Market Issues: Competition, Retail Price, Implementation Time Intended Market Construction companies Rental services  Contractors  Private Construction Entities Competing Systems Standard Tubular Frame Scaffold Mast-Climbing Work Platform Nasif Arefin

Market Issues (cont.): Competition, Retail Price, Implementation Time Retail Price: $ $ Implementation Time Patenting: 2-3 years Manufacture → Testing → Marketing

Economics (Costs): Design/Manufacturing, Operation, Disposal Types of Costs Capital Costs Operating Costs  Fixed  Variable External Costs Service Life-Phases of Design Manufacture Operation Disposal

Social Impacts: Socio-Economic, Communal/Institutional, Individuals/Families Socio-Economic Employment Rates may increase. Manufacture and marketing sales may increase. Highly skilled workers would be required. Communal/Institutional Decrease installation and disassembly leads to decreased noise/disturbance. Decreased injury lawsuits. Saheb Dhody

Social Impacts (cont.): Socio-Economic, Communal/Institutional, People Individuals/Families Fewer injuries from falling objects. Safe relocation of structure due to wheels.

Implementation Requirements: Laws, Codes and Regulations Chemical Products require MSDS sheet. Electrical Products require approval from a field value agency. Worker training is mandatory. Components must be tested by a professional engineer. Building materials imported must meet Canadian Standards and be stamped/stickered. ISO codes must be followed. Signs must be posted indicating potential hazards

Life Cycle: Mitigating Negative Environmental Impacts Raw Material Extracting aluminium from clay reduces deforestation Reusing solar panels reduces energy consumption Manufacturing Using different production technologies reduces pollution and greenhouse gas production Maria Xirui Xie

Life Cycle (cont.): Mitigating Negative Environmental Impacts Transportation Using low-carbon fuel reduces carbon dioxide emission Upstream (Use) Regular maintenance reduces component wear Downstream (Disposal/Reuse) Recycling materials reduces the risk of releasing toxic chemicals and contaminating environment

Conclusion The Dual-Tower Lift Scaffold aims to increase work safety by securing mass while not restricting movement Notable features include:  non-slip aluminium platform  lifelines attached to a roaming grid  meshwork around the platform The design complies with all scaffolding related laws and regulations
