The project involves design and construction of 9.5 kilometres long and 3.7 meters pre-cast segment lined inside diameter, storm water conveyance tunnel. The project also includes 24 deep access shafts and their adit-tunnel connections for Qatar Public Work Authority (ASHGHAL). My involvement for the tunnelling work includes, review of the original program base line, monitoring all the phases of the construction including tracking of original additional geotechnical investigation performed by the General Contractor, monitor the design and it’s review, monitor all required permitting (from local and municipal authorities) for construction, site investigation, transportation, environmental activities (material management, dewatering discharge to the sea or into evaporation lagoons etc.). In addition to the monitoring previously mentioned, my responsibility includes tracking of procurement including tunnel boring machines till dismantling, precast segments, micro tunnel and open trench pipes, drop shafts etc.; tracking of construction phase including tunnel boring works which requires maintaining records of supply and consumption of tunnel precast segments and rings, forecasting of the TBM breakthrough, tracking records and histogram of precast segments of the main tunnel ring and Invert production and consumption compared with the approved baseline data, tracking and maintaining progress curves of access shafts excavation, dewatering, permanent lining and adit works compared with approved baseline program data. I also monitor and help analysing the site instruction and variation order supporting the contract management team to assess potential claims for time impact assessment affecting the final completion of the project. Another aspect of my responsibilities includes utilizing latest version of Primavera P6 software to produce and monitor a resource loaded schedule of works to ensure that the project is completed on time and within budget. I report directly to the to the Project Manager and the Senior resident Engineer on all project planning and monitoring related issues, I am responsible to track the review and approval of the submittal work program by contractors. I am also responsible for monitoring the work progress during the construction analyzing and comparing the approved baseline program of works with actual progress reporting to Project Manager. I am responsible for producing weekly and monthly look-ahead schedule, reports about the status of construction progress and implementation of Earned Value Management System, to advise any potential delays in the project completion and to perform time impact analysis. I work closely with the Project Manager in finalizing delay claims using impacted as planned and as-built methods along with window analysis, analysing concurrent delays if any.
