E-procurement implementation in other parts of the world has brought benefits such as efficiency, cost reduction, reduced procurement process, minimised corruption, enhanced compliance and standardisation of procurement. Though the Public Procurement Authority has made many strides in the adoption of e-procurement in the Ghanaian Public Sector, the pace for the implementation and adoption is still very slow. Thus, the aim of this study is to evaluate the critical factors for the implementation of e-procurement in Ghana. With the knowledge of these critical factors for e-procurement implementation a survey was conducted involving 60 procurement professionals. The mean score ranking test was then used to determine the factors that were significant to the implementation of e-procurement. The results revealed that availability of internet, power stability, capacity enhancement of procurement officers, availability of infrastructure were important critical factors when it comes to implementation of e-procurement while the mandatory use of e-procurement, technical interoperability budgetary control among others were of less importance. This study therefore evaluates the critical factors for e-procurement implementation in public sectors. The implication is that the finding offers useful factors that will guide the stakeholders and policy makers in e-procurement implementation. It provides practitioners with better understanding of e-procurement environment.

The construction industry in Ghana is becoming efficient in the area of cost and achieving advance technologies. The effective management of cost enables clients, developers, and facilitators to achieve value for money. Concrete is a major component in every construction project. The use of precast concrete technology has been embraced by the construction industry in Ghana. This study seeks to analyze cost estimating of the structural frame (column and slab) by considering cast-in-place and precast concrete slabs and columns, respectively. Relative importance and Kendall’s concordance agreement were used to determine the rankings and agreement of advantages of using precast concrete. The study established that precast concrete slabs were on average 23.22% cheaper than the cast-in-place concrete elements and precast columns were averagely 21.4% less than cast-in-place concrete columns. The study established that professionals prefer the use of precast concrete products because of the life cycle cost.
