Hypothesis of Graduating project 2:

compare between two bids for the same project: ** the first one is estimation equal to 1.548.600 ILS, ** the second is estimation equal to 1.804.600 ILS.

Location of the project :

AnabtaIt’s a Palestinian city is considered one of the largest

cities of Tulkarem, a town divided into two parts:

**the old town which is located in the center and houses built by 150-100 years, the population of the old town 2000 people,

**The rest of the areas some are built from 50-70 years and the other newly built during the last twenty years, and the town has a population of 7000 new people.

** The town has a population of about 9000 people (2010)

Installation of pipes

Installation and Welding of pipes and accessories along the route of pipelines , and welded joints must be wrapped by using sleeves

Sample on Comparison between two bids

Supply of pipes For bed A When Contractor A, calculated the

amounts, he depended on the Israeli cost since it is cheaper and has all the specifications. And after taking the bid, it was found that the Palestinian Water Authority prefers the national industry so it was agreed on the Israeli cost between the contractor and the factory, and on the same specifications.

  

Page 16: An- Najah  National University Faculty of  Engineering Civil Engineering Department

For bed B,

When contractor B, calculated the amounts, he from the beginning depended on the Palestinian cost even though it is more expensive and has all the specifications .

Page 17: An- Najah  National University Faculty of  Engineering Civil Engineering Department

• Earth works

For bed A the contractor want to rent all machine which he need to complete the work .

For bed B•the contractor have all machine which he need to complete the work ( he don’t need to rent any machine )

Page 18: An- Najah  National University Faculty of  Engineering Civil Engineering Department

Conclusion :1) The increase in the number of the contracting corporations in the Palestinian market led to bids less than the estimated cost, since many corporations calculate the bid as to cover all their overhead expenses in order to guarantee it’s place in the market and to keep the employees working for these corporation through covering their salaries and expenses.

Page 19: An- Najah  National University Faculty of  Engineering Civil Engineering Department

2) The decrease in the number of the bids in markets in contrast with

the number of the existing corporations because of many external political reasons which

aims to affect the internal economical policies of Palestine.

3)Sometimes , it’s not the gains which comes in the first place for

the contractors, but it’s the reputation which matters to them

specially when they are fresh contractors or the corporation

which they belong to is fresh and new.
