Harness your building information from design to decommissioning


Building Information Modeling (BIM) technologies have given rise to high expectations within the community of AEC professionals, yet, to date, their outcome in terms of cost-benefit ratio and return on investment is still debatable. This is because BIM technologies are still largely seen as a fancy tool limited to visualizing facilities in 3D rather than the foundation for a collaborative workflow.

Based on lessons learned for past and ongoing projects, Groupe FIT provides BIM solutions and services that go beyond merely building a 3D database, but assist land developers, architects, engineers, contractors, facility managers, and industrialists making the best out of BIM technologies for improved collaboration workflow and increased productivity throughout the facility life cycle. These solutions include:


1. Create detailed BIM-enabled 3D models of your projects.

A successful project-level BIM solution begins with a thorough assessment of your project environment in terms of technical specifications, contractual obligations, inputs from other parties (e.g. Architect, Engineer, subcontractors, facility manager, etc.), intensiveness of collaboration, in-house business practices and in-house skills. Based on such assessment, Groupe FIT develops the most adapted and cost-effective BIM model and workflow capable to meet your project objectives. This model can be built from a wide range of methods, used separately or in combination:

  • Check and import 3D models developed by other parties in various formats:

               - IFC (.ifc)
               - 3DXML (.3dxml)
               - Rhino 3D (.3dm),
               - AutoCAD Revit (.rvt),
               - Naviswork (.nwd),
               - Tekla BIMSight (.tbp),
               - Tekla Structures (.tsc),
               - VectorWorks (.vwx),
               - Microstation (.dgn)
               - ACIS (.sat)
               - and many more formats...
  • Conversion of 2D CAD design drawings into 3D models (“CAD-to-BIM”)

  • 3D laser scanning of already partly built facilities (“Scan-to-BIM”)

               - Static or dynamic 3D laser scanning for terrestrial structures
               - UAV-mounted 3D laser scanning for aerial structures
               - ROV-mounted 3D laser scanning for subsea structures
               - Conversion of point clouds into 3D objects 

 

2. Detect and resolve spatial clashes between trades 

Collisions between technical trades - such as a water pipe intersecting a steel beam, or a bottom of air duct falling below the designed false ceiling level – are among the major sources of reworks and delays in AEC projects. To assist project managers with mitigating such risks of rework and delay, Groupe FIT offers spatial coordination services that facilitate the systematic detection and resolution of clashes between trades.

Spatial coordination aims at analysing the spatial relationship between various the 3D objects of the BIM model, detect clashes and re-routing and moving objects of the BIM models to avoid such clashes while meeting the project specifications and performance criteria. Groupe FIT adopts an interative and collaborative approach with a particular emphasis on the following:

  •      the position and size of wall and floor penetrations,
  •      the routing of electrical and mechanical networks, and
  •      the position of terminals (fixtures, outlets, grilles and diffusers, etc.)

 

3. Validating construction methods and schedule (BIM 4D).

By adding a “time” dimension to 3D objects – for example the planned date of installation of a concrete slab, a column, a beam, a pipe segment, a fitting, or a piece of equipment – BIM technologies enhance the review and validation of construction methods and construction schedule, and turns BIM into an efficient coordination tool. If needs be, BIM model can be upgraded to include time-dependant construction logistics such as cranage, shoring, scaffolding and forming and enable the early detection of “time clashes”.

Groupe FIT works hand in hand with construction and facility managers to:

  • identify construction or maintenance scheduling requirements,
  • inventory and retrieve time-sensitive information to be added to the BIM objects – e.g. planned and actual date of installation, date of next of inspection, guarantee expiry date, etc. and
  • visualize and validate simulated construction operations
 
4. Estimate material take-off and project costing (BIM 5D) 

As projects are becoming architecturally and technically more complex, conventional quantity survey techniques have reached their limit and generate an unacceptably high level of errors and omissions. Groupe FIT is taking stock of BIM potentialities to propose innovative, comprehensive and real time material take-off calculation and budgeting, automatically generated from the project 3D model and the most updated construction cost books.

Groupe FIT customizes your BIM tool to deliver material take off and pricing estimate according to your format requirements – for example, CSI MasterFormat 1995, CSI MasterFormat 2014, or any other format you may specify.

 
5. Upgrade your BIM into a facility management tool (BIM 6D) 

Through BIM technologies, general contractors are in a position to hand over a clean set of data and documents pertaining to the freshly commissioned facilities to the Facility Manager. However, experience gained by Groupe FIT shows that this construction legacy seldom meets the Facility Manager's technical and functional requirements. To work around this issue and make the best out of BIM technologies, Groupe FIT ensure a smooth transition between construction phase and facility management phase by upgrading the building information model inherited from the construction phase into a turnkey facility management tool making it easier for facility managers to plan, budget and monitor preventive maintenance operations throughout the facility life cycle.  In that respect, Groupe FIT services include:

  • Scanning technical, contractual and commercial paper documentation submitted by manufacturers or subcontractors (e.g. cut-sheet specifications, maintenance/operations manual, warranties, or catalogs of spare parts) and creating hyperlinks to easily retrieve such documentation directly from the BIM interface

  • Extracting and digitizing strategic capacity and performance alphanumeric information from paper documentation to facilitate indexation, queries and further analysis.

  • Export BIM objects' data into a digital format that is fully interoperable with most facility management software (FM) already used in the facility management industry.
