Abstract: Construction industry fragmentation into nearly a million Small to Medium Sized Enterprises (SME) in the UK led to calls for the European procurement process to be more inclusive. The innovation and skills of these organisations was not being correctly utilized in Government contracts. The introduction of the new procurement directives Europe wide sought to solve this problem. However, the perspective of SME’s on issues such as self-declaration provisions, breaking contracts into lots, limits to the financial capacity required, and the effect on procurement if more SMEs tendered had not been fully researched. This paper’s findings show an increase in SME involvement as predicted, and that the other elements of the new regulations are appreciated but that organisations have concerns over the capacity of government departments to administer contracts in lots.

Abstract: The planning of a rail transit system is a complex process involving the determination of station locations and rail line alignments connecting the stations. There are many requirements and constraints to be considered in the planning process, with complex correlations and interactions, necessitating the application of optimization models in order to realize reliable and cost-effective rail transit systems. Although various optimization models have been developed to solve the rail transit system planning problem, most neglect the complex interactions between station locations and associated rail lines linking them station by treating them in separate optimization processes. This is in addition to focusing mainly on a single objective system requirement and thus resulting in suboptimal solutions. This paper addresses the limitations in the current approaches by developing an optimal planning methodology that treats the rail transit system and its influencing factors in a single integrat
