Intelligent 3D Models
Unlike traditional CAD drawings, BIM models carry parametric data - materials, dimensions, costs, and system properties - enabling smarter decisions at design, construction, and operational stages.
Precise 3D coordination, clash detection, and construction-ready documentation for office towers, retail centers, mixed-use developments, and corporate campuses - reducing risk at every project phase.
Drafting Buddies provides BIM, CAD drafting, and construction documentation services for a wide range of commercial developments, including office buildings, retail centers, mixed-use properties, corporate campuses, business parks, and commercial complexes. We work closely with architects, engineers, contractors, developers, and project managers to deliver accurate drawings and coordinated BIM models that support every phase of a project, from planning and design through construction and facility handover.
Our team assists with both new commercial construction and renovation projects by producing detailed drafting packages, BIM models, shop drawings, coordination drawings, and as-built documentation. Whether the project involves a single office fit-out, a retail expansion, or a large multi-story commercial development, we create clear and reliable construction documents that help project teams make informed decisions and maintain project consistency.
Commercial projects often require coordination between architectural, structural, mechanical, electrical, and plumbing systems while meeting strict schedules and budget requirements. Accurate documentation plays a critical role in reducing rework, improving communication, and supporting efficient project delivery. Our workflows are designed to identify potential coordination issues early, streamline design collaboration, and provide documentation that contractors and stakeholders can confidently use throughout construction.
Using industry-standard BIM and drafting technologies, we help commercial project teams improve design coordination, enhance project visibility, and maintain consistency across all project documentation. The result is a more organized construction process, fewer on-site conflicts, and documentation that supports successful project execution while meeting the functional and operational goals of modern commercial buildings.

Understanding BIM
Building Information Modeling (BIM) is not just 3D design - it is a data-rich digital process that connects every discipline, phase, and stakeholder across your commercial project's lifecycle.
Unlike traditional CAD drawings, BIM models carry parametric data - materials, dimensions, costs, and system properties - enabling smarter decisions at design, construction, and operational stages.
Architectural, structural, and MEP systems are combined into a federated model. All consultants work from a single source of truth, eliminating coordination gaps and drawing conflicts.
From concept design to facility management, BIM data persists - providing accurate takeoffs during procurement, commissioning records after handover, and renovation baselines years later.
Authorities increasingly accept BIM submissions for permit approvals. Automated clash detection eliminates conflicts between structural elements and MEP systems before they reach site.
Model-based quantity takeoffs directly feed into cost estimates and BOQ preparation. 4D scheduling links model elements to programme, surfacing sequence issues early in the design stage.
BIM enables energy performance analysis, daylight simulation, and material lifecycle assessment - supporting green building certifications like LEED and BREEAM for commercial projects.
Our Process
A structured, communication-first workflow that keeps your project on schedule and your team informed at every stage.
We review your drawings, RFP, and BIM Execution Plan requirements. We confirm LOD, software formats, and deliverable schedule with a detailed scope of work.
We prepare or align with your BEP – defining modelling standards, naming conventions, shared coordinates, and inter-discipline exchange protocols.
Architectural, structural, and MEP models are built by specialists in Revit, Tekla, or MagiCAD – linked and federated in Navisworks for coordination.
Automated and manual clash detection across all disciplines. A Clash Detection Report with RFI logs is shared; priority conflicts resolved with your design team.
Coordinated construction drawings, shop drawings, BOQs, and model files are packaged and issued – ready for permit submission and site construction.
Post-construction, we update the model to reflect built conditions using site surveys and point cloud data – delivering a verified as-built BIM for the owner's records.
Complete Service Range
Every BIM service your commercial project needs - from early-stage concept modeling to construction-ready coordination packages - delivered by engineers with real project experience.
Detailed Revit models covering office floor layouts, core-and-shell documentation, lobbies, and tenant fit-out coordination. Coordinated at LOD 200-400 for design development through construction.
Coordinated structural models for concrete frames, post-tension slabs, and structural steel used in commercial high-rises and podium developments. Shop drawings for fabrication-ready output.
Multi-discipline MEP models for HVAC ductwork, chilled water systems, electrical distribution, fire protection, and plumbing - fully clash-detected and coordination-ready for site fabrication.
Navisworks-based clash detection across architectural, structural, and MEP disciplines. We produce a prioritized Clash Report with resolution proposals and track resolutions through to zero-clash sign-off.
Complete drawing sets extracted from BIM models for permit submission, contractor coordination, and code compliance - plan, section, elevation, detail, and schedule sheets issued in current-revision status.
Verified as-built BIM models reflecting actual constructed conditions - created from point cloud scans, site surveys, and RFI records. Used for facility management, renovation planning, and ownership handover.
Parametric model-based quantity extractions for all building elements - concrete, reinforcement, steelwork, MEP equipment, finishes. Directly linked to cost estimation and tender preparation workflows.
Detailed BIM models for glass curtain walls, cladding systems, aluminium framing, and architectural feature facades on commercial towers - including unitised panel layouts and glazing schedules.
Conversion of 3D scan data (from existing buildings or site surveys) into accurate Revit or AutoCAD models - supporting renovation design, structural assessment, and heritage documentation.
Common Challenges
Commercial BIM projects face specific technical and coordination hurdles. Our team has encountered - and resolved - every one of these across 500+ projects.
Mechanical, electrical, and plumbing systems compete for limited ceiling void space in commercial floor plates - particularly in service corridors and risers.
Zone-by-zone MEP coordination with priority hierarchy routing and vertical-section clash matrices.
Structural grids, column offsets, and slab edge conditions often conflict with architectural floor plans - especially in high-rise cores and facade interfaces.
Shared coordinates and discipline-specific clash sets; structural model used as federated underlay for architectural coordination.
Commercial projects undergo frequent design revisions - late structural changes, tenant modification requests, and value engineering - that cascade across all disciplines.
Revision-controlled model environment with change log documentation; model is updated in parallel with RFI responses within 48 hours.
Large commercial projects involve 10-20 consultants working across multiple offices, time zones, and software platforms - creating file compatibility and communication gaps.
CDE-based model sharing via BIM 360/ACC with defined IFC exchange protocols and scheduled coordination meetings.
Permit deadlines, contractor mobilisation dates, and phased tenancy schedules demand compressed BIM delivery - without sacrificing model accuracy or coordination depth.
Parallel discipline modeling with daily coordination cycles; dedicated project leads provide direct client access and milestone-driven delivery.
Clients and contractors sometimes specify LOD 400-500 models without understanding the cost and time implications - leading to scope disputes mid-project.
Transparent LOD phasing in our BEP - LOD 300 for coordination, LOD 400 for fabrication zones, LOD 500 for asset-tagged as-built delivery.
