Abstract • We evaluated various construction methods including: Cast in Place Concrete, CMU, ICF, Precast Concrete, and Structural Steel for an Electrical Transition Compound. • Evaluation criteria included cost, construction duration, environmental impact, durability, maintenance, and availability of labor and materials. • A recommendation and an alternative option were submitted to Stantec Consulting Ltd. for the most viable construction options. Objective • Develop evaluation criteria and scoring system, which objectively assesses the five construction methods based upon seven distinct factors. • Select the most viable construction method and an alternative option for the construction of the Transition Compound Evaluation Criteria Methods 1.Research • Review preliminary design documents by Stantec Consulting Ltd. 2.Design Option Selection • Compile list of all potential construction methods based upon the specifications for the Transition Compound 3.List of Tasks • Create a list of all necessary tasks for each construction method 4.Preliminary Construction Schedule • Produce construction schedules using estimated task durations to create a Gantt Chart 5.Preliminary Cost Estimates • Calculate overall costs of construction for each method using various cost estimating tools 6.Design Option Evaluation Criteria • Create evaluation criteria to analyze the possible construction methods 7.Selection of Optimal Design Option Evaluating Construction Methods for an Electrical Transition Compound Andrew Canniff and Christopher O’Connor Location: Dartmouth, Nova Scotia Worcester Polytechnic Institute, Department of Civil and Environmental Engineering Advised by: Fred Hart & Suzanne LePage Results Concrete Masonry Unit (CMU) Construction Duration – 31 Weeks Estimated Cost – $895,957.10 Description – CMU Block Horizontal Bracing Vertical Reinforcing Steel Grouting Scaffolding & Bracing Weatherproofing Insulated Concrete Forms (ICF) Construction Duration – 23 ½ Weeks Estimated Cost – $898,601.70 Description – ICF Blocks Acts as permanent formwork Mix-Designed Concrete Pouring Stages Reinforcing Steel Scaffolding & Bracing Weatherproofing Precast Concrete Construction Duration – 22 Weeks Estimated Cost – $1,147,957.10 Description – Off-site Fabrication Installation of Panels Bracing Weatherproofing Structural Steel Construction Duration – 20 Weeks Estimated Cost – $929,674.85 Description – Off-site Fabrication Installation of Steel Elements Bracing Weatherproofing Cast in Place Concrete Construction Duration – 24 ½ Weeks Estimated Cost – $990,457.10 Description – Formwork Reinforcing Steel Mix-Designed Concrete Pouring Stages Scaffolding & Bracing Weatherproofing Conclusions Recommendation • Structural Steel • Benefits – Faster Construction Time Moderate Cost Accelerates Revenue Production Alternative Option • Insulated Concrete Forms (ICF) • Benefits – Lower Cost Moderate Construction Time Decreased Operation & Maintenance Costs Acknowledgements We would like to thank the following people for their help and support throughout this project: Suzanne Lepage, Fredrick Hart, Jean Peinsznski, Bill Pay, Joshua Pidgeon, Nate Dimock, Brian Hines, and the rest of Stantec Consulting Ltd. 1:Lowe st 5:High est Cast in Place Concrete Precast Concrete Structur al Steel Insulated Concrete Form Concrete Masonry Unit Criteria Range Weigh t Facto r Cost 1-5 2 4 2 6 8 10 Schedule 1-5 2 4 8 10 6 2 Environmental Impact 1-5 1 2 3 5 4 1 Durability and Lifespan 1-5 1 3 3 5 4 4 Required Maintenance 1-5 1 4 4 3 5 4 Availability of Labor 1-5 1 5 4 5 4 5 Availability of Materials 1-5 1 5 5 5 5 5 Total Score 27 29 39 36 31 Ranking 1: Best 5: Worst 5 4 1 2 3 Final Construction Method Rankings Construction Method Construction Duration Estimated Cost Overall Ranking Structural Steel 20 Weeks $ 929,674.85 1 Insulated Concrete Form (ICF) 23.5 Weeks $ 898,601.70 2 Concrete Masonry Unit (CMU) 31 Weeks $ 895,957.10 3 Pre-Cast Concrete 22 Weeks $ 1,147,957.10 4 Cast-in-Place Concrete 24.5 Weeks $ 990,457.10 5 Construction Methods Transition Compound
