1. 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:Lowest 5:Highes t Cast in Place Concrete Precast Concrete Structural Steel Insulated Concrete Form Concrete Masonry Unit CriteriaRange Weight Factor Cost1-52426810 Schedule1-52481062 Environmental Impact1-5123541 Durability and Lifespan1-5133544 Required Maintenance1-5144354 Availability of Labor1-5154545 Availability of Materials1-5155555 Total Score 2729393631 Ranking 1: Best 5: Worst 54123 Final Construction Method Rankings Construction MethodConstruction DurationEstimated CostOverall Ranking Structural Steel20 Weeks $ 929,674.851 Insulated Concrete Form (ICF)23.5 Weeks $ 898,601.702 Concrete Masonry Unit (CMU)31 Weeks $ 895,957.103 Pre-Cast Concrete22 Weeks $ 1,147,957.104 Cast-in-Place Concrete24.5 Weeks $ 990,457.105 Construction Methods Transition Compound
