Concrete Cost Estimating

Learn to estimate concrete construction costs from drawings and specifications by understanding concrete types, mix design, reinforcement, joints, and the full build sequence from pre works to post pour finishing.

Identify mandatory pre works, ground preparation, utilities survey, and scaffold setup to enable the FRP process for formwork and pouring, with drawings alignment and concrete testing.

Understand formwork as the temporary mould that supports and shapes freshly poured concrete until it gains sufficient strength, using timber, plywood, steel, aluminium, or plastic.

Explore how steel reinforcement, including rebars, welded wire mesh, and fiber reinforced polymer, enhances concrete's tensile strength, durability, and load capacity through traditional, prefabricated, and post-tensioning methods.

Master pre-pour inspections and proper consolidation to ensure structural integrity and consistent curing. Explore concrete placement methods, including ready-mixed delivery, pumping, chute pouring, kibble, wheelbarrow, tremie, and SCC.

Learn how to cure and protect concrete by maintaining moisture for proper cement hydration, using water, membrane, or steam curing, and applying temperature and weather protection for strength and durability.

Learn finishing techniques and surface treatments to improve the appearance, texture, and durability of concrete, including screeding, troweling, broom finish, stamping, curing compounds, sealers, and polished concrete surfaces.

Section two on measurement identifies the key quantities driving site preparation, formwork reinforcement, concrete placement, curing and protection, and finishing and surface treatments, and how to measure them.

Identify and measure the underlying quantities that drive cost, then apply unit rates to estimate item costs. Learn how quantity times unit rate yields concrete, formwork, and rebar costs.

Identify site preparation before concrete works and read the contract to understand the quoted scope. Estimate excavation, backfill, services, surveys, and measure clearing, grubbing, and slab volumes for accurate costs.

Estimate formwork quantities by structure type, calculating square meters for slabs, walls, and joints, and apply 15% wastage while noting design requirements for temporary works.

Estimate steel reinforcement by weight or volume using ratio or volume methods, from drawings for walls, slabs, and piers, to determine total reinforcement.

Master concrete placement by calculating structure-wise volumes and the number of pours, considering formwork, steel fixing, batching, site logistics, and curing to estimate total costs.

Calculate key quantities for curing and surface treatments by measuring slab surface area, saw-cut lengths, exposed aggregate areas, and patching surfaces after formwork removal.

Learn to convert activity quantities into material, labor, and plant costs using sample figures, covering resources, duration, site preparation, formwork reinforcement, concrete placement and curing, and surface treatments.

Identify resources for each task, calculate material costs by volume and unit rates, and apply labor, plant, and subcontract pricing using daily production or man hours method.

Turn site preparation quantities into a final cost within concrete cost estimating by calculating ground preparation, utilities survey, and access needs, detailing membranes and rock-base materials.

Estimate formwork costs by calculating materials and labour per square meter, applying pro rata rates for strip footings and walls, and using productivity rates for beams, walls, and joints.

Explore steel fixing for concrete cost estimation, covering reinforcement materials (bars, mesh, dowel bars, bar chairs, welding), prefabricated cages, and labor productivity calculations using hours per ton and rates.

Estimate concrete placement costs by applying quantities, production rates, and fixed equipment costs, accounting for labor, pumps, and pour-specific productivity for slabs and walls.

Estimate curing and surface treatments for exposed aggregate, including curing compounds, sealant, grout, hole patching, and saw cutting, then convert quantities into cost estimates with labor hours and per-meter rates.

Explore indirect costs, risk, opportunity, and subcontracting in concrete construction estimates, building on direct items like site prep, formwork, reinforcement, placement, curing, and surface treatments.

Identify and quantify indirect costs, both non-recurring and recurring, such as material handling equipment, safety, on-site facilities, waste management, surveying and site measurement, and outline methods to estimate project duration.

Identify and quantify risks and opportunities to build a contingency in concrete cost estimates, using likelihood, impact, and contract alignment to safeguard profitability.

Price concrete works with turnkey subcontractors, weighing advantages and disadvantages for the contractor, and use a scope of work with three quotes to inform non lump sum or resource-based contracts.

Explore practical cost estimating for small concrete projects by reviewing design, measuring quantities, calculating direct costs, and adding indirect costs, risk, and opportunity before presenting to a client.

Apply concrete cost estimating by reviewing scope, drawings, and quantities; calculate direct costs, indirect costs, risk, and opportunity for a lump-sum quote on six piers and two generator slabs.

Review drawings and measure key quantities to drive direct costs for board piers and generator slabs, including survey hours, excavation, formwork, reinforcement, and concrete with 15% wastage.

Turn project quantities into direct costs using assumed rates, detailing survey, excavation, formwork, reinforcements, concrete pours, and total direct costs for generator pads.

Calculate indirect costs, risk and opportunity, and corporate overheads to adjust direct costs, apply profit margin, and derive the sale price for submission to the client.

Turn drawings into quantities and apply resources and rates to estimate costs, converting drawings into dollar figures and highlighting the high demand for quantity surveyors.
