Infrastructure in BIM is a major transformation in the civil infrastructure industry. This type of construction has recently become more popular for infrastructure construction, whereby the construction and academia-industry are putting effort into infrastructure BIM implementation and study; however, there has yet to be a specific review on information needs by phases. Therefore, this study is to collect the earlier investigations on the information needs for BIM in infrastructure at every construction phase. This article presents BIM information that requires common practice in various civil infrastructure projects. The basic development of BIM for infrastructure is emphasised in this observation. Through this observation, various information needs were established throughout the infrastructure construction. This article helps to ensure that all information is used at the right time at every phase to prevent any redundant information that might accrue overload data in the cloud throughout the coordination process. This information is essential for all participants in the BIM project, especially for those involved with the design and construction phases.

It is imperative to create awareness of the extent to which such delays can adversely affect project delivery, especially with regard to road construction projects. It is clear that the Libyan road construction industry also faces the issue of not being able to complete projects within the allocated time. This paper identifies the effects of road construction delays, evaluates these through a questionnaire, and assesses them using an empirical method. A detailed review of related literature produced the secondary data, while the primary data was obtained via a structured questionnaire which targeted the road construction projects owners, consultants and contractors. A 71% response rate was achieved; 256 out of the 360 questionnaires sent out were returned. Descriptive statistics were used to analyze the data received from the questionnaires. The findings of the study reveal that the major outcomes of road construction project schedule overruns in Tripoli, Libya include cost overruns, time extensions, disputes, loss of profit, breaches of contract, poor quality of work and company's bad reputation. The study makes a contribution to the knowledge of the subject of the outcomes of road construction project schedule overruns in Tripoli. Computation of the means and standard deviations, together with a structural equation model, have been used for the data analysis and inference. It is found that delays in road construction projects widely lead to cost overrun, time overrun, litigation and disputes. The findings of the study also provide significant insights into the construction industry, which will help it formulate strategies in order to avoid delays and their consequences. The most important effects identified were time overrun, cost overrun and obstruction of economic and country development.

To obtain a good ranking, the universities should provide comprehensive physical facilities and infrastructure. This study is to investigate the construction process to know the causes behind the delay process in constructing the high education facilities in the Malaysian universities. The Rasch model technique is applied to analyse the results, and the sample of this study included 100 respondents where the majority are managers and owners of the construction of the high learning institutions. The delay causes are grouped into three factors, there are input factor, internal factor and exogenous factor. It is revealed that internal factors were the most factors that contribute in delay construction process, the factors as follows: poor monitoring by the contractor, lack of consultants experience, changes in design, too many variation orders by owner, delay in making decisions by project owner.

This process consumes high commitment, cost and time by academicians and support staff in preparing the document that may divert their attention from performing their real task of teaching, researching and publicizing. Five key criteria are involves in accreditation i.e. curriculum, students, academics and support staff, facilities and quality management systems. In obtaining accreditation, an accreditation report should be produced and submitted for evaluation by the EAC committee. The difficulty of gathering is the most important evidence of information and materials in the absence of a proper recording and monitoring information system in place. In the philosophy of 'do thing right first' a structured information system namely 'Perisian Dokumentasi Akreditasi' (MyPDA) is proposed to be developed and data map needs to be first identified as an initial work of this research.
