Presentation to Balfour Beatty
Salford  University
13/01/2010
+ Background
  Broad  research  areas  within the  work -package: Collaborative 
design and construction
  Visual  management
  Building  information modelling
  Project  management
 Lean construction
 Promise based  management
 Web  services  and  Service  oriented  architecture  (SOA)
  Growing  interest in identifying synergies  between  BIM and lean 
construction principles
+ Concept
 A  production  management system that:
 Uses BIM as the visual platform and lean construction principles as the 
process  enabler 
 Integrates project related information using web services.
 To be used by construction team including  the key  supply  chain 
stakeholders
 End user   interface  is the key
 Various user interfaces to assist in  processes  such as
  Reverse  phase scheduling, Lookahead  planning , weekly planning
 Day-to-day  task  management, including project monitoring and 
control
  Simple  interfaces to make it suitable  for use on a construction 
project
+ Problems with current  situation
 Problems with process and product integration
 Fragmentation is a well  known  problem
 Current systems (ERP, Extranets, Emails, etc) don’t address core 
construction processes
 Construction  projects  are  left  to define /use their own systems 
(mostly  Excel  spreadsheets,  email  and traditional  communication)
 Product Model
 CAD is still  the predominant model
 BIM is fast  taking over but still mostly at the design level
+ Problem with integration
Full  integration with  other  parties (all  functions  and many  different  entities are 
1.3 
integrated  with seamless  real -time integration 
Full integration (all functions integrated with seamless real-time integration) 
12.7 
Partial seamless integration ( several  functions integrated with seamless real-
32.9 
time integration) 
Partial relayed integration (several functions computerized and consolidated in 
32.9 
certain periods (e.g.  daily , weekly and monthly) 
No integration (several standalone computer applications with no integration 
17.7 
No information system ( manual  business processes and  operation

+ What’s  available  currently
 Current products offering construction planning  through  BIM
 Navisworks
 Synchro 4D
  Vico  Constructor
 Tokmo
 The level of integration and planning resolution is extremely 
limited
  There  are many different information sources which need to be 
synchronised in order to  offer  complete project management 
solution
+ Why a new system
 Currently no systems in the  market  that offer such functionality
 Lean production management
 Product and Process model integration
 In practice being successfully exploited by a  select  few, with 
manual  intervention
 Sutter health
 DPR
 BIM  offers  a natural visual and central platform
