1. CVE 1000 Construction Engineering The Project Delivery System Prof. Ralph V. Locurcio, PE

2. Why we are “civil” engineers…  The definition of “civil” of or relating to citizens as individuals; a condition of social order; adherence to social systems and consideration for others

3. Why we are “civil” engineers…  The definition of engineers Engineering is the application of science to the needs of humanity. This is accomplished through knowledge, mathematics, and practical experience applied to the design of useful objects or processes.

4. Why we are “civil” engineers!!  We build “civility” into daily life Water & Sanitary systems - keep us healthy Housing – keeps us warm & safe Transportation systems – help us travel Factories – build the stuff we need & want Office buildings – give us a place to work Schools – a place to prepare our children Energy systems – keep it all running

5. Recent memorable examples  Reconstruction of the World Trade Center  Reconstruction of New Orleans after hurricane Katrina

6. Class Problem…  The time is 2000BC in Egypt  The pharaoh has appointed you PM to construct his burial pyramid  He wants to know…  What tasks are necessary?  What is the sequencing of tasks?  How long will it take?  How many people will you need?  What will it cost?

18. Participants & Responsibilities…  The Owner  The Designer  The Builder  The Project Manager (PM)  The Construction Manager (CM) Class exercise: define responsibilities

19. The Owner…  Pays for the project  Accepts the project on completion  Sets criteria for design  Sets cost parameters  Establishes time line for completion  Determines contract type  Hires the designer & builder  Appoints the construction manager  Makes decisions when needed

20. The Designer…  Oversees planning & advises owner  Evaluates siting options  Develops concept design  Prepares contract plans  Prepares contract specifications  Prepares cost estimates  Prepares bid package  Assists in selection of builder  Assists during construction

21. The Builder or Contractor…  Prepares and submits bid documents  Organizes project team  Hires & pays subcontractors  Obtains permits and licenses  Mobilizes contract work force on NTP  Builds IAW plans & specifications  Controls quality & cost  Manages construction site & safety  Turns over completed project on time

22. The Project Manager (PM)  Represents the Owner in all matters  Serves as technical assistant to owner  Controls project budget, schedule, quality & timing  Makes recommendations on budget, schedule, changes, & quality changes  Makes recommendations on payments  Recommends acceptance of project

23. Construction Manager (CM)…  Represents the contractor in all matters  Oversees construction operations  Monitors schedule & costs  Provides interface with client operations  Follows all contract provisions  Makes recommendations on changes or claims  Submits progress payments  Responsible for quality control  Ensures all work is completed

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

25. Bar Chart Schedule…

26. Velocity Chart…or S-curve

27. Line-of-Balance Chart

28. 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

30. CPM/PERT Chart…

31. Management of Quality…  Definition of Quality Control  Definition of Quality Assurance  Designer’s responsibility  Contractor’s responsibility

32. Total Quality Management

33. Savings from quality

34. Quality Control Process…  Must have a Quality Control Plan… an inspection" system”  Special considerations:  Timing of inspections; preclude delays  Protection of work in place  Most work is irreversible; i.e.. concrete, foundations  Logistical sequencing  Follow plans & specifications; changes not authorized  Report and correct errors & deviations from spec; documents  Three phased inspections system  Preparatory inspection  Pre-inspection  Final inspection  QC Staff must be qualified, trained & dedicated

35. Inspection & Testing Manual…  Detailed inspection procedures:  Preparatory inspection: work flow, submittals, methods  Initial inspection: workmanship & components  Follow-up: results of work, tests, appearance  Acceptance/rejection criteria  Testing requirements & frequency  Responsibilities for testing  Approval of outside labs & testing agencies  Timing of inspections & work  Reports required, frequency & format  Documentation of test results
