- The Handover Problem Today
For all the digital progress the construction industry has made, handover remains one of its most fragile moments. It’s the point where years of design, coordination, procurement, and on‑site decision‑making must be distilled into a package that operations teams can actually use.
But too often, handover is rushed, inconsistent, or incomplete. Facilities teams inherit:
- Models that don’t reflect what was actually installed
- PDFs and spreadsheets scattered across multiple folders
- Missing commissioning data
- Unverified asset information
- Conflicting versions of drawings and models
The result is predictable: operations teams spend months recreating information that should have been delivered on day one. Maintenance becomes reactive instead of planned. Asset registers are rebuilt manually. And the building’s digital foundation starts with gaps that only widen over time.
The industry talks a lot about “closing the loop” — but poor As‑Built data is exactly where the loop breaks.
- What As‑Built BIM Should Really Deliver
A true As‑Built BIM model is not a tidy version of the design model. It is a verified record of what was actually constructed — spatially, technically, and operationally.
High‑quality As‑Built BIM should deliver:
- Accurate geometry that reflects final installation, not design intent
- Verified asset data including serial numbers, commissioning dates, and maintenance requirements
- Coordinated services showing real‑world routing, clearances, and access zones
- Linked documentation such as O&M manuals, warranties, and product data
- A single, navigable source of truth for facilities teams, not a collection of disconnected files
When done properly, As‑Built BIM becomes the backbone of building operations. When done poorly, it becomes a digital liability — a model that looks impressive but can’t be trusted.
- Why This Matters for Smart Buildings & Digital Twins
Smart buildings and digital twins depend on one thing above all else: accurate, structured, reliable data.
If the As‑Built model is wrong, everything built on top of it inherits the same flaws:
- Sensors are mapped to incorrect locations
- Asset monitoring is unreliable
- Predictive maintenance models fail
- Energy optimisation tools use inaccurate baselines
- Space utilisation analytics become misleading
A digital twin is only as intelligent as the data it receives. If the As‑Built model is incomplete or inaccurate, the digital twin becomes a digital illusion — impressive in theory but disconnected from reality.
This is why owners and operators are now demanding higher‑quality As‑Built deliverables. They understand that the handover model is no longer a closeout formality; it is the foundation of the building’s entire digital lifecycle.
- How Draftech Can Manage and Produce Your As‑Built Models
A. A Proven Process That Removes the Guesswork
Most handover issues stem from inconsistent data, unclear responsibilities, and late‑stage scrambling. Draftech solves this by applying a structured, repeatable workflow that ensures As‑Built models are accurate, verified, and aligned with operational needs — not just design intent.
This includes:
- Early engagement to define As‑Built requirements
- Clear modelling standards and naming conventions
- Coordination with trades to capture real installation changes
- Progressive updates instead of end‑of‑project rush
- Final verification against site conditions and commissioning data
The result is a model that reflects the building as it truly exists — not as it was originally designed.
B. Verified Geometry and Asset Data You Can Trust
Draftech’s team specialises in high‑accuracy mechanical, electrical, hydraulic, and fire services modelling, ensuring that every system is represented correctly.
We deliver:
- Corrected geometry based on redlines, RFIs, site changes, and field measurements
- Fully verified asset information (serial numbers, model numbers, commissioning dates, warranty data)
- Accurate routing, access zones, and maintenance clearances
- Integration of O&M documentation directly into the model
This eliminates the common “trust gap” between construction and operations teams.
C. Coordination That Reduces Risk for Owners and FM Teams
Poor As‑Built data creates operational blind spots. Draftech closes these gaps by ensuring:
- All services are coordinated as installed
- Clashes and access issues are resolved before handover
- FM teams receive a model that supports maintenance, not hinders it
- Asset registers and schedules are aligned with the model
Owners gain a reliable digital foundation that supports long‑term asset performance.
D. Deliverables Ready for Smart Buildings and Digital Twins
Because Draftech works across BIM, digital engineering, and fabrication‑level modelling, our As‑Built outputs are structured for future use — not just archival.
We prepare models that are:
- Structured for integration with FM platforms
- Ready for IoT sensor mapping
- Suitable for digital twin environments
- Built to support lifecycle asset management
This ensures the building’s digital ecosystem starts with clean, accurate, and connected data.
E. A Partner Who Understands the Entire Project Lifecycle
With 25 years in the AEC industry, Draftech brings deep experience across design, coordination, construction, and operations. We understand the pressures on contractors, the expectations of owners, and the needs of facility managers — and we bridge those worlds with clarity and precision.
Whether you need full As‑Built BIM production, verification of contractor models, or a complete digital handover package, Draftech provides the expertise and structure to deliver it right the first time.
As‑Built BIM is no longer just a project closeout deliverable — it is becoming the critical link between construction and building operations. When models are verified and maintained accurately, they preserve the building intelligence that is so often lost during traditional handover. This shift is enabling smarter asset management, better facility performance, and more reliable digital twin environments.
