This is one of our current projects. A Detached workshop with a 5 1/2″ thick mono slab to accommodate heavy tools. This project suffered a one week delay to have the forms verified by the surveyor. The setbacks were hard to define at the site because of their obscure location up behind block walls. The pins were set 4 weeks earlier but the form elevation to finished floor and the building line precise location needed to be documented for the city planning department records.
