This article is about technical requirements of Layout and Spacing of Buildings and Substations as per international codes and standards.
Layout and Spacing of Buildings and Substations
Buildings Outside Process Units
Spacing between buildings other than process unit structures, such as shops, laboratories, administration shall be based on the type of construction and shall conform to the requirements of applicable NFPA codes, local fire codes, and the specification of Tables 1-A and 2-A this Specification whichever is more stringent.
Spacing recommendations to main pipeways are based on all welded pipe in the pipeway. Sections of the pipeway containing numerous flanges, vents, drains, or other release sources should be treated as process area pipeways in regard to spacing. Consideration shall be given to providing protective covers or deflectors over gasketed and packed joints in piping containing acids, caustic and other hazardous chemicals where such lines are adjacent to walkways or work areas.
No piping containing oil, flammable liquids, gases, toxic materials or high pressure steam shall be installed in control rooms, washrooms or in similar locations. There shall be no floor drains in control room or adjacent laboratories. Piping, except steam heating piping, shall not enter switch rooms or be under the floor.
Layout and Spacing of Buildings and Substations
The layout and spacing of buildings and substations in a facility are crucial for ensuring safe and efficient operations. Here are some key factors to consider when designing the layout and spacing:
- Safety: The first priority in the layout and spacing of buildings and substations is to ensure the safety of personnel and equipment. Buildings should be located away from potential hazards such as pipelines, storage tanks, and process equipment. Substations should also be designed to minimize the risk of electrical hazards, with appropriate grounding and clearances.
- Accessibility: Buildings and substations should be located in easily accessible areas to allow for efficient maintenance and repair. Adequate space should be provided for personnel and equipment to move around the buildings and substations, including access to emergency exits and fire suppression equipment.
- Space utilization: Space utilization is an important factor in the layout and spacing of buildings and substations. Buildings should be arranged to make the most efficient use of available space, while allowing for future expansion. Substations should be designed to minimize the amount of space required for electrical equipment, while still providing adequate clearance for safe operation.
- Aesthetics: The layout and spacing of buildings and substations can have a significant impact on the appearance of a facility. Careful consideration should be given to the aesthetic impact of the design, including the use of landscaping and other features to enhance the appearance of the facility.
- Regulatory requirements: Building and substation layouts must comply with local regulations and codes, including zoning requirements and setbacks. It is important to work with local authorities to ensure compliance with all applicable regulations.
