Purpose
The non-achievement of projects of best value remains a perennial problem within the construction industry. This paper aims to identify the latent shortcomings affecting the achievement of value for money (VfM) within the Ghanaian construction industry.
Design/methodology/approach
From a comprehensive literature review and pilot survey, 18 variables responsible for the non-achievement of VfM were identified. Through purposive and snowballing sampling techniques, a questionnaire was administered to the target professionals. Factor analysis was used to establish the latent shortcomings underlying the same dimensions of VfM achievement in the Ghanaian construction industry.
Findings
A total of six components were identified and explained as external factors; institutional culture and policy constraints; technical and decision-making factors; human-related factors and accountability and transparency constraints. The relative importance index was used in analysing the strategies to addressing the shortcomings.
Social implications
The prevalent situation of poorly delivered projects and the continuous campaign for VfM necessitated the need for a study into explaining the latent shortcomings in achieving VfM within the Ghanaian construction industry. It is recommended that governments give VfM in public projects serious attention. This would help to reduce the overall cost of construction projects without compromising quality. When VfM is taken seriously, governments can save more money and undertake more projects as well as gain public acceptance in terms of transparency and accountability.
Originality/value
This study has set the pace for further research in the VfM analysis by identifying the latent shortcoming, which other developing countries can emulate.
Purpose
Tender price remains an imperative parameter for clients in deciding whether to invest in a construction project, and it serves as a basis for tender price index (TPI) manipulations. This paper aims to examine the factors affecting tender price in the construction industry.
Design/methodology/approach
Based on the literature review, nine independent constructs and one dependent construct relating to tender pricing were identified. A structured questionnaire survey was conducted among quantity surveyors in Ghana. Partial least squares structural equation modelling (PLS-SEM) examined the influences of various constructs on tender price development (TPD) and the relationships among TPD and TPI.
Findings
Results showed that cultural attributes, client attributes, contractor attributes; contract procedures and procurement methods; consultant and design team; external factors and market conditions; project attributes; sustainable and technological attributes; and TPI have a positive influence on tender price, whereas fraudulent attributes exert a negative influence.
Practical implications
The findings offer construction professionals broader understanding of factors that affect tender pricing. The results may be used in professional decision-making in the pricing of construction projects, as they offer clearer causal relations between how each construct will influence pricing.
Originality/value
This study adds to the body of construction pricing knowledge by establishing the relationships and degree of influences of various factors on tender price. These findings provide a valuable reference for practitioners.
Waste associated with building design is one of the causes of the high cost and slow progress of construction projects in Ghana. Proper management of waste at the design stage is therefore a fundamental step towards achieving speedy delivery of building projects at minimum cost. This paper seeks to examine the level of awareness of sources of waste and the application of waste reduction tools in the building design process by Ghanaian consultancy firms. Data on the design activities of the firms were collected by distributing questionnaires to consultants, while contractors and clients were interviewed. Involvement in various building design processes was also used to obtain data for the study. Results revealed a generally low recognition of sources of waste in the building design process and little awareness of waste reduction tools such as design structure matrix, batch size reduction and set-based design. It was also found that inadequate familiarity of the firms with lean thinking was among a number of limitations to the application of waste reduction tools in Ghana. This suggests that there is a need to improve the awareness of lean design management in both education and practice in Ghana.
