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
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 1994 - present
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

Industrial Development Needs for Quantity Surveyors: The Post
Recession Dynamics”? (2011)
11. Changing Role of PQS
Main Growth areas

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.
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 / 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.
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.”
