pre-tension) that we used in our project .the benefit of pre-stressed girder

.reduce the depth and reinforcement of beam and economicare

5.1.3.2 post-tension: is used in our project and it is the commonly used were the

tensioncable put in metal ducts. After hardened of concrete tension the

cable to the required strength by using special equipment and then injection

the grout into the pipes to fill the voided in the ducts.

5.1.3.3 check the reinforcement of girder and put in the ducts.

FIELD PROBLEMS-6


48/57

SAND CONE TEST:1

Has been tested a sample of sub aggregate at the site using the sand cone method to

make sure you moisture density of soil verify ministry's standards, or not? And

the problem by refusing toresolvefound it does not meet the specifications was to

receive sub aggregate layer and re-processed.

PARRAPETS REINFORCEMENT:2

When matching schemes for reinforcing parapets We found that there is a

the problem byresolvedifference between reality and reinforcing scheme was to

refusing to receive the reinforcing parapets and make sure reinforcing some

parapets already installed.

CROSSHEAD CONCRETE:3

After casting 40 cubic meters of concrete for the crosshead and taking samples

from the site to test compressive strength of concrete show that the concrete did not

achieve the force required in the design and then used a Schmidt hammer also did

the problem byresolvenot achieve the force required in the design and was to

refused to receive the crosshead concrete and then broken crosshead.

STREET:-KING FAHAD ROAD INTERSECTION WITH EIGHTY4


49/57

STREET:-KING FAHAD ROAD INTERSECTION WITH EIGHTY4

After delivery to bridge the intersection of King Fahad Street, with eighty-street

there was a lot of traffic problems and complaints from citizens because of

the problem by modifying some of thesolvedcongestion and designs, then

designs.RAINFALL WHEN PLACING CONCRETE:5

The occurrence of rainfall after casting concrete directly and did not reach the stage of

the problem by putting a plastic insulator during thesolvedhardened concrete, and

rains.

MORTAR OF BLENTH:6

During the beginning of mixing materials and cast of blentgh found that there is

toresolvedan increase in workability due to increased water and the problem was

refuse the receipt of materials.

KING FAHAD ROAD ITERSECTION WITH KING ABDUL AZIZ :7

During the implementation of a bridge and tunnel at the intersection of King Abdul Aziz

Street and King Fahd Street, found that isolated footing of the bridge, prevent the

by replacing the isolated footingresolvedestablishment of tunnel and the problem was

by piles footing.

Conclusions

Conclusions

Coop training is very useful in providing students with valuable onsite

professional experience.

Lab and field experiments are considered essential tools for engineers in order to

assure the quality of different field engineering activities.

Engineers have to consider the site conditions carefully, among other factors,when planning and managing engineering projects.

Engineers need to learn how to be successfully in dealing with multidisciplinary

professionals at all levels.

Communication and effective team work are essential for onsite work to assure

success.
