Station Design

4.1 Design Standard4.1.1 Station Design: Overview

The design of stations shall be consistent with MRT train operation. Design considerations include the promptness to connect with both present and future mass transportation system, convenient and safe access to station for passengers, international standard safety system in case of emergency. In addition, opportunity and possibility for community development and reduction of negative impact to community are carefully considered in station design.

Purposes

1) To design stations which are consistent to the surroundings, in accordance with other MRT systems which are connected to Khae Rai - Minburi route. Station design shall also promote the maximum convenience of passengers.

2) To design stations which are in accordance with train operation system, low-cost maintenance and efficient.

3) To design stations which are enable to connect with other facilities and surrounded areas.

4) To fully facilitate and serve all type of passengers, including those who are disabled.4.1.2 Design Standard

The station design elements comply with Thai building code and selected international standard (NFPA 130, NFPA 101) appropriate to each element shall be selected.

4.2Concept for Station Design and Functional Space Arrangement4.2.1Main ConceptsMain concepts in architectural design of stations are as followed:

1) Stations shall have a light and sparse-architectural look.

2) Columns to support platform roof shall not obstruct passengers circulation on platform. Platform, therefore, shall have a wider space. Roof of platform shall be designed as to protect passengers from rains. Rainwater shall be appropriately flow to designated points.

3) Station components shall be designed in accordance with their functions. Aesthetics and cost efficiency shall also be considered.

4) Materials used shall be durable, easy to maintain, aesthetical with reasonable cost.

5) Energy saving in both Passive and Active Cooling. Stations shall be well insulated and well ventilated. 6) Functional space arrangement and interior decoration concepts shall focus on the avoidance of passengers confusion. Elevated stations shall be natural ventilated and provide good visibility. Natural lights inside stations shall be suitable for passengers. Interior architecture shall be focused on simplicity. Safety, convenience and color of materials shall be carefully selected.

7) Environmental impact shall be considered.

8) Stations design shall be developed to achieve simplicity in style in order to consistent with function and budget. In addition, stations design shall reflect Thai architecture.

9) Stations design shall response to directions of passengers movement both inside and outside station. 4.2.2 Concept for Functional Areas Design 4.2.2.1 Functional Areas Design Concept

Main concepts in designing functional areas are:

1) Rooms and station components shall be carefully organized. Passengers area shall be separated from staff area and station equipment room. Zoning of station shall be clear according to function.

2) Stairs to connect concourse and platforms, which are a pair of stairs, escalator, stairs for disabled, shall be located to suitably response to the six-car train. Stairs and escalator shall conveniently serve passengers in both Normal Operation Movement and Emergency Evacuation Movement.

3) Functional areas arrangement shall be in accordance with train operating system and building equipment system.

4) In order to achieve cost efficiency, station shall be designed to suit the number of passengers in each station.

5) To renovate, expand footpaths which are close to stations in order to provide convenient entry and exit of stations, including walkway.Table 4.2-2 Functional Area

Elevated stations, which have 2-3 levels, consist of two main areas: Platform and Concourse. The layout of typical station shall be as followed. Chapter 4
