Quantity Takeoff and Estimating I
Measuring work from drawings and building unit-price estimates: estimate types and AACE classes, MasterFormat, UniFormat and the CIQS elemental format, measurement rules, takeoff workflow and digital takeoff, loaded labour rates with CPP, EI and workers' compensation, equipment owning and operating costs, material quotes, waste, escalation and GST, HST and PST, and takeoff of earthwork, concrete, masonry, wood framing, structural steel and finishes, ending in a capstone unit-price estimate.

What you'll learn
- Describe who prepares estimates on a project, the kinds of estimates prepared as design develops, and the AACE estimate classes and their indicative accuracy ranges
- Prepare conceptual estimates from cost per unit of floor area, adjusted for time, location, size and quality, and state their range
- Organize estimates using MasterFormat, UniFormat and the CIQS Elemental Cost Analysis format, apply measurement rules and set up cost codes
- Plan and carry out quantity takeoff by count, length, area and volume, on paper and digital drawings, and check quantities by independent methods
- Build loaded labour rates including CPP, EI, workers' compensation, vacation pay and benefits, and price labour from crews and productivity rates
- Calculate equipment owning and operating costs, compare renting with owning, and price work from equipment production rates
- Price materials from levelled quotations with waste, delivery, escalation and the correct treatment of GST, HST, QST and provincial sales tax
- Take off clearing, stripping, cut and fill, building excavation and trenches, and convert between bank, loose and compacted volumes
- Take off concrete volume, formwork contact area, reinforcing and finishing for footings, walls, slabs and other elements
- Take off masonry units, mortar, grout, reinforcement and accessories for concrete block and brick veneer walls
- Take off wood framing, sheathing and structural steel, convert lumber to board feet and steel to tonnage, and identify separate items
- Take off finishes, doors and hardware from schedules, use estimating software and BIM quantities critically, and assemble a unit-price estimate
