week 7 Flashcards
3 types of maintenance include
Planned maintenance
Routine/ cyclical maintenance
Reactive maintenance
describe planned maintenance
Planned maintenance: The items included within this category are those which are planned to take place at defined, regular intervals in order to keep the building in good order. Examples may include:
Recovering of flat roofs
Replacement of boiler components/pumps etc.
Overhauling of windows
Repointing of external elevations
describe routine / cyclical maintenance
Cyclical maintenance: This category includes items that must be dealt with routinely and regularly to maintain the building in good condition. Examples may include:
Cleaning gutters and drainage gullies
Servicing of mechanical and electrical components
Renewal of protective coatings
describe reactive maintenance
Reactive maintenance: Items within this category include day to day items of repair and breakdown of plant and machinery. Examples may include:
Replacement of broken glazing units
Repairs to leaking roofs
Treatment of vandal damage
describe deferred mantenance
Is the practice of postponing maintenance activities such as repairs in order to save costs, meet budget funding levels, or realign available budget monies.
Failure to perform needed repairs could lead to asset
deterioration and ultimately asset impairment.
Generally, a policy of continued deferred maintenance may result in higher costs, asset failure, and in some cases, health and safety implications.
Household example?
explain facade retention system
Facade retention involves supporting existing façades or party walls for renovation and is often used for works to listed buildings.
A steel structure or scaffolding system is attached to the face of the building through openings of the building such as doors or windows.
The façade system is also anchored to the footings to act as a counter lever. They are common for heritage buildings as any rebuilds usually require the façade to be kept for heritage purposes.
Once construction of the internal structure is complete, the existing façade can be connected to it
By retaining the façade, the overall look of a building is preserved while new internal floor structures and layouts can be constructed to meet the needs of modern occupants.
The factors that need to be considered include:
length of proposed works
height of the building,
access to the site for vehicles and pedestrians
ability of anchor and attachment points to the building
types of rentention include
Scaffolding, suitable for low level facades between 3 and 4 storeys, with sufficient space at their base for installation.
Proprietary retention, involving props, ties and bracing suitable for higher facades as the general quantity of components are reduced.
Fabricated steelwork, used when cost of hiring proprietary equipment over long periods of time outweigh the cost of fabricating a structure
Combinations of fabricated and proprietary retention systems.
what is a liquid water proof system
Waterproof coating to commercial roofing helps – assists with extending the roof life and prevents water entry to the building
The main advantage of liquid waterproofing systems including;
Minimal disruption as the existing substrate is usually left in place
The ability to cope with irregular surfaces
Ease of installation & cost effective
Can be applied to a range of materials including concrete, timber, steel and fiberglass
liquid water proof system not suitable iff
The substrate is not clean and dry
The existing deck and any insulation is not dry and structurally sound
The existing membrane will not bond with the new material
The existing deck will not take the additional loadings

define facilities mangement and explain some of the role they may undertake
Facilities Management is a profession that encompasses multiple disciplines to ensure functionality of the build environment by integrating people, place, process and technology (International Facility Management Association).
