The Saudi National Guard project aimed to accommodate 57,000 officers and soldiers with all necessary services and utilities. The master plan respects site topography and sustainable practices while preserving existing infrastructure and optimizing integration of new services. It also ensures proper servicing of all future public and private developments in the area, excluding residential zones, to support the overall functionality of the project.
Roads and infrastructure design
Laceco responded to the above objectives by:
Designing a consistent urban framework that nevertheless provided a diversity in the individual architectural character of buildings.
Curating a seamless pedestrian experience in a site that had a challenging topography and was exposed to dominant winds.
Anchoring the site along three platforms linked to each other by a continuous game of terraces, stairs, suspended bridges and esplanades that gently slope down the length of the development.
Conducting value engineering and cost optimization studies to preserve economic viability of the development.
Laceco responded to these objectives by the following: Performing a traffic impact study including modeling and simulation for intersections and gates to ensure high level of service for all roads and functions, Proposing a 200‚Äâkm roads network that balances between capacity, accessibility and privacy, tying with the existing surrounding roads by five gates, and incorporating collector/secondary/tertiary roads, and spine roads, Opting for a combined domestic and firefighting network with centralized water storage of 20,000‚Äâm3, and a central automatic irrigation system fed from the treated sewage effluent, Designing sanitary/storm sewer collection networks including lift stations where needed, Designing medium/low voltage distribution networks, including the related MV/LV package substations, high voltage cable reservation, street and landscape lighting, and telecom duct banks, Proposing a sewage treatment plant (20,000‚Äâm3/day-extendible to 30,000‚Äâm3/day), Implementing two 90,000‚Äâm3 evaporation ponds to store storm water generated by the project.
