TLIP is situated at an intermediate position along the highway linking the center of Hanoi and Noi Bai International Airport. Its ideal location offers easy access for transportation and commuting.

In 1996, Hanoi was given the approval from the Prime Minister on "General Amendments of Master Plan for Development of Hanoi by the year 2020" which endorsed the development of North Thang Long - Van Tri area for the prime center of new Hanoi City. In accordance with this Master Plan, construction of infrastructure such as an interchange on the highway, new industrial roads, water supply, wastewater treatment and electric supply systems for the surrounding area of TLIP will be implemented soon with financial support from the Government of Japan. This is called the "Hanoi Infrastructure Development Plan".

The development and salable area of Phase 1 is shown below.

TLIP offers various sizes and shapes of the plot in order to fulfill tenants' requirement.

TLIP is designed to be Free From Flood. After filling, the elevation of the site is 8.3 m (27 feet) at the lowest and 10.5 m (35 feet) at the highest above sea level, and it keeps higher elevation by 2 - 3 m (7 – 10 feet) than its surrounding area.

The character of the ground soil is sand mixed with silt clay and firm and sound enough for construction of various type of factories on it. The result of geo-technical survey shows that pilling is not required for the construction of an average type of up to 2-story factory. However, the soil condition is different from point to point, and, therefore, we recommend that tenants should conduct geo-technical tests in their plots before starting construction of factories.

Internal roads are classified into two types as shown below. The road system in TLIP is designed to cope with the increase of traffic volume in the future and traffic characteristic of Vietnam.

• Main Road
  Width of the road ranging between 37 m (121 feet) and 42 m (138 feet).
  Asphalt pavement road with 6 traffic lanes for 2 sides.
  Street light poles are aligning in parallel with 40 m (131 feet) interval at both sides of road.
  3 m - wide (10 feet) median and sidewalk at both sides.
  This Main Road, which is as high as the Hanoi – Noi Bai Highway, meets Level C in Japanese Traffic Classification.
  
• Secondary Road
  Width of the road ranging between 26 m (85 feet) and 27 m (89 feet).
  Asphalt pavement road with 2 traffic lanes for 2 sides.
  Street light poles are aligning in zigzag with 45 m (148 feet) interval at both sides of road.
  Sidewalk at both sides.

TLIP provides tenants with purified water for industrial use through the distribution pipe network made of ductile iron.

Wastewater from factories is collected through the underground piping network and treated at the in-house Wastewater Treatment Plant before discharging to the drainage canal running along the southern boundary of the park through the effluent pipeline. At the Wastewater Treatment Plant, Biochemical Oxygen Demand (BOD₅), Chemical Oxygen Demand (COD_CR) and Suspended Solid (SS) are treated to meet the Vietnamese Environmental Regulation.

The drainage system is composed of Box Culvert and Covered Open Ditch network and retention ponds. Since the flow capacity of drainage ditches and related structure are calculated with the consideration of recorded data, TLIP can be kept Free From Flood even in case of heavy storm and typhoon in the rainy season.

The internal telecommunication network is underground, with consideration of appearance and safety. 400 lines are available for the Phase 1 (121 ha) and Hanoi Post and Telecom Company will supply more lines for the future in capacity and quality with optical fiber to accommodate high speed data communication, ISDN and so on.

TLIP has its own on-site sub-station with capacity of 40MVA x 2 which receives the extra high voltage electricity directly from the national network, through 2 circuits. Tapping from the new 110kV transmission line from the Hoa Binh Hydraulic Power Plant via Chem sub-station as one source; and from Pha Lai Thermal Power Plant via Dong Anh sub-station as the second source can ensure the stability of power supply to tenants with less fluctuation of voltage. Transformer and Switch-gear in Chem sub-station was renewed and expanded to 250MVA x 2 in 1999 with financial support from the World Bank.

The internal power distribution system is also underground and is a double loop system for making sure the power supply to the tenant is uninterrupted and reliable enough for manufacturing operation. Tenants receive electricity from ring main units which are installed right at every plots.

The design, construction management and construction of TLIP was undertaken by the internationally reputed Japanese engineering company and general contractor.
