A retail-to-medical-office conversion may require more than removing partitions and finishes. New exam rooms, treatment spaces, staff areas, and equipment can call for plumbing, electrical, and other utility routes that the original retail layout did not need. If those routes pass through a concrete floor or wall, the openings should be planned with the design team and installing trades before selective demolition or concrete cutting begins.
The practical sequence is to confirm the intended layout and utility routes, identify what is in or below the areas to be cut, define the demolition limits, coordinate permits and site requirements, and schedule openings around the work of other trades. That planning helps the owner and general contractor reduce avoidable conflicts, rework, and disruption to retained areas.
Start with the medical-office layout and utility plan
Retail space is often open and flexible, but a medical-office plan can introduce more rooms, fixtures, equipment, and service points. Before demolition is priced or scheduled, the project team should establish where the new spaces go and what each space needs.
The owner or design team should coordinate the room layout with the appropriate licensed design professionals and installing trades. Confirm the planned locations and requirements for items such as sinks, toilets, floor drains, electrical service, data, and any specialized equipment. The exact requirements depend on the intended use and project design; this article is general planning information, not a substitute for design or code review.
A marked-up plan can help the demolition contractor understand what must be removed, what remains, and where openings may be needed. It should distinguish confirmed routes from assumptions that still need field verification.
Identify what is in and below the slab
A proposed opening on a drawing does not establish that the slab is clear to cut. Before work, the project team should determine what information is available about the floor assembly and existing services, and arrange suitable scanning or other investigation where needed. Existing drawings may be incomplete or differ from field conditions.
The responsible design and construction professionals should resolve questions about structural elements, embedded systems, and the effect of openings on the building. A concrete-cutting contractor can use the approved location and scope to plan the cutting method, access, water or dust controls, and material handling. Do not ask a demolition crew to decide whether a structural element can be cut or moved.
If hazardous materials may be disturbed, arrange the required assessment and work sequencing before demolition. Atlas coordinates asbestos testing through an independent third-party inspector and accredited laboratories; Atlas does not perform in-house testing or lab analysis. Abatement and clearance responsibilities should be set for the specific project before affected materials are disturbed.
Define selective demolition limits
A clear scope identifies the partitions, floor finishes, fixtures, and other components to remove, as well as the areas and building elements to protect. For an occupied center or a building with adjacent tenants, the general contractor should also define access, work hours, temporary separations, debris routes, and how the work area will be maintained.
Photographs and marked-up plans can make boundaries easier to communicate. Identify who can authorize field changes, particularly when concealed conditions or additional removal are discovered. If the layout changes after openings are cut, new locations or dimensions may affect other trades and require revised approvals.
Coordinate new utility openings with the installing trades
Before cutting, confirm each opening’s approved location, dimensions, quantity, and purpose with the relevant project team. The plumbing, electrical, mechanical, and other trades should confirm their routing and installation needs. The general contractor should coordinate the sequence so the concrete work does not conflict with other site activities or block access needed by crews.
The scope should address practical details such as:
- Who provides final opening locations and confirms dimensions.
- Whether the work involves core drilling, wall sawing, floor sawing, or another approved approach.
- How the work area will be accessed and isolated from surrounding operations.
- How water, dust, slurry, cut material, and debris will be managed for the specific site.
- Who receives and protects the opening after cutting, and who completes subsequent installation and restoration.
Responsibilities vary by contract. Confirm them in writing rather than assuming that the concrete-cutting scope includes utility installation, structural design, patching, or finish work.
Sequence the work around other contractors
Medical-office conversions commonly involve multiple trades working from a changing design and construction schedule. A sequencing conversation before mobilization should cover prerequisites, access, work-area handoffs, and how schedule changes or added work will be approved.
A useful project sequence is:
- Confirm the intended room layout and utility needs with the project design team and trades.
- Review available existing-condition information and investigate proposed opening locations as needed.
- Set demolition boundaries, protection measures, access, and debris handling.
- Complete applicable reviews, permits, and hazardous-material coordination before affected work starts.
- Perform selective removal and approved concrete cutting in the agreed sequence.
- Turn over openings and work areas to the responsible installing trades, then document changes and remaining scope.
This is a planning framework, not a fixed schedule. Permit needs, building conditions, tenant operations, hazardous materials, and trade availability vary by project and jurisdiction.
Plan for changes and concealed conditions
A retail floor can conceal conditions that are not shown on old drawings. The project team should agree in advance how work pauses, who evaluates an unexpected condition, and how changes to location, method, schedule, or cost are authorized. This keeps field decisions with the people responsible for design, safety, and project approvals.
When comparing bids, look for a defined quantity and location of openings, stated assumptions, access and protection requirements, debris handling, and clear exclusions. A site visit and coordinated drawings provide a better basis for pricing than a general request to “cut for utilities.”
Frequently asked questions
Should concrete openings be planned before demolition starts?
The project team should identify likely utility routes and opening locations early, then confirm them with the responsible design professionals and installing trades before cutting. Some finish removal may be needed to verify field conditions, but cutting based only on an unconfirmed concept can create avoidable conflicts.
Who decides whether a slab can be cut?
The appropriate design professional and project team should determine whether a proposed opening is acceptable for the building and its intended use. The concrete-cutting contractor performs work to the approved scope; cutting work is not a substitute for structural review.
Does concrete cutting include installing the utilities?
Not by default. Concrete cutting or coring creates an opening within the agreed scope. Utility installation, structural design, patching, waterproofing, and finish restoration may belong to other trades or separate scopes. Confirm the handoff in the contract documents.
What affects the cost of new utility openings?
Cost can depend on the number, size, thickness, and location of openings; the cutting method; access; protection and containment needs; material handling; site operating conditions; and coordination or investigation required before cutting. A contractor needs project details and site conditions to prepare a meaningful scope and price.
