The benefits can be short term or long term and can be reflected in the
areas of physical, financial or human resources.
A. Maintenance will preserve the physical characteristics of a building and
its
services.
ā¢ fewer breakdowns and lower future maintenance costs,
ā¢ higher productivity,

MAINTENANCE
PLANNING
20. It was important that buildings continue to be
properly maintained to ensure that they can
function as efficiently and effectively as possible
the deterioration of buildings due to
the lack of maintenance could lead
to future financial burdens, pose
legal and other industrial relations
issues and affect the delivery of
services
Identifying building problems and understanding
of building materials and its mechanical and
electrical systems are aspects of the process of
preserving and conserving building quality and
to ensure the efficiencies of the facilities
Is building maintenance important?
ā¦ā¦ why?

21. Building maintenance can also be categorised according to who
carries out the maintenance work:
housekeeping maintenance
carried out by property managers; or
second line maintenance
carried out by specialist building trades people.

PLANNING
28. Why have a maintenance
plan?
y
The main reason for a maintenance plan is that it is the
most cost-effective way to maintain the value of an
asset. The advantages of a plan are:
ā¢ the property is organised and maintained
in a systematic rather than ad-hoc way;
ā¢ building services can be monitored to assist
their efficient use;
ā¢ the standard and presentation of the property
can be maintained;
ā¢ subjective decision making and
emergenc corrective maintenance are
minimised.

MAINTENANCE
PLANNING
31. Periodic inspection
survey
ā¢ All properties should be inspected at regular intervals to identify
any deterioration and required maintenance work, including
cleaning
ā¢ maintenance was inappropriate or if there are design or material
defects
ā¢ All records should maintained for reference
ā¢ Advantageous to record the long-
term performance of repair
materials and procedures in order
to assess their suitability for future
maintenance work
MAINTENANCE
PLANNING
32. Maintenance
review
The effectiveness of the maintenance work shall be reviewed regularly. An
important part of the maintenance planning for a building is to improve the
previous decisions to maintain the asset so that subsequent maintenance
expenditure will be more effective
Issues to consider when reviewing the work include:
ā¢ was it necessary or appropriate
ā¢ the timing and standard
ā¢ time frame of the
planned maintenance
work
MAINTENANCE
PLANNING
33. Preparing a
budget
Annual budgeted expenditure on maintenance can be of
three kinds:
committed expenditure, which includes tasks that occur
every year as part of planned maintenance, such as
maintenance contracts;
variable expenditure, which includes regular tasks
within an overall program of planned maintenance that
may not occur every year. The building manager
exercises some discretion and decides on priorities for
these tasks;
managed expenditure, which relates to
unplanned maintenance works carried out
entirely at the building managerās discretion
The aim of a maintenance budget is to reduce managed
expenditure over time as far as possible and replace it with
variable expenditure. Regular inspections can help by
identifying how components are performing and when they
might fail.
MAINTENANCE
PLANNING
35. Preparing a
program
At least two levels of programming are required:
ļ¼ long term maintenance
cycle, which can extend to 50 ā 100 years of a building life
ļ¼ annual maintenance
annual inspection survey, day log book or diary and work
carried over from the previous year. The daily response
system for carrying out urgent maintenance should be
upgraded annually.
MAINTENANCE
PLANNING
36. Priorit
y
This implies setting priorities for different works. Some of
the factors affecting priorities are:
ā¢ occupational health and safety
ā¢ security of premises
ā¢ statutory requirements
ā¢ vandalism
ā¢ increased operating costs
ā¢ loss of revenue
ā¢ disruption to business operations
ā¢ likely failure of critical building fabric
ā¢ policy decisions.

MAINTENANCE FACTOR DESIGN
STAGE
Common Faults by
Engineers
ļ± most designers claimed to have knowledge and experience on
building maintenance aspects but only few are aware of the
importance to consider maintenance factors during design stage
ļ± main problems that the maintenance firms are currently facing are
caused by building design deficiencies, poor construction quality
and poor performance of building which is directly related to
functional layout, choice of building material and choice of building
equipment
ļ± Lack of communication between designer firms and maintenance
firms as well as building users or owners resulted in designer firms
not fully aware of the maintenance-related problems frequently
reported by building owners
ļ± neglecting the benefits of designing for ease of maintenance
that can prolong the building lifespan, reduce defects rate and
therefore reduce maintenance costs.
ļ± to develop awareness and policy from the very early start of
project to ensure the concept for ease of maintenance can be
understood and implemented successfully

ā¢ wear and tear effect on the component,

74. CRITICAL SUSTAINABILITY FACTORS IN
ENGINEERING INFRASTRUCTURAL
MAINTENANCE
(i) Previous users action (Vandalism):
Among the factors adduced as responsible for act of vandalism are wrong
choice of materials, poor space layout, poor lighting arrangements and lack
of security among others. Vandalism impairs the aesthetic of building, and
reduces its life span and cost intensive.
(ii) Environmental stress effects on infrastructure:
Climatic conditions impact stress building and occupants. Acts base on
orientation of the structure and on external elements of the structure. The
resultant effect on the building is referred to as sick building syndrome.
(iii) Deficiency in design construction and interdependency of building
components:
The nature in which some elements in building were designed often
hinders their maintainability. The most effective maintenance strategy
should be one that minimizes the incidence of maintenance works
through appropriate design. To be able to sustain a design or
concept, it should be maintainable, and maintainability in the real

76. THE RISK OF
FLOODING
historic buildings still can be affected by flooding and it is useful to
identify the causes and risk factors so that cost effective remedial
measures can be taken
Waterfront sites
structures were expected to be intermittently flooded, and those
that have survived often include materials and design features
that have allowed them to withstand intermittent flooding
Coastal sites
can be flooded due to breaching of sea defences or 'backing
up' of floodwater by high tides.
Ground drainage
buildings suffer flooding due to defective or poorly managed ground
drainage. On a local scale, this is commonly due to rising ground
levels and defective street drainage, which may allow local surface
water to 'run off' and drain into, rather than out of, ground floor or
basement structures
Roof drainage, services and building failures
due to failures of roof drainage systems or other building

77. Structural Maintenance and Planned Surfacing
Works Road / Highway
Structural maintenance and resurfacing restores the
fabric and the structural life of the highway thereby
protecting the asset. Increased traffic flows have
resulted in greater wear and tear and heightened the
need to monitor condition and prioritise treatments at
suitable intervention points.

78. Sewera
ge
Backing up and overflow of foul water and sewage systems are a not
uncommon consequence of flooding. The decontamination works
required then have a significant effect on the cost of refurbishment
and the length of time to re-occupancy.
The installation of additional breather vents and manholes may reduce
this risk, and detailing of access and drainage to under-floor spaces
or cellars can reduce the cost of decontamination. It is also important
to cheek that the system conforms to all building regulations, British
standards and bylaws.

79. Marine Structural
Maintenance
For many owners of waterfront
facilities, the marine structure is
the essential component of their
operation, without which their
business operation could not

at frequent, planned intervals.

ā¢ Identify risk factors by enquiry and site investigation
ā¢ Risks reduced by repairing or re-detailing (re-designing).
ā¢ Handle matters out of the direct control of building owners. i.e.
