Career Fair-homework  Attend the Annual Career Fair that will be held in Clemente on Sep 30 from 1100am to 300pm.  Interview at least 3 of the employers who hire civil engineers  Turn in a summary sheet of the information you obtained – due October 6 th  Follow up with a resume & cover letter to a prospective firm you might like to work for

Career Fair-interviews  Name each of the companies that you interview and include the following: What type of services do they provide? Who are the principal clients or customers? Do they employ civil engineers? What types of jobs are they hiring for? Do they use project management? How are their project managers trained? What are typical responsibilities for entry level engineers? Do they have a development program for young engineers? How are personnel evaluated? Is a PE license required? What benefits are provided: health, 401k, dental, vacation? Does the employer participate in paying for these benefits? Would you like to work for this company?

Construction Scheduling…  Common methods: 1.Bar Charts 2.Velocity Charts 3.Line-of-Balance Charts 4.Network Diagrams: CPM/PERT

Characteristics of methods…  Bar Charts  Simple & easy to read  Based on contractor field experience  Do not show interdependencies  Do not show critical path  S-Curves  Good for showing progress  Do not show interdependencies  Do not show critical path  Line-of-Balance  Show interdependencies  May show progress  Do not show critical path

CPM in Construction…  MS Project is CPM & multi-format Excellent for small projects; easy to use Widely used & relatively inexpensive Several other products on market  Primavera used for large projects More flexible Includes resource & budget Includes database for tracking submittals Requires more capable computers Generally requires trained operator

CPM in Construction…  Tasks are not all consecutive  Need to show interdependencies  Need to identify critical tasks & timing  Need to show slack or float  Need to see tasks superimposed  Need to chart progress & payment

5 Step Scheduling Process… 1.Identify key work elements 2.Estimate time durations for each 3.Establish logical order of tasks 4.Determine precedence/dependency 5.Display in graphical/network format

Activity = Basic work unit  Any single, identifiable & measurable work step in the total project.  A “time consuming” task  Two conventions:  Activity on Arrow… AOA networks  Precedence diagrams

Network relationships…  Finish-to-start: The activity may not begin until the preceding activity is completed Most common or conventional relationship  Start-to-start: The activity may begin any time after the start of a preceding activity Very common and useful, often includes a lag time Finish-to-start Activity A Activity B Finish-to-start w/lag Start-to-start Start-to-start w/lag

Network relationships…  Finish-to-finish: The activity must finish at the same time as a preceding activity Infrequently used  Start-to-finish: The activity may not finish until the predecessor starts Finish-to-finishFinish-to-finish w/lag Start-to-finish Start-to-finish w/lag

Actual WBS Template – Des or Proj 1&2

Project Flow Chart 1.Identify activities = individual tasks 2.Arrange activities in logical order 3.Add a time line – from start to project completion 4.Array the tasks in “time order” sequence 5.Show “precedence”… what activity must be completed before another can begin 6. Draw lines to connect activities to show flow of work 7. Time sequencing is “relative”… not exact 8. Flow chart is used to explain project tasks to team
