This instrument uses a magnifying telescope to take precise horizontal readings for leveling.
What is an automatic level?
Before starting a project, official metal rods with plastic washers are used to define this.
What are boundary markers?
This ingredient binds sand and gravel together in concrete.
What is cement?
The bottom part of a foundation that distributes the building load.
What is a footing?
This tool is used to check if a surface is perfectly horizontal or vertical.
What is a carpenter’s level?
This tool is used to measure both horizontal and vertical angles on a construction site.
What is a theodolite?
This method uses the 3-4-5 rule to ensure a layout is perfectly square.
What is the Square Method?
The standard unit for measuring concrete strength, also used in pressure.
What is a megapascal (MPa)?
The minimum recommended curing time for concrete to reach full strength.
What is 28 days?
The most commonly used material for reinforcing concrete structures.
What is rebar (reinforcing steel)?
This high-tech device measures angles and distances using a laser and a prism.
What is a total station?
This is the first line established when laying out a building.
What is the front setback line?
Adding too much of this weakens concrete strength.
What is water?
This is the main reason why footings should be reinforced with rebar.
What is preventing cracks and settling?
This type of stand is used to align formwork in sandy or unstable soil.
What is a four-stake stand?
This simple leveling tool works by using water in a transparent tube.
What is a water level?
The tool used to check verticality by aligning it with gravity.
What is a plumb bob?
This chemical reaction makes concrete harden and gain strength.
What is hydration?
The most important factor to consider when designing foundation formwork.
What is lateral pressure from concrete?
This method of marking alignment uses saw cuts in wood to ensure precision.
What is the reference board method?
This tool enhances accuracy in surveying by triangulating satellite data.
What is a GPS localization system?
Before constructing formwork, this must be verified using a 30m measuring tape and checking diagonals.
What is terrain conformity?
This special additive creates tiny air bubbles in concrete to improve durability in freezing weather.
What is an air-entraining agent?
The process of compacting wet concrete using a vibrating tool to eliminate air pockets.
What is consolidation?
This measuring technique ensures concrete formwork is positioned at a perfect right angle.
What is the theodolite method?
