City
Amman, Jordan
Cost
USD 350 Million
Year
2011
Client
Abdali Investment & Development PSC
Area
237,000 m2 built-up - 26,000 m2 land
Project Brief
<p>Scope: Multi-level interchange serving as western gateway to Abdali and Amman New Downtown. 5 bridges (100-200m length, 10-18m width), 2 tunnels (100-160m), 1 at-grade roundabout, 3 technical underground areas. Complete storm drainage, electrical services, and utilities relocations/reinstatement.<br>Challenge: Achieve dual Greater Amman Municipality objectives: permanent solution for traffic congestion at vital location and direct access to all directions without conflict. Find optimal solution providing accessibility to all probable destinations with minimum land expropriation while ensuring additional vertical clearances required by client. Navigate complex three-dimensional design in constrained urban context at gateway to major development.<br>Approach: Upgraded existing at-grade intersection to sophisticated multi-level interchange. Five bridges and two tunnels enable complete grade-separated movement to all destinations - eliminating conflicts that created congestion. At-grade roundabout maintains local circulation. Three technical underground areas consolidate utilities and systems. Storm drainage and electrical services designed throughout. Utilities relocated and reinstated as needed. Solution optimized to balance complete accessibility, minimal land expropriation, and client vertical clearance requirements - complex three-dimensional puzzle resolved through iterative design.<br>Status: Completed</p>

Our Response
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.
Our Response
Laceco responded to the above objectives by:
Proposing to upgrade the existing at-grade intersection to a multi-level interchange consisting of five bridges (length 100m to 200m and width 10m to 18m), two tunnels (100m to 160m), 1 at-grade roundabout and three technical underground areas.
Designing required storm drainage, electrical services and utilities relocations re-instatement as needed.
Interesting facts:
Finding the optimal solution that provides accessibility to all probable destinations with minimum land expropriation while ensuring the additional vertical clearances required by the client.
