DESCRIPTION OF APPROACH, METHODOLOGY AND WORK PLAN FOR PERFORMING THE ASSIGNMENT
4.1 Introduction
Nepal, officially the Federal Democratic Republic of Nepal, is a landlocked country located in South Asia.
Nepal has an area of 147,181 square kilometers and a population of approximately 27 million. Nepal is the world's 93rd largest country by land mass and the 41st most populous country. It is located in the Himalayas and bordered to the north by the People's Republic of China, and to the south, east, and west by the Republic of India. Specifically, the Indian states of Uttarakhand, Uttar Pradesh, Bihar, West Bengal, and Sikkim border Nepal, whereas across the Himalayas lies the Tibet Autonomous Region. Nepal is separated from Bangladesh by the narrow Indian Siliguri Corridor. Kathmandu is the nation's capital and largest metropolis.
The mountainous north of Nepal has eight of the world's ten tallest mountains, including the highest point on Earth, Mount Everest, called Sagarmatha in the Nepali language. More than 240 peaks over 20,000 ft (6,096 m) above sea level are located in Nepal. The southern Terai region is fertile and humid. Lumbini, the birthplace of Lord Gautama Buddha, is located in this region. Lumbini is one of the holiest places of the Buddhist religion; it contains important evidence about the nature of Buddhist pilgrimages dating from as early as the 3rd century BCE.
Hinduism is practiced by about 81.3% of Nepalis, making it the country with the highest percentage of Hindus. Buddhism is linked historically with Nepal and is practiced by 9%, Islam by 4.4%, Kiratism 3.1%, Christianity 1.4%, and animism 0.4%. A large portion of the population, especially in the hill region, may identify themselves as both Hindu and Buddhist, which can be attributed to the syncretic nature of Hinduism and Buddhism in Nepal.
A monarchy throughout most of its history, Nepal was ruled by the Shah dynasty of kings from 1768, when Prithvi Narayan Shah unified its many small kingdoms until 2008. A decade-long Civil War involving the Communist Party of Nepal and several weeks of mass protests by all major political parties led to the 12-point agreement of 22 November 2005. The ensuing elections for the1st Nepalese Constituent Assembly on 28 May 2008 overwhelmingly favored the abolition of the monarchy and the establishment of a federal multiparty representative democratic republic.
Nepal remains isolated from the world's major land, air and sea transport routes although, within the country, aviation is in a better state, with 47 airports, 11 of them with paved runways; flights are frequent and support a sizable traffic. The hilly and mountainous terrain in the northern two-thirds of the country has made the building of roads and other infrastructure difficult and expensive. In 2007 there were just over 10,142 km (6,302 mi) of paved roads, and 7,140 km (4,437 mi) of unpaved road and one 59 km (37 mi) railway line in the south.[96] There is a single reliable road route from India to the Kathmandu Valley. More than one-third of its people live at least a two hours walk from the nearest all-season road; 15 out of 75 district headquarters are not connected by road. In addition, some 60% of road network and most rural roads are not operable during the rainy season.[97] The only practical seaport of entry for goods bound for Kathmandu is Calcutta in India. Internally, the poor state of development of the road system makes access to markets, schools, and health clinics a challenge.

Turn Pad: The RWY ends in a turn pad in both thresholds, and it is the only way for aircrafts to turn around as the parallel taxiway doesn’t reach both ends.o:.o RWY strip/RESA The RWY has a strip of 3140 x 150 Sq. m.Only northern part of the RWY has RESA. Currently it is only 90 m long from the end of the strip (as opposed to the ICAO recommended RESA length of 240 m), due to the land falling away steeply.o CWY RWY has CWY in both ends: 02 (245 x 150 m) and 20 (150 x 150 m)TaxiwayThe airfield has a parallel taxiway, but it doesn’t reach both RWY ends. Furthermore, thereare five exit taxiways (TWY1, TWY2, TWY3, TWY4 and TWY5, starting from THR20) whichlink the RWY and the TWY. They are 23 m wide and made of bituminous surface.Distance between RWY and TWY (109 m) is not enough to comply with ICAO standards,and is less than the required for any of the passenger jet aircraft operating in the airport.In the airfield there is also a decommissioned cross runway, which is being used now as ataxiway to reach the hangars.ApronThere are two civil aprons in the airport: one for domestic traffic and other for internationaloperations. Both of them are served like remote aprons, to which passengers reach by bus.The international one is located in front of the international terminal building and has 9
Technical Proposal
aircraft parking positions.The domestic apron is further from the domestic terminal and is located near THR20. It has enough space to house 25 aircrafts. There is also a military and maintenance apron, apart from the previously commented, and an helicopter apron located at the end of decommissioned cross runway.The helicopter landing area is located east of the runway opposite to TWY2 and TWY3.According to AIP, apron surface is made of cement concrete.AIRPORT ACTIVITIES SUBSYSTEMNavigation and landing aidsThe airport has four radio aids: NDB (KAM), VOR/DME (KTM) and two locators, Nalinchowk(LNC) and Thecho (LTH).There is an Approach Lighting System Cat-1 of high intensity on extended center line up to a distance of 870m for Runway- 02. Precision Approach Path Indicator (PAPI) System has been provided at both ends of the runway. The airport has a Meteorological office to provide Meteorological Report (METAR) data to the Control Tower ( TWR), Area Control Centre ( ACC ) and Approach Control units of Air Traffic Services. Meteorological Services are available during airport operation hours. Aerodrome, Aircraft Parking (Int. and Domestic), Aerodrome Ground Movement, Slope –Longitudinal Profile, Aerodrome Obstacle, Visual Aerodrome Traffic, Standard Departure, Standard Terminal Arrival Route, Instrumental Approach, TIA Controlled Airspace, Kathmandu Terminal Area, IFR Holdings, VFR Holdings, Mountain Flight Route Charts are available in the AIP document.Markings and lightingCentre lines are marked in RWY and TWY. Furthermore, RWY has Designation, THR, TDZ and edge marks. TWY has holding positions at all RWY/TWY iqqntersections marked. In the apron taxiing guidance signs at all intersections with TWY and RWY and at all holding positions, guide lines and nose-in guidance at aircrafts stands are marked. There are also stop bars, where appropriate.According to the AIP there are RWY end, THR and edge lights and TWY edge lights.Rescue and Fire Fighting Service According to the AIP the Category for firefighting is Category IX.Fuelling facilitiesJet A1 is available during operation hours. It is provided by Nepal Oil Corporation. There are six trucks, 1, 20,000 Liters, 1000 Liters/min.Passenger facilities: Terminal building and car parkingThe airport has three terminal buildings: domestic, international and VVIP.The Domestic terminal is located the nearest THR20. Only passengers can enter the building, as there is a policeman controlling it. There is a security control with two metal detectors and two X-Ray machines (men and women) and once it is crossed, there is a hall in which companies have their own counters for passengers to do the check-in. Then the passengers pass another security control to access the boarding hall, where two boarding gates can be found, apart from a restaurant and some other facilities. Boarding gates end directly in the apron, where buses take the passengers to the domestic apron and their corresponding aircraft. There is not arrival lounge in this terminal, but passengers are conducted directly to a covered shed outside the building where baggage claim is located.The international terminal is located in front of the international apron, lightly nearer to THR20than the domestic terminal. It has two entrance halls and airlines counters are distributed between both of them. In this case counters are flexible, not property of each company. Before entering this lounge, passengers must pass a security control in which their baggage is controlled (once it is checked in, not all the luggage is controlled). Then passengers go upstairs to the immigration control, where some passport controls are sited, and pass a security control to enter the boarding area. There are five international boarding gates, which access directly the apron.In the same way, arrival passengers enter the building by foot and reach the passport control, where Visa must be obtained. Once they have passed the immigration control they go downstairs to the baggage claim lounge, where there are three baggage belts. The meters and greeters waiting area is located outside the terminal building, in front of the gate for passengers to leave the building.VVIP terminal building is located just in front of the domestic apron.
Technical Proposal
There is a parking for vehicles in front of the international terminal building and a remote car park for the domestic terminal, so passengers have to walk under covered walkways to the terminal.Handling facilities/HangarThere are many hangars in the airport. At the end of the decommissioned cross runway there are two of them, property of Buddha Air and Yeti Airlines. Between the domestic and the international aprons there are two more hangars: a military one and a NAC (Nepal Airlines Company) maintenance hangar.Cargo handlingThe Cargo Handling is being done by the Airlines.
Operating capacity and obstaclesDue to both weather and very high and hazardous terrain around the airport, all IFR traffic lands from the south and takes off towards the south. Normally from July/August to November/December, cases of bird concentration and bird strikes at or in the vicinity of the aerodrome have been reported now and then. In other months stray birds may be encountered occasionally. Lots of measures have been adopted to control these birds concentrations, including driving them through guards and security personnel. According to the AIP there are 33 obstacles, which can be consulted in the AIP.

Technical Approach
Our first objective will be to make a realistic review of existing air traffic data and forecast them as required for the purpose of design of the facilities and review the master plan of the airport. It will be phased in such a manner, so as to meet the current and future operational, passenger and cargo demands. The master plan will further emphasize on the infrastructure that will promote and facilitate business and trade growth.
Similar approach shall be followed for identifying introduction of non-aeronautical facilities, which will provide services to the business community in connection with their trade. Nevertheless, emphasis will be made on safe and smooth terminal operations and user friendliness.
The New International Terminal Building and reconfiguration of the existing Terminal building will be made environmentally friendly and acceptable to the community by proper blending with the local environment and Architecture. It will also act as a catalyst for economic development in the neighborhood as it generates employment opportunities.
The Consultants will collect all the relevant information available with the CAAN, other trade and industrial bodies and analyze for their impact on passenger and cargo traffic. Any gaps shall be determined and further data collected for comprehensive analysis. A survey team for the same shall be identified and a suitable draft format devised for the collection of data.
4.4 General Approach
The general approach of the Consultants to undertake the service is to provide multi-disciplinary expertise each with an element of excellence, as role of the each discipline is crucial for the success of the endeavor. The Consultant’s dedicated team proposed for the assignment has been drawn from a pool of several eminent engineers and professionals with extensive experience in the field of airport master planning, architectural planning, airport engineering, airport logistics, airport design, navigational aids, runway lighting, E&M services, financial & economic planning, regulatory and operational aspects and environmental / social studies. The team will ensure:
The closest possible liaison between the Consultant’s team and CAAN,
That local conditions, regulations and traditions etc., are fully respected, and
To provide high quality services for successful implementation of the project within the budgeted cost.
The Consultant’s approach for carrying out the services is based on their extensive experience of successful completion of similar projects. For successful and efficient rendering of services, the Consultants proposes to take a sound engineering / professional approach based on clear understanding of the project, planning and systems approach. The Consultants shall give special emphasis to maintain the quality of services to be provided.
4.5 Quality Assurance Plan
Intercontinental Consultants and Technocrats Pvt. Ltd. is an ISO 9001:2008 certified firm with commitment to deliver a quality product. The Quality Assurance (QA) system will be based on the premise that at least two independent, responsible and qualified professionals agree on the correctness of each work output before it is delivered or used as input for another task.
Technical Proposal
This will ensure that the final documents and design efforts in the Detailed Project Report are of high quality.
Equally important is the level of interaction between the Consultants and the CAAN During the project preparation stage, the Consultants will interact frequently with the CAAN and hold joint reviews on various technical aspects so as to ensure high quality work covering all tasks under the scope of work.
For preparation of the project, following elements are considered essential to maintain quality:
The QA system will be developed to meet the specific requirements of the project depending upon the type of the facility, design criteria, design life and the acceptable level of quality.
Document verification, file supervision and quality control procedures on various surveys and site investigations.
Selection of quality materials and design techniques.
Development of design standards, technical specifications and acceptance criteria.
Design verification - At every appropriate stage of design preparation, design verification will be performed to ensure that the final product, while conforming to all relevant laid-down standards and specifications, is cost effective and can be easily implemented at site. The design verification will include tasks such as performing alternate calculations, adoption of proven design methods / concepts etc. The QA system will be designed to achieve, sustain and improve the quality of service, and to assure the CAAN that internal controls are effective and adequate and fully conform to the requirements of the codes and technical specifications. Quality Assurance will be an integral part of every work function and will be essentially the system of planning, organizing and controlling “human skills” to assure their compliance. Accordingly, each of the significant engineering process and sequence of steps that are to be followed by the survey / investigation and design teams will be clearly spelt out. Step-by-step procedures defining clearly the responsibilities of each process, will be evolved for various surveys, investigations and designs like topographic surveys, material and geo-technical investigations, study of water and power supply, drainage and sewerage system, inventory and condition surveys for existing pavements, design of pavement, Environmental and Social Mitigation Management Program (ESMP), etc.
4.6 Methodology Framework
