Level of Development (LOD) is defined by BIMForum and describes the completeness of information contained in a BIM model element at a specific project phase. LOD 100 is concept-level massing. LOD 200 is approximate size and location. LOD 300 is construction document level — specific size, shape, location, quantity, and orientation sufficient for coordination and permit. LOD 400 is fabrication level. LOD 500 is as-built. For most commercial and residential construction in South Florida, LOD 300 is the minimum required for permit coordination and clash detection. Federal and DOD projects typically require LOD 350 or 400 for systems in congested areas. BAM defines the LOD for each discipline and each project phase in the BIM Execution Plan drafted at project intake, so both the owner and design team have a documented expectation for every model element.

A clash is a physical conflict between two model elements — for example, a mechanical duct routed through a structural beam, or a sprinkler line intersecting a concrete shear wall. When clashes are detected in the model, the resolution cost is design time: a coordination meeting, a revised drawing, a repositioned element. When clashes are discovered in the field after the concrete is poured or the steel is erected, the resolution cost is demolition, rework, and schedule delay. Industry benchmarks consistently show field clash resolution costs 3 to 5 times the pre-construction equivalent. On a project with 200 resolved pre-construction clashes, the cost differential between field resolution and model resolution can exceed the entire BIM coordination fee. BAM performs clash detection in Navisworks before permit submission, with a target of zero hard clashes at construction start for all coordinated elements.

The U.S. General Services Administration has required BIM on all new federal building projects since 2007. The Department of Defense Unified Facilities Guide Specifications include BIM requirements for facilities over 10,000 SF. The Army Corps of Engineers has required BIM deliverables conforming to the National BIM Standard-US on applicable projects since 2012. The specific LOD, software format, and deliverable schedule are defined in the project's BIM Execution Plan, which BAM prepares at project intake for federal and DOD work. BAM holds documented DOD performance history from the U.S. Army Reserve armory renovation in Arcadia, Florida. The CPARS record from that project documents federal-grade QC and documentation standards. Federal procurement offices reviewing BAM's qualification package receive both BIM capability documentation and the CPARS record as part of the technical submission.

The as-built BIM model delivered at closeout reflects the project as actually constructed, incorporating all RFI responses, change order modifications, and field deviations from the permitted drawings. BAM delivers the as-built model in native Revit format and as an IFC export for software-neutral access. The model includes all element properties, material specifications, and manufacturer data for installed systems and equipment — the minimum required for building lifecycle management and facility maintenance planning. For HOA boards and condo associations, the as-built model becomes the building's structural and systems record, available for future renovation planning, reserve study cost validation, and insurance claim documentation. For federal facilities, the as-built BIM model is submitted to the GSA or Army Corps project record in accordance with the contract's BIM Execution Plan deliverable schedule.
