▣ Overview and Review Content
1) Overview
- The plot plan for the power plant should consider an effective arrangement of the power generation equipment area, auxiliary facilities, and various tanks.
- Plan for an optimal and environmentally friendly power plant layout that considers accessibility, cost-effectiveness, constructability, operability, maintainability, safety, comfort, and aesthetics.
2) Review Content
When planning the plot plan for the power plant, consider the following aspects to construct an economical power plant with excellent performance and reliable equipment:
① Optimal Layout Plan for Power Generation and Auxiliary Equipment Areas
- Optimize building size through systematic and functional arrangement of all equipment.
- Shorten construction period and improve constructability (minimize construction interference).
- Reduce construction and maintenance costs (shorten connection lengths for pipes, ducts, and cables).
- Ensure operability of equipment, stability of system, and access routes for maintenance and inspection.
- Introduce Value Engineering (VE) concepts in the arrangement of buildings and equipment to reduce costs.
- Exclude functional issues during system operation post-completion.
- Consider plans for subsequent unit expansions and efficient use of spare land.
② Plan for an Environmentally Friendly Power Plant Layout
- Plan a nature-friendly power plant considering the regional characteristics.
- Secure green space and maintain a pleasant environment in the spare land of the power plant.
- Allocate sports facilities in the expansion area if necessary.
▣ Current Status of Construction Site
1) Site Status
Describe the location, area, ground elevation, and geographical conditions of the power plant construction site. Include considerations for determining ground elevation and the usable area.
2) Site Status Map
Incorporate the site status map or survey of the planned construction site into the plot plan.
3) Access Road and Drainage Plan
Arrange the main and rear entrance access roads at convenient points of the power plant site, and plan the drainage comprehensively considering the site conditions.

▣ Detailed Considerations for Power Plant
1) Power Plant Plot Plan
- Divide into power generation and outdoor equipment areas, and establish a plan for the arrangement of equipment, buildings, and roads. Confirm the size of equipment and buildings and finalize functional aspects according to the design progress.
- Group equipment by system, process, and function, and simplify equipment and piping layout to optimize building size.
- Ensure the connectivity of buildings and equipment with sufficient space for maintenance, inspection, and access.
- Minimize construction interference during the power plant construction period (prevent project delays).
- Plan to avoid functional issues during system operation post-completion.
- Design the exterior of the power plant to be environmentally friendly if located near a tourist area or as requested by the client.
- Protect equipment from wind and salt damage and minimize heat loss by placing as much equipment as possible indoors in areas prone to high waves and strong winds (typhoons). Use steel structures resistant to strong winds and design to prevent noise from spreading outside.
- Simplify equipment layout as much as possible. Plan common facilities with sufficient capacity for future expansions and arrange them for easy sharing.
- Integrate and classify buildings by purpose and function, considering future equipment expansions and site use.
- Arrange equipment layout in a portable type (Copy Type) to facilitate design, construction, operation, and maintenance.
- Ensure effective space utilization and economical site layout by considering accessibility, constructability, operability, maintainability, safety, aesthetics, and surrounding area balance when arranging equipment. Place equipment adjacent to surrounding roads for easy access during construction.
2) Considerations by Aspect
- Safety conditions (internal/external plant safety measures)
- Design conditions
- Process requirements
- Construction conditions
- Operational conditions
- Transportation and preservation conditions

▣ Review of Site Layout Plan
Review the optimal layout plan considering the geographical and environmental conditions of the construction site.
[Layout Criteria]
- Place power generation facilities in areas with good ground conditions.
- Locate administrative buildings near the main entrance
- of the site.
- Position seawater intake points to minimize the intake of foreign substances by deep water intake.
- Place the main gate of the power plant at a point that is easily accessible from outside.
- Position the power duct considering the site and equipment layout characteristics alongside the road.
- Integrate steam turbines and boilers indoors as much as possible to facilitate emergency response.
- Reflect the characteristics of clean and coastal areas and establish a power plant image harmonious with the surrounding environment by arranging green spaces and sports facilities in spare land.
- Arrange chimneys considering the landscape, and design outdoor coal yards with dust prevention measures.
- Balance the entire site by positioning large power generation facilities centrally.
