Road construction is the important division in the construction industry and the most predominant part of a society. The roadway defines the development of a country or a state and brings in the economic development of the same. The reasons for choosing a project on the roadways are its vast scope of day to day development and progress in this area. Thus it is clearly seen that roadways is the most essential in todays world without which progress and development cannot take place at full fledge. Therefore any delay in completion of a road constructing project may have its impact in degrading of a society. Also at the same time the budget overrun or cost overrun of such project is highly unbearable.

In this paper, we consider a simple chemostat model with inhibitory exponential substrate uptake and a time delay. A detailed qualitative analysis about existence and boundedness of its solutions and the local asymptotic stability of its equilibria are carried out. Using Lyapunov–LaSalle invariance principle, we show that the washout equilibrium is global asymptotic stability for any time delay. Using the fluctuation lemma, the sufficient condition of the global asymptotic stability of the positive equilibrium [Formula: see text] is obtained. Numerical simulations are also performed to illustrate the results.

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.

Water construction projects in Iran frequently face problems which cause cost overrun and time delay, the two most common issues in construction projects in general. The objective of this survey is to identify and quantify these problems and thus help in avoiding them. This survey represents a collection of the most significant problems found in the literature, classified into 11 groups according to their source. The questionnaire form used contains 84 questions which were answered by random engineers who work in water construction projects. The Relative Importance Weight (RIW) method is used to weight the importance of each one of the 84 problems. The focus of this survey is on overall top ten issues which are: bureaucracy in bidding method, inflation, economical condition of the government, not enough information gathered and surveys done before design, monthly payment difficulties, material cost changes, law changes by the government, financial difficulties, mode of financing and payment for completed work and changes made by the owner. A section for each of these issues provides additional information about them. In the full text of this survey the same weighting method is used to classify the main groups, and the results show that issues related to the groups of government, owner and consultant has the most significant impact. The last part of this survey describes the point of view of the engineers who took part in this survey and the recommendations they made.

Time delays and cost overrun are still a "scourge" in construction projects. The most important factors that cause these two risks are ineffective project planning and scheduling, and inaccurate quantity taking off. Thus, it is most appropriate to carry out mitigation since the project planning period. With the fact of increasing stadium construction in various countries, with iconic and futuristic design, and containing national pride, must be a serious concern so that the risk of time delay & cost overrun can be reduced. Because stadiums are like that usually involve a complex structural system, complicated installation technique with strict network diagrams. The M-PERT & BIM 5D - Based Quantity Take Off method has the potential to mitigate and minimize this risk. This study, with the RII simulation, reveals the critical success factor for applying the potential of this method, especially in stadium structural work. These factors can become a serious concern for construction practitioners, especially in Indonesia, who are and will build stadium projects. Keywords: Structure; Stadium; M-PERT; BIM 5D; RII.

Globally the utilization of metros is incredibly common for transportation for convey individuals at one place to a different for convey individuals at one place to a different with ease. Infrastructure os Asian nation project ill-framed for time delay and rate value flooded. Globally there many analysis for estimating cost and time delay with analytical, case study and downside that are the factors inflicting time delay and rate value flooded which are found by using Rankin’s constant techniques, Risk performance technique, Time delay and cost overrun index, CPM & PERTS, Monte’s Carlo Simulation Techniques, Budget dominant and change and Milestone chart etc are such type of methodologies applies to seek out project’s time delay and cost overrun in Infrastructure project. This paper the methodology accustomed ascertain expected time and cost in Mumbai underground metro rail passageway (MUMRP) by victimization application of Monte’s Carlo Simulation Techniques (MCST), during this we have a tendency to use network flow chart for locating out trial and error based mostly to create activities as essential path technique (EPT) by given downside statement and also outcome in terms of results and conclusion.
