Role and Duty of Professional Land Surveyor
1. Responsible to Principal Resident Engineer (PRE)
2. Lead, manage and supervise a team of professional land surveyor and Resident RSSOE/RSOE (Engineering) in all aspects of : -
a. Land
b. Engineering surveying;
c. GNSS;
d. ADMS;
e. Laser Scanning;
f. Hydrographic Surveying;
g. Geodetic Surveying;
h. Topographical Surveying; and
i. Photogrammetry.
3. Data capturing and data creation, quality data management and documentation.
4. Liaise with Contractors’ survey managers
5. Communication, Coordination and co-operation with engineers and inspectors on all work fronts
6. Ensure quality of data and hence quality of the works
7. Delivery quality of services
8. Safety
9. Training of young graduates to be RSOE and professional qualification

Present Situation
From Design Stage to Construction Stage
Generating and managing
from
2D working drawings
to
3D setting out and construction data
![Page 7: Name: Sr T. N. WONG FRICS, FHKIS, FCInstCES, RISM, MNZIS … Reality Modelling and... · 2018-04-25 · Humble introduction •Name: Sr T. N. WONG •FRICS, FHKIS, FCInstCES, RISM,](https://reader030.vdocuments.us/reader030/viewer/2022041015/5ec68b1a9e79340ed7665ad2/html5/thumbnails/7.jpg)
Present Process
Before Concreting/construction:
• 1. Setting out by the Contractor
• 2. Setting out check by Resident Site Staff (Surveying)
After Concreting:
• 3. Join as-built record survey
• 4. Compared these as-built record survey data with
design data to determine the quality of the work.
• 5. Report on the quality of workmanship and monitor
mitigation works to meeting the standard.
• 6. Final as-built record survey in 3D
• 7. Final quantities and final account.

Shortfalls
• 1. Difficult to check design faults due to lack of
existing ground information
• 2. Hard to detect clashes
• 3. Not easy to visualise
• 4. Rework or abortive work if not detected before
actual work being carried out
• So, We use “BIM” process to improve this.

Different Levels of Development in BIM
• 5. Involve potential claims
• 6. Possible delay
• 7. Increase cost and time
• 8. Untimely completion causes unnecessary
disruption to implementation of mega transport
systems or development programs
• 9. Possible negative social and economical effects
