Acceptable Tolerances for Residential Footings
Concrete Foundations Association (CFA)
This column pertains to the nature of minimum requirements or specifications for the size of concrete footings in relation to the foundation walls they support.
August 14, 2017
Chalk lines on the footing designate the inner formwork wall line. The width of the footing minus the wall thickness should leave enough footing along the outside to support the wall forms.

One City Center
MEVA systems working together save time on this inner city job site, and MEVA’s Guided Climbing MGC system makes its North American debut.
August 14, 2017
Each MGC unit remains attached to the structure even during lifting thanks to its two guiding profiles. The wall formwork is placed on and attached to the platform. It can be retracted for rebar work and for the climbing process. The MGC unit and the wall formwork are lifted as one single unit. The platforms can be equipped with standard frailings and also with a mesh. Ladders and safety cages ensure safe access to the platforms.

Approach Form Camber Specifications with Caution
American Society of Concrete Contractors (ASCC)
Cast-in-place reinforced concrete structural members deflect under load. Whatever the cause of the problem, engineers have sometimes tried to control deflection effects by requiring cambered form soffits.
August 14, 2017
Ideally, a cambered cast-in-place slab deflects just enough to take out the camber and result in a uniform-thickness slab with the surface at the design elevation. That rarely happens.
