A crew for JB Concrete Foundations forms and pours the stemwall foundation for a 4-unit apartment building on an infill site in the East End of Portland, Maine.
This iPhone panorama photo of the site gives an idea of the lot dimensions. Tight setbacks and a deep lot add some wrinkles to the construction problem.
A pump truck supplied by Northeast Concrete Pumping (Scarborough, Maine) in place by the curb at the jobsite. Parking and traffic control are part of the problem project manager Jeff Barker has to solve.
The crew pours a stiff mix, with a four-inch to five-inch slump. Shovel work is part of the process.
While the pump truck operator controls the flow of concrete with a remote control, concrete masons direct the mix into the forms and consolidate the concrete with a mechanical vibrator.
