Learn how to place and finish concrete using ready-mixed supply, pumps, vibrators, and formwork coordination. Understand concrete types, strengths, curing, and hot and cold weather practices.

Estimate concrete costs by calculating in place concrete volumes for slabs, columns, and beams, then validate line-item costs with supplier pricing, finishes, additives, and testing considerations.

Assess structural works by validating foundations, formwork, reinforcement, and concrete costs; compare unit costs per area and volume to past projects, and recheck for errors.

Learn to estimate building enclosures by analyzing exterior walls, roofs, curtain walls, and flashing, detailing water, air, vapor, and thermal control layers, and aligning with master format for cost takeoffs.

Gain practical guidance on building envelope and roof quantity takeoffs using Revit drawings, identifying glazing, brick walls, and materials, and estimating by square foot and linear measures across elevations.

Estimate the costs for roof and building envelope elements, including vapor barriers, insulation, membranes, parapets, flashing, glazing, curtain walls, doors, windows, skylights, caulking, and scaffolding.

Explore interior construction systems and material estimation through master format classification, focusing on doors, walls, and finishes. Learn to perform quantity takeoffs for doors, hardware, drywall layers, and demising walls.

Perform a quantity take-off for interior construction systems, measuring walls, doors, drywall, and glass walls; do not deduct door openings, and account for exterior drywall behind curtain walls.

Master pricing interior construction systems by performing take-offs for doors, hardware, service doors and closers, then estimating drywall, metal studs, insulation, and finishes with waste factors and door sizes.

Explore interior finishes such as wood, carpet, and ceramic tiles, and learn wood types birch, cherry, and walnut, plus installation methods for solid and engineered wood and tile setting steps.

Perform quantity takeoffs for ceilings, floors, and walls across service, circulation, instruction, and administration areas. Price finishes like acoustic tiles, vinyl, carpet, ceramic tiles, epoxy flooring, drywall, and painting.

Identify and price division 10 building specialties, including visual displays, signage, toilets and partitions, lockers, fire protection, and protective details, and learn how to include them in takeoffs and estimates.

Master quantity takeoffs and pricing for stairs and railings by counting risers and landings, selecting materials (wood, metal, concrete), and pricing rails, including outdoor galvanized finishes and cast-in-place concrete considerations.

Learn to estimate cabinetry by identifying base and wall cabinets, countertops, and materials like laminate, marble, granite, and quartz. Compare per cabinet and per linear foot pricing using cost book.

Learn about building services, including conveyance systems, plumbing, electrical, fire protection, and drainage, and how their scope shapes estimates, including detailed takeoffs and top-down or parametric costing.
