Due to an increase in both the number of passengers and demand of wide-body aircraft arrival such B777-300, DPS runway needed to be extended and upgraded to give a service of direct flight to Europe and increase Indonesia tourism sector. Scope of this projects are Runway 09/27 extension (400 m) to the west side towards the offshore, Extension of service road (2000 m) and perimeter fence following the new airport boundary on land reclamation, Establishment of new drainage line as well as integration to the current drainage system, Offshore girder bridge construction for approach light system, Upgrade Airfield Lighting (AFL) System.
Description of actual services provided within the assignment
Survey works such as topographic survey, geotechnic survey / soil investigation, bathymetric survey, hydrological survey, ground penetrating radar (GPR), pavement classification index (PCI) and also review of existing pavement and layering data.
Maritime engineering studies for coastal protection of the runway and design calculation for offshore bridge structure (soil data analysis, deep foundation bearing capacity, stability and strength of pile foundation at offshore, etc.)
Design services and preparation of detailed design for the extension of west side Runway 09/27 (400 m extension), upgrade the pavement of the existing runway, creation of runway end safety areas.
Obstacle limitation surfaces studies to calculate the height of permissible of the approach light bridge (include studies of the related influence aviation safety aspects of Instrument Flight Procedures, Visual Flight Rules (VFR) Route and Helicopter Procedures, etc.)
Planning lighting for access roads and perimeter fencing.
Planning for completeness of electrical facilities, including analyzing the capacity and existing airfield lighting network, as well as planning a new network of threshold and wingbar lights, runway & taxiway edge/insert lights, runway approach lights using precission approach lights system category 1 (PALS CAT 1), Squence Flashing Lights (SQFL), PrecisionApproach Path Indicator (PAPI), Movement Area Guidance Sign (MAGS), Runway Guard Lights (RGL), Instrument Landing System (ILS), etc.)
Planning a new drainage system that is integrated with the existing drainage system (including sub-drain) and still able to meet the capacity of the catchment area, as well as planning the structure of open and closed drainage channels required.
