CONSTRUCTION QUALITY FOR A N EW START TRANSIT SYSTEM: THE CASE OF TREN URBANO By

As with many other large-scale infrastructure projects, the construction of a transit project is potentially vulnerable to quality failures, which can lead to completion delays and cost overruns. Especially with technologically advanced, new-start transit projects, a limitation or lack of skilled labor can exacerbate those risks. This thesis examines the case of Tren Urbano in San Juan, Puerto Rico, a rapid rail project currently being constructed in an area with limited on-island experience in the design, construction, operation or maintenance of such a technologically sophisticated transit system. The motivating question for this thesis is, does training matter for construction quality? The research findings of this thesis show that the multiple prime contractors operating under similar contractual arrangements and resource conditions in San Juan exhibit variations in the quality of construction. Research findings also reveal variations in the type of training programs established by the contractors. A limited conclusion is drawn that although training of inexperienced labor does not single-handedly insure high quality of construction, it nevertheless is important to the successful implementation o
