Project Overview
The Client for The International Quarter was the developer and principle contractor for the scheme and their main necessity for BIM is to capitalise on the expected project construction cost savings, whole life cost savings and benefits from Asset Information Modelling for this major investment project.
Without the need to invite principle contractors to tender or offer a response to their approach to the project information management or to demonstrate the supplier’s proposed approach, capability, capacity and competence to meet the EIR, a very basic Employers Information Requirement document was developed as more of a basic BIM guide to aid supply chain management. From this EIR the project Pre-Construction BIM Execution Plan was developed early in the scheme and contained more useful and usable information for the BIM workflow.
As the scheme developed a formal Post-Contract BIM Execution Plan was developed and used as the significant BIM document for the project.
At the time of ONE’s appointment this BEP was well defined and used by a significant number of project team members and suppliers as well as incorporated for all of One’s commissions and appointment documents. All models originated by One were produced, developed and co-ordinated in accordance with the requirements of this BEP.
ONE had to demonstrate a high level of competency using Lendlease’s Supply Chain Capability assessment questionnaire. With extensive levels of BIM involvement, One was able to simply demonstrate compliance and exhibit One’s proficiencies to supply this major project.
As our appointment to assist Lendlease was to manage and co-ordinate specific areas within the project our Task Information deliverables needed to be more fluid than that of a standard TIDP schedule, which we were happy to work with and deliver to Lendlease when and where required.
LOD varied with each scope of works package but covered a wide range of LOD 200 to LOD 400 and our data rich models were used for a variety of different purposes including 4D and 5D programming and sub-contractor tendering purposes.
The projects selected CDE was BIW’s Conject extranet solutions.
Classification system SFG 20 was used for asset information requirements for all mechanical and electrical components.
The modelling and BIM tools used for the project were Revit 2015 and Navisworks Manage 2015 in accordance with the BEP, native file formats requested.
Navisworks Manage software was the platform to federate, view and report items for discussion and resolution within collaboration and co-ordination meetings.
Full COBie levels of information were deemed excessive by the Client and so, for the Asset Information Requirements and Level Of Information required a simplified list of 21 datasets and information were agreed in the BEP.
