A new Digital Component Library (DCL), which houses digital content like 3D Building Information Modelling (BIM) models, will be used for the first time on Highways England's smart motorways programme.
The DCL was put together by Costain's Faris Mahder, a graduate BIM technician, who was tasked with creating, delivering and managing it for Highways England.
The library currently contains over 80 digitally modelled components across several design disciplines such as gantries, vehicle restraint barriers and MS4s. These modelled components represent an asset through various stages of a project's lifecycle and the library will be continuously updated as new components are brought online.
The aim of the DCL is to reduce the amount of time and resources spent on recreating digital content on each Highways England project. The benefits of the DCL includes reducing the amount of time and resources spent on recreating content; aids in creating an effective communication tool for project team briefings and consultation with stakeholders; early engagement with suppliers bringing greater confidence in nailing down lead times and the associated costs; and early clash detection giving project teams an effective influence on design options, therefore minimising the risk of a prolonged programme.
'The aim of the DCL is to reduce the extensive effort spent recreating content amongst project teams. The value for Highways England is in generating project information models more rapidly and at an earlier stage in a project lifecycle. The DCL will act as one version of truth, through the availability of digital contents from the highways supply chain,' said Faris.
Knowing how to use BIM is now mandatory on all public sector contracts, including the highways sector. BIM is a framework which enables a collaborative way of working, underpinned by digital technologies which unlock cost and time efficiencies through the design, construction and maintenance of an asset.
The library will initially be adopted and piloted on the smart motorways programme (SMP), where it will be rolled out to allow their delivery partners to exercise their choice of tools when creating digital contents.
The smart motorway scheme is part of a £15 billion government investment that Highways England is delivering between now and 2021, which will see 292 extra lane miles added to motorways. The hard shoulder will be converted to a traffic lane and signing and technology will tell drivers what speed to drive at, if lanes are blocked or closed and about incidents up ahead.
'In the smart motorways programme, there is a huge drive towards standardisation of assets and features commissioned within all projects. The DCL reflects this drive but it doesn't remove the responsibility of the designer to provide a safe, innovative and buildable solution,' adds Faris.
