The problem of delays in the construction industry is a global phenomenon and the construction industry in Botswana is not an exception. The objectives of this study were to confirm the presence of significant delay in GCC projects; to identify and rank the perceived delay causes; and construct a Bromilow-type time-cost model for the council’s projects. The study made use of archival data and questionnaire survey soliciting the perceived causes and effects of delay from the clients, consultants, and contractors that are associated with GCC projects. Chi-square statistical method was employed to prove the presence of statistically significant delay in the council’s project. About 150 respondents drawn from three client organizations, five consulting firms and 23 construction contracting companies participated in the survey to rank the perceived causes of delay. The study identified 10 most important causes of delay from a list of twenty eight different causes and six different effects of delay. The ten most important causes are: contractor’s improper planning, contractor's poor site management, inadequate contractor experience, inadequate client's finance and payments for completed work, problems with subcontractors, shortage in material, labor supply, equipment availability and failure, lack of communication between parties, and mistakes during the construction stage. The six main effects of delay were: time overrun cost overrun, disputes, arbitration, litigation and total abandonment. In addition, archival data were used to establish the time-cost relationship of the council’s projects using Bromilow’s model. The derived relationship was given by Time = 1.18Cost0.361861. The adjusted R2 of the model was 0.817812 showing that the model had high predictability. It was concluded that the results of this study can be of immense assistance to the stakeholders of GCC projects in terms of planning future projects and better understanding of the dynamics of project management as lessons for reducing the incidences of project delay and high cost.

Delay Claims

Claims are considered to be one of the most serious disruptive forces to successful project delivery in the construction industry. In a small developing economy like Botswana, it is germane to identify the sources and the frequency of occurrence of claims so that the burden of project cost overrun, a hallmark of the country’s construction industry is substantially reduced. Detailed literature review and preliminary field investigations were used to identify causes of claims related to road construction projects. The study identified six major types of claim and twenty seven causes of claims. Using questionnaire as research instrument, respondents (construction industry major stakeholders i.e. clients, consultants and contractors) were asked to rank the frequency of occurrence of the types and causes of claims in road construction projects on a Likert-type scale. Relative importance index (RII) method was used to analyze the data collected from the questionnaire survey. The analysis was carried out for each group of respondents and on the overall results (all the parties combined). A total of 27 useful responses made up of nine clients, ten consultants and eight contractors) were analyzed. Findings indicated that the clients and consultants specified delay claims followed by extra work claims were the most frequent type of claims in the construction of roads in Botswana. Contractors perceived differing site conditions followed by delay claims as the most frequent type of claims. From the overall response, delay claims were ranked first followed by extra work claims. Acceleration claims were ranked least. The top five most frequent causes of claims based on overall ranking were: variation in quantities, design errors, poor site management and supervision by contractor, ineffective planning and scheduling of project by contractor, and low price of contract due to high competition. Construction industry research in Botswana has never looked into the issue of claims and yet it is one of the hidden sources of construction project failure in the country. It is perceived that hedging against the most adverse causes of claims will stem the tide of incessant cost overrun, litigation and project abandonment on road projects in Botswana.

Purpose The Nigerian construction industry is bedeviled with poor project performance and outcomes which value management (VM) could address if applied. The application of VM on Nigerian construction projects is very minimal due to certain obstacles, namely, lack of VM experts, paucity of knowledge on the techniques, etc., which inhibits the adoption into the construction industry. Therefore, this study aims to develop a conceptual framework of the adoption of VM on construction projects in a typical developing economy. Design/methodology/approach This study engaged 15 selected VM experts in two rounds of Delphi survey to develop a conceptual framework of VM adoption. The method of data analysis includes mean score, standard deviation, Kendall’s coefficient of concordance, chi-square (χ2) test, interrater agreement analysis and significant level analysis. The developed conceptual framework was sent to a team of local and international VM experts for validation. Findings This study reveals that the adoption of VM requires the collective effort of relevant stakeholders in the construction industry. The framework developed presents individual and collective activities to be undertaken by the stakeholders. The activities include training, legislation, government-funded research, etc. Thus, the adoption of innovative management methodology like VM requires the collaboration of academics, construction professional bodies and government parastatals. This will assist in the judicious use of limited construction resources and boost the relevance of the Nigerian construction industry among developing nations and in the global construction market. Originality/value This study used the opinions of few construction professionals that can be regarded as VM experts in Nigeria, as against engaging a pool of construction professionals who may not be knowledgeable in VM process. Engaging the few VM experts in the Nigerian construction industry is important to have a valid basis for drawing conclusion, as large questionnaire survey could be possibly filled by inexperienced or unqualified respondents if stringent criteria are not considered at the outset of this study.

Construction industry is considered to be one of the most important industries in Vietnam's economy. But many construction industry sectors have been experienced chronic problem as cost overrun. Therefore, a conceptual model of factors influencing construction cost was developed to determine the key factors that cause difference between budget cost and actual cost and some solutions are recommended to be applied to achieve the best outcome of cost. The result of analyzing 216 construction projects completed from 2002 to 2007 by companies located in Ho Chi Minh City indicated 6 main factors varying construction cost: project planners, project executives, economics, political, natural environment, fraudulent and lost. The results of multiple linear regression model confirmed the relationship between these above 6 factors and construction cost with the theories are supported at the statistically significant level of 0.05.

Design Bid Build

Design-Bid-Build (DBB) or commonly known as Traditional method is the earliest and most prevalent procurement method used in Malaysian construction industry. Design-Build (DB) and Construction Management (CM) procurement methods were later introduced in Malaysia as an endeavour to satisfy and accommodate the increase in project complexity and the need for avoiding drawbacks of the Traditional methods. Each procurement method has different nature and possesses certain characteristics. Therefore, this study was carried out to ascertain and compare the characteristics of these three procurement methods that are implemented in building construction projects in Malaysia. A questionnaire survey was conducted among architects, consultants, contractors and owners or developers to elicit their feedback on the characteristics which were categorised into time, cost, quality, complexity and flexibility, degree of involvement and responsibility allocation and technical expertise. The findings indicated that only DB method almost fulfils all the characteristics under the six categories, whereas, DBB methods garnered agreement only for certain characteristics under time, cost, complexity and flexibility and technical expertise categories. Meanwhile, the only CM method’s characteristics that satisfy agreement from the respondents are the often used of fast track approach and lack of certainty in price. This study concludes that when a procurement method is adopted for a construction project, not all the features or characteristics will turn out as expected. There are many factors that contribute and are influential on the success in procurement methods that are worth for further investigation.

Variation order refers to any changes from the scope, plan, specification or contract document in the construction project. This changes of work is a common problem in construction projects in Malaysia. It is inevitable in any construction project and this problem can become more serious when variation order causes work progress to be impaired as a results it increased the construction time and cost that affects the construction industry in Malaysia. This paper critically review the causes of variation order in the construction industry on the double-storey terrace housing project in Malaysia. The discussions began with the construction industry in Malaysia and then related parties involved in the construction industry. The extensive local and abroad literature review on the definitions of variation order and analysis of past studies conducted on variation order and the previous study of the prediction model of variation. The extensive literature on variation order in the construction of building project may help to improve the performance in term of time, cost and quality of the construction of building projects in Malaysia.

Probing Questions

  Construction industry in India is second largest next to agriculture. In current era of infrastructure development construction projects occupy a key position. In any construction project contract time and cost overrun is a common feature, which gives rise to claims leading to disputes. These disputes if not handled properly tend to consume time and money of all parties to the contract. To resolve the dispute in optimum time, it is essential to understand the root cause of disputes as early as possible. Hence there is a need of analyzing the disputes scientifically.  The present study reveals from the study of arbitration awards that the causes for delay claims can be grouped in domains and the probable decisions to the disputes can be traced through the probing questions considered by decision makers. This paper attempts to identify questions related to disputes for Indian scenario through literature, arbitration awards, court cases and discussions with professionals.

The construction industry in Malaysia is very important for creating employment, both directly and indirectly. It faces two repeated problems during the construction stage: slippage of project-schedules, i.e. time overrun and overrun of project cost; to the dislike of owners, contractors and consultants. This paper studies the time delay and cost overrun factors for Design and Build D&B projects in Malaysia. A Questionnaire was used to collect data from practitioners and analyse the responses and rank the factors and groups on overall view of the contracting parties. Identified risk factors from the theoretical domain were used to prepare 79 time related question and 18 cost related question categorized in 9 groups and 1 group respectively. Total of 136 respondents recorded their ratings to the factors in the questionnaire. Labour-related group has the top 1 rank with RII 0.684. The results can be used as a guideline to successfully handle construction projects in Malaysia; contributing for better project performance and lead to positive risks, opportunities.
