BIM

Eric Wright Construction is delighted to announce the launch of BIM on several projects starting in August 2012, well ahead of government targets; placing the company at the leading edge of digital construction delivery.

We have already rolled out BIM software to our in-house designers, design managers, estimators and surveyors; while our design consultants and key supply chain partners are introducing BIM systems on their contributions to projects' design and construction.

Our pioneer BIM projects include our own public sector partnership schemes, and developer led projects at:

  • Baron Road Primary School, Blackpool
  • Albion Place, Skipton
  • Blackpool Council Offices
  • Avondale Health Centre, Bolton
  • Nye Bevan Health Centre, Rochdale

Our BIM design partners include AEDAS architects, Nightingales, Booth King Partnership, Arup, Ameon and JRB Associates.

To give it its full title: Building Information Modelling and Management BIM(M) is a managed approach to the collection and exploitation of information across a project. At its heart is a computer-generated model containing all graphical and tabular information about the design, construction and operation of the asset. This model can be modified, analysed and documented faster, more effectively and with reduced risk of error. BIM delivers enhanced accuracy of design for costing and planning, it identifies clashes of structure and services early in the process and allows detailed interrogation of the design for value engineering and analysis of buildability. To achieve these advantages the design must be developed to a high level of detail at an early stage, and every discipline, including subcontractors, must design within the BIM virtual environment.

From the inception of a project our design team works in collaboration, adding components incrementally to the digital model. There are no individual drawings; all information is extracted from the model. To achieve this every member of the design team must use compatible software, and must access a server or cloud based model. Most importantly the team has to make detailed decisions on design and specification right from the start, because the model has to be constructed exactly like the building. The model allows digital components to carry extensive information on specification and dimensions so that scheduling and costing may be rapidly and accurately undertaken.

Information for construction will still be delivered by means of traditional paper drawings, but these will always be generated from the up-to-date model, and the contractor team will be provided with access to the digital model. As contractor, we will manage and control this process. Initially our key advantage will be a proper understanding of the BIM process and how it influences the timing of design decisions. We will be more selective in our appointment of consultants and subcontractors, and we will bring forward the involvement of specialist design subcontractors. To access and interrogate the digital model we operate Autodesk NavisWorks software, to enable clash detection and the production of 3D views. Estimating software is also integrated with NavisWorks to generate schedules and take-offs.

Benefits of BIM

1. Better Outcomes through Collaboration

All project partners - different design disciplines, the customer, contractor, specialists and suppliers - use a single, shared 3D model, cultivating collaborative working relationships. Everyone is focused on achieving best value, from project inception to eventual decommissioning.

2. Enhanced Performance

BIM makes possible swift and accurate comparison of different design options, enabling development of more efficient, cost-effective and sustainable solutions.

3. Optimised Solutions

Through deployment of new generative modelling technologies, solutions can be cost-effectively optimised against agreed parameters.

4. Greater Predictability

Projects can be visualised at an early stage, giving owners and operators a clear idea of design intent and allowing them to modify the design to achieve the outcomes they want. In advance of construction, BIM also enables the project team to realise the project in a virtual environment, rehearsing complex procedures, optimising temporary works designs and planning procurement of materials, equipment and manpower.

5. Faster Project Delivery

Time savings, up to 50%, can be achieved by agreeing the design concept early in project development to eliminate late stage design changes; using standard design elements when practicable; resolving complex construction details before the project goes on site; avoiding clashes; taking advantage of intelligence and automation within the model to check design integrity and estimate quantities; producing fabrication and construction drawings from the model; and using data to control construction equipment.

6. Reduced Safety Risk

Crowd behaviour and fire modelling capability enable designs to be optimised for public safety. Asset managers can use the 3D model to enhance operational safety. Contractors can minimise construction risks by reviewing complex details or procedures before going on site.

7. Fits First Time

Integrating multidisciplinary design inputs using a single 3D model allows interface issues to be identified and resolved in advance of construction, eliminating the cost and time impacts of redesign. The model also enables new and existing assets to be integrated seamlessly.

8. Reduced Waste

Exact quantity take-offs mean that materials are not over-ordered. Precise programme scheduling enables just-in-time delivery of materials and equipment, reducing potential for damage. Use of BIM for automated fabrication of equipment and components enables more efficient materials handling and waste recovery.

9. Whole Life Asset Management

BIM models contain product information that assists with commissioning, operation and maintenance activities - for example sequences for start-up and shut-down, interactive 3D diagrams showing how to take apart and reassemble equipment items and specifications allowing replacement parts to be ordered.

10. Continual Improvement

Members of the project team can feed back information about the performance of processes and items of equipment, driving improvements on subsequent projects.

Building Information Modelling (BIM) is both a new technology and a new way of working. BIM offers the capacity to address many of the industries failings including waste reduction, value creation and improved productivity.
