking ceremony took place in December of 2012 and the building was scheduled to be completed by the end of 2014.
Unfortunately, things didn’t quite go as smoothly as everyone was hoping. For the past 4 years, the project has been plagued by delays, lawsuits, alleged design and construction issues, and water damage. According to documents obtained by City Limits, half of the first 39 apartments suffered “significant water damage,” which then lead to accusations from both the builder, Skanska, and the designer that the other was at fault. In the summer of 2014 reports surfaced that floors 2 through 8 all “suffered extreme water damage.” The damage caused considerable on-site rework, some mold growth, and additional delays. At one point, the factory left off some of the drywall of the new units, in fear that more water damage would occur. Other reports showed that the modular units were misaligned, even causing loose façade panels to visibly flap against the side of the structure. In September of 2014, Skanska closed the Navy Yard factory down, after the developer, Forest City, refused to pay additional costs for delays and other design problems, according to reports. You can read Skanska's 146 page contract termination letter here.
In January of 2015, around 4 months after the factory closing, Forest City reopened the factory and began building the modules again. In May of 2016, the tower’s final modular unit was set into place, according to Curbed. Though the schedule took around twice as long as originally planned and media outlets have projected budget overages of millions of dollars, the building is almost ready to welcome its firs residents.
As of November, leasing options are available for potential residents and media members were able to tour the new building. You can check out a virtual tower of some units, put together by Inhabitant, below this article. Many of the units boasts some impressive views of both the city skyline and the Barclays Center green roof.
Through it all, the 32-story building still managed to open and currently have apartments available for lease. Although your company should be counting its blessings that they didn’t have to be involved with this project, this isn’t a story that should discourage modular construction from continuing in the future. Though modular construction has been talked about for a long time, it’s still a fairly new concept in implementation, especially on the level of 461 Dean Street. Contractors, developers, and designers alike can use this project as a learning experience for additional modular buildings. As the concept becomes more commonplace, we should expect project timelines and costs to shrink considerably.

Many could argue that peanut butter and jelly or spaghetti and meat balls go together about as well as cursing and construction job site. Sometimes I find myself surprised that there are more curse words written into construction proposals.
Originally set to be enforced on June 23, 2017, the Occupational Safety and Health Administration new rule regarding silica dust exposure limits has been delayed an additional 90 days, to September 23, 2017. Many construction industry groups were upset by the new rule, as they deemed it “technologically and economically infeasible, but also unnecessary.”
Scissor lifts are on most typical construction job sites and they’re an often overlooked hazard. Too often, liberties are taken with the lifts that create unsafe conditions, which can cause injuries and deaths. OSHA recently released the results of their investigation of 10 fatalities and 20 injuries involving scissor lifts and released their findings in what the organization refers to as a “Hazard Alert.”
There’s no doubt that bridge demolitions by implosion are extremely fun to watch, but the fireworks show and big splash into the water below can sometimes overshadow other demolition projects that don’t allow implosion. Priestly Demolition Inc. (PDI) recently won two 2016 World Demolition Awards for one of those projects where implosion was not an option and they have also produced an incredibly detailed video of how they did it.
As of the first quarter of 2016, the Bureau of Labor Statistics (BLS) reports that there are over 768,000 construction companies currently operating in the private industry in America. There are also countless more that have come and gone. According to Statistic Brain, only 47% of construction startup businesses are still operating after year 4. Personally, I've seen many people break off from a construction company and create their own business; some are still in operation, others have failed.
Try to imagine .0015 inches, it’s not easy to visualize. Now, rip one of the hairs off of your head and that’s about half of the .0015 inches, which is the allowable variance of a concrete floor that one contractor is working on right now.
Augmented reality on construction job sites has been a focus of several technology companies in recent years. As of now the clear leaders in the category have been the DAQRI smart helmet and glasses and the MIcrosoft Hololens. Early this year, DAQRI introduced their new smart glasses, which are the lighter and more mobile version of their fully protective smart hard hat. The new DAQRI product is a clear competitor for Microsoft’s Hololens, which is also a smart headset product. Backed by the powerful construction technology company Trimble and in a partnership with the University of Cambridge, the Hololens is getting tested with 2 new concepts specifically for the construction industry: Automated Progress Monitoring and Automated Bridge Damage Detection.
The following is a guest post from Kari at Appfluence, maker of Priority Matrix, a priority management solution that helps construction teams execute more effectively, by centralizing project information and enhancing communication.
As a manager, it’s not uncommon to ask yourself, ‘am I doing this right?’ Even the most experienced managers in the construction industry consistently strive to learn different methods of management that allow them to increase their team efficiency and deliver more successful projects.
An acquisition of Interline, a home repair and maintenance products firm, and a 2 year trial run of delivery services has positioned The Home Depot (THD) to begin offering same day deliveries for professionals.
Adding more space to premises, be it a domestic property or another premises such as a clinic, school or college, comes at a price.
It is expensive to have the building designed and built, especially using traditional methods. There are is also the question of disruption with contractors on site.
There is a viable alternative: modular construction.
