Project Overview

A multidisciplinary engineering consultancy in Atlanta engaged our team to develop fully coordinated Structural and Architectural BIM models for a 20,800 sq. ft. two-story institutional facility. Updated models were never made available by the broader design team, creating a critical coordination gap at the Construction Documents stage.

We deployed a dedicated BIM team, including an Architect, a Structural Engineer, and a Project Manager. Working from the available IFC model and issued construction drawings, the team independently developed all discipline models. Construction-ready content was delivered alongside high-quality Lumion renderings.

Client Challenges

Pain Points of the Client

Updated Models Not Delivered

The design team did not provide updated Architectural, Structural, or MEPF models at the CD stage, leaving the client without a coordinated model set.

Incomplete Architectural Revisions

The architectural model had limited revisions and did not reflect the latest construction drawings, making it unreliable for coordination or documentation.

No Structural or MEPF Starting Point

Structural and MEPF models were not shared by the design team, leaving no baseline for building, coordinating, or validating engineering systems.

Coordination Gaps Across Disciplines

Interdisciplinary coordination stalled without updated models across all three disciplines, hindering discrepancy identification and resolution.

Risk of Downstream Documentation Errors

Proceeding with outdated or incomplete models risked propagating errors into construction documentation, permit packages, and contractor-facing deliverables.

Internal Capacity Constraints

The client's team could not rebuild and coordinate three discipline models while handling ongoing engineering and client responsibilities.

Our Approach

How We Solved It

Independent Model Development

Architectural and Structural models were developed from the ground up using the available IFC model, construction drawings, and applicable standards.

Architectural Model Refinement

The available model was reviewed against revised PDFs. Missing walls, outdated elements, and furniture mismatches were corrected floor by floor.

Structural System Modeled from Scratch

The complete structural model was developed independently, covering framing, beams, columns, connections, and wall footings, with attention to complex junction conditions.

Structured Coordination List

A comprehensive coordination list was prepared at project outset, documenting all issues, responsible disciplines, and required actions for a traceable process.

Proactive Clarification Requests

Formal clarification requests were raised and documented for ambiguous items before modeling decisions were finalized and validated

Day-Wise Work Planning with QC

Coordination items were distributed across a structured daily work plan, with dedicated QC hours allocated before each submission for accuracy

Execution Strategy

End-to-End Project Delivery Through a Phase-Controlled Approach

The project was delivered across sequential stages, with each phase reviewed and confirmed before the team advanced. This phase-gated approach ensured that model content, coordination items, and client approvals were progressively locked in, reducing rework and maintaining forward momentum.
