Introduction
In Palestine as in other developing countries in
the world, there is a natural high increase in
population. Such population growth requires
constructed facilities such as housing so,
Innovation new method to reduce cost.
4

• Importance of the project
• The overall aim of this project is to help
  the Palestinian companies to obtain low
  residential construction cost through using new
  method of construction.

5
Methodology
Research Question What is the new construction
method and alternative materials that can be used
in project environment.
6
Methodology

• Data Collection
• Previous study
• Interviews

the interviews that were made with engineers and
contractors that have experience about value
engineering to achieve the research purpose. .
7
Methodology
This table shows criteria's that taken when
evaluating construction material through give
each alternative material scores related to this
criteria and compare these scores to make a
decision.
1- Cost of construction 2- Cost of Material
3- Construction speed 4- Aesthetically
5- Safety during construction 6- Strength
7- Durability 8-Environmental
9- Fire resistance 10- Heat (Thermal) resistance
11- Shockproof 12- Sound insulation

8
Methodology
Case study

• Housing will be taken as a case study in order to
  estimate the actual cost using new material and
  new construction method and some management
  concept then compared with traditional methods.
• The Alternative materials that taken
• Cobaix System
• Artificial Stone
• Polyvinyl chloride (PVC) tiles
• PVC Windows
• PVC Doors

9
Methodology

• Using Revit 2014 software to measure a quantity
  of building before and after using alternative
  material.
• By primavera, input the quantities data and by
  estimated productivity rate, total budgeted cost
  and duration was calculated for previous cases.
• Apply Present Worth Analysis Method (PWA) to
  choose the best economical material.

10
Methodology

• Make an evaluation between alternative material
  and current material with take many consideration
  as mentioned above, according to
  Multiple-Criteria Decision Analysis method.
• Make a decision Alternative material is better
  than current material or NOT !

11
Discussion and Conclusion

• The different between costs before and after
  alternative materials is 77,860 approximately.
• According to PWA method, all alternatives were
  rejected economically, except PVC windows was
  accepted.
• In evaluation, the priority was taken for cost
  and time criteria, so its took high importance
  scores.
• Environmental and safety consideration were taken
  for each material, though it is not important for
  customers.

12
Discussion and Conclusion

• According to Multiple-Criteria Decision Analysis
  method, All alternatives were surpassed except
  cobiax system, although its reduce 17 concrete
  and 26 steel.
• Cobiax system will be more efficient if it is
  used in long spans such as hall, auditorium, and
  courts, but its not efficient for residential
  home.
• ? ? ? ?

13
Discussion and Conclusion

• Artificial stone overweigh on natural stone,
  although natural stone has a good specification
  and lifetime, but its unsafety, unfriendly with
  environmental.
• A PVC tile is better than traditional tiles, in
  spite of the high cost of PVC according to PWA
  method, but its has a good specification such
  as shock, sound proof and fire resistance. Also
  its easy to install.

14
Recommendation

• Customers must be aware about positive
  characteristics for new material to increase its
  demand, thus increase the rate of its industry.
• Making tradeoff between cost and other criteria.
• Encourage contractors and workers to keep in
  touch with development markets.

15
Recommendation

• Organizing workshops for contractors, engineering
  offices to aware them about alternative
  materials.
• Encourage the teaching staff in universities to
  mention and clarify the benefits of using new
  methods of construction and alternative material.
• Cooperation between local and global construction
  companies, to take experiences as much as
  possible and trying to apply it locally.
