Unformatted text preview: CVEN 349: Civil Engineering Project Management LECTURE # 12 Fall 2009 Dr. Ivan Damnjanovic Role of Project Planning To properly manage project To help determine needed resources To determine costs To determine needed time to complete projects Subcomponents Projects need to be divided in work elements, building blocks or subcomponents. Sub-elements or subcomponents are also referred as work packages packages. Hierarchical representation can be used to describe how individual work packages relate to each other. Such representation is also called work breakdown structure (WBS). 1 Example of Work Breakdown Structure Work Breakdown Structure Requires understanding of the scope of work Determines the status of a project, from the perspectives of: COST QUALLITY TIME What is Planning? In general, it is thinking about the things ahead of time. In context of Construction Management, definition and sequencing of Work Packages PLANNING = WORK BREAKDOWN + WORK SEQUENCING 2 Plans Change! REMEMBER: "Plans are nothing. Planning is everything" ACT NEW INFORMATION Exercise in Groups Come up with one plan and determine the activities you need to do in order to achieve the objective. How to develop WBS? Remember: Work packages are building blocks of WBS Here are some guidelines: Work package m st be clearl must clearly distinguishable Must have unique start and end Should have its own budget Should be defined in such manner that can be measurable 3 Breakdown of Projects Packages can be facilitated by using four common categories: Location or Area Material Type Method of Placement Required Resources Gas Station Example from Halpin's Book Example: Location Work Packages Parking and Service Arena Foundation Building walls Building roof Interior walls/slabs Interior finishes Exterior finishes Electrical systems Mechanical systems 4 Example (cont'd) GAS STATION PARKING FOUND.
