Detailed Quantity Survey Flashcards
A profession within the construction industry in which skilled professionals contribute by calculating the quantities required for a project.
Quantity Surveying
A _________ and _________ are essential documents prepared by a Quantity Surveyor to outline the materials, labor, and cost associated with concrete works in a construction project.
Bill of Quantities (BOQ)
SCHEDULES OF QUANTITIES
The process of calculating the quantity and cost of materials, labor, and equipment required for construction projects.
Estimation
A critical structural element that transfers loads from the building to the ground.
Foundation
A type of foundation that transfer the building load to the ground
Footing
A type of foundation that is used for weak soils to distribute load over a larger area.
Raft Foundation
A type of foundation that is used for deep foundations in weak soil conditions.
Pile Foundation
Are vertical structural members that supports loads.
Columns
Horizontal structural members transferring loads
Beams
Refers to the standardized proportion of cement, sand, and gravel used in concrete mixtures to achieve specific strength and durability requirements.
Concrete mix class
A class of concrete that has a strength of 4,000 psi or 28 MPa that is commonly used for bridges, high rise buildings, and prestressed concrete.
Class AA
A class of concrete that has a strength of 3,500 psi or 24 MPa that is used in beams, columns, slabs, footings, or structural elements.
Class A
A class of concrete that has a strength of 2,500 psi or 17 MPa that is used for footpaths, small structures, and non load bearing elements.
Class B
A class of concrete that has a strength of 2,000 psi or 14 MPa that is used for concrete filling, base layers, and leveling before main concrete.
Class C
A detailed document used in the construction industry that itemizes and quantifies the materials, labor, and other resources required for a construction project.

_______________ for concrete works provides a detailed guideline on the materials workmanship construction methods and quality control measures required for concrete structures.
Specification writing
All concrete work shall comply with_________ and __________ for structural integrity and durability.
ACI 318 and ACI 301
General purpose cement for standard construction
Type I
Moderate sulfate resistant cement for structures exposed to mild sulfate conditions
Type II
High early strength cement for rapid construction needs
Type III
Low heat cement for massive concrete structures
Type IV
High sulfate resistant cement for severe sulfate exposure
Type V
Figuring out how much all the stuff you need will likely cost
Cost estimation
Deciding how much money you’re willing to spend on building that project
Budgeting
A type of costing methods that involves breaking down the cost of a concrete item or activity into its individual components such as materials, labor, equipment, and overhead
Rate Analysis
A type of costing method that calculates the total cost by multiplying the quantity of concrete items by their respective unit cost
Unit cost estimation
Includes wages, salaries, benefits, and payroll taxes paid to employees directly involved in production or supporting production
Labor cost
Represents the cost of acquiring, maintaining, and operating machinery, tools, and other equipment needed for production, including depreciation, repairs, and energy consumption
Equipment cost
The changes in material prices, supply and demand dynamics, and currency exchange rates
Market fluctuations
Involves setting aside funds to cover and foreseen expenses or risk that may arise during the construction project
Contingency cost
