Study Notes

Sustainability Concepts

Sustainability: Development that satisfies current needs without jeopardizing future generations' abilities to meet theirs.
Green Building: Integrates sustainable design in both construction and operational processes.

Environmental Labels

Environmental Labels: Standards that detail requirements for sustainable materials and products.
Type I Ecolabel: Third-party, independent certifications ensuring unbiased environmental performance data.
Type II Self-Declared Environmental Claim: Claims made by manufacturers without independent verification; less reliable than Type I.
Type III Environmental Impact Label: Offers a detailed assessment of environmental impacts through the product lifecycle without providing ratings.

Lifecycle Assessments

Global Warming Potential: Quantifies a product’s lifecycle contribution to global warming via greenhouse gas emissions.
Life Cycle Analysis (LCA): Comprehensive evaluation of a material's environmental impacts, from resource extraction to disposal.
Embodied Energy: Total energy consumption attributed to a material throughout its lifecycle.
Cradle-To-Gate Analysis: LCA that analyzes only the phases until the product leaves the manufacturer's premises.
Embodied Water: Total freshwater used throughout a material's lifecycle.
Embodied Carbon: Total carbon emissions produced over a material's lifecycle.

Sustainability Standards

LEED (Leadership in Energy and Environmental Design): A widely recognized rating system for building sustainability.
LEED Prerequisites and Credits: Mandatory and optional points contributing to the LEED rating, respectively.
Living Building Challenge: A high standard aiming for eco-positive structures that enhance the environment.

Construction Documentation

Drawings: Visual representations detailing construction methods and materials.
Specifications: Written descriptions of construction processes.
Construction Documents: Combined drawings and specifications directing building construction.

Legal and Regulatory Concepts

Zoning Ordinance: Local laws dictating land use, including building height and lot coverage.
Building Code: Minimum standards for health, safety, structural integrity, and fire safety in construction.
Model Building Code: Templates that local authorities can adopt instead of creating custom codes.

Regulatory Bodies and Standards

National Building Code of Canada: Standards set by the Canadian Commission on Building and Fire Codes.
International Building Code (IBC): Foundational code for most U.S. building regulations.
Occupancy Definitions: Categorization of building activities relating to life safety.
ASTM International: Organization that establishes testing and material standards.
Canadian Standards Association (CSA): Equivalent of ASTM for Canada.
ISO (International Organization for Standardization): Sets global standards.
ANSI (American National Standards Institute): Develops North American standards for various products.
NIST and NRC-IRC: Government entities for research and standards in construction.

Project Delivery Methods and Management

Design/Bid/Build: Distinct design and construction phases managed by separate entities.
General Contractor: Oversees the entire construction project.
Subcontractor: Specialized contractors working under a general contractor.
Design/Build: Single entity handles both design and construction, often used for faster completion.
Turnkey: Contractor provides design, construction, and financing.
Phased Construction: Overlaps design and construction to expedite project completion.

Financial and Contractual Aspects

Performance Bond: A guarantee of project completion.
Payment Bond: Assures subcontractor and supplier payments.
Fixed-Fee Compensation: A pre-set payment regardless of actual costs.
Cost Plus Fee Compensation: Owner pays actual costs plus a fee, with risk associated.
Guaranteed Maximum Price (GMAX): Caps owner’s costs while contractor absorbs any excess.
Incentive Provisions: Aligns contractor benefits with project savings.

Scheduling and Optimization

Sequential Construction: Each construction phase completes before the next begins.
Critical Path: Sequence of activities dictating the project’s minimum completion time.
Float: Activities that can be delayed without impacting the overall schedule.
Critical Path Method: Technique to optimize project duration and cost.

Innovative Construction Practices

Integrated Project Delivery (IPD): Shared responsibilities and risks among key project stakeholders.
Lean Construction: Focuses on reducing waste and increasing efficiency across all project aspects.
Building Information Modeling (BIM): 3D digital modeling for enhanced visualization of building systems.
Computer-Aided Design (CAD): 2D representations aiding in architectural design processes.
