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 developedFee % from BoQ reducing with client demand + new technologyVarious Surveys 1994 - present


Willis et. al. (1994)



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.

Impact of BIM on Project Management role

Level 2 (various designers models combined)• CONSULTANTS APPOINTMENTS / SCHEDULE OF

SERVICES / FEES1. 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 model5. Schedule Deliverables from model (i.e. plans,

elevation, sections etc.)

Level 2 (various models combined)• CONSULTANTS APPOINTMENTS / SCHEDULE OF

SERVICES / FEES3. Master planning - Increased productivity /

visualisation of design4. Software Interoperability:-

• ArchiCAD or Revit Architecture, • Revit Structures or Tekla Structures, • Revit MEP or IntelliCAD MEP• Cost Consultants?


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.


Impact of BIM on the

Traditional QS role

The Bill of Quantities

Much derided and misunderstoodBoQ = 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.

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).


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?


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.”


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 / sub-

elements / 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.


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.”
