  1. Dam Construction AlternativesSite Specific Matrix Jason Butler 3/4/2011

  2. Worcester Polytechnic InstituteCivil & Environmental Engineering • Major Qualifying Project (MQP) • Stantec Project Center • Project Advisors: • Professor Frederick Hart • Professor Suzanne Lepage • Stantec Consulting Service Inc. mentors • Daniel Gilbert • Greg Yankey • Brad Smiley

  3. Project Scope • Develop an understanding of dam construction alternatives: • Concrete-Filled Cellular Sheet Pile Cells • Float-In • Roller Compacted Concrete • Develop a user friendly site specific matrix for selection of appropriate dam construction alternative

  4. Project Deliverables • Overview of three dam construction alternatives • Capstone Design Project • Design a site specific dam construction matrix • Calibrate matrix at previous dams built • Apply matrix to future dam projects

  5. Concrete-Filled Cellular Sheet Pile Cell Construction • In-the-wet construction • Permanent cofferdam structure • Tremie concrete pour • Cost and schedule saver • Accommodates to irregular rocklines • Suitable for volatile rivers

  6. Float-In Construction • In-the-wet construction • Prefabrication of dam segments created at offsite location • Casting basin or launch facility • Large construction equipment • Extensive underwater diver work

  7. Roller Compacted Concrete Construction • In-the-dry construction • Temporary cofferdams • Dewatering required • Rapid placed concrete • Construction completed in stages • Optimize dams geometry

  8. Matrix

  9. Calibration of Matrix • Kentucky River Lock and Dam No. 9 (Cell) • Braddock Dam (Float-In) • McAlpine Dam (RCC)

  10. Application to Future Projects • Kentucky River Lock and Dam No. 8 • Currently under design process approval • Matrix Results: • Concrete-Filled Cellular Sheet Pile Cells

  11. Application of Matrix • Gain basic knowledge about dam construction • Useful for clients to choose appropriate dam construction technique to use at specific location • Entry-level engineers can use as a reference to get on board with the project quicker • Serves as useful information on dam construction topics to allow clients and engineers to be on the same page
