3.35 m
It is advisable for a site plan to contain a large scale map of the overall area and to indicate where the project is located on the site.
Vicinity Map
This drawing has elevation as its vertical axis and horizontal distance as measured along the centerline of the facility as its horizontal axis.
Profile
This applies to curved facilities, such as highways or railways only. It consists of a graph with a roadway or railway cross slope versus horizontal distance.
Super Elevation Diagram

Unsafe Condition
Rule is the guidelines regarding Personal Protective Equipment (PPE).
Rule 1080
How do you test the relative consistency of concrete?
Slump Test
Most important process to prepare concrete:
Batching
The number of days final curing for a concrete cement pavement is done for:
14 days
________ is the process of increasing the density of a soil by mechanically forcing the soil particles closer together, thereby expelling air from the void spaces in the soil?
Compaction
________ is an increase in soil density of a cohesive soil resulting from the expulsion of water from the soil’s void spaces.
Consolidation
Compactor production is based on the following data: I. Number of paces required II. Width compacted per pass III. Compactor speed IV. Compacted lift thickness V. Job Efficiency
all of the above
The process of giving natural soils enough abrasive resistance and shear strength to accommodate traffic or design loads is called?
Ground Modification
It involves dropping a heavy weight from a crane onto the ground surface to achieve soil densification.
Dynamic Compaction
________ or placing additional weight on the soil surface, has long been used to densify cohesive soil.
Surcharging
________ is the process of densifying cohesionless soils by inserting a vibratory probe into the soil.
Vibroflotation
Workers in an excavation are protected from caveins by one of the following methods: I. Sloping or benching of the sides of the excavation. II. Supporting the sides of the excavation by shoring. III. Placing a shield between workers and the sides of the excavation. IV. Drying soil to prevent collapsing.
I, II, and III
In highway construction, the process of cutting down high spots and filling in low spots of each roadway layer is called?
Balancing
It is nothing more than a column driven into the soil to support a structure by transferring building loads to a deeper and stronger layer of soil or rock.
Pile
It is the process where a load is prepared for lifting using a lifting machine. The main part of this process is the tying up of the load with sling and other connecting devices so that the load could be hooked onto a crane.
Rigging
Complete or partial dismantling of a building or structure by preplanned and controlled methods or procedures.
Demolition
It is capable of spreading, consolidating, and finishing a concrete slab without the use of conventional forms.
slipform paver
It is a very versatile machine that has the longest reach for digging and dumping of any member of the crane shovel family.
dragline
The bucket volume contained within the bucket when following the outline of the bucket sides is called:
Plate line capacity
Assumes a level of material flush with the lowest edge of the bucket.
Water line capacity
The bucket capacity when the load is struck off flush with the bucket sides.
Struck capacity
It represents those components of cycle time other than travel time.
Fixed time
This represents the travel time required for a unit to haul material to the unloading site and return
Variable time
This should be done during the first seven days in order that the expected development of strength will be obtained and the occurrence of plastic cracks will be prevented or minimized.
Curing
A mixture of cementitious materials and water, with or without aggregate, proportioned to produce a creamy consistency.

Joints placed in concrete pavements, which are usually placed transversely, at regular intervals, to provide adequate expansion space for the slab to expand when the pavement is subjected to an increase in temperature.
Expansion Joint
Joints placed in concrete pavements, which are usually placed transversely at regular intervals across the width of the pavement to release some of the tensile stresses that are due to a decrease in temperature.
Contraction Joint
Joints placed in concrete pavements, which are usually placed transversely across the pavement width to provide suitable transition between concrete placed at different times or on different days.
