Commercial BIM Services: MEPF Coordination and 5D Quantity Takeoffs for U.S. Commercial Construction

Clash resolution at Design Development, clean construction documents, quantity takeoffs fast enough to support a competitive bid.

Commercial construction runs on speed and margin. A coordination process that's accurate but slow costs the bid before it costs the schedule. Excelize builds commercial BIM delivery around that constraint, coordinated fast enough to matter at Bidding, not just accurate enough to matter at Construction Administration.

Fast enough for the bid, not just the build What we deliver

Why bidding off unlinked drawings costs the job

Manual measurement error, straight into the number

Commercial GMPs are won and lost on the accuracy and speed of the estimate. A takeoff built from unlinked 2D drawings inherits every manual measurement error straight into the number, and on a competitive bid, that error either prices the job too high to win or too low to protect margin once construction starts. Neither outcome is visible until it's too late to fix.

Caught early it’s a design change, caught late it’s the schedule

The same timing problem shows up in coordination, not just estimating: catch an issue early, and it's a design adjustment; catch it late and it becomes a schedule problem the margin has to absorb.

Accurate and fast, not one or the other

Excelize scopes commercial engagements around both constraints at once: coordination has to be accurate, and it has to move at the pace a commercial bidding and construction schedule actually requires.

A clash resolved in the federated model at Design Development costs a modeling adjustment. The same clash found on site costs three things at once: an RFI to document it, a change order to resolve it, and a slipped trade sequence while the fix gets made, on a project type where the schedule is usually already tight and the margin usually already thin.

What We Deliver

What gets coordinated in a commercial BIM model

Hard Clash Resolution

Physical intersections between MEPF, structure, and architectural elements, resolved at LOD 300 across the federated model.

Soft Clash Resolution

Clearance and access violations that don’t show up as a physical intersection but block maintenance access or code-required clearances.

LOD 350 Construction Document Extraction

Clean enough to move directly into permitting without a second round of drawing cleanup.

Model-Linked 5D Quantity Takeoffs

Tied to the coordinated model rather than manual measurement, supporting a GMP submission inside a typical three- to six-week bidding window.

How we keep commercial coordination on schedule

Federated coordination review

Runs once per project phase, tied to the BIM Execution Plan agreed at kickoff, so clash resolution happens on a predictable cadence rather than as an open-ended process.

Discipline-lead sign-off

Happens at each checkpoint, not just the modeler who built the geometry, so a clash resolution isn't considered final until someone with authority over that discipline has confirmed it.

QTO extraction off the coordinated model

Runs directly off the coordinated model, not a separate manual takeoff, so the estimate reflects what's actually been resolved, not what the drawings assumed before coordination.

A commercial project's coordination review can't slow down the bid or construction schedule to be thorough, so the review structure is built for both speed and completeness at the same time.

What a late-caught commercial clash actually costs

A clash resolved in the federated model at Design Development costs a modeling adjustment. The same clash found on site costs three things at once: an RFI to document it, a change order to resolve it, and a slipped trade sequence while the fix gets made, on a project type where the schedule is usually already tight and the margin usually already thin.

What GCs and estimating teams check before shortlisting Excelize

Methodology

BIM and coordination workflows aligned with ISO 19650 information management principles, a working methodology, not a certification.

FAQs

Commercial BIM: frequently asked questions

Yes. Model-linked QTOs are scoped to fit a typical three- to six-week bidding window, so estimating teams get numbers tied to the coordinated model rather than a separate manual takeoff.

Hard clashes are physical intersections between systems. Soft clashes are clearance or access violations, maintenance access, code-required clearances, that don’t physically overlap but still block the space from working as designed. Excelize resolves both at LOD 300.

LOD 350 documents are extracted directly from the coordinated federated model, which is what keeps them clean enough to move into permitting without a second cleanup pass.

Both. Engagements range from single-building tenant fit-outs to multi-phase, multi-building commercial programs.

Get BIM coordination built for commercial speed and margin

A clash found on site doesn't just cost a change order. It costs the schedule buffer a commercial project doesn't have. Protect the margin before the bid closes.
