- Abstract:
Existing information systems used by contractors and subcontractors are found in surveys to be flawed in modelling the requirements for control of production time and cost. Structured systems development is carried out to devise models based on data flow diagrams that represent the practice of project planning, monitoring and control. A case study on information systems used by a design and build organisation is included. Prototyping is recommended to further the development of information systems. Criteria are developed for concept models of building project information. Design and build procurement methods that allow the contractor to prepare data are considered, where information can be coordinated. Data coding and phraseology are developed in relation to activity-based schedules and a work breakdown structure. The use of a coding system is illustrated by a case study and criteria for coding system and work breakdown requirements given. Master Lists for activity coding are tested on site managers. The monitoring and integration of both planning and job cost accounting is shown in a case study and criteria given for control in relation to integration. Main contractor requirements are considered, in relation to accounting, valuation and cost value reconciliation. A project case study compares valuations based on programme progress with those of the surveyor. The use of computer systems is reviewed for project and production control. Directly employed resource and subcontract requirements for integration are analysed and a case study develops site based weekly time and cost control. Proposed systems are designed for main and subcontractor control and illustrated by data flow diagrams. The contributions made to the knowledge of the subject are: (i) An activity coding system that combines and rationalises existing systems. (ii) A set of criteria for the analysis of coding systems and for project control models that are unique. (iii) Models developed for main contractor control and for subcontracted or directly employed resource control, based on activity descriptions which are in advance of existing systems.
