Essential Tools for Measured Drawing Surveys
For conducting a survey that involves measured drawing, the key instruments required include:
A 30m steel tape, 2m folding survey rod, and a 2m flexible steel tape.
If measuring and replicating moldings, a piece of Code 3 sheet lead approximately 25mm wide and around 800mm long is necessary to create an accurate template by molding it against the molding to capture its shape and details.
3D survey scanner
Telephone or camera for capturing images
A 2m bricklayers level and straight edge
An A4 tracing paper sketch pad or a tablet for sketching
Appropriate attire (e.g., old clothing, boiler suit, or nylon slip-over trousers) should be worn, avoiding wearing your best clothes.
Personal protective equipment
A pair of binoculars can be helpful for inspecting roofs, parapets, and chimney stacks
A small pocket compass for verifying the property's orientation
An electric torch
Equipment Required for Surveying Buildings and Inspecting Defects
The necessary equipment should encompass the following items:
Telescopic ladder
Electronic moisture meter
Laser distance measuring device
Plumb bob for checking the vertical alignment of walls and columns
2-meter-long straight edge for assessing the flatness of floors and walls
Magnifying glass
Compass for verifying the orientation of the property
Inspection cover keys
Palm-sized mirror on an extendable handle for inspecting hard-to-reach areas
Hammer or chisel
Screwdriver
Bradawl or probe
Spare sets of batteries for cameras, meters, and torches
First aid kit
Specialized equipment
Endoscopy: A fiber optic borescope is a valuable tool for building surveyors to inspect hidden voids and cavities for issues like bridging wall-tie corrosion and fungal attack (Hollis, 2005)
Electric drill
Electronic hygrometer: This device is crucial for investigating condensation dampness
Cover meter: Engineers and surveyors utilize this inspection tool to detect the presence and depth of steel bars in reinforced concrete
Calcium carbide ("Speedy") moisture meter: This tool is employed on-site to determine the moisture content of particulate building materials such as mortar, bricks, stone, and concrete
Plastic sample bags: These are handy for collecting samples of mortar, bricks, and other materials for laboratory tests
Socket tester: Used for conducting earth safety tests, voltage, and wiring checks
Micro-drilling: An expensive yet highly effective method for identifying decay in structural timber using special low-voltage hand drills that produce results in the form of a resistograph. Sorbus International offers such a drill IML-RESI F-Series.
Impulse radar or ultrasound: This specialized non-destructive technique can determine the extent of void areas like flue routes, hidden or blocked spaces. It can also identify leaks in roof and wall elements
Thermography: Infrared thermal cameras can be utilized as a non-destructive way to identify areas of heat loss, voids, or leaks in a building's external structure (Douglas & Ransom, 2007). Similar to impulse radar, it is a specialized technique typically reserved for specific cases, such as large commercial or residential buildings
Paint thickness gauge: A specialized handheld device for measuring paint coating thickness to the nearest 2 micrometers. It is suitable for testing paint coating thickness on any building surface
