To alleviate the traffic congestion of the A.A city, it is vital and crucial to allocate underpass andrnoverpass transportation means for the expansion of roads and construction of supportive infrastructure.rnAlthough, the construction of high rise building are significantly increasing, especially by financial andrncommercial institutions as well as by other individual investors for hotel and real state purposes. Thosernbuildings require large parking area, stores and other facilities that can only be alleviated by constructingrnbasements. To construct basements and underground transportation means deep excavation is a must.rnDeep excavation is an important component of construction which relieves shortage of space and allowsrnusage of underground spaces for different structures. Thus, this thesis is prepared to study practice ofrndeep excavation in scientific way and to develop a better ways for execution of deep excavation in urbanrnareas.rnThe research was undertaken to assess the practices in planning, quality assurance services andrnexecution, identify challenges that need to be addressed and to recommend interventions in order tornimprove execution management of deep excavation in A.A. civil work projects. Accordingly, a literaturernreview was conducted on related topics, through which numerous variables challenge was identified. Inrnthe matter of fact, detailed analyses were accomplished with primary data collected throughrnquestionnaire, interviews and by physical observation of projects.rnThe response are found from different professional found in employers, consultants and contractors sidernand which are engaged on the three civil work construction projects (i.e. building, road & railway). Thernresponses are calculated by using a weight average technique of all groups as per each variable ranked.rnBased on the findings it is observed that, challenges as safety and health management, lack of recordingrnconstruction events, wrong calculation of earth pressure and lack of well qualified and experiencedrnprofessionals found to be the most common outstanding once. Failures encountered and observed fromrnrespondents are differential settlement, subsidence of ground, cracks on nearby structures and collapsernon adjacent structures including small injuries up to loss of lives of workers and also neighboringrncommunity living on adjacent have been recorded & investigated.rnRecommendations are forwarded by pointing out the responses & expectations from clients, consultantsrnand contractors. Those recommendations cultivate us to adopt quality assurance by implementingrnrecording and analyzing construction events with close supervision. During construction, monitoringrnexecution compliance by regulatory bodies and upgrading professionals experience through continuousrnprofessional development trainings are deemed as remedial measure to execute fatal and hazard freerndeep excavation in A.A.
