Introduction

BIM models that clear coordination review before they clear the ground floor

Chicago gave the world the steel-frame skyscraper, and Illinois construction still moves at that scale - dense high-rise cores in the Loop, sprawling single-story data center shells in Grayslake, and everything in between. A BIM model built for a 40-story tower has to coordinate differently than one built for a distribution center, and a model that isn't checked against the right code cycle for its jurisdiction creates rework long before steel goes up.

Drafting Buddies has produced BIM models and coordinated federated model sets for architects, structural and MEP engineers, general contractors and fabricators across all 50 states for over a decade, with Illinois as one of our busiest markets - driven by the Chicagoland data center corridor, Stellantis' reopening of its Belvidere manufacturing plant, and a steady pipeline of commercial, healthcare and institutional construction statewide. Every Illinois BIM engagement starts with confirming which code edition and local amendments apply to the project's jurisdiction, whether that's the home-rule Chicago Building Code or the statewide baseline now in effect under Public Act 103-0510.

Whether you need an architectural Revit model for a Naperville mixed-use development, a structural steel model coordinated with a fabricator's Tekla workflow, or a fully federated architectural-structural-MEP model with clash detection for a Joliet warehouse expansion, our team works at the LOD your project phase actually requires - not an inflated model that costs more to produce and takes longer to review than the project needs.

Illinois Building Code Landscape

Built Around the Code Cycle Your Jurisdiction Actually Enforces

Illinois shifted from a state with no unified building code to a statewide baseline under Public Act 103-0510, requiring every municipality and county to enforce a code drawn from the 2018, 2021 or 2024 ICC family, with rolling compliance deadlines through 2025–2026. Home-rule cities keep their own amended codes layered on top of that floor.

  • Chicago Building Code

    Locally amended, enforced independently of the statewide baseline inside city limits.

  • Statewide baseline (PA 103-0510)

    2018 / 2021 / 2024 IBC, IRC & IEBC family, mandatory where no local code exists.

  • Illinois Accessibility Code (2018)

    Governs accessibility statewide, including on public-agency BIM projects modeled to 2024 IBC.

  • Illinois Energy Conservation & Plumbing Codes

    Mandatory statewide regardless of local building code adoption.

The Model, Floor by Floor

Level of Development, mapped like a building section

Every Illinois BIM engagement is scoped to a defined LOD before modeling starts, so your team knows exactly what geometry and data to expect at each stage - from early massing through as-built handover.

We scope LOD per discipline and phase rather than defaulting every element to LOD 500, keeping model file sizes manageable and review cycles fast for GCs and design teams working on tight Illinois schedules.

    LOD 100

    Conceptual Massing

    Generalized geometry for early design and feasibility studies

Sub-Services

Illinois BIM sub-services

Twelve discipline-specific BIM modeling and coordination services, each scoped to Illinois project delivery and code-review requirements.

SVC 01

Architectural BIM Modeling Illinois

Full architectural Revit models covering floor plans, elevations, sections, wall assemblies and finish schedules, built to the LOD your design phase requires. Models are coordinated against the architect of record's design intent and checked against the Illinois Accessibility Code and any local amendments governing your project's jurisdiction, giving your team a model that supports design development, permitting and construction documentation without conflicting geometry between phases.

SVC 02

Structural BIM Modeling Illinois

Structural steel, concrete and precast BIM models built in Revit Structure or Tekla, including framing, connections, foundations and reinforcement, coordinated with the structural engineer of record's design and the governing wind and seismic provisions for your Illinois jurisdiction. Models are built at fabrication-ready LOD when required, so structural steel and precast fabricators can move from coordinated model directly into shop drawing production.

SVC 03

MEP BIM Modeling & Coordination Illinois

Mechanical, electrical and plumbing BIM models covering ductwork, piping, conduit routing and equipment placement, coordinated against architectural and structural models to flag ceiling-space and shaft conflicts early. Models are checked against the National Electrical Code and Illinois Plumbing Code, giving mechanical, electrical and plumbing subcontractors a coordinated model rather than three separately modeled trades that clash once construction starts.

SVC 04

BIM Clash Detection & Coordination Illinois

Federated architectural, structural and MEP models combined in Navisworks to identify and resolve clashes before construction begins. Coordination is run discipline by discipline with clash reports and resolution logs shared back to your project team, reducing field change orders and RFIs on Illinois commercial, industrial and institutional projects where multiple trades are modeling in parallel on tight schedules.

SVC 05

Scan-to-BIM & Point Cloud Modeling Illinois

Laser scan point cloud data converted into accurate 3D BIM models for renovation, retrofit and historic Illinois buildings where as-built conditions must be captured precisely before design work begins. Point clouds are registered, cleaned and modeled to the LOD your design or facility-management team requires, giving architects and engineers a reliable existing-conditions model instead of relying on outdated original drawings.

SVC 06

As-Built BIM Modeling Illinois

As-built BIM models updated to reflect actual field conditions and construction changes, delivered for owner records, facility management and future renovation planning. Models capture what was actually built rather than what was originally designed, giving Illinois owners, GCs and facility teams a dependable model of record for maintenance, space planning and future capital projects long after substantial completion.

SVC 07

BIM Shop Drawings & Fabrication Modeling Illinois

Fabrication-ready BIM models and derived shop drawings for structural steel, precast, millwork and MEP fabricators, detailed to AISC, AWS and trade-specific fabrication standards. Models are coordinated with the federated project model before being handed off to fabrication shops, keeping piece marks, connection details and dimensions consistent between the coordinated model and the shop floor.

SVC 08

4D BIM Scheduling Illinois

BIM models linked to the construction schedule so project teams can visualize sequencing, phasing and site logistics before work begins. 4D simulations help GCs and owners identify schedule conflicts, evaluate phasing alternatives and communicate construction sequencing to stakeholders on complex, multi-phase Illinois projects with tight occupied-site or logistics constraints.

SVC 09

5D BIM Cost Estimating & Quantity Takeoff Illinois

BIM models linked to cost data for quantity takeoff, budget tracking and cost forecasting through design and construction. Model-derived quantities give estimators and owners a more accurate, continuously updated cost picture than manual takeoff from 2D drawings, supporting budget decisions at each design milestone on Illinois commercial and industrial projects.

SVC 10

Revit Family Creation & Content Modeling Illinois

Custom Revit families and parametric content built to manufacturer specifications or project-specific requirements, filling gaps where standard library content doesn't match your design. Families are built with the correct parameters, materials and level-of-detail for their intended use, keeping your firm's model libraries accurate and consistent across multiple Illinois project teams.

SVC 11

BIM Construction Documentation Illinois

Construction document sets generated directly from coordinated BIM models, including plans, sections, elevations and details formatted for permitting and bidding. Documentation stays synchronized with the model, so revisions made during coordination automatically carry through to the drawing set rather than requiring separate manual updates across multiple disconnected files.

SVC 12

BIM Facility Management & COBie Modeling Illinois

As-built models structured with COBie data for handover into facility management and asset management systems. Equipment, warranty and maintenance data is embedded at the appropriate LOD, giving Illinois owners and facility teams a model that supports operations and maintenance from day one of occupancy rather than a design model with no operational data attached.

SVC 13
