Doha's city center regeneration covers a 35-hectare site and involves creating a modern and revitalized heart for the capital, rooted in Arabic and Islamic traditions. The objective is to create an urbane and sophisticated city core which will be attractive to the Qatari citizens. This is to be achieved through physical transformation of the urban form, landscape, land use and infrastructure.The masterplan has emerged from an in-depth understanding of the existing urban morphology of inner Doha, based on historical aerial photographs. AECOM's design response is to superimpose the orthogonal street grid onto an informal lattice. The orthogonal grid accommodates modern day vehicular movement and the finer-grain walkways create incidental and intricate spaces which reflect the Arab/Islamic vernacular. Implicit within this morphological proposal is an integrated microclimatic and transport strategy. The urban grain has been oriented to capture the north-westerly sea breeze and to reduce the ambient temperature by creating shades in narrow streets. Another key urban design objective is to re-establish the relationship between the site and the corniche through the rejuvenated Souk Waqif, where urban life is weaved back into the city fabric along the old Wadi route. The intention is to reconnect the city center with the waterfront which have been severed by a wide highway corridor and insensitive development.AECOM produced a conceptual masterplan followed by a detailed masterplan and design codes, and has recently been commissioned to act in an important masterplan oversight role, ensuring that the principles of the masterplan are taken forward in its implementation and design codes are adhered to.
