Package · CAD&BIM Engineering & BIM
From engineering to construction documents.
Engineering studies, BIM modelling, drawing production and BIM management for building and infrastructure projects — with a clearly defined scope, deliverables and responsibilities for every assignment.
Reference project
Kikot hydropower dam: associated works in 3D.
Architectural and engineering studies of the dam's associated works, presented from the project's digital model.
Our principle
Study, model, document: three jobs, three responsibilities.
We keep these services separate so you know exactly what you order, what you receive and who is responsible for it.
Is the solution right?
Assumptions, calculations, design, justification.
Produces: calculation notes, reports.
What does it look like?
3D representation of the chosen solution and its information.
Produces: models, federated models, IFC.
How is it built?
Communicating the solution so it can be approved and built.
Produces: drawings, details, schedules.
A BIM model can faithfully represent a solution that has not been calculated or checked. Modelling reproduces the input data provided; on its own, it does not validate the design or its technical compliance.
Validation is the role of engineering studies and of professionals holding the required skills, qualifications and authorisations.
Our 4 services
Order exactly what your project needs.
01 — Engineering studies and calculations
Technical analysis · Design · Justification of solutions
Study assignments requiring specific engineering skills, within the contractual scope and the qualifications of the people involved.
Architecture
- Architectural design studies
- Needs analysis and functional space planning
- Architectural feasibility studies, depending on the assignment
- Definition of architectural solutions
Structure
- Reinforced-concrete, steel or other structural studies
- Load calculations and load combinations
- Design of structural members
- Stability checks and justification of solutions
- Calculation notes and technical reports
MEP
- Electrical installation studies and sizing
- Plumbing and drainage network calculations
- Ventilation and air-conditioning sizing
- Technical networks and equipment studies
- Calculation notes and supporting documents
Infrastructure
- Technical studies within the agreed scope
- Road, utilities and civil works studies
- Calculation and design of structures, by qualified specialists
- Associated reports and technical documents
Possible deliverablesStudy reports, calculation notes, design assumptions, design drawings, supporting documents.
02 — Digital modelling and BIM
3D modelling · Technical data · Digital coordination
Creating and developing digital models from the project's drawings, studies, input data and specifications.
Architecture
- BIM modelling of buildings
- Walls, slabs, doors, windows, roofs, components
- Model organisation and information integration
- Level of detail and information as required
Structure
- Foundations and load-bearing elements
- Columns, beams, slabs and steel structures
- Integration of data from structural studies
- Model preparation for coordination
MEP
- Electrical networks and equipment
- Plumbing and drainage networks
- Ventilation and air conditioning
- Equipment integration and spatial coordination
Infrastructure
- Roads, bridges and structures
- Civil works projects based on available data
- Use of survey and geospatial data
- Models fitted to project objectives
Possible deliverablesNative models, federated models, IFC files, 3D models and digital data agreed in the contract.
The model matches the input data provided, at the agreed level of detail. It does not check the design, stability or regulatory compliance of the solutions shown.
03 — Drawings and technical documentation
Drawings · Details · Schedules · Construction documents
Producing, updating and organising the graphic and technical documents needed for studies, coordination and construction.
Architecture
- Floor plans, sections and elevations
- Architectural details
- Door and window schedules
- Schedules and drawing sets
Structure
- Formwork drawings
- Rebar drawings, from validated studies and design data
- Construction details
- Schedules and production documents
MEP
- Network and equipment layout drawings
- Electrical distribution drawings
- Plumbing, ventilation and air-conditioning drawings
- Diagrams and technical details within scope
Infrastructure
- Road and site layout drawings
- Long and cross sections from study data
- Structure drawings and technical details
- Combined and graphic documents
Possible deliverablesDWG and PDF files, drawings extracted from models, details, schedules and document sets.
Rebar drawings and construction documents translate studies and designs validated upstream; producing them graphically does not replace that validation.
04 — BIM management and coordination
Strategy · Standards · Processes · Quality control
Structuring and coordinating the digital production of all project stakeholders.
- Defining the BIM strategy
- Writing the BIM Execution Plan (BEP)
- Modelling and exchange conventions
- Production and approval processes
- Model federation
- Clash detection and tracking
- Quality control of models and deliverables
- Team support and update tracking
Possible deliverablesBEP, BIM conventions, federated models, clash detection reports, quality-control reports, correction tracking sheets.
Clash detection checks geometric consistency between models; it is not a check of the calculations.
Service options
A targeted service or a full assignment.
Pick one option or combine them. For each, we state the input data and who is responsible for the calculations.
Engineering studies
Technical studies, calculations and design.
Input data: brief, site data, assumptions.
Responsibility for calculations: by the qualified people named in the contract.
BIM production
Modelling of defined solutions and integration of study data.
Input data: drawings, studies and calculation notes provided.
Responsibility for calculations: remains with the author of the studies.
Documentation
Production of drawings, details and technical files.
Input data: validated models and designs.
Responsibility for calculations: remains with the author of the studies.
Integrated assignment
Studies, BIM modelling, coordination and documentation.
Input data: brief and project data.
Responsibility for calculations: shared as set out in the contract.
Our commitment
Clear assignments, clear responsibilities.
For every project: assignments, input data, deliverables, responsibilities and approval procedures set out in writing.
A BIM model delivered by CAD&BIM is…
- True to the drawings, studies and specifications provided
- At the agreed level of detail and information
- Organised, data-rich and exportable (IFC)
- Geometrically coordinated between trades
…but a model on its own is not
- A calculation note or a design
- A stability or compliance check
- A validation of studies supplied by others
- A document for regulatory signature
Calculation studies, technical checks and documents requiring regulatory approval or signature are entrusted to professionals with the required skills, qualifications and authorisations.
How it works
Four steps, from scoping to delivery.
Scoping
Scope, option A–D, disciplines, level of detail and information.
Input data
Inventory of documents provided, their author and approval status.
Production
Studies, modelling and documentation, with agreed progress reviews.
Approval and delivery
Internal checks, approval by competent parties, file delivery.
