LENDLEASE DRIVES SUSTAINABILITY IN CONSTRUCTION

6 Mar 2018

As one of the leading construction players in the United States, Lendlease works with clients to deliver sustainable projects. Around the world, Lendlease is striving to reduce energy usage, water consumption, and waste by 20 percent of its 2014 Baseline by 2020 and overall is implementing sustainable practices at project sites to drive environmental efficiency across the company’s four regions. Whether it’s energy efficiency in temporary lighting and heating or construction and demolition waste management or activity pollution prevention, Lendlease’s sustainability practices are helping clients meet ambitious green building objectives, including achieving LEED certification.

Take Lendlease’s Columbia Manhattanville project, for example. Lendlease recently delivered two prominent buildings for Columbia University on its Manhattanville Campus: the Jerome L. Greene Science Center and the Lenfest Center for the Arts. In total, the buildings provide the school with more than 510,000 square feet of research labs and performing arts space. Designed by Renzo Piano Building Workshop and Davis Brody Bond as the architect of record, the project has won multiple awards for its quality of design and impressive construction metrics. In coordination with accomplished design and construction teams, Lendlease had the opportunity to pilot innovations and showcase sustainable building techniques.

WATER REDUCTION

To reduce potable water use on-site, the team installed a ground water collection system, which was then used for truck wheel washing. This reused water contributed to the company’s potable water reduction goals and helped to raise awareness about opportunities to reuse rainwater on construction sites.

CLEAN CONSTRUCTION

 

Columbia University developed Clean Construction Requirements and Lendlease guided revisions to meet construction requirements. In collaboration with Columbia University, and oversight by a City Monitor, Lendlease enforced these requirements on many aspects of the project, including Construction Waste Management; Dust Control; Emissions Control; Erosion and Sedimentation Control; Noise Control; and Vector Control. To verify that measures were continually met during construction activities, the City Monitor conducted monthly walk-throughs and provided suggestions for corrective measures, which the Lendlease team addressed immediately. The construction team also produced a daily report that outlined each day’s activities that could impact Clean Construction operations.

 

 

WASTE REDUCTION

Wallboard scrap from construction sites is typically sent to landfill or agricultural amendment, but this project participated in a pilot initiative to close the loop on wallboard waste by recycling wallboard scrap into new gypsum products. The project transported approximately 60 tons of wallboard scrap to USA Gypsum in 2015. This strategy contributed to the project’s total approximate 91% landfill diversion rate, supporting Lendlease’s commitment to waste reduction and helping the project achieve LEED Certification. 

 


LEED GOLD CERTIFICATION

 

Throughout the duration of the project, Lendlease participated in an integrated effort to achieve this exceptional LEED Certification rating. In collaboration with the Sustainability Consultant, Design Team, and Owner, Lendlease procured compliant materials, documented the progress towards approximately 30% recycled and 15% regional material content, and minimized material VOC content.  Lendlease tracked submittals and worked with the Sustainability Consultant to ensure compliance. Upon building completion, the team helped to perform extensive indoor air quality testing and flush-outs of the new HVAC system. 

 

The construction of the two buildings on the new Columbia Manhattanville campus showcased Lendlease’s commitment to sustainability and employed innovative construction strategies that made it a challenging, educational, and rewarding project. Lendlease is pursuing similar strategies on future projects and will continue to identify opportunities to achieve the most sustainable results possible.
