B/555 Roadmap (2012 Update)

Design, Construction & Operational Data & Process Management for the Built Environment

Introduction

The purpose of this updated “Roadmap” is to document and describe the activities of the BSI B/555 committee (Design, modelling and data exchange) in the immediate past, current and future in support of delivering clear guidance to the UK industry dedicated to providing and operating built assets. It also supports the vision and mission statement of the committee in the reduction of whole life cost, risk, carbon and the timely delivery of buildings and infrastructure projects. The 2012 Update also incorporates the activities in support of the 2011 HMG BIM Strategy.

To illustrate the process a maturity model has been devised to ensure clear articulation of the standards and guidance notes, their relationship to each other and how they can be applied to projects and contracts in industry.

To simplify the description of technologies and ways of working, the concept of maturity “Levels” has been defined. The purpose of the maturity levels is to categorise types of technical and collaborative working to enable a concise description and understanding of the processes, tools and techniques to be used, thus allowing simple referencing as to where various documents should be applied.

Hurley Palmer Flatt understand Building Information Modelling (BIM) and have been working with digital representations of physical and functional facility characteristics for over a decade. We ensure client’s visions of building and service installations are realised in the early stages of the design process. The origins of BIM are routed within the process and infrastructure industries but first found their way into the building and construction industries in the mid 1980s with the introduction of Graphisofts Archicad package. This was effectively a tool that enabled architects and designers to model buildings in 3D.

It has taken the rest of the construction industry a while to catch up with this technology, but in the last decade the use of BIM technology has increased profoundly and is likely to be considered the norm in the near future, as the benefits are realised.

The release of the government’s construction strategy in May 2011 has helped push the use of the BIM process, requiring all public sector projects to utilise level 2 of the BIM process by 2016.

It is fair to say from an MEP engineering services perspective that the supply chain and contracting sectors need to make a conscious commitment in developments to fully leverage from a BIM philosophy and ultimately its capability.

Working in collaborationSimply put, BIM Level 0 is all about using the right tools – CAD.

At BIM Level 1, Hurley Palmer Flatt is committed to working smarter and harder in collaboration across all of its internal divisions using 2D and 3D models.

For BIM Level 2 and on a wider scale, Hurley Palmer Flatt are one of the industry’s leading building services design engineers. Trusted advisors who have attracted external project partners who in collaboration have collectively built robust building solutions by using industry standard tools on known technologies.

Integrated BIM (iBIM) is the next step and we are ready! We have tested our own internal pilot data system using Deltek and its SQL data server.

This allows us to capture manufacturer’s object information and present detailed object specifications linked to our design models. We are committed to supporting a wider iBIM deployment, as supply chain participation increases over the coming years.

BIM driversMany factors are driving a de facto standard for a best-in-class way of collaboratively working within one’s own environment, and more broadly working in conjunction with all project participants to deliver more intelligently and effectively.

» Economic pressures

» Reducing costs

» Government changes

» Client request

» Reducing site mistakes

» Developed technology

Further developments4D - time Virtual representation of project phasing and sequencing, Plant replacement strategy analysis CFD modelling.

5D - costs Costs allocated directly to design objects that generate analysis and the cost impact for changes.

6D - lifecycle managementEnsuring maximum value is achieved throughout the lifecycle of your asset.

Level 0 CAD - drawings, lines, arcs, text etc.

Level 1 2D / 3D - models, objects, local collaboration

Level 2 2D/3D - models, objects and data with full team collaboration

Level 3 Integrated BIM using single model with multiple users. Fully interoperable data exchange

Client gainsThere are clear gains to be had for clients who adopt a BIM approach for their property portfolio and research suggests these quantifiable gains are demonstrable:

» Up to 40% elimination of unbudgeted change

» Up to 80% reduction in time taken to generate a cost estimate

» Cost estimation accuracy within 3%

» Savings of up to 10% of the contract value through clash detections

INTRODUCTION TO THE WORK STAGES

At Hurley Palmer Flatt we have traditionally worked within the RIBA and ACE work stages when delivering our services for clients.

Since the release of the RIBA work stages (May 2012), which now incorporate the architectural BIM work activities. We have looked at the synergy with our own BIM work activities and demonstrated above where we fit into the life of the model, and reflected in our BIM activity work steps 1-6 overleaf.

We believe this level of service delivery will ensure a fully collaborated design, with the appropriate level of energy monitoring and feedback.

Furthermore, we are aware that RIBA are looking to collaborate more with the wider construction audience in relation to workflows, and our strategy will be adjusted to suit this deliverable once completed.

‘We have looked at the synergy with our own BIM work activities and demonstrated above where we fit into the life of the model’

STEP 1 APPRAISAL » Engage with the BIM team and contribute

to the client

» Discuss and agree level of BIM to be used

» Discuss and agree how hpf will integrate with the master model.

» Discuss and advise the technical software that hpf intend to use

» Advise any specific BIM surveys required from the engineering services perspective.

STEP 2 DUE DILIGENCE » Review model produced by the Architect

and advise any quick wins

» Carry out high level environmental analysis using IES technical software model using data provided by the Architect to build thermal model and inform any further adjustments to maximise energy and carbon reduction benefits.

» Review any prefabrication opportunities for the engineering services

» Review and agree with the BIM team, extent of performance specified elements of the engineering services.

STEP 3 SCOPING WORKSHOP » Attend workshop to review all the

elements discussed at steps 1 and 2 to ensure that the scope of our works is clear and any options are viable

» Discuss and agree any changes to the master model in terms of logistics, prefabrication, plant or riser location etc.

» Agree procedure for clash detection and frequency of uploading to avoid abortive works.

» Agree level of data to be attached to the various objects.

» Agree use of generic or bespoke engineering services design components.

STEP 4 LIVE TESTING » Check that all links are correctly operating

for data sharing and integration.

» Check that the uploading of models and data is working

» Check that the model changes from each member of the BIM team is being received correctly with the data intact.

» Issue areas of engineering service detail to BIM team to facilitate any coordination in critical areas, such as plant rooms, service risers, and service routes.

STEP 5 IMPLEMENTATION » Complete details of thermal model working

closely with other members of the BIM team to maximise energy and carbon reduction with the IES modular design tools.

» Complete design using technical software for all engineering service disciplines and feed this into the detailed design model to finalise all objects with tagged information to allow input to the relevant schedules (COBie or otherwise).

» Discuss and agree any modifications necessary to overcome any clashes detected

» Attend ongoing workshops to ensure the collaboration process is successful and the collective individual models sit within the master.

» Enable the completed engineering services model to be usable for the Contractor for his development to fabrication/construction stage.

STEP 6 MONITORING AND FEEDBACK » Review energy data obtained after a seasonal usage of the

building to assess actual data against the intended design energy consumption and building operation.

» Advise any issues or anomalies found that could be as a result of poor engineering services operation, staff training or any immediate faults found.

Our BIM strategyWe pride ourselves on fully appreciating the client’s objectives. From day one our BIM Manager will employ a six step BIM strategy, starting with a full appraisal briefing session to understand what our clients goals really are. Each milestone is manageable and our BIM Technicians will ensure a seamless stepped approach to building implementation. Once the project goes live, we provide visibility through our monitoring and feedback to ensure that our client’s aspirations are fully met for the lifecycle of the facility.

Core Maturity Model Model used within BS 8541 to define levels of BIM as follows:

0 - Unmanaged CAD probably 2D, with paper (or electronic paper) as the most likely data exchange mechanism

1 - Managed CAD in 2 or 3D format using BS 1192:2007 with a collaboration tool providing a common data environment, possibly some standard data structures and formats. Commercial data managed by standalone finance and cost management packages with no integration

2 - Managed 3D environment held in separate discipline “BIM” tools with attached data. Commercial data managed by an ERP. Integration on the basis of proprietary interfaces or bespoke middleware could be regarded as “pBIM” (proprietary). The approach may utilise 4D programme data and 5D cost elements

3 - Fully open process and data integration enabled by IFC/IFD. Managed by a collaborative model server. Could be regarded as iBIM or integrated BIM potentially employing concurrent engineering processes

Data Drops A level of data as yet undefined that will be the output from the BIM process at various stages. RIBA have identified data drops at stages B, C, E, G, K and L
