THE BIM
REVOLUTION

The emergence of BIM and management of data it contains now make it possible to design, construct and operate projects more reliably, more quickly and more cost-effectively.

At Bouygues Construction, a global player in construction and services, we are convinced that BIM plays a major role in going over to more industrial construction methods and represents the future and a major source of progress for all our stakeholders.

Our Forward Planning, R&D and Techniques Departments at Bouygues Construction propose a long-term vision, preparing tomorrow’s benchmarks today.

Welcome to the BIM world!

BIM : a 3D representation of all data making it possible to design and construct a project and simulate its behaviour.

BIM (Building Information Modeling) a process by which this data is managed throughout the project’s life-cycle.

THE BIM GENERATION, The digital-model revolution

BIM :

AN EVOLVING TOOL

Sustainable construction implies a fresh way of looking at the way industrialists have to design, construct and operate their projects.

To achieve this, Bouygues Construction R&D teams are working to optimise and deploy BIM so that it becomes a genuine performance lever for staff, partners and, naturally, the Group’s clients.

In five years, the Research, Development and Innovation Department at Bouygues Construction has launched ten or so BIM-based projects, many of which are today operational.

BETTER DESIGNING THE PROJECT

UPSTREAM

Optimising accurate forecasting at the design stage, BIM is clearly an efficient decision-making tool.

Stakeholders can visualise the future building with a greater sense of reality than is the case with traditional plans, therefore helping them better grasp the global project. Project costs are also optimised, since associating detailed price schedules with BIM helps fine-tune cost forecasting.

Beyond purely budgetary considerations, BIM becomes the sole place where all data required for carrying out the project is recorded, thereby guaranteeing data coherence.

Last but not least, BIM makes it possible to anticipate challenges and come up with solutions, enhancing worksite organisation and forestalling any nasty surprises.

Augmented reality and virtual reality are today integrated into Bouygues Construction’s commercial bids.

Faire les bons choix

MAKING

THE RIGHT CHOICES

Using augmented reality and BIM enable the right choices to be made from the word go, with the help of simulations, tests and representations that are absolutely realistic and precise.

From the client’s point of view, the visual rendering of the 3D model makes it possible to design a summary pre-project interactively with the project team.

From the project team point of view, BIM helps design difficult areas such as drainage systems on structures or interactions between the various items in a building... and makes it easier to visualise geometry in complex architectural works.

Ramby: augmented reality helping our clients

Mieux comprendre

BETTER UNDERSTANDING

THE PROJECT

BIM provides better global vision of projects. For the client, neighbourhood residents, future occupants but also site workers, BIM makes it possible to visualise future buildings much more concretely than on plans and have a clearer insight into the project.

Augmented reality and virtual reality, which have been the focus of many research projects for several years, are today built into Bouygues Construction’s commercial bids. These tools make it possible to go into a finished building and change things with a simple click in real time: materials (floor, wall and ceiling), configuration of premises, furnishings, external lighting (sun/clouds/night) etc.

OPTIMISING COST ESTIMATION

FINANCING AND MARKETING

5D is the process of integrating the budgetary dimension of a project into the 3D model. Associating detailed price schedules with BIM helps fine-tune cost forecasting.


HOW DOES IT WORK ?

Financing and marketing are made easier since prices are guaranteed and pegged as closely as possible to reality.

20 pour cent

According to UK government sources, using BIM can help reduce current building costs by 20%.

GUARANTEEING COHERENCE

OF DATA

BIM is the sole infrastructure where all data required for carrying out the project is recorded,. This pooling of data avoids repetition and risks of incoherence as the building is developed.
Data which is entered by a person involved in the project automatically impacts everything, therefore immediately identifying interactions between various models.

BETTER CONSTRUCTION

Our professions are evolving rapidly against a structurally-changing backdrop: buildings are being transformed, but so are spaces, usages and relations between the structures in the same facility. BIM is a valuable device for coming to grips with this complexity, facilitating fluid exchanges and logistics.

BETTER ORGANISING THE WORKSITE

INTEGRATING THE TIME FACTOR

BIM makes it possible to go beyond 3D digital construction.
The process takes into account key factors for always being as close as possible to reality, therefore significantly simplifying logistics.

The time factor (4D) is integrated via a planning tool, with the aim of visualising project evolution step by step and checking that the schedule is coherent.

TWO MAJOR AIMS :
1. Presenting the global execution of the project to the client, to reassure him that lead times have been properly understood; associating an in-depth schedule to a detailed model in a precise space, such as angled roof beam casting on very high sites.
2. Anticipating supply needs and modelling storage space facilities to optimise logistics in real time.

ANTICIPATING

CHALLENGES

This is one of BIM’s major benefits. It enables project teams to visualise technical points and interfaces between several building items upstream, instead of discovering them as the site progresses.

In building, complex interactions are shown up more clearly.

On complex civil engineering projects, such as nuclear power plants or large-span viaducts, BIM helps build exceptionally dense reinforcements for the structure.

BETTER EXPLOITATION

BIM does not stop when the project is delivered. On the contrary, it is when the building is operated and managed, or even when updating it is envisaged after a few years, that the system reveals all its benefits.

On a finished building, BIM enhances project management and optimises existing building stock.

75 pour cent

75% of a project’s costs is generated by operation throughout its life.

Fichiers maquette numérique

Delivered with the project, the DOE (dossier de l’ouvrage exécuté – file of work carried out) is, in the client’s eyes, the main facility management tool. The DOE centralises and exhaustively lists data required for project management.

The facility manager can walk virtually throughout the building and click on any item to obtain all related information. BIM is becoming essential for managing contractual commitments, energy consumption, availability and sustainability of technical equipment.

guillemets rouges haut bimgeneration BIM is going to become the main FM tool. Its applications in our professional sector are multiple: monitoring energy comfort and consumption, equipment up-time, scheduling preventive maintenance and dialogue with our clients. guillemets rouges bas bimgeneration

Anticiper et simuler l'évolution de l'ouvrage

ANTICIPATING AND SIMULATING

PROJECT EVOLUTION

Beyond maintenance, buildings must sometimes evolve to adapt to user usages. With BIM, these future evolutions are made easier.

From the design outset, fittings and layouts must be imagined which will enable new usages to be integrated that are adapted to the environment and optimise project use.

BIM will help construct these modular and multifunctional buildings, simulate such evolutions and carry them out.

MANAGING

EXISTING BUILDING STOCK

Integrating real estate asset management tools in BIM was developed in the United Kingdom and became known as "6D". Asset management represents the future for BIM, capable of supplying a single list of all data linked to real estate assets.
For Bouygues Construction clients, and in particular local authorities, this is a major challenge. In order to make savings and meet environmental energy requirements, they inevitably need more fine-tuned knowledge of their assets.

THE CHU OF AMIENS

(FRANCE)

Four Bouygues Construction subsidiaries took part in building the Amiens CHU Hospital Centre.

WHY BIM ?

From 2009 to 2011, eleven people worked on BIM over several stages :

  • Analysing site needs, defining human and material means, dividing up into sub-projects.
  • Creating tools according to families (types of wall, doors, chassis, terminals…), modelling tasks (concrete, partitions, rooms…)
  • Producing documents from BIM: location plans, detecting conflicts, real-time site progress, 3D views for validating purposes...

IN THE PROGRAMME :
bringing together the hospital in the north of Amiens and several of the town’s establishments onto a single site.

SPORTS HUB

(SINGAPOUR)

Covering a 35-hectare site at the heart of the City-State, the huge Sports Hub complex which will be delivered in 2014 could host Olympic Games.

INFRASTRUCTURES

  • a 55,000 capacity stadium
  • an aquatic centre
  • a 3,000 capacity multisports complex
  • an Olympic swimming-pool featuring 6,000 places
  • a pool for aquatic games and 41,000 m² of commercial areas

These facilities are housed in five buildings around the stadium, whence the need to ensure coordination between the various project players.

THE DATA CENTER

IN PANTIN (FRANCE)

Three Bouygues Construction subsidiaries (Sodéarif, Brézillon and Bouygues Energies & Services) built an 11,400-m² data center in Pantin (Seine-Saint-Denis) for world webhosting leader Equinix..

Built in 3 phases, technical facilities were designed to provide an optimum level of reliability and uptime for 24/24 and 365/365 operation.

WHY BIM ?

  • To work on highly advanced electrical and thermal civil engineering:
    redundant electrical supply chain, ultra-controlled air quality and temperature with a ceiling of 23°C.

The model was used at two stages of the project :

During the pre-project phase, to carry out syntheses between the various lots: architect, structure, high- and low-current electricity, air-conditioning-ventilation-heating.

During the execution phase, for explanatory technical reports which made it possible to clearly visualise proposed technical modifications.
