What is the purpose of the inspection department according to SECTION 107?
- Perform inspections
- Ensure compliance with building codes
Inspections are crucial for maintaining safety and standards in construction.
List the types of inspections performed by the inspection department.
- Footing inspection
- Under-slab inspection
- Foundation inspection
- Rough-in inspection
- Building framing
- Insulation inspection
- Fire protection inspection
- Final inspection
Each inspection type serves a specific purpose in the construction process.
When should a footing inspection be made?
After trenches are excavated, grade stakes installed, reinforcing steel in place, and before concrete is placed
This inspection ensures that the foundational elements are correctly prepared.
What is the timing for an under-slab inspection?
After all materials and equipment to be concealed by the concrete slab are completed
This inspection checks that everything is in place before the slab is poured.
Foundation and crawl space inspections occur after what condition is met?
All foundation supports are installed
This ensures that the foundational structure is secure before proceeding.
What does a rough-in inspection check for?
All building framing and parts of electrical, plumbing, fire protection, or HVAC systems that will be hidden
This inspection is crucial before any wall or ceiling finishes are applied.
What is the purpose of a framing inspection?
To ensure that roof, wall, ceiling, and floor framing is complete with appropriate blocking, bracing, and firestopping in place
Framing inspections must occur after the roof (excluding permanent roof covering) is complete.
List the items that must be in place and visible for framing inspection.
- Pipes
- Chimneys and vents
- Flashing for roofs and chimneys
- Insulation baffles
- Lintels required to be bolted to the framing
Lintels must not be covered by any finish material before approval.
When should insulation inspections be made?
After an approved building framing and rough-in inspection and after the permanent roof covering is installed
Insulation and vapor retarders must be in place before any wall or ceiling covering is applied.
What is required before fire protection materials can be concealed?
They must be inspected and approved by the code enforcement official
Fire protection inspections are necessary in all buildings where materials are used for fire protection purposes.
What is the purpose of a final inspection?
To ensure completion of the work authorized under the technical codes for each trade
Final inspections are made after all work is completed.
What is a hub in excavation and grading?
A small stake driven into the ground to identify a reference point
Hubs are essential for site preparation and alignment.
What does 8’ indicate on a hub?
The hub is offset 8 feet from centerline
This measurement helps in determining the position of the hub relative to the pipeline.
What does Sta represent in excavation?
Distance from starting point in 100 ft
For example, 1 + 50 = 150’.
What does the letter C signify in excavation documentation?
Cut
This indicates the flow line of pipe below the top of the hub.
What is the purpose of driving a nail into the top of a hub?
To provide an accurate reference
This ensures precise measurements for excavation.
What is the function of a reference or information stake?
To identify the hub’s elevation and situation in relation to the pipeline
It shows the horizontal measurement from the hub to the centerline of the cut or fill.
The distance shown on the reference stake is also called the Offset. True or False?
TRUE
The offset is crucial for accurate excavation and grading.
What is the formula to calculate slope as a percent?
Slope = Rise ÷ Run
Vertical rise is expressed in units of rise or fall, compared to a horizontal distance of 100 units.
A 45º angle corresponds to what percentage of slope?
100%
A 45º angle indicates that the vertical rise/fall is equal to the horizontal distance.
What type of rock is formed from molten magma and is the hardest to excavate?
Igneous rock
Igneous rock is formed from molten magma.
Which type of rock is the easiest to excavate and is formed from sediments?
Sedimentary rock
Sedimentary rock is formed from sediments that were compressed by water and overlying layers.
What is the water table?
The level of underground water
The water table varies in depth from season to season.
What system can be used to lower the groundwater table in bad groundwater conditions?
Wellpoint system
This system helps manage groundwater levels.
