BIM Structural Coordination in Florida

The conflicts that coordination is designed to catch are specific and predictable. A structural beam at the elevation the engineer specified occupies the same space as the HVAC ductwork the mechanical engineer routed through the same bay. A column lands in a location the architect's reflected ceiling plan didn't account for. A concrete shear wall runs through a space the MEP engineer planned to use for a major equipment chase. A floor penetration for plumbing runs through a post-tensioned slab zone where cutting is not permitted.

Every one of these conflicts has a resolution - but the cost and disruption of that resolution depends entirely on when it is found. Found during BIM coordination before documents are issued: a design revision, a model update, a revised sheet. Found in the field during construction: a contractor RFI, an engineer response, a change order, a schedule impact, and in some cases, remediation of work that was already built.

BIM structural coordination moves the discovery of those conflicts from the job site to the design phase. That is what it is for. Everything else - the visual quality of the model, the sophistication of the software, the resolution of the elements - serves that purpose.

Structural-architectural coordination

We receive the architect's Revit model and coordinate the structural model against it - aligning column grids with the architectural layout, resolving structural member locations against ceiling heights and floor elevations, and identifying structural elements that conflict with architectural program. Coordination happens during design development, when the cost of a design adjustment is a model revision rather than a change order.

Structural-MEP coordination and clash detection

Structural-MEP coordination is where the most consequential field conflicts originate, and where BIM coordination delivers the clearest value. We run clash detection between the structural model and the mechanical, electrical, and plumbing models - identifying hard clashes (physical overlaps), soft clashes (clearance violations), and workflow conflicts - and work with the MEP engineer to resolve them before documents are issued. Beam penetrations for MEP routing, sleeve locations in concrete members, and equipment clearance conflicts are resolved in the model, not in the field.

Coordinated structural drawings from the model

Structural plans, elevations, sections, and details are produced directly from the Revit model - ensuring that what is drawn reflects what is modeled, and that coordination changes are reflected consistently across the full set of documents. Sheet-by-sheet manual updates that don't propagate through the full drawing set are eliminated when drawings are model-derived.

Federated model participation

On projects where the full project team is working in a federated BIM environment - using Autodesk Construction Cloud, BIM 360, or a project-specific common data environment - we participate in the federated model workflow: sharing the structural model in the project environment, participating in coordination meetings, tracking and resolving clash issues through the project's BIM execution plan, and delivering model updates on the project's coordination schedule.

Construction-phase model support

When conditions change during construction - field-verified dimensions that differ from design drawings, design modifications that result from contractor RFIs, added scope - we update the structural model to reflect the change and issue coordinated revised documents. The structural model remains current through construction, rather than diverging from actual conditions as changes accumulate.

Duran's dedicated BIM Director changes that relationship. The BIM Director is involved in structural projects from the start - not as the person who drafts the engineer's sketches, but as the person who ensures the structural model is built to coordinate from the beginning: at the right level of development, in the right shared coordinate system, with the structural geometry developed in three dimensions rather than as a projection of 2D thinking into a 3D environment.

The practical result is a structural model that is genuinely useful for coordination - not a Revit file that looks like the drawings but doesn't carry the geometric accuracy needed to detect real conflicts. Architects and MEP engineers who have coordinated with Duran's structural models on previous projects come back to Duran in part because the model they receive is worth coordinating against.

General contractors managing the pre-construction coordination process. GCs who require a coordinated BIM model as a condition of construction document acceptance need a structural engineer who participates in the coordination process - not one who delivers a Revit file and considers BIM complete. We participate in GC-led coordination meetings, respond to clash reports, and update the structural model as coordination progresses.

Developers and owners who have absorbed change order costs from coordination failures. The case for BIM structural coordination is most clearly made to owners who have been through a project where coordination failures generated significant change order costs. The incremental cost of coordination - done correctly, during design - is reliably less than the change order cost of finding the same conflicts during construction.

Healthcare, commercial, and institutional projects where MEP complexity is highest. The structural-MEP coordination value is greatest on projects with dense, complex MEP systems - hospitals, medical office buildings, laboratory facilities, data centers, and similar occupancies where mechanical and electrical systems compete for structural interstitial space across the full building. These are the project types where coordination failures are most expensive and most disruptive.

• Beam-to-duct conflicts in mechanical plenum space. The single most common structural-MEP conflict. Structural beams at the elevation required by the structural design intersect with primary HVAC ductwork at the elevation the mechanical engineer routed it. Neither engineer saw the other's drawings in three dimensions before issuing. The conflict surfaces when the framing is in place and the mechanical contractor attempts to install ductwork. Resolution: field modification of the structural beam (typically a web penetration or a beam relocation), a change order, and a schedule delay. Prevention: structural-MEP clash detection during design.
• Column locations that conflict with architectural program. A structural column lands in the middle of a corridor, inside a plumbing fixture, or at a location the architecture assumes is open. In a 2D design process, column locations shown on the structural plan are often not cross-referenced against the architectural reflected ceiling plan, equipment layouts, or interior elevations until the drawings are assembled for permit. In a BIM coordination process, the structural and architectural models are overlaid and the conflict is visible in three dimensions during design development.
• Slab penetrations in post-tensioned zones. Post-tensioned concrete slabs are common in Florida's commercial and multifamily construction. MEP penetrations through post-tensioned slabs require careful positioning to avoid cutting tendons - a structural failure mode with serious consequences and significant repair cost. Structural BIM coordination identifies MEP penetration locations that conflict with post-tensioning layouts before slabs are cast, allowing penetrations to be repositioned during design rather than cored through a cast slab with active tendons.
• Structural-architectural elevation mismatches. Structural slab elevations, beam bottom elevations, and floor-to-floor heights as modeled by the structural engineer sometimes differ from the architectural drawings by amounts that don't show up in 2D coordination but become apparent in 3D. Ceiling heights that the architect assumes are achievable are in fact not - the structural depth plus MEP below the structure leaves insufficient space for the finished ceiling. BIM coordination makes this visible during design, when the architectural program can be adjusted rather than after the structure is framed.
