This document provides instructions for defining and assigning trade categories and trades in a housekeeping menu in order to generate bills of quantities (BOQs) and cost estimates. It describes how to: 1) Add trade categories like wood, doors, and furniture. 2) Define basic trades like frames and leaves for doors using predefined material, labor, and equipment codes. 3) Create door trades by copying from basic trades and combining multiple trades while avoiding duplicate resource phases. 4) Access the costing function to select a project and BOQ, assign predefined trades to lines, modify resource quantities, and view unit and total costs.
