Not every old building has to come down, and the first job of site prep on a redevelopment is to find out which ones do. Demolition and site preparation is the work of turning an occupied or abandoned property into a clean, buildable site: surveying what is there, disconnecting and capping utilities, abating hazardous materials, removing structures and pavements, sorting and recycling the debris, and grading the ground to a state that a new building can be designed around.
We handle the site side of that process, from the demolition of slabs, foundations and light structures to the removal of old pavement, tanks, fences, drives and buried obstructions. It is dirty work with a long list of ways to go wrong, and the right approach is methodical. We want to know what is under the ground before the machine does, who has to be notified before the first wall comes down, and where each material is going when it leaves. Redevelopment sites are often tight, occupied next door and full of surprises, and a plan that anticipates them is worth more than speed.
Survey, disconnect, abate, remove, grade
The sequence is firm. We begin with a site walk and the available drawings and records, then confirm hazardous materials surveys. Utilities are disconnected at the main, not at the building, and capped and documented. Asbestos, lead paint and other regulated materials are abated by licensed contractors before structural demolition starts, and we schedule around them.
Removal follows: structures are taken down with excavators and attachments, slabs and foundations are broken and removed, pavements are sawed and lifted, and buried items such as tanks, septic systems, wells and old pipe are located and handled. Concrete and masonry are crushed for reuse as base or fill where the specification allows, and metal is sorted for recycling. The cleared pad is then graded and compacted, with voids from foundations and tanks filled with engineered material, so that the ground is ready for a building pad or for the next phase of earthwork.
Rebuilds and conversions across the state
Large public projects show how redevelopment shapes the work. CBS Texas reported, with the page updated June 25, 2025, that the Kay Bailey Hutchison Convention Center rebuild in downtown Dallas is a $3.5 billion project, with most of the money going to rebuilding the facility, a model of 2.5 million square feet and completion scheduled for 2029. A rebuild of that kind generally starts with clearing the existing facility, and downtown demolition means dust control, noise limits, traffic management and careful sequencing next to occupied buildings.
Conversions are the other option. The Port of Galveston's April 20, 2025 press release describes the $156 million Cruise Terminal 16, which converts two existing cargo buildings into a 160,000-square-foot cruise terminal with a seven-story precast concrete garage providing more than 1,600 spaces, with the port's fourth cruise terminal scheduled to open in November 2025. That is selective demolition: interior removal, opening of walls and floors and preparation of the existing structure for new work, a skill set that overlaps ours. Owners deciding between a teardown and a conversion benefit from an early look at the structure and a price for each.
Hazards, notifications and permits
Demolition has its own regulatory path. An asbestos survey is generally required before demolition or renovation of a building, with notifications to the state and local authorities in advance. Cities require demolition permits, utility disconnect letters, and in some places a notice to neighbors and a rodent baiting or dust control plan. We confirm the requirements with the jurisdiction at the outset and make sure each is complete before the equipment arrives.
On the site, hazards include falling debris, unstable structures, silica dust, noise and heavy equipment. Water spray controls dust, exclusion zones keep people away from the work, and spotters watch the swing of the machine. Structures are taken down in a planned sequence, with an engineer's input on anything that is not a simple building. Concrete demolition and removal has its own procedures for slabs and elevated structures, and we apply them where the site calls for them.
What follows the demolition
Once the site is clear, the next steps are usually site clearing and grubbing of trees and vegetation, stripping and mass grading. A site with old foundations may need over-excavation to remove what is left of them, and one with old utilities needs utility relocation or abandonment in place with grout.
For commercial developers redeveloping an aging property, we can carry the whole sequence under one contract, which avoids gaps between demolition and earthwork where the schedule tends to slip. The same applies to healthcare and school campuses where a building is being replaced on an operating site.
Sequencing around neighbors and approvals
Approval times drive the schedule more than the equipment does. Demolition permits, asbestos notifications and utility disconnects take days or weeks, and a project that starts them late loses time. We submit permits as soon as the owner approves the scope, and we plan the abatement and the demolition as a continuous operation to avoid standby.
Occupied neighbors affect hours and methods. A site next to a hospital, a school or a residential block may require work during limited hours, extra dust control and vibration monitoring. We plan the work to meet those limits, and we communicate with neighbors in advance so that the noise and the trucks do not come as a surprise.
What makes a demolition estimate move
Hazardous materials are the largest unknown, followed by the extent of foundations and buried items. A building with asbestos in the floor tile and the roofing costs more than one without, and a site with abandoned tanks and a septic field costs more than a clean lot. Recycling value can offset some costs, particularly for concrete and metal, but disposal fees for mixed debris and regulated waste can overwhelm it.
We bid demolition with clear unit prices for the items that are uncertain, such as additional slab, buried concrete and unsuitable soil. That way the owner is paying for what is found, and not for a contractor's worst-case guess.
Tell us what is standing on the site
Tell us what is standing on the site, and what you plan to build. We will walk the property, review the records and price the removal, recycling and grading as one scope.
We flag the unknowns early so they do not turn into delays.
Common Questions
Do I need an asbestos survey before demolition?
In most cases, yes. An asbestos survey is generally required before demolition or renovation of commercial buildings, and the results determine whether abatement is needed first. The owner or a consultant orders the survey, and we coordinate the schedule.
What happens to the debris?
We sort it on site or at a recycler. Concrete and masonry can be crushed and reused as base, metal is recycled, and the remaining waste goes to a permitted landfill. We keep tickets so the owner can verify what was moved.
Can you demolish next to an occupied building?
Yes, with planning. We use controlled methods, vibration monitoring and dust control, and we agree on hours and procedures with the neighbor. Some structures call for hand demolition or sawing instead of heavy machines.
How do you handle old foundations and buried utilities?
We locate them with records and probing, then remove or abandon them according to the plans. Voids are filled with compacted material, and utilities are capped at the main with documentation.
How long does a demolition project take?
It depends on the structure and the approvals. Permits and abatement often take longer than the demolition itself. We give a schedule that includes those steps so the owner knows when the site will be ready.
