Baltimore Sun Building Demolition
Baltimore, Maryland
ISI Demolition performed the full building raze of the former Baltimore Sun printing plant and offices at Baltimore Peninsula, a roughly 450,000-square-foot structure with some of the largest steel columns our crews had ever encountered. Working tight against an active sidewalk, a hotel, nearby offices, and an adjacent parking garage under construction, our team managed working-hour restrictions, dust suppression, and material segregation to keep the site organized and the surrounding community undisturbed, while also donating and repurposing 80% of the building’s leftover furniture, fixtures, and equipment.

Full Building Takedowns, On Schedule
Since 1990, ISI Demolition has had the team, process, and equipment to get a job done on time and on budget. We know how our work affects everything that follows: any delay on our end stalls the rest of the construction schedule behind us.
- We’ve invested in our fleet of heavy equipment, so there’s no waiting on a rental machine tied up on someone else’s job.
- We run daily and weekly quality control meetings on every project, so nothing about the plan or the site conditions gets discovered halfway through.
- Our staff handles daily demolition work, giving us full control of the schedule.
- We get involved with general contractors and developers as early as possible, handling pre-demolition surveys and permitting support before equipment ever moves.
Since expanding to Florida in 2014, that same standard applies in the Southeast. Whether the project is in Maryland or Florida, the same supervision, processes, and equipment standards hold.

Everybody assumes demolition means take it all down as fast as possible. Part of the job is having the right team, owning the equipment, and knowing how to mobilize operations so the schedule holds.
Every Plan Backed by In-House Structural Engineering
Every building razing project is reviewed by ISI Demolition’s in-house structural engineers before work begins. Sequencing, shoring needs, and site-specific risks get planned for upfront so that demolition moves smoothly once we start.
“ISI differentiates itself from competitors with the ability to thoroughly plan the work, engineer challenging solutions, and execute the plan.” Brian Hetherington, Construction Executive, Clark Construction
When buildings are unpredictable, having this skillset on our team means load paths get confirmed and plans get adjusted before they become a problem in the field, not after.
From Standing Structure to Clean Site
On a recent college dorm raze in South Florida, ISI Demolition took a seven-story building down to a cleared site in eight weeks. Here’s how the work came together:
Preconstruction Planning
Before the high-reach arrived, our team mapped the full sequence: what comes down first, where equipment stages, how material moves off site, and what needs protecting along the way. Our in-house structural engineers reviewed the plan, and estimating, safety, and field leadership aligned on it before mobilization.
Phased Demolition
With access open, a high-reach excavator took the building down from the top, floor by floor, controlling where material fell. Crews sorted concrete, steel, and debris as it came down, so processing kept pace with the takedown instead of piling up behind it.
Full Site Clearing
Once the structure was down, crews processed and hauled the remaining material and removed foundations and slab, leaving a cleared site ready for the next phase. For the GC, that’s the handoff that matters: a clean site on the date we committed to.

Our Team Can Handle Any Conditions
Every site comes with its own problems to solve, and you need to know they’ll get solved without you finding out the hard way. That starts with the team. ISI Demolition’s crews have seen enough conditions to know what to expect, backed by the fleet to handle what they find. Here’s how that plays out on the ground.
When the site sits close to active neighbors
For buildings in dense, urban, or occupied areas, we plan sequencing and containment carefully to keep the surrounding environment safe and operational, minimizing disruption to neighboring properties and pedestrians.
When utilities and permitting stand in the way
Before a single wall comes down, our team coordinates utility disconnection with providers and supports permitting and environmental compliance, so nothing unexpected halts progress mid-project.
When precision matters as much as power
Our fleet of remote-controlled demolition robots delivers the force of much larger machines in spaces where precision and control are critical, along with high-reach excavators for multi-story takedowns.
When the site needs to be truly clean
Debris is sorted on site and processed for recycling, with a minimum 75% diversion rate on our standard process and most projects running well above that. Concrete is crushed in-house and reused, which cuts hauling and controls costs.
Featured Project:
Bernie McCabe Courthouse Demolition
St. Petersburg, Florida
ISI Demolition was hired for a full range of demolition services on the 80,625 square foot Sebring Building. Work included bringing down a five-story building and a one-story building to make way for the Bernie McCabe Courthouse project in St. Petersburg, Florida. In just one month, ISI Demolition brought down both buildings and removed all pile caps, piles, spread footings, and grade beams without incident.
With both structures and every foundation element out in a single month, the courthouse team started on a clean site with no below-grade obstructions left to work around.

The Most Common Questions GCs Have About Building Razing
How does building razing affect my project schedule?
Razing typically runs from a few days for a single small structure to several weeks for large or multi-building sites. Because we own our equipment and run our own crews, we control that timeline instead of waiting on rentals or subs, so it’s easier to hold to the schedule you’ve already committed to your client.
Who handles permitting and utility disconnection, us or you?
We coordinate demolition permitting and utility disconnects with providers, and coordinate abatement with licensed partners, so it’s off your plate.
What if the structure has unexpected conditions once we’re into it?
Every project is reviewed by our in-house structural engineers before work begins, so load paths, shoring needs, and site-specific risks are planned for upfront. If something changes once we’re in it, we have the in-house team to adjust without waiting on a third party.
Can ISI Demolition work around an active site or tight urban footprint?
Yes. We regularly work tight against occupied buildings, active sidewalks, and adjacent construction, planning sequencing and containment to keep neighbors and other trades operating safely.
What’s left on-site when demolition is finished?
Debris is sorted and managed for recycling and disposal, with a focus on material recovery and hauling efficiency, so you’re handed a clean site ready for the next phase. Our standard process diverts at least 75% of material from landfill.
Where does ISI Demolition work?
ISI Demolition is headquartered in Maryland with a regional office in Florida, and works throughout the Eastern U.S., including Pennsylvania, Delaware, Virginia, Washington, DC, and Tennessee. Every project runs with the same supervision, processes, and equipment standards.
