3 Introduction Content Focus Implications for Private / Consultant / Client s Quantity Surveyor (PQS) Changing Role of PQS Impact on Project Management role Impact of more Traditional Roles Barriers to adoption

4 Changing Role of PQS

5 Changing Role of PQS So what can the QS bring to the party? Tradition Measure & Value roles. Fee % mainly generated from BoQ production. 1970/80 s Cost Planning / modelling developed Fee % from BoQ reducing with client demand + new technology Various Surveys present

6 Willis et. al. (1994) Changing Role of PQS

7 Changing Role of PQS Construction sector structural changes IT revolution Client base changes Clients increasing expectations 1999 Cobra Paper (Burnside, K. et. al.) Describes how quantity surveyors are currently addressing these challenges by examining the extent to which how practitioners are developing new and existing services to meet changing client needs and expectations, selling their skills and expertise into new markets, developing different types of relationships with their clients and specialising in niche markets.

9 Changing Role of PQS RICS RESEARCH, Alignment of Professional, Academic and Industrial Development Needs for Quantity Surveyors: The Post Recession Dynamics? (2011)

10 2012 Survey Changing Role of PQS

11 Changing Role of PQS Main Growth areas Management Services e.g. 1. Project Management 2. Risk Management 3. Value Management / Engineering 4. Dispute Resolution 5. Whole Life Costing

13 Impact of BIM on Project Management role

14 Impact of BIM on Project Management role Level 2 (various designers models combined) CONSULTANTS APPOINTMENTS / SCHEDULE OF SERVICES / FEES 1. Ownership of BIM model (Level 2 ) 2. NBS Legal issues: 1. Who is responsible for coordinating the various models (clash detection etc.)? 2. Who can rely on which parts of the model? 3. Quality of BIM model data specifically what s required from each designer / model? 4. Define (& control) Permissible uses of the model 5. Schedule Deliverables from model (i.e. plans, elevation, sections etc.)

15 Impact of BIM on Project Management role Level 2 (various models combined) CONSULTANTS APPOINTMENTS / SCHEDULE OF SERVICES / FEES 3. Master planning - Increased productivity / visualisation of design 4. Software Interoperability:- ArchiCAD or Revit Architecture, Revit Structures or Tekla Structures, Revit MEP or IntelliCAD MEP Cost Consultants?

16 Impact of BIM on Project Management role Level 3 (Integrated collaborative models) 1. ibim Cloud based + mobile access e.g. Asite? (subscription provides access to all design software required) AutoDesk 360? 2. Legal / Liability issues could get blurred! 3. Document Management:- Monitoring of design development / release of versions of integrated model (e.g. Autodesk Vault). 4. Access control to the model / data fields of the model for design input + electronic tendering. N.B. BIM Overlay to the RIBA Plan of Works is a useful reference.

17 Impact of BIM on the Traditional QS role

18 Impact of BIM on Traditional QS role The Bill of Quantities Much derided and misunderstood BoQ = allows all builders to base their bid on the same quantities / specification / scope (i.e. level playing field). 1. Very efficient for GC estimators. 2. Clients undervalue it s use for post contract cost control.

19 Impact of BIM on Traditional QS role The Bill of Quantities The BIM model = sophisticated data base that just happens to generate pretty pictures. Different Fields contain various types of data for each component (including geometry / areas, specification, supplier etc. customisable) 1. Separate fields can be created within each object for each bidding contractor / works contractor to submit their rate. 2. Access control to parts of BIM model!! The BIM Model can therefore be effectively a new form of BoQ (if fully developed).

20 Impact of BIM on Traditional QS role Quantity Take off Can Quantities be generated at the Touch of a Button? Maybe! depends on how clearly the Design Team have been directed on how the model should be configured / data entered into what fields (e.g. Model Progression Specification/ COBie?) It is possible but: Modellers must be consistent and accurate Quantities generated haven t been properly compared to SMM / NRM! How does a QS access the data?

21 Impact of BIM on Traditional QS role Dick Barker, Director, Laing O'Rourke, Head of Model Based Measurement and Costing (February 2011). Considering BIM from a measurement and costing perspective there are three important cornerstones of the process: 1. 3D modelling to generate the geometry of what has been or might be designed 2. Defining the scope of work in Bills of Quantities and dynamically populating the Bills with quantities from the model 3. Specification, auto-annotating the 3D and 2D drawings from the model as well as dynamically linking the Bill descriptions to the specification.

22 Impact of BIM on Traditional QS role How does a PQS access the data? Data Export in universal format by designer? Copy of Revit to edit the cost data fields? Other bespoke Software e.g. 1. VICO Office? Take off module to create elements / subelements / items linked to model objects updates quantities as the model evolves. 5D Estimating linked to model allows iterative up -dates with model evolution. 2. Autodesk Quantity Take off? 3. Causeway / MasterBill CAD / BIM Measure? On-screen take off, links to CATO Bill production software / libraries.

23 Hurdles to BIM adoption

24 Hurdles to BIM adoption BCIS 2011 BIM Adoption Survey / Government s BIM Strategy paper The effective adoption of BIM technologies by cost consultants and planners has been slow to date with a general lack of awareness. The profession needs to engage in the process, along with the positive desire of the industry for training and the establishment of standards. There is a requirement for the industry to.. educate the mass market to the significant time and cost benefits that can be achieved through the successful implementation of BIM, which can only be achieved by the industry working cohesively to set criteria and standards.

25 Hurdles to BIM adoption Practical Considerations Costs 1. Software 2. Hardware 3. Training 4. Loss of Productivity at inception Processes People
