Study Notes

Building Codes and Regulations

Building codes regulate the design and construction of new buildings to ensure health and safety.
Fire Code governs activities in existing buildings, particularly related to fire protection.
Zoning regulations determine the location of hazardous occupancies and land use.
The Americans with Disabilities Act (ADA) mandates areas of refuge in multistory buildings for disabled persons during emergencies.

Roles and Responsibilities

Structural engineers design the building's structural frame to endure various loads.
General contractors oversee the construction process, ensuring timely and budget-compliant project completion.
An architect scale is utilized to create accurate, scaled drawings for building construction.

Building Plans and Specifications

Floor layout sections detail the arrangement of walls, doors, and corridors.
Building specifications outline the specific materials and equipment required for construction.

Importance of Firefighter Involvement

Firefighters review building plans for fire prevention and preplanning, enhancing safety measures.

Construction Technology

Computer-Aided Design (CAD) produces electronic building plans for streamlined access and sharing.

Construction Site Preparation

Site preparation ensures that the ground is ready to support the building structure.
Soil testing evaluates soil quality and load-bearing capacity to avoid structural issues.
Piles serve as deep foundations, transferring loads to stable soil or bedrock.
Shallow foundations distribute loads broadly and prevent structural failure.

Excavation Processes

Excavation involves digging the site to the necessary depth for foundations.
Dewatering is essential to avoid water accumulation in excavated areas.
Shoring and sheeting offer support to excavation sides, preventing soil collapse.

Foundation Types

Concrete slab foundations provide flat bases for buildings.
Fieldstone foundations utilize large stones, laid without mortar, for unique construction.
Wood post foundations present a fire hazard due to the material's combustibility.

Construction Safety Measures

OSHA enforces regulations focusing on fall protection and reducing accident risks from moving/ collapsing materials.
Cranes facilitate the movement of heavy materials on construction sites, posing potential hazards such as vulnerability to collapse under fire or severe weather.

Construction Methods

Modular construction allows for quicker assembly through prefabricated components, enhancing efficiency but potentially introducing flammable materials.
Intermodal steel building units (ISBUs) use repurposed shipping containers for sustainable building practices.

Fire Hazards in Construction

Renovation projects may involve incomplete fire protection systems, posing significant risks.
Demolition work faces dangers of structural instability and potential collapse.
Scaffolding is used temporarily for support, but can pose risks during fires as they may collapse.

Material Properties and Concerns

Wood’s strength is affected by moisture content and grain direction, and is inherently flammable.
In fire conditions, steel can elongate, risking structural failure.
Reinforced concrete combines the strengths of concrete and steel, making it a preferred material for construction.
Deflection describes material bending under stress, crucial for understanding load-bearing capacities and structural design.
