Preface
We would like to express our greatest appreciation to all people who had helped one way or another in this report of refixation and sub-division.
First of all we are grateful to Allah because finally this report is already done. We also would like to thank to our sweet lecturer Miss Ashnita Rahim for teaching and leading us to do this report very well. Besides that, we also want to express thankful to all members because of helping and giving us supports in finishing this report.
Not forgotten to Geomatics Science Department and their staffs for the support and cooperation throughout using the instruments.
Last but not least we thank to all of our members mawi, emkay, hasbullah, amierul and kak ana for giving us to use their laptops and printers with free service. Without them, we can’t finish our report yet. We also would like to thank to all members for their dedication and commitments to complete this report.
We are confident this report will be a valuable resource for coming soon students to archive more knowledge in cadastral surveying. To the entire group member, congratulation and thank you for a good job. Well done!!
Thank you


Introduction


THE CHAIN-- There are two kinds of chain in common use, the Surveyor’s (or Gunter’s) Chain, and the Engineer’s Chain. Gunter’s chain is 66 feet long, and its use is confined chiefly to land surveying on account of its simple relation to the acre and to the mile.
1 Gunter's Chain = 4 Rods = 100 Links
1 Mile = 80 Chains
1 Acre = 10 Square Chains
Evidently each link is 66/100 of a foot (or 7.92 inches) long. The inch, however, is never used in surveying fieldwork.
The engineer’s chain is 100 feet long and is divided into one hundred links of one foot each. Each end link is provided with a handle, the outside of which is the zero point, or end, of the chain. In these chains, every tenth link counting from either end is marked by a brass tag having one, two three, or four points corresponding to the number of tens which it marks. The middle of the chain is marked by a round tag. In the engineer's chain then the 10-ft. and 90-ft. points, the 20-ft. and 80-ft points, etc., are marked alike; hence it is necessary to observe on which side of the 50-ft. point a measurement falls in order to read the distance correctly. Distances measured with the surveyor’s chain are recorded as chains and links, (or in chains and decimals); while those measured with the engineer's chain are recorded as feet and decimals.
On account of the large number of wearing surfaces and the consequent lengthening with use, the chain should be frequently compared with a standard of length ... It may be adjusted to agree with the standard, by means of a nut at the handle, which allows the length of the chain to be altered by lengthening or shortening the end link.

Conclusion
As conclusion, it is not easy to carry out the refixation on the survey works. There are many terms that we should apply in our works prepared by Survey Regulations 2002. In the site, we have to do the traversing as accurate as possible to avoid the error occurs. Refixation is important to make sure the boundary marks are in their original positions. We also have to replace the boundary mark that is found missing. Refixation is also important to establish later survey works like the sub-division and partition to get the control points. For every boundary mark planted, we have to do the checking to make sure that it is planted exactly on its position. If the boundary mark is not in the correct position, then it is need to be re-established again. The most important thing is to find the suitable baseline that can be paired to the third mark. The differences of the interior angle between baseline and third mark are 10”. If we did not found it to the nearest boundary marks, then we have to travel to the other boundary marks until we get the best baseline with its third mark.
