project name:
The seventh (hydrographic) project by air and by sea for the coastal region in the Arabian Gulf confined
between Dammam to Doha Salwa.
Project Type:
hydrographic project
Duration of the project: 9 months
Project end date: 13/01/2016 m
Project scope of work:
- Establish geodetic Control Network, Tide Gauge Network and vertical Datum points, and perform the
necessary monitoring to cover the survey area.
- Determine the expected Tide range and direction of currents, with
study and analysis of Tide data and its characteristics in the survey area.
- Equipment for marine
survey and treatment programs must be modern, so that they do not exceed 3 years old from the
start of the project, and this must be clarified in the submitted offer, and this may exceed
that which proves that the proposed devices have the same quality and ability to collect
data.
- Airborne LiDAR system to
cover the coast (3 km) extended to land for geographical connection between the sea and land
(Bathy / Topo)
- Covering the defined
shallow coastal areas between high and low tides, islands and coral reef areas.
- Port areas in the Red Sea
should be surveyed according to International Hydrographic
Organization(IHO)specifications.
- Providing marine survey
ships with a comprehensive depth monitoring device, for depths exceeding (20) meters, and
merging them with data that were monitored using Radar to ensure that there is 100% full
coverage of the area taking into consideration the high turbidity in the Red Sea.
- All data of the LiDAR and
the comprehensive monitoring device must be of high accuracy and clarity for all areas of the
project in order to ensure full coverage of the area and the absence of voids.
- Use the two Observation and side monitoring devices to ensure
navigation obstacles at the bottom.
- Use the comprehensive
monitoring device to collect bottom classification data and compare it with the collected
samples from the bottom.
- Use a shallow penetration
device.
- The contractor must
provide the Commission with detailed information, specifications, and photographs of the
aircraft and marine survey boats used to obtain the necessary permits.
- The aircraft, ships,
hydrographic devices and the method of implementation will be evaluated, along with adding any
other criteria that the commission deems appropriate.
- hydrographic devices and
marine vessels are subject to examination by a team from the commission.
- Coastline identification
(high tide monitoring, low tide monitoring) and landmarks.
- All work involved (data
collection, processing, auditing and field verification) must be carried out strictly according
to IHO specifications.
- The hydrographic ship
must be eligible for the survey and equipped with a marine electronic mapping system, as well as
the plane equipped with LiDAR, so that it is qualified and conform to the specifications of the
Civil Aviation Authority in the Kingdom of Saudi Arabia.
- The contractor must
perform quality control and assurance work for all data during survey work and after completing
survey work and attach a separate report for quality control and assurance work.
