Before a new building can rise on an old site, something has to come down. Demolition and site prep removes existing structures, slabs, pavements, foundations, tanks and utilities, then clears and grades the ground so the next phase starts on a clean lot. It sounds like the easy part of a project, and it is often where the biggest schedule surprises hide: a buried foundation nobody drew, an abandoned line that still holds product, a slab thicker than the plan said.
We run demolition and site prep as a planned sequence, not a sweep. Surveys, hazardous material checks, utility disconnects, permits and neighbor notices come first. Then the structure comes down in an order the engineer and the demolition partner agree on, debris is sorted for recycling or disposal, and the site is cleared and graded to a surface the next trade can use. We coordinate the trade partners involved and keep the owner's rep informed, so the lot is ready by the date the new pour calendar assumes.
What lies on and under an existing site
Every older site carries history. Foundations extend beyond the building line, old utilities run under slabs, and past uses leave tanks, sumps and contaminated soil. Our first task is to gather every record available, including old drawings, owner knowledge and utility maps, and then verify them in the field with potholing and scanning where needed.
Hazardous materials are the other major variable. Asbestos, lead paint and fuel residues require surveys and licensed abatement before demolition begins. The results shape the schedule and cost, and we ask for them before committing to a date. If an unexpected condition appears mid-job, we stop, document it and bring in the right specialist.
Neighbors and the public are part of the project conditions. A demolition on a busy street raises dust, noise and truck traffic, and we plan watering, working hours and street protection before the first machine arrives. Adjacent owners receive notice, and any shared walls, easements or utilities are identified so that nothing is damaged by accident.
Fitting teardown ahead of the new work
Demolition leads directly into earthwork, utilities and foundations, so its schedule drives the rest. Permits, utility disconnects and abatement take time, and they should start well before the demolition itself. We assemble a checklist of these items with dates and owners.
Once the structure is down, debris removal and clearing follow in quick succession so the lot does not sit cluttered. Slabs and foundations are removed or crushed as the plan requires, voids are backfilled and compacted, and the site is graded. Crushing concrete on site, when permitted, reduces trucking and produces material the new project can reuse as base, though the engineer must approve the gradation first. The new pad can then be prepared under building pad preparation, with minimal downtime between phases.
Structures that come down
Old office buildings and retail strips are the most common demolition projects in a mature city. They are usually steel or masonry with concrete slabs, and the work is a matter of careful sequence and debris handling. The site of an office building may also hold parking, utilities and landscape that must be cleared.
Aviation sites carry their own history. Midland Army Air Field operated from 1942 to 1946 as a bombardier training school, and its facilities became the basis of the city's airport. Hangars and support buildings from earlier eras may need demolition before modern aircraft hangars can be built, and the old aprons below may hold surprises in thickness and reinforcement.
Owners who clear sites
Industrial and manufacturing owners regularly replace obsolete buildings, process areas and storage yards. Their sites often hold equipment foundations, pits and tanks, and demolition has to proceed in a way that protects adjacent operations. We plan around active plant schedules, restricted access and permit-to-work systems.
Commercial developers buy older properties for redevelopment and want a clean lot on a firm date, usually because a tenant or a lender is waiting on it. They value an upfront estimate of demolition quantities and an inspection record that satisfies lenders and the city.
What drives the cost
Building size and type, foundation depth, abatement, disposal fees and haul distance are the main drivers. Recycling concrete and steel can offset some costs, and we credit what is recovered. Unknowns, such as buried tanks or contaminated soil, are carried as allowances so the owner sees where risk lies. We also separate the price of demolition from the price of restoring the ground, because owners sometimes buy only the first and assume the second is included. Backfilling basements, tanks and utility trenches to engineered standards is a distinct task with its own testing.
Access and neighbors matter too. A tight downtown lot needs smaller equipment, protected sidewalks and controlled dust, while a yard on the edge of town can take larger machines. Disposal routes affect price and schedule, and our page on import, export and haul-off covers the logistics.
Coordinating demolition partners
We coordinate trade partners for demolition, utilities and earthwork. Each partner holds the licenses and equipment for its piece, and we hold the sequence. The utility partner disconnects lines, the abatement contractor clears hazardous materials, the demolition partner takes down the structure and the earthwork partner clears and grades.
Concrete trade partners place and finish concrete, and when the project calls for removing concrete, our understanding of reinforcement and thickness helps. For slab removal and cutting, see concrete demolition and removal, and for clearing vegetation and stumps, site clearing and grubbing.
Where the old meets the new
In Midland, redevelopment spreads from downtown and along the loop. Loop 250 is a 12.245 mile bypass along the west, north and east edges of the city, running from I-20, SH 158 and SH 349 in southwest Midland to I-20 east of the city. TxDOT is planning to reconstruct and widen I-20 in Midland County from east of FM 1208 to east of SH 349, about 12.8 miles, with 26.3 acres of added right-of-way, and parcels near the corridor may change hands and be redeveloped.
We mobilize trade partners to Midland and nearby communities. Dense areas such as downtown Midland require careful planning for noise, dust and street closures.
Send the existing site survey and the new plans
Share the existing conditions survey, any asbestos or environmental reports and the plans for the new building. We will return a demolition and clearing sequence with permits, disposal routes and the date the site is ready for new work.
Common Questions
What permits are needed for demolition?
A demolition permit from the local permit office is standard, along with notices for asbestos where applicable and utility disconnect confirmations. We gather the list during planning and submit early.
How do you handle asbestos or lead?
A survey identifies them, and licensed abatement contractors remove them before demolition. We do not start structural demolition until abatement is cleared.
Can concrete from demolition be reused?
Often yes, after crushing, as base or fill if it meets the specification and the engineer approves. Reinforcing steel is separated and recycled.
What happens to old foundations and slabs?
Whether they stay or go depends on the new design. Where the new building will sit on the same ground, old footings and slabs are usually removed and the voids are backfilled in tested lifts. Where they fall outside the new footprint, the engineer may allow them to be broken up and left in place.
How long does demolition take?
It depends on size, type and abatement. Permits and disconnects usually take longer than the teardown. We give a duration once we have the survey and hazardous material results.
