Pr3ciseConcrete and masonry estimating services in Miami
Foundations, slabs, CMU, formwork and reinforcing measured to the assembly — the structural backbone of almost every South Florida building, and the trade where HVHZ costs the most.
Bring in a concrete cost estimator for the package you are bidding: concrete measured by pour and by element — footings, slabs, columns, beams, shear walls — with formwork, reinforcement and finishing quantified separately, and masonry counted by unit type with grout and reinforcing broken out. It is one trade inside our construction estimating service for Miami-Dade, and the one where a local number and a national number diverge fastest.
Every project inside Miami-Dade sits in the High-Velocity Hurricane Zone, which drives reinforcement density, tie-down and connection detailing, and the inspection holds that shape your pour schedule. Below the slab, oolitic limestone and a shallow water table do the rest.
What a Miami concrete contractor gets in the estimate
- Foundations and footings: excavation, forming, reinforcing, concrete by mix design and placement method, with pile caps and grade beams where they apply.
- Slabs on grade and elevated, including vapor barrier, mesh or rebar, finishing, curing and joint treatment — and post-tensioned decks where the structure calls for them.
- CMU walls quantified by block size and type, with cells to be filled counted rather than averaged, plus mortar, grout, reinforcing, lintels and bond beams.
- Tie beams and columns — the poured elements that tie a South Florida masonry building together and carry its wind resistance.
- Formwork priced by contact area and reuse cycles rather than as a percentage of concrete cost, which is how form-heavy jobs get underbid.
- Reinforcing steel quantified by bar size and weight, with laps, chairs, ties, dowels and accessories included instead of assumed.
- Site conditions that belong to the structure: rock excavation, dewatering, compaction and the access a crane or pump truck needs.
Units that decide a concrete number: yards, contact area and pounds
A structural package is only as good as its units. Concrete goes in by cubic yard, split by mix design and by how it is placed, because a pumped pour and a direct-chute pour are different money for the same yardage. Formwork goes in by square foot of contact area with a stated number of reuses. Reinforcing goes in by weight per bar size, with laps, chairs and ties counted. Masonry goes in by unit, by size and type, with filled cells counted off the structural drawings and grout carried as its own volume. Finishing, curing and joint treatment are measured by area and length, excavation and backfill by volume, and embeds, anchors and dowels by each.
What you receive is an Excel workbook and a PDF organized to CSI Divisions 03 and 04, with material, labor and equipment separated, waste factors stated per material rather than a blanket percentage, and the marked-up drawings so every quantity traces back to the element it came from. Assumptions and exclusions are written out — rock quantities beyond the geotechnical report, dewatering duration, testing and inspection fees, and any structural scope the drawings defer to a delegated engineer. The format is visible in our sample estimates.
Six ways a concrete and masonry takeoff loses money
- Formwork as a percentage of concrete. The classic. A slender column or a stepped footing has enormous contact area for very little volume, and the percentage method underbids it every time.
- Filled cells assumed rather than counted. In the HVHZ the proportion of filled cells is high and varies wall by wall. An assumed percentage is a coin toss on the biggest masonry cost driver.
- Rebar without the accessories. Laps, chairs, ties, bolsters and dowels are individually trivial and collectively tons of steel on a large pour.
- Rock priced as soil. South Florida limestone is not the dig most national databases assume, and the productivity difference shows up in every trench and footing.
- No allowance for the water. Where groundwater is shallow, footings and below-grade work need dewatering that a template will not include and a site superintendent cannot avoid.
- Openings handled sloppily. Deducting openings without adding back lintels, jambs, bond beams and the extra reinforcing around them turns a saving into a shortfall.
None of these show up as an obvious error on bid day — they show up as a thin margin six months later, which is the pattern described in seven ways to ruin a construction project.
Four steps from structural drawings to a priced package
Drawings in
Structural and architectural drawings, the specification, the geotechnical report if there is one, any addenda and the bid date. The soils report matters here more than on any other trade.
Takeoff
Elements measured one by one and colour-marked: footings, slabs, columns, beams, walls. Volumes, contact areas, bar weights and block counts kept separate, with filled cells counted off the structural sheets.
Pricing
South Florida ready-mix, block, steel and labor rates cross-checked against supplier quotes, with placement method, crane or pump access, rock and dewatering priced as real line items.
Delivery
Excel and PDF with the marked-up drawings, typically in 24 to 72 hours. Markups adjust to your numbers, and a structural revision is repriced section by section rather than patched into the total.
HVHZ, rock and water: what Miami-Dade does to the structure
- HVHZ reinforcing density. Wind resistance in Miami-Dade means more filled cells, heavier tie beams and more reinforcing than the same building elsewhere in Florida. This is the single largest HVHZ cost driver on a masonry structure.
- Approved anchors and connectors. Straps, anchors and adhesive systems used in the zone carry product approvals, and a Notice of Acceptance names the product. Substituting a cheaper equivalent is not a pricing decision here — it is a permitting problem.
- Oolitic limestone excavation. South Florida rock is harder to dig than the soils most national cost databases assume, and it changes both productivity and equipment selection.
- High water table. Shallow groundwater across much of Miami-Dade frequently means dewatering for footings and any below-grade work, priced by duration rather than forgotten.
- Concrete durability near the coast. Chloride exposure drives mix design, cover requirements and sometimes corrosion-inhibiting admixtures, none of which are free.
- Recertification repair work. Structural concrete restoration driven by Miami-Dade recertification and Florida milestone inspections is a large and distinct market, priced very differently from new construction, and often with a special inspector in the loop.
Concrete and masonry work we price across Miami-Dade
The structure changes with the postcode. Homestead, Kendall and Cutler Bay are slab-on-grade and block-and-tie-beam work, where rock excavation and filled-cell counts dominate. Doral and Medley warehousing is tilt-up and heavy slab, priced on panel area, embeds and crane time. Brickell, Downtown and Aventura towers are cast-in-place cores and elevated decks, where formwork cycles and pump access decide the number. Coral Gables and Pinecrest residential is CMU with architectural finishes attached. Miami Beach and Key Biscayne bring the coastal restoration work — balcony, spall and post-tension repair driven by recertification — and Hialeah adds older industrial masonry with existing conditions nobody drew. Broward projects in Fort Lauderdale and Hollywood price the same way.
Permitting and structural inspection run through Miami-Dade County in unincorporated areas and through each municipal building department elsewhere, with threshold work carrying its own inspection regime. Concrete rarely finishes the job on its own: where the package continues into services, the plumbing estimate covers the underground that goes in before your slab, and the MEP estimate covers the sleeves and embeds the structure has to carry.
Concrete and masonry estimating FAQs
Yes. Filled-cell counts come off the structural drawings rather than an assumed percentage. In the HVHZ that count is high, it varies wall by wall, and getting it wrong moves the number substantially.
By contact area with an assumed reuse cycle, both stated in the estimate. Pricing formwork as a percentage of concrete cost is the most common reason form-heavy jobs get underbid — a slender column has very little volume and a great deal of form.
Structural and architectural drawings, the specification, any addenda and the bid date. The geotechnical report matters more here than on any other trade: rock, groundwater and bearing conditions decide excavation productivity and whether dewatering belongs in the number.
Yes, as their own line items. South Florida oolitic limestone is not the soft dig national cost databases assume, and much of Miami-Dade has a water table shallow enough to need dewatering for footings and below-grade work. Where the soils report does not settle it, we price a stated assumption and flag the risk.
Yes, and it is a significant part of our Miami work. We price directly from the engineer inspection report, itemized by repair type and quantity so an association or owner can see what each line costs.
Yes. Bar size, weight, laps, chairs, ties, dowels and accessories are all included. Accessories are small individually and add up to real money on a large pour.
