Analysis 1 - Construction of Precast Vs. Cast in Place Concrete

Suggests the use precast concrete, instead of the intended cast-in place concrete. Since cast-in place concrete can take time for the concrete to set and place, precast could be a faster and cheaper alternative. This will show if this alternative method of construction has any potential to accelerate the schedule. A structural and mechanical breadth will encompass this analysis due to the change in structural and mechanical loads, therefore further research must be made to see if there any impacts in structural and mechanical performances of the building.

Analysis 2 - SIPS Implementation for Precast Vs. Cast in Place

Explores the use of Short Interval Production Schedule (SIPS) to both of the concrete placing methods; the suggested precast and the originally intended cast in place. Due to the repetitive nature of the structure, this created a great opportunity to implement SIPS. This analysis will help investigate the impact of crews and the tasks to increase the efficiency, productivity and quality of work.

Analysis 3 - Comparison of Construction Practices between US & Qatar

Focuses on the comparison of construction practices between the US and Qatar. This will help gain some knowledge as to where the project is losing time and money in comparison if it were built in the US. Research on Labor and Material will be critical to understand the main differences that impact construction in both countries. This could help provide other construction techniques into the Mansoura Development that could save money and time from the overall schedule.

Analysis 4 - Field Labor Management & Alteration

Explores schedule and labor re-adjustment in order to by-pass the halt of construction during the hot summer months. This will be regarded as the main topic of research as it is seen as the major potential negative impact to the project by creating a delay in the overall schedule. This research will help find a solution to overcome this problem.

Breadth 1 (Structural): This breadth will analyze the structural load difference of having precast concrete over cast-in place concrete. As mentioned in the analyses, the current structure is made entirely of cast-in place concrete, tehrefore i will experiment with precast and note the structural load differences. Since the thickness of the concrete would decrease, this should impact the loading of the entire structure on the foundations. This in turn could change the specifications of the foundations, which could help experiment with a cheaper form or alternate foundation system that would help save money, and be quicker to produce. Proper bearing capacity and building loads will need to be considered with the new system. However there is a structural concern with tying the precast concrete to the structure, which should be analyzed and further reviewed.

Breadth 2 (Mechanical): This breadth will target the mechanical installation and calculation of the difference in heating and cooling loads and note the disparity of energy efficiency between both concrete-placing methods. This will help in comparing both methods and determine if precast is an acceptable alternative. A basic resizing of equipment will be performed if required, and those costs will be included in the analysis. In addition, if any significant changes in the building’s mechanical performance are found, this analysis could help determine whether the mechanical system in use is appropriate for this change.
