Total questions: 30
Worksheet time: 15mins
What is the purpose of an estimate in a construction project?
To determine the exact profit of the project
To calculate the approximate cost of the project
To finalize the contractor’s payment
To supervise construction activities
Which estimate is prepared to accommodate changes in the project scope?
Supplementary Estimate
Sub Estimate
Revised Estimate
Complete Estimate
What type of estimate is used to calculate costs for maintenance of structures?
Repair Estimate
Annual Maintenance Estimate
Sub Estimate
Supplementary Estimate
Which estimate is prepared when additional work is required during progress of work?
Main Estimate
Supplementary Estimate
Revised Estimate
Detailed Estimate
Which method of approximate estimation uses the total built-up area of a building?
Plinth Area Method
Cubical Content Method
Service Unit Method
Typical Bay Method
The Cubical Content Method considers:
Area of the plinth only
Volume of the structure
Length of walls
Service units in the building
In which method of approximate estimation are repetitive structural units like bays used?
Typical Bay Method
Service Unit Method
Plinth Area Method
Cubical Content Method
The Service Unit Method is best suited for which type of project?
Residential buildings
Industrial buildings
Hospitals or schools
Highways
Which estimate provides item-wise expenditure?
Preliminary estimate
Detailed estimate
Plinth area estimate
Rough cost estimate
The Cubical Content Method is more accurate than the Plinth Area Method because:
It considers the total volume of the structure
It excludes the cost of roofing
It uses service units
It ignores height variation
What is the standard unit of measurement for brickwork?
Cubic meter ( m3 )
Square meter ( m2 )
Kilogram (kg)
Number of bricks
For plastering work, deductions are made for openings only if their size exceeds:
0.1 m2
0.5 m2
1.0 m2
No deduction is made
The degree of accuracy in measurement for masonry work is:
Nearest 1 mm
Nearest 1 cm
Nearest 1 m²
Nearest 0.01 m³
Which thumb rule is used to estimate the number of bricks required for 1 m³ of brick masonry?
350 bricks
500 bricks
1000 bricks
1200 bricks
The outturn of work refers to:
Cost of materials per day
Quantity of work done by a worker in a day
Estimated profit
Total material required
Aggregates are primarily required for:
Brick masonry
Concrete work
Plastering
Painting
The Schedule of Rates (SOR) is used for:
Calculating quantities
Estimating cost of works and materials
Preparing lead statements
Lump sum provisions
The Standard Data Book is mainly used to:
Track project profits
Provide standard labor and material data
Prepare drawings
Fix tender value
Lump sum provision in an estimate is made for:
Detailed items
Unspecified or miscellaneous works
Cement and sand
Transport only
Observed data refers to:
Historical cost records
Data collected at site during execution
Schedule of rates
Lump sum data
Specification is essential in construction because it:
Defines quality, materials, and workmanship requirements
Adds decorative details without cost impact
Replaces drawings in all cases
Eliminates need for supervision
The main types of specifications are
Written and verbal
Standard and non-standard
General and detailed
Itemized and lump sum
The purpose of general specifications is to
Give detailed quantities
Provide brief overview of materials and workmanship
Fix project cost
List all construction items
Detailed specifications are necessary for
Feasibility studies
Quality overview
Preparing tenders and execution
Cost comparison
Specifications for cement include
Chemical composition only
Type, grade, and storage conditions
Mixing ratio only
Application method
The primary requirement for sand used in construction is:
Cheap availability
Freedom from organic impurities and silt
Grain color
Transportation cost
Most important property of reinforcement steel is:
Weight per meter
Flexibility
Tensile strength and grade
Length
Water used for construction should conform to:
Neutral pH only
Potable water standards
Hard water standards
Rainwater standards
A construction report is:
List of costs
Written document describing progress or findings
Contract agreement
Work schedule
Which is NOT a key consideration while writing a report?
Clarity and conciseness
Accurate data and evidence
Logical organization with headings
Inclusion of personal bias and unsupported opinions
