Rehabilitation of Drainage Channels and Arrangement of Drainage and Strip Areas Project

Point Project Engineering is successfully carrying out a comprehensive engineering project aimed at improving runway safety, surface water management and environmental infrastructure at Balıkesir Koca Seyit Airport. The project has been designed and implemented in accordance with ICAO Annex 14 and SHGM (General Directorate of Civil Aviation) standards that ensure aviation safety and infrastructure continuity.

Scope and Target of the Project

This project has been developed in order to rehabilitate the existing open drainage systems and ensure the sustainability of airport operations without being affected by meteorological conditions; at the same time, to increase flight safety by making arrangements at runway heads, RESA sites and strip areas.

The studies carried out include both the safe evacuation of surface waters and the expansion of the Runway End Safety Area (RESA) areas in accordance with ICAO requirements. In addition, the modernization of the auxiliary structures around the runway and the safety infrastructures are also among the important components of the project. Dec.

Technical Works Performed

1. Rehabilitation of Drainage Systems

In the current situation, the open surface drainage lines drained through the soil floor were causing the site to be flooded during rainy periods and disrupting vehicle-pedestrian transportation. To solve this problem:

• The existing uncoated open channels have been re-projected with a trapezoidal section and their inner surfaces have been converted into an open channel system with concrete coating.< / li>
• C30 class concrete coating is envisaged for the channel floor and side surfaces, high strength and long life are aimed.< / li>
• Especially on the 0-5 runway head approach lights side, a special inclined channel design was made to prevent water entry to the approach zone and was supported by steering slopes.< / li>

With these studies, surface water management in the areas around the runway has been activated, water accumulations and flood risk have been eliminated.

2. Arrangement of RESA and Strip Fields

• At the beginning of runway 0-5 and runway 2-3, RESA (Runway End Safety Area) areas were designed and added to the field in accordance with ICAO standards.< / li>
• In these areas, the necessary denim arrangements, compact filling applications and mechanically stabilized material laying were made; the minimum 90 meter length and 150 meter width requirements of RESA sites were met.< / li>
• Within the scope of the regulations made on the strip areas, surface coatings that reduce the friction value have been made from the edge of the runway and made in accordance with the obstacle free zone (OFZ) criteria.< / li>
• In addition, the approach lights infrastructure has also been renovated within the scope of the RESA expansion works. The new approach lights are designed to provide the photometric performance required by the civil aviation authorities, both by taking into account the difference in elevation and by being mounted on a durable platform.< / li>

3. Environmental Reinforced Concrete Applications and Infrastructure Improvements

Within the scope of the project, environmental arrangements of various structures have been made throughout the airport:

• The perimeter of the 21 sentry huts has been covered with concrete in order to create sealed and rigid platforms.< / li>
• The perimeter of the 7 transformer buildings has been surrounded with reinforced concrete floor to provide ease of access and maintenance, both waterproofing and static resistance have been observed.< / li>
• The wind cone has been concreted around as a maintenance and viewing area; the stability of the device has been increased with a smooth sloping surface.< / li>
• In addition, 6 turn pockets have been built along the perimeter safety road. These pockets allow emergency vehicles to maneuver and increase the effectiveness of perimeter security patrols.< / li>

4. New Transportation and Connection Roads

• A connecting road has been built between the bomb Deconfliction pit and the existing service roads. This road has been stabilized with infrastructure layers suitable for a 5-ton axle load and has been prepared in such a way that it can be converted into concrete pavement if necessary.< / li>
• 0-5 an emergency exit door connection path has been made to the approach lights side of the runway to provide transportation for security and maintenance teams.< / li>
• All roads are designed with antistatic coating alternatives in mind so as not to create electromagnetic interference around the airstrip.< / li>

5. Stream Crossing and Culvert Design

• 0-5 The culvert structure has been designed for the stream crossing located on the side of the runway head, and hydraulic calculations have been made based on the minimum 100-year flood flow rate here.< / li>
• The culvert section and the over-road crossing will be finalized as an implementation project after coordination is established with the relevant public institution (DSI or Highways).< / li>
• 0-5 runway head approach lights path type cross section will be based on the road surface coating detail and layer thicknesses.< / li>

6. Environmental Safety and Site Cleaning

• Within the scope of the project, the production of wire mesh with concrete posts was carried out on top of the reinforced concrete curtain walls located at the site boundaries. This production serves as both a visual barrier and a physical barrier in areas with a high security level.< / li>
• Machine cleaning and dismantling works were carried out at the sites determined in the project area; earthmoving materials were disposed of in a controlled manner, and the remaining areas were stabilized.< / li>
• Disassembly and reassembly works for operations such as disassembly and renewal of approach lights were carried out in accordance with the field procedures of SHGM and DHMI.< / li>

Result

With this project, Balıkesir Koca Seyit Airport has achieved RESA and strip areas in ICAO standards, the surface drainage infrastructure has been strengthened, and the ground security of the runway and environmental structures has been increased.

Point Project Engineering has reflected the technical know-how it has developed on the rehabilitation of airport infrastructure to this project; it has implemented a highly qualified infrastructure system that increases operational safety and environmental sustainability with solutions based on field data.
