The Job
This NYC cellular concrete project is located at the William McCray Playground in Manhattan. The existing playground had experienced significant subsidence, which damaged the already outdated equipment.
The entire playground was demolished, in order to install a new updated facility, including play equipment, basketball court and spray equipment.
The Challenge
Design documents called for three feet of 25lb/cuft lightweight fill material over roughly 4,000 square feet of the site. Two options were given to contractors; 25lb/cuft cellular concrete or foamed glass aggregate.
Logistics for any work in Manhattan are tricky. Challenges include truck traffic limitations, constraints on work time and noise, and the narrow, congested streets. There was no room on the site for any stockpiles.
The Solution
The customer determined using 25lb/cuft CJFill-Ultra Lightweight fill by CJGeo would be the lowest risk, most economical, and fastest method allowable by specification. Because the equipment for generating foamed concrete fill is mobile and compact, the tight site wasn’t a problem.
CJGeo brought in just four loads of cement in order to generate the approximately 550 cubic yards of foamed concrete material. Cold temperatures didn’t affect the operation; it froze the night between the two pours, and also the night afterwards. No tenting or protection is required.
The day following the second pour, the customer was able to start placing pavement base on top of the cellular concrete.
