Synopsis
The assignment involves conducting a feasibility study and designing the conversion of 40 existing steel bridges to reinforced concrete (RCC) bridges, including the construction of new bridges. The project is supported by DFID and involves the replacement of Acrow/NATO steel bridges with Canadian Steel Bridges provided by the Pakistan Army. The aim is to improve the communication network in the Swat District of Khyber Pakhtunkhwa, Pakistan, by providing all-weather routes.
Narrative Description of Project
The Communication & Works Department of District Swat in Pakistan has contracted SES to carry out the assignment to convert 40 existing steel bridges to reinforced concrete (RCC) bridges, as well as the construction of new bridges in the Swat District of Khyber Pakhtunkhwa, Pakistan. The project is being undertaken with the support of DFID (Department for International Development) and involves replacing the current Acrow/NATO steel bridges with Canadian Steel Bridges provided by the Pakistan Army. The primary objective of this endeavor is to improve the communication network in the region by establishing all-weather routes.
The project’s narrative emphasizes the significance of the initiative, which aims to enhance the communication network in the Swat District by creating robust and resilient infrastructure. The conversion of the existing steel bridges to RCC bridges will ensure greater durability, improved load-bearing capacity, and enhanced safety for vehicles and pedestrians. Additionally, the construction of new bridges will contribute to expanding the connectivity within the district and facilitate smoother transportation even during adverse weather conditions.
