An elevated slab is the one place in a Midland building where the concrete schedule and the structural schedule are the same document. Every deck we pour sits on formwork and shoring that has to come out in a set order, and the next floor cannot start until the one below has the strength the engineer wants to see. That is why we ask for the framing sequence and the owner's move-in date before we talk about price.
We place and finish suspended slabs, composite metal-deck pours, flat plates, beam-and-slab floors and parking-structure decks for general contractors, developers and institutional owners. Typical jobs are the upper floors of a spec office near Loop 250, a hospital wing, a college building or a parking deck beside a downtown tower. The work is vertical, but the planning is mostly horizontal: trucks, pumps, crews and cure time laid out on a calendar.
The sections below describe how we handle the decisions that move the cost and the date on elevated work in this market.
What we look at before a deck is priced
Deck type drives almost everything. A composite slab on metal deck carries its own pour sequence and edge details, while a conventional formed slab needs full shoring and a longer wait before stripping. Post-tensioned decks add stressing windows and tendon layout that the pour has to respect. We read the structural drawings for span, thickness, camber and embedded items before anything else, then compare them to what the framing contractor plans to deliver.
Access matters as much as design. We check where the pump will stand, how far the boom must reach, whether the street can hold a truck line, and where wash-out goes. On tight downtown lots the pump position sometimes decides the pour size. If the slab has to be split into more placements than the drawings assume, we say so in the proposal, not after the first pour.
Specifications, special inspection and the permit office
Elevated slabs are inspected more closely than anything poured on grade. The structural set normally calls for reinforcement inspection before each placement, cylinder or cube sampling during the pour, and documented review of shoring and reshoring plans. We build the pour around those hold points so the inspector is on site at the right hour, and we keep the paperwork organized so a missed signature never stops a deck from being released.
Formwork design, concrete strength at stripping and any post-tensioning submittals follow the project specification and the adopted building code. Where the local permit office requires a separate review for a structure such as a parking deck, we allow time for it on the calendar. We would rather raise a question during submittal than discuss it with an inspector standing on a finished floor.
Pour calendars, haul time and reshoring
Midland owners rarely want a deck schedule that depends on luck, so we write one. The calendar shows each placement, the days the mix plant needs to reserve volume, the earliest strip date for each bay and the point where reshoring moves up. Ready-mix haul time is a real input. A long delivery in summer heat changes slump and set, so we agree with the supplier on batch timing and truck spacing before the pour, not on the morning of it.
We also plan for the floors above. A properly reshored deck can carry construction loads sooner, but only when the engineer has approved the scheme, and that approval belongs on the calendar next to the pour dates. When the owner's operating schedule is fixed, for instance a clinic that has to open in a given month, we work backward from that date and tell the general contractor which pours leave no slack.
Why decks cluster along a few corridors
Loop 250 is a 12.245 mile bypass of northern Midland, and its west end meets I-20, SH 158 and SH 349. That junction pulls spec offices, medical buildings and retail pads to the north and west, and the multistory ones need elevated floors. Along the west side of the city, the route of SH 349 reaches Loop 40, which leads to Midland International Air and Space Port, where terminal and hangar work around the airport area brings its own suspended and apron slabs.
The airport was approved as a spaceport on September 17, 2014, the first primary commercial service airport to receive that certification. Owners in that area often stage construction around active airfield operations, which affects crane swing, truck routing and pour hours. We plan those limits into the calendar and confirm them with the owner's representative before mobilization.
Concrete scope and preparatory work
Deck placement is organized around edge forms, screeding, finishing and curing, with the concrete specialists coordinating those operations and the subsequent stripping sequence. We bring in specialty trade partners for work outside that scope, such as post-tensioning stressing, shoring engineering and rental, pumping fleets and testing. We coordinate those partners under one schedule so the general contractor deals with a single point of contact on the deck.
That split is deliberate. A pump operator who works every week has a better sense of boom reach than a crew that rents one twice a year, and a post-tensioning specialist carries the equipment and certifications the work needs. Our role is to keep the pieces in sequence and to make sure the concrete is ready when they are.
Our method on a suspended slab
We start with a pre-pour meeting that includes the general contractor, the engineer's inspector, the pump supplier and the batch plant dispatcher. Each person leaves with a copy of the sequence, the headcount and the contact numbers for pour day. We walk the deck, count the chairs and bolsters, check the embeds against the drawings and confirm that the forms and shoring match the approved plan.
During the pour, one foreman owns the placement sequence and another owns finishing and cure. Concrete is placed in lifts that the screed crew can keep up with, and curing starts as soon as the surface allows. In Midland's dry air, that usually means early moisture retention, since a deck loses water from the top faster than most people expect.
Working at height and under load
Elevated pours put people at an open edge and put heavy loads over occupied or soon-to-be-occupied space. We require edge protection, fall protection and control of the area below the pour before concrete moves. Rebar and conduit crews are coordinated so nobody works under an active placement, and formwork is inspected before crews step on it.
We also review the weather plan. High wind in the early spring and summer can shift pump booms and blow debris onto a pour, and Howard County's dust storms remind everyone that this country has real weather. If conditions pass the limits we set with the pump company, we stop and reschedule instead of pushing the last bay.
Send us the framing sequence
Share the structural drawings, the framing schedule and the owner's target dates. We will return a pour calendar, a list of hold points for the inspector and a price that shows formwork, placement and finishing as separate lines.
Common Questions
How long before the next floor can be formed on a new deck?
It depends on the engineer's strength requirement and on whether the deck is shoring-supported or reshored. We take cylinder breaks, compare them to the release criteria in the specification and tell the general contractor the earliest approved date. A cooler week can stretch the interval, which is why we put the dates on the calendar as targets rather than promises.
Can you pour a deck beside an operating airport apron or hospital?
Yes, with planning. The owner's representative usually controls truck routes, pour hours and noise or vibration limits, so we get those in writing early. We often shift pours to weekends or early mornings and keep the pump and truck staging off the active areas.
What drives the cost of an elevated slab the most?
Formwork and shoring, pump access, reinforcement density and the number of placements. A plain flat plate with room for the pump is far cheaper per square foot than a deck with deep beams on a crowded lot. Each of those items gets its own line in our proposal, which shows what a design change would save.
Do you handle post-tensioned decks?
We place and finish the concrete around post-tensioning and coordinate the specialty trade partner who installs and stresses the tendons. Stressing needs a minimum concrete strength, so the calendar has to include break results and a stressing window before forms can come down.
