Detailed design (EXE): what goes into a set of formwork and reinforcement drawings?
Formwork drawings, reinforcement drawings, bar schedules and calculation notes: what a detailed design package contains and what to check before issue.
ROKENG supports construction companies and engineering firms: structural calculations, geotechnical and retaining structures, EXE drawings, quantity surveying and BIM.
