ORBEE Learning Material Introduction to Integrated Design and Delivery Systems Lesson 4- BIM & Construction Project Management

Lesson Plan Co-ordination problems in construction projects Using BIM for 4D Simulation Traditional scheduling methods and the need for 4D Simulation Using BIM for Quantity Take-Off and Construction Estimation

Key Learning Outcomes To understand the need for construction production simulation To analyse key benefits of production simulation To comprehend various types of 4D applications

Construction Co-ordination Problems AreaCo-ordination Problems Design No direct cost feedback on design decisions Coordination of trades Sub-Contractor Cost Missing / Incorrect Design Information Inability to reuse data for shop drawings Field rework required for prefabricated components Padding to compensate for risks Poor subcontractor work flow – “Starts and Stops” Inadequate quantity information for planning Lack of owner trust – difficulties in communicating cost and schedule issues Production control is based on subjective information Frequent starts and stops Estimating is time-consuming and occasionally inaccurate Construction Insufficient as-built project documentation Renovation, addition and demolition planning is time-consuming Facility Management Insufficient as-built project documentation Renovation, addition and demolition planning is time-consuming

Using BIM for 4D Production Simulation Created by linking 3D BIM with Project Timeline Used to display both temporary and permanent components Referred to as product- process models

KEY ADVANTAGES OF PRODUCTION SIMULATION

Integration of Production and Process Model

Using 4D for Macro and Micro Level Communication Using 4D at a Macro Level – Site Logistics – Staging Areas – Access routes and disruptions Using 4D at a Micro Level – Defining Construction Sequence – Identification of space-time conflicts

CPM Scheduling A work breakdown structure, showing a complete list of all activities required to complete a project; Time duration for each project activity; Dependency between project activities; and The time (duration) that each activity will take to completion.

Line of Balance (LOB) Uses Location as basis for Scheduling Ideally suited for activities involving repeated block of activities (e.g. high rise construction or road works) X-axis represents the timeline of the project, whereas the Y-axis identifies the work areas that identify a project.
