Iterative methodology for Building Surveys
the Iteravite methodology collects data and from it determines the adequacy of the property
materials will be assessed by their suitability and condition during the survey.
Loadings and Foundations Survey
need be determined and how they are transferred to the foundation. The type of natural foundation will need to be researched.
Invasive v non-invasive Building surveys
Invasive v non-invasive survey The survey offered will be non-invasive and will advise of the adequacy of a property. An invasive survey may break into the fabric of a property and the property may require monitoring over time.
Adequacy of Property Survey
Adequacy of property survey Structural Surveyors determine the adequacy of a property by surveying their: Stability Strength Robustness Ductility Geometric permanence Stiffness Dynamic Response Resistance to fire and other accidental loading Weather-tightness Durability Apparent condition
Fe = Iron Survey
FE – Iron Survey FE = Iron Rust – iron + water + oxygen → hydrated iron(III) oxide = FE3+ When FErrous come into contact with oxygen and water they Rust · Iron + Carbon = Steel · Steel + Concrete = two materials with the same coefficient of expansion = re-inforced concrete = sky scrapers Protection… Continue reading Fe = Iron Survey
Functions of Elements Survey
Functions of Elements survey Functions of Elements: Strength, Stability, Weather tightness, Thermal, Sound, Durability and Maintenance, Fire, Habitability, sustainability, hygiene
Electron Movement, chemical bonding, ionic bonding and transfer Survey
Electron movement, chemical bonding, ionic bonding and transfer survey Electron Movement, chemical bonding, ionic bonding and transfer: Electricity, within central heating systems (Ion exchange to remove/break down/prevent scale), Electro Magnetic fields, Chemical reactions ( CO2 – Carbonation, Lime, Plaster – O2 – rust, H2O Hydration, damp, rot, Sulphate attack – stacks, flues and brickwork, Thaumasite, Ettringite, Alkali-silica… Continue reading Electron Movement, chemical bonding, ionic bonding and transfer Survey
Conduction, convection and radiation Survey
Conduction, convection & radiation survey Conduction, convection and radiation – The transfer of energy through the various states of matter; liquid, solids and gasses, and vacuums affect the building and occupants as follows: Thermal gain and loss, sustainable construction, Building Regulation compliance, Condensation and interstitial condensation, Building position and orientation, Light, shade, plant growth, mould, fungi,… Continue reading Conduction, convection and radiation Survey
