July 20, 2024On an area of 230 hectares (2.3km2) this mega site is located in Jubail Industrial City, this project is integrative city contains of multi use buildings (administrative - healthcare - residential - dedicated services - public services), these buildings are connected by mega roads network starts with surround road, internal intersections, major roads and ends with local roads & parking lots. Figure (1) and (2)
External lighting infrastructure design in the city, includes:
- Major Roads
- Local Roads
- Surrounded Road
- Intersection
- Pedestrian Lanes
- Landscape
In order to achieve theses, the scope of work will cover:
- Power Cables Network: voltage drop calculations and cables route from main power source to all connected loads.
- Lighting Design: illuminations levels in all roads and spaces, technical specifications for luminaries as well
The following standards have been followed in design activities:
CIE : The International Commission on Illumination Figure (3)
SEC DPS : Saudi Electricity Distribution Panning Standard Figure (4)
Infrastructure works had been divided to 9 areas with similar spaces to boost design efficiency and constructability inline with other works , to better understand division method see Figure (5)
Lighting:
Fixture types :
Four types of fixtures have been used in addition to one more for landscape areas as in Figure (6)
Lighting Calculations :
Lighting calculation shave been conducted using DIALux Software for all fixture types. Browse images in Figure (7)
Electricity :
الأحمال :
All lighting fixtures are LED with amount of 1533 peaces and total load of 112.7 Kilo.Volt Ampere (including power factor). Figure (8)
الكيابل :
Number of power cables used in this project = 80 copper cable with a total lengths equals to approximately 57000 meters (57 km) , average voltage drop for all cables = 1.18% Volt
