Terra-Petra is excited to be involved with the construction of a project for an organization called “Family House – (aka The Nancy and Stephen Grand Family House) in San Francisco, California. The not-for-profit organization offers free-of-charge housing for qualifying families of seriously ill children receiving treatment at University of California San Francisco Benioff Children’s Hospital. The project site is near the new site of the hospital in the Mission Bay area of San Francisco. The move in for the development is projected for November 30, 2015.

The soil gas and waterproofing system, two separate mobilizations, took just 5 days to install and covered 30,000 square feet. This efficient installation had little to no impact on the overall construction schedule which made the architect, owner and general contractor extremely satisfied. The link below is a time-lapse video, where the two phases of Terra-Petra’s involvement with this remarkable project include the entire foundation being covered in green and then with black layers of coating. The section of the video where the green layer is applied shows the VI-20 base layer of the membrane sandwich while the black layers are both the spray-applied Liquid Boot membrane and the geotextile protection course.

The system was designed to take care of three separate compliance matters: the corrosive soil requirements, waterproofing site specific design issues, as well as the Maher Ordinance, which is enforced by the San Francisco Public Health Department.  Terra-Petra provided a single source manufacturer to address all three issues efficiently and effectively.

More about Family House: Qualifying families that live more than 50 miles away and prior to 1981 had to take part in a nightly lottery to get a mat to sleep on the floor of a UCSF conference room. If they could not get in, many would sleep in their cars or pay for costly hotel rooms nearby. This inconvenience and sometimes financial burden would only add to the stress of dealing with home and work coverage, sibling care, transportation issues, pet care, changing appointments and so on, all at the same time as dealing with the emotional difficulties of having a child with a serious illness. In 1981, Dr. Arthur Albin and his wife, Debbie, co-founded the first Family House which housed 10 families per night.  A second house opened in 2002 to house 24 more families—all free of charge.  Today, over 2,000 families are served.  After the opening of this new project in Mission Bay, with which Terra-Petra is proud to be involved, another 200 units will be added.
