Project Management Specialization Construction Productivity Improvement: Human, External and Management Issues Research Team: Dr. Janaka Ruwanpura, Dr. George Jergeas, Eldon Choy, Kasun Hewage,Sushil Peres da Silva, Tanveer Ahmed (Phase II), Markus Liberda (Phase I). Overview • • This research investigates industry practices and develop tools to improve construction productivity of future Alberta construction projects. This will be done by investigating the most critical factors that affect construction productivity and also determining their individual and cumulative impact on project performance. Three specific contributing areas will be considered are human issues, management issues and external issues. The expected deliverables of this research are a root analysis to identify the triggering situations that affect construction productivity, a situation based model to predict construction productivity, a set of practical guidelines, and a pro-active simulation model to plan team dynamics of future projects. Phase IIa: Factors Analysis Management Data collection from 53 participants from Graham, Ellis-Don, PCL, and Ledcor. The participants recognize important factors that affect construction productivity. Rankings (Relative Importance) 2 •Human •Management •External Lack of detailed planning Worker experience and skills Inadequate supervision Worker motivation Non availability of materials Worker attitude and morale Team-spirit of the crew Non availability of information Changes in drawings and specifications Non availability of tools Non availability of equipment Nature of project (size and complexity) Lack of procedures for construction methods Changes in contract Congested work area Worker Motivation 3 4 Member Factors Identified factors are further combined into clusters based on the discussion between the research participants and the research team. These clusters are more logical for the industry to understand reasons for productivity performances. • Changes in Contract • Constructability • Changes in Specifications and Drawings • Worker Motivation • Worker attitude and morale • Team-spirit of the crew • Disrespectful treatment of worker • Inadequate Communication Inadequate Communication •Results based on 22 highly experienced industry experts in Alberta Construction Industry •Average 27 years of construction experience •51 factors are identified in three categories 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 Cluster Name Design and Changes Relative Importance of Factors (only Frequency > 14 are illustrated) Worker Skills 5 Statistics of each Factor Category Rating* Management Human Management Human Management Human Human Management External Management Management Management External External External 37.13 35.30 35.25 26.15 25.60 21.75 20.40 19.20 18.85 18.75 18.60 17.94 16.40 11.95 11.60 Human Phase IIb: Clusters Analysis 1 Phase I: Pilot Study Rank Factor External Non-availability of Information Cluster Composition • Worker experience and skills • Incompetent personnel • Lack of worker training and education • Non-availability of materials • Non-availability of tools • Non-availability of information • Non-availability of equipment Lack of Planning Congested Work Area Lack of procedures for construction methods 8 • Non-availability of materials Inadequate Supervision • Non-availability of tools • Non-availability of information • Non-availability of equipment • Lack of Detailed Planning • 6 7 9 • Congested work area • Site layout • Overcrowded work area • Cleanliness of construction site • Discontinuity in crews makeup • Changes in foremen • Inadequate supervision • Adverse weather conditions Adverse Weather CONTACT Comments on each Factor Dr. JANAKA Y.
