2. MATERIAL MANAGEMENT
1. A key factor adversely affecting project
performance is the improper handling
and management of materials for that
project.
2. Materials management is more important
on fast-track projects.
3. Design and procurement decisions are
made concurrently with construction
activities.
3. MATERIAL MANAGEMENT
material
management
• Many clients aim to finish their project
as fast as possible in order to gain a
faster return on their investment.

management
• Fast-track production involves the
reduction of time from the normal
duration of project activities.
5. MATERIAL MANAGEMENT

• An integrated material handling
process from the design stage to
the usage of materials is needed.

management
9. MATERIAL MANAGEMENT
The result of improper
handling and managing
materials on site during a
construction process will
influence the total project cost,
time and the quality.
10. MATERIAL MANAGEMENT
Costs for materials
handling may
range from 30-80%
of total
construction costs
Almost 60% of the
total working capital
of any industrial
organisation
consists of
materials costs
11. MATERIAL MANAGEMENT
There is a need for efficient
materials management in order
to control productivity and cost
in construction projects.
Poor materials management can
be summarised as:
13. MATERIAL MANAGEMENT
Lack of a proper
work plan
Inappropriate
materials delivery
Excessive
paperwork
Receiving
materials before
they are required
14. MATERIAL MANAGEMENT
This will cause more inventory
cost and chances of
deterioration in quality
Not receiving
materials at the time
of requirement
This will cause
productivity decline
Incorrect materials
takeoff from drawing
and design
documents
17. Material management route
Fig. 2.11 Typical adverse material management (Thomas et al, 1989)
Poor organisation of
storage area on site
Extensive multiple handling
of materials
Material badly stored or
marked
Poor House Keeping
Wastage on
Site
Access to storage area
obscured by debris
Lack of planning of material
deliveries
Lack of co-ordination between the
time of deliveries and erection
Remobilization and re-familiarisation
after a lengthy delay
Running out of
materials
Lack of anticipation about
material shortage
Material management
20. PLANNING
Planning
• An appropriate materials planning to be
done concurrently with engineering,
construction, and other project plans.
Planning
• Material planning would provide guides
to all the subsequent activities.
21. PLANNING
Planning
• Material Planning could have a
great impact on the project plan
Planning
• Planning of access and routing
of materials within a
construction site
22. PLANNING
It has an important implication for the
development of an effective materials
management strategy
Procurement
23. PROCUREMENT
It includes purchasing of :
equipment
Materials
Labour
Including, services required for construction and
implementation of a project
24. PROCUREMENT
The objective of procurement in materials
management is to provide the materials in
the right time, place, quality and an agreed
budget.
Procurement is about organising the
purchasing and issue delivery schedules
to suppliers and following-up to make
sure that suppliers deliver on time.
29. EFFECTIVE MATERIAL HANDLING
Construction Materials Exchange (COME)-
Commerce system for material procurement
Construction Materials Planning System (CMPS)
Material Handling Equipment Selection Advisor (MHESA)
30. EFFECTIVE MATERIAL HANDLING
Maintain good vertical site access
Consisting of cranes, hoists, lifts, pumps, ladders and stairs to
form double handling for vertical handling
Bar-code system - for material storage application
Extra space for the site compound
31. EFFECTIVE MATERIAL HANDLING
Good access for material/plant deliveries:
comprehensive facilities for transport arrivals and
departures.
Keep the site compound well surfaced, well
organised, clean and tidy
32. EFFECTIVE MATERIAL HANDLING
• Delivery of bulk materials in large:
transportation for large quantities by rail
(e.g. reinforcement/steelwork) or barge
(e.g. ballast from a dredger) and for large
volume by pipeline (e.g. water/gas/oil/
chalk/cement/concrete) or conveyor
(e.g. excavated material/fill).
