Resurfacing of the Runway at Bandaranaike International Airport, Katunayake

POLICY AND PROCEDURES DOCUMENT

1. RUNWAY HISTORY

BIA has a single runway constructed and commissioned in 1986 under the “Colombo International Airport Development Project Phase 1”. It had been designed as ICAO Code 4-E for critical aircraft Boeing B-747 for a life span of 20 years with 10,000 movements per annum. The runway is 3,350 meters long and 45 meters wide (3,350 m X 45 m).

The runway has been in use for three decades now without comprehensive resurfacing or overlaying other than regular maintenance.

At the request of Director General of Civil Aviation (DGCA) Sri Lanka, the International Civil Aviation Organization (ICAO) mobilized an Expert Team in March 2001 to review the BIA facilities and infrastructure. The report submitted by the ICAO team had recommended inter alia the need for resurfacing of the runway.

The need for resurfacing of the runway at BIA has since been re-emphasized by subsequent ICAO missions and also independent audits conducted by the CAASL. However, the runway was continued to be used to serve international aircraft operations to date without any comprehensive resurfacing due to multifarious reasons.

The current runway surface shows some alligator cracks, which if left unattended while continuing to use the runway, might lead to a major failure of the surface condition resulting in a serious safety hazard. Hence it is vital that the runway resurfacing is carried out at the earliest instance available.

2. LEVEL OF CURRENT USE OF BIA

As per the BIA Summer Schedule of aircraft movements of 2016, there are 25 international airlines operating scheduled flights into and out of BIA. The airport has an average of 170 total aircraft movements per day. The airport serves an average of 60 movements of Heavy aircraft, 100 movements of Medium aircraft and 10 movements of light aircraft daily. The above numbers includes the aircraft movements of Sri Lanka Air Force which operates an average of 5 to 7 movements per day.

SriLankan Airlines operates an average of 75 flights into and out of BIA daily.

An average of 25,000 passengers and 300 metric tons of air cargo are handled at BIA daily at present.

3. POSSIBLE OPTIONS CONSIDERED

With proposed work plan brought up by AASL; the airport operator, for resurfacing the runway, a meeting was convened by DGCA on 21st September 2015 with the participation of senior officials of CAASL, AASL, SriLankan Airlines and Aircraft Operators Committee (AOC) in order to discuss the arrangements to be made for re-surfacing of the existing runway at BIA. At this meeting the need to minimize disruption of airport operations and inconvenience to airport users was underscored and possible alternate options available were discussed. The following options were looked at if the BIA runway was to be closed for resurfacing.

1. Use of Mattala Rajapakse International Airport, (MRIA)
2. Converting the current taxiway (which was the old runway) into a temporary runway
3. Construction of a new runway
4. Use of Ratmalana or any other existing airport

In view of the current level of operations taking place at BIA, current facilities at MRIA (which can handle no more than five movements per hour) were found to be inadequate to handle the total traffic that BIA handles at present. Hence the option of using MRIA during complete closure of BIA was ruled out.

The feasibility of converting the current parallel Taxiway into a temporary Runway and using it as the Runway for aircraft operations during the period of proposed runway resurfacing was discussed at length.

Considering the safety concerns highlighted at the discussion related to above proposal the DGCA appointed a technical team to conduct a Comprehensive Safety Assessment in this regard, before a decision is taken to convert the parallel Taxiway into a temporary runway.

The results of the above Safety Assessment showed that the proposal of converting the parallel taxiway into a temporary runway was not a worthwhile exercise from the viewpoints of cost, time and labor. It was also observed that the surface condition of the taxiway too has deteriorated over the years and is not in a suitable condition to use as a runway.

The feasibility of constructing second parallel runway at BIA before commencement of resurfacing of the existing runway was also examined. However due to non availability of vacant land around the airport and the excessive time that would have to be spent in deciding the location of the second runway coupled with the laborious workload involved in acquiring the required land, this proposal was identified as not being a viable solution for the immediate need of closing the existing runway for resurfacing.

Ratmalana airport and other domestic airports in the country do not satisfy the required international standards in many aspects and hence could not be considered.

4. PRESENT PROPOSAL AND ITS BASIS

A. As explained in section 2 above resurfacing the runway as early as possible is a critical requirement.

B. As there was no alternate solution to the need of full closure of the active runway for resurfacing activities, it was decided to select a portion of the day when the airport is having lesser number of operations for closure for the intended purpose. The airport operator, AASL decided that at least eight hours per day during a period of three consecutivemonths would be needed for the intended resurfacing work.

C. Therefore on perusal of the aircraft movement schedule of BIA, it was observed that during day time between 0830 hrs and 1630 hrs, the airport was having lesser number of movements. Accordingly it was recommended to undertake resurfacing of the existing runway within three months, closing the runway completely for all traffic from 0830hrs to 1630hrs daily. The period for this operation was decided as 06th January to 06th April in 2017 (both days inclusive).

D. This period was selected as the most suitable period for runway re-surfacing on account of the lowest average rainfall that is experienced by the country during this period (Source : Department of Meteorology).

The Cabinet of Ministers at its meeting held on 13th November 2015 granted approval for resurfacing of the runway by closing the operational use of runway from 0830 hrs to 1630 hrs for a period of three months effective from 06th January 2017.

5. EXTENT OF WORK INVOLVED

Present Proposal for resurfacing of the runway includes mainly the following items;

a. Replace deteriorated sections of the runway and taxiway structural pavements.
b. Overlay the runway pavement and widen runway shoulders to meet modified code F operations.
c. Overlay of the deteriorated sections of parallel taxiway and exit taxiways to meet modified code F requirements.
d. Replace the existing runway lighting system and cables with new runway lighting system with cables.
e. Replace the existing taxiway lighting system and cables with new taxiway LED lighting system and cables including new center line lights

As per above proposal runway resurfacing and associated work will be conducted during day time from 0830hrs to 1630hrs from 06th January to 06th April 2017. During this period the runway will be closed for all aircraft operations.

However Grandfather Rights (historical slots) would not be honored during this period and hence will be disregarded. Any deviation from the approved criteria shall be approved by the Chairman, Slot Committee in person. During the period of runway closure, the maximum departures that would be permitted within one hour would be 12 and arrivals would be limited to 10. Subject to the foregoing, the airlines were requested to submit their preferred slots for necessary coordination and approvals.
