ADP Ingénierie brought notably its experience in works under operations.


Opened in 1979, Taiwan Taoyuan International Airport has two parallel runways, located south and north of the two passenger terminals. Each runway has one or two parallel taxiways, several connecting taxiways and rapid exit taxiways. The airport has 38 contact stands for commercial flight, 20 remote stands, 25 cargo stands and two maintenance aprons for the two local companies China Airlines and EVA Air.

Since 1979, only current maintenance and enabling works have been done on the pavements, but no major rehabilitation works. Given that:

-  the pavements are reaching the end of their life,

- during the next two decades air traffic is expected to grow from the existing 150,000 annual movements up to almost 400,000 annual movements in 2035,

- the size, weight and wheel load of aircraft will increase (for example A380, B777 and further aircraft), inducing more impact to pavements than the present traffic.

MOT (Ministry of Transport) and TIAC (Taipei International Airport Company) decided major rehabilitation works of airfield pavement (taxiways and runways, but excluding aircraft stands). In the same time, another project included upgrading of NAVAIDS and Airfield Ground Lighting (from CAT I to CAT II for South Runway and from CAT II to CAT III for North Runway). Moreover, this rehabilitation allowed the airport to handle ICAO Code F aircraft such as A380. 

Our solution

In Joint Venture with Sinotech, ADP Ingénierie was in charge of the Detailed Design for the airfield civil works of the rehabilitation, including tender dossier production and assistance to construction supervision. Particularly, it included the detailed design studies for the full  pavement rehabilitation and upgrading (Aircraft code F compatibility) of the two runways and the taxiways systems associated and for almost all taxi lanes, South Runway extension (450m), new rapid exit taxiway, new remote apron (7 stands for aircraft Code E). It also required strips levelling and rehabilitation of drainage facilities and duct bank utilities.

After existing pavement evaluation, (based on soil investigation, testing and analysis; visual pavement distress assessment; Ground penetration radar and Heavy Falling Weight Deflectometer (HFWD) surveys), ADP Ingénierie/Sinotech proposed the following rehabilitation strategy on runways and taxiways:

  • Retain existing concrete slabs, improve subbase drainage and place asphaltic overlay after major preparatory works including slabs grouting and dowel bar retrofitting – for the South runway and approximately one third of the taxiways,
  • Remove the existing concrete slabs and rebuild a full new asphaltic pavement – for the North Runway and the remaining taxiway,

ADP Ingénierie/Sinotech proposed the following new pavement:

  • Asphaltic pavement for the runway extensions and the new rapid exit taxiway,
  • Portland Concrete Cement pavement for the new remote apron.

Moreover, ADP Ingénierie/Sinotech established the phasing scheme of works in order to maintain airport operations during the construction of work, to meet the required capacity level, including runway, taxiway and apron (stands) capacity and associated aircraft movements, ensuring the highest level of safety for all aircraft operation. As such, the studies also included a traffic impact analysis via CAST simulation and a traffic maintenance report, detailing aircraft movement on the whole airport and safety issues during the construction works such as works area signing, marking and closure, etc.

Detailed design and tender documents preparation were completed in June 2014. Assistance to Construction Supervision have been carried out from 2014 to 2018.

ADP Ingénierie has carried out the following tasks in Design Phase (October 2012-June 2014) of the project:

  • All aspects of pavement design issues (pavement investigation, analysis and design options and detailed design, airside geometry, etc.),
  • All aspects of airside operations during works (traffic impact analysis via CAST simulation, traffic maintenance report, phasing of the works, etc.),
  • Coordination with the design of drainage improvement and utilities (made by our associate firm Sinotech),
  • Coordination with the Contractor in charge of the Design and Built of Airfield Ground Lighting (CAT I to CAT II for South Runway and from CAT II to CAT III for North Runway) (independent contract),
  • Preparation of tender documents (drawings and specifications).

In design Phase (2012-2013) ADP Ingénierie provided a Resident Engineer in Taiwan, in charge of project management and coordination between ADP Ingénierie and Sinotech, and between ADP Ingénierie and the client and the other relevant projects ongoing in the airport.

In Construction Phase (2014-2018), ADP Ingénierie provided technical assistance to the client and the General Consultant in charge of the supervision of works, which included all issues directly related to the design (change order, etc.) as well as operational assistance (AIP-NOTAM publication, aircraft movement, etc.).
