Engineering and BIM Consultancy
Engineered to Be Built.
We provide BIM modelling, coordination and shop drawings for infrastructure, landscape and building projects.

The gap
Resolve coordination issues before they reach site.
Many site problems begin as gaps on paper. We review, model and coordinate within the agreed scope so issues are raised and tracked before drawings are issued.
Conflicting information
Drawings contradict each other or the specification, and open questions pile up as Requests for Information (RFIs).
Coordination issues
When disciplines are not coordinated in one model, networks meet at excavation and services clash at installation.
Drawings returned with comments
Shop drawings come back for revision while the programme waits.
Services
What we deliver.
Hire us for one service or for the full agreed scope.
All ServicesBIM Modelling

Deliverables: Coordinated (federated) model · Clash report · RFI register
Shop Drawings
Shop drawings and combined services drawings produced from the coordinated model.
Deliverables: Shop drawings · Combined services drawings · Relevant clash report
Design Review
Review of design drawings before modelling starts, with gaps raised as RFIs.

Quantities and As-built
Model-based quantity take-offs, site support and as-built models.
Deliverables: Quantity take-off · Updated and as-built models within the agreed scope
Why Zentrac
Why teams hand us the hard part.
Review before modelling
Modelling scopes start with a review of the supplied design. Gaps and conflicts go back to you as RFIs before modelling begins.
Coordinate before issuing
Models are checked for clashes in a federated model, and issues are logged and followed up before drawings are issued.
Infrastructure focus
Utilities, roads, landscape and grading are our home ground: eleven infrastructure categories, one coordinated approach.
Your BEP and templates
We work to your BIM Execution Plan (BEP), standards, title blocks and naming conventions.
| Ref. | Interface | Issue | Status |
|---|---|---|---|
| RFI-024 | Stormwater / Water | Crossing level to be confirmed | Raised |
| CL-07 | LV / MV / Irrigation | Clearance in shared corridor | In review |
| RFI-031 | Roads / Grading | Spot levels missing at junction | Answered |
| CL-12 | Sewerage / Telecom | Manhole conflicts with duct route | Closed |
Infrastructure
Eleven infrastructure categories. One coordinated approach.
We model and coordinate utility networks, roads, landscape and canals so conflicts can be identified and resolved before construction starts.

All eleven categories
Select a category to highlight it in the site schematic. Each project defines which categories, roles and deliverables are in scope.
Deliverables
What a coordinated package includes.
A typical package combines a model, the drawings extracted from it and a record of the issues raised along the way. Contents are agreed for each scope.
Discipline model
Models built to the agreed BIM Execution Plan (BEP) and Level of Development (LOD), with clear scope boundaries.
Drawings
Shop drawings and combined services drawings extracted from the coordinated model.
Issue register
Clash reports and a Request for Information (RFI) register that record each issue and its follow-up.
Generic illustrations. They do not represent a specific project.

The Zentrac Track.
Six stages, from review to site support. What we receive is checked; what we hand over is prepared for the next party.
01 Review
We review the supplied drawings and site information and record gaps before modelling starts.
- Input
- Design drawings, specifications, site information
- Output
- Review notes and RFIs
02 Model
We build discipline models to the agreed BEP and scope.
- Input
- Reviewed design, BEP, coordinates
- Output
- Discipline models
03 Coordinate
We run clash checks in a federated model and track coordination issues.
- Input
- Discipline models, coordination rules
- Output
- Clash reports and issue register
04 Drawings
We extract the agreed shop drawings from the coordinated model.
- Input
- Coordinated model, title blocks, drawing list
- Output
- Shop and combined services drawings
05 Quantities
We prepare the agreed model-based quantities and schedules.
- Input
- Measurement rules, agreed model scope
- Output
- Quantity take-offs and schedules
06 Site Support
We support site queries and model updates through to as-built handover.
- Input
- Site queries, verified site changes
- Output
- Updated and as-built models
