Construction measurement principles

What are Conventions?

• Agreed, consistent standards and rules

• Random guidelines that vary by context

• Personal preferences of individuals

• Unwritten rules that are never followed

Why do we have / need tolerances in construction?

• To ensure that buildings are always perfect and flawless

• Because a building will often be constructed in conditions that are not perfect

• To reduce the cost of construction materials

• To allow for more creative architectural designs

What is Thermal Transmittance?

• It is the measure of the rate at which heat passes through a component or structure

• It is the ability of a material to store heat energy

• It refers to the temperature difference between two surfaces

• It is the measure of how well a material insulates against heat

Name the 5 Steps of a Construction Project

• Plan - Prepare - Design - Construct - Maintain

• Initiate - Execute - Monitor - Close - Review

• Analyze - Develop - Implement - Test - Deliver

• Research - Build - Inspect - Finish - Handover

Construction drawings are produced to a set of conventions - what are they?

• specific units of measurement

• specific views and viewing angles

• specific sheet sizes

• specific color codes

Heat Loss is often connected to the use of insulation to reduce the heat leaving a building. What other important factor do we need to understand about insulation?

• Insulation only reduces heat leaving a building.

• Insulation is used to increase heat entering a building during cold weather.

• Insulation also reduces heat entering a building during hot weather.

• Insulation has no effect on heat transfer.

State the 7 factors that are often used for understanding the Life Cycle Cost Analysis for a Building.

• Land Acquisition - Construction Process - Energy Usage - Water Usage - Operation - Maintenance & Repair - Replacement

• Site Selection - Design - Construction - Operation - Maintenance - Renovation - Demolition

• Initial Cost - Financing - Insurance - Taxes - Depreciation - Resale Value - Maintenance

• Land Acquisition - Construction - Energy Efficiency - Water Conservation - Operation - Upgrades - Disposal

A tolerance is normally expressed as plus or minus (±) a stated amount. Tolerances will vary, depending on the nature of the material. How else can Tolerances be established?

• acceptable variations in the strength of materials

• the color variations of the materials

• the cost of the materials

• the aesthetic design of the materials

What will the result be if the allowable tolerances for a given construction task are not met?

• The work will be completed ahead of schedule.

• The work will not meet the specification.

• The work will be considered acceptable.

• The work will require additional funding.

What two data sources are commonly used to find relevant units of measurement to allow construction teams to calculate material quantities required / timescales for work programmes etc?

• Building Information Modelling (BIM) and traditional data sources such as drawings and specifications

• Online databases and construction management software

• Social media platforms and project management tools

• Mobile applications and cloud storage solutions
