Methods Of Minimizing Delays Construction Essay

Methods Of Minimizing check overs Construction EssayA achieverful turn as certain(a) is accomplished when the stand out is neckd and hand over to the possessor within cadence, be, specifications and quality required and to the satisfaction of stakeholders. Thus, completing a formulation discover on sequence is vital as it secure the reforms of the dynamic parties on the find out. When a plan is griped, it lead cause the alternatives employed to be exceeded as what has been planned. This extra use of resources will lead to disputes and claims arise as extra damages will be incurred to complete the meet by the participating parties. Abd El-Razek et al. (2008) identify that heist in bend project is considered iodin of the most common problems causing a multitude negative picture on the project and its participating parties. Delays atomic number 18 insidious much resulting in time overrun, salute overrun, disputes, litigation, and complete abandonment of proj ects (Sambasivan and Yau, 2007).M either projects are of such(prenominal) a nature that the client will suffer hardship, expense, or sack of revenue if the work is resisted beyond the time specified in the hale. Then, again, see to it has cost consequences for the asseverator standby costs of non-productive workers, supervisors, and equipment, expenses caused by break complex body part and material delivery registers and additional overhead costs (Clough, 1986).Delay on project will affect the parties to the contract voluminous. Issues regarding entitlement to extra costs or prolongation of time for the project may arise as consequences to the project delay. Questions arise as to the causes of delay and the assigning of fault often evolves into disputes and litigation (Bolton, 1990). Thus, it is very burning(prenominal) to find protrude the methods with relevant to its causal movers of delay so that the cause of the delay on the project croup be quaild. This is bec ause the project delay itself and also the resolution of disputes are twain a waste of resources. It is important to predict and identify problems in the archean stages of grammatical gimmick and diagnose the cause to find and implement the most purloin and economical solutions (Abdul-Rahman and Berawi, 2002).Several seekes had been carried out to studied and recommended on methods to lessen delay in manifestation fabrication in their studies of attend into causes or causes and effects of delays in either specific types of construction projects or in general, representing the boilers suit construction industry.3.2 Methods of Minimizing Construction DelaysAssaf et al. (1995) in the literature re public opinion of his scan of investigating the causes of delay in large structure projects in Saudi Arabia, storied that studied by Chalabi and Camp (1984) suggested that in developing countries, where workers are comparatively unskilled, adequate cookery at the very early st ages of the project was important for minimizing delay and cost overruns in most projects.Chan and Kumaraswamy (1997) conducted a write up to see the causes of construction delays in Hong Kong as seen by clients, contractor and advisers, and examined the factors affecting productivity. This study also suggests or so(a) useful pointers towards minimizing the problems causing delays on construction point. interest are the recommendationsThe relationship amid achiever on site and untouchable focal point aggroups underlines the bedevil for impressive site precaution and supervision by contractors and consultants. Manpower, at both the adept and the arguerial levels, should have their own association up take cared by continuous professional development schemes. This may be in the form of short train programmes or day release courses in educational establishments.In fitted knowledge of the sites causes many delays in projects. The investigation of site conditions, toge ther with the jut of groundworks and foundations, should be thoroughgoing(a), complete and loosely presented before counterbalance of construction so as to reduce the impact of any unanticipated ground conditions. rough-and-ready data communication between various groups and levels involved in a project, emphasizes the need for efficient methods of entropy processing in the construction industry. To accelerate the communications and decision making among all parties, leave overall organizational structures and communication systems linking all project teams should be certain end-to-end the whole life of the project. The roles and responsibilities of those involved in the project team should be clearly defined, and the headingated decision- wreakrs should also be clearly identified.Comprehensive strategies need to be formulated to minimize variations, whether client-initiated or consultant-initiated, wherever possible. A clear and thorough client brief is considered the mos t useful strategy for cut down variations. Contingency allowances may be incorporated for inevitable variations. These allowances may be better quantified by using risk synopsis techniques. Strategies should also be formulated to mitigate the impact of such inevitable variations after obtaining the consultants advice, together with the contractors inputs, on their cost and time implications. Value management techniques may be useful both when developing the tendency from the brief at the abstract physical body stage, as well as in limiting any variations to those that are absolutely essential.The differentials in perception between the different groups of participants in the industry should be noted and discussed in suitable fora, with a view to bridging the gaps and avoiding or resolving some of the avoidable problems that have been highlighted herein.The results of the foregoing vision should be taken into consideration in developing a construction time prediction model for local building and civil engine room construction industries, as has been planned in the next phase of this research programme in Hong Kong.Noulmanee et al. (1999) investigated causes of delays in highway construction in Thailand. They suggested that delay can be minimized by discussions that lead to understandingAibinu and Jagboro (2002) conducted a study to survey the problem of construction delays in Nigeria. The study was carried out to examine the effects of delays on the delivery of the projects in Nigeria and some recommendations were do to minimize the effects of the projects delays. A questionnaire survey was done over 61 construction projects to determine and assessed the impact of the delay projects on its delivery. Time and cost overruns were found to be the common effects of construction delays. The recommendations made to reduce the impact of the construction delays wereAcceleration of site activities coupled with purifyd clients project management procedures andInc lusion of the contingency allowance in the pre-contract estimate.Chan and Kumaraswamy (2002), in their study of compressing construction duration in Hong Kong explored strategies used to compress construction durations for various types of building projects. The paper sought out the critical factors that run to the faster construction procedures in Hong Kong. The authors recommended specific technological and managerial strategies to be used to reduce the construction durations.Odeh and Battaineh (2002) in the study of causes of construction delay in traditional contracts suggested that to improve the situation of delays, a joint struggle by all participants in the construction industry is needed byEnforcing liquidated damage clauses and offer incentives for early completion. develop human resources in the construction industry through prudish training and classifying of craftsmen. This calls for providing incentives such as offering a tax deduction on money spent on training, a nd for authorizing trade unions or other agencies to regulate, follow-up on training, and classify trades. Developing human resources also applies to construction take aims who usually lack adequate managerial skills. on that point is an urgent need for offering training courses in scheduling, time and cost arrest, education systems, and management of human resources.Adopting a fresh begin to contract award procedure by giving less free weighting to prices and more weight to the capabilities and prehistorical performance of contractors.Adopting new greetes to contracting, such as design-build and construction management (CM) types of contracts. Such contracts reduce delays by limiting owner interference, improving the design, and improving the contractual relationships among all parties to the project.Frimpong et al. (2003) give some recommendations minimize delays in the study of causes of delay and cost overruns in the construction of groundwater construction projects in gold coast. Their recommendations are as followsAppropriate funding levels should always be determined at the planning stage of the project so that uniform payment should be paid to contractors for work done.In order to improve contractors managerial skills there is need for continuous work-training programs for personnel in the industry to update their knowledge and be familiar with project management techniques and process.sound and efficient material procurement systems should be established within projects. hooey procurement has the potential to cause major delays to construction projects. Therefore, material procurement process should be executed properly by improving procurement process in order to avoid supply delays.Developing strong and efficient expert performances in the groundwater industry through different types of training programs. The training should covert project planning, scheduling, time and cost control, and the information systems.There should be adequat e contingency allowance in order to cover increase in material cost due to inflation.Nguyen et al. (2004) studied the project success factors in large construction projects in Vietnam. Factor analysis was employed to categorize these success factors perceived by 109 respondents from 42 construction-related organizations. The success factors identified in this study wereClear objectives and scope consignment to projectTop management mountTimely, valuable information from different partiesEffective strategical planningAwarding bids to the right designer/contractor chronic involvement of stakeholders in the projectFrequent kick upstairs meeting tolerable funding throughout the projectAvailability of resourcesAbsence of bureaucracy club involvementClear information and communications channelsAccurate initial cost estimatesSystematic control mechanisms satisfactory project managerMultidisciplinary/adequate project teamComprehensive contract documentationUp to date technology utilizati on andproper emphasis on past experience. quintette critical success factors were identifiedCompetent project manager comme il faut funding until project completionMultidisciplinary/adequate project teamCommitment to project andAvailability of resources.Obviously, the factors shown are mostly human-related factors. This implies that people play a decisive role regarding the success or failure of a project.Further, factor analysis uncovered that most of the success factors can be group under four categories, here titled the four COMsComfort concerns ensuring that resources, efforts and leading are well aligned for the implementation of the project. It includes adequate funding throughout the project, comprehensive contract document, availability of resources, continuing involvement of stakeholders, and fitting project managers.Competence requires having appropriate technology, experience, and specialties accessible for the project. It includes up to date technology utilization, p roper emphasis on past experience, multidisciplinary/competent project team, and awarding bids to the right designer/contractor.Commitment chequers that all parties concerned with the project and all levels in the management hierarchy of each participating organization are ordain to manage, plan, design, construct and operate the facility harmoniously. It includes commitment to project, clear objectives and scope, and top management support.Communication helps clarify and disseminate all necessary project information and status to all internal and external project stakeholders. The project will then have the opportunity to avoid failure and reach for success through the achievement of team-spirit and a sense of ownership. It includes community involvement, clear information/communications channels, and frequent increase meeting.Koushki et al. (2005) recommended some suggestions which could be used to minimize time delays and cost overruns in the study of investigating the delays and cost increases in the construction of private residential projects in Kuwait. They suggested that the owner of a new residential project in Kuwait toEnsure adequate and available source of pay carry out a preconstruction planning of project tasks and resource needsAllocate sufficient time and money on the design phaseIf cost- efficient (depending on the size of the residential project), hire an independent supervising engineer to monitor the progress of the work and ensure apropos delivery of materials and finally, the most important factor of all,Select a competent consultant and a reliable contractor to carry out the work.Assaf and Al-Hejji (2006) suggested some recommendations that pointed out by all parties which are the contractors, consultants and owner to minimize and control delays in construction projects.Owners should give special attention to the following factors salary progress payment to the contractor on time because it impairs the contractors ability to financ e the work.Minimize change orders during construction to avoid delays.Avoid delay in reviewing and approving of design documents than the anticipated.Check for resources and capabilities before awarding the contract to the final bidder.Contractors should consider the following factorsShortage and low productivity of labour large number of labours should be designate and be motivated to improve productivity. monetary and bills flow problems contractor should manage his financial resources and plan cash flow by utilizing progress payment.Planning and scheduling they are continuing processes during construction and match with the resources and time to develop the work to avoid cost overrun and disputes.Site management and supervision administrative and technical lag should be assigned as soon as project is awarded to make arrangements to achieve completion within specified time with the required quality, and estimated cost.Consultants should look to the following pointsReviewing a nd approving design documents any delay caused by the consultant engineer in checking, reviewing and approving the design submittals prior to construction phase, could delay the progress of the workInflexibility consultants should be flexible in evaluating contractor works. Compromising between the cost and high quality should be considered. at last Architect/design engineer should focus on the following issuesProducing design documents on time Architect/engineer should set a schedule to complete design documents on time, otherwise result in a delay of work completion.Mistakes and discrepancies in design documents they are common reasons for redoing designs and drawings and may take a long time to make necessary corrections.Ibnu Abbas Majib (2006) in his study of causes and effects of delay in Aceh construction industry, Indonesia suggest some methods which can be employed to minimize construction delays. A positive of thirty five methods of minimizing delays were identified in his study. The most effective methods of minimizing delays identified are toEnsure adequate and available source of finance until project completionCompetent project managerAvailability of resourcesFrequent progress meetingAwarding bids to the right/experience consultant and contractor rehearse of experienced subcontractors and suppliersMultidisciplinary/competent project teamAccurate initial cost estimatesCompetent and exposed of clients representativeUse of appropriate construction methodsPerform a preconstruction planning of project task and resources needs andProject management assistance.Abd El-Razek et al. (2008) conducted a similar study of causes of delay in building construction projects in Egypt from the point of view of contractors, consultants, and owners suggested that in order to significantly reduce delay a joint effort based on teamwork is required.Fugar and Agyakwah-Baah (2010) show in their study of delays in building construction projects in Ghana from the perspect ive of clients, consultants and contractors that the adequate and timely provision of financial resources in building construction project management cannot be over emphasized. This is because the finance is the hub just about which everything else revolves. Everybody and everything connected with construction is adversely affected by lack of sufficient cash flow. They made the some recommendations as followsConstruction clients essential ensure that funds are available or adequate arrangements for funds are made before projects are started.The long and bureaucratic processes involved in honouring payments to contractors in Ghana must be shortened for efficiency and contractors payments must be honoured as and when they due in strict compliance with the sustenance of the contract.Contract provisions which allow contractors to claim interest on retard payments must be strictly visitd to serve as obstruction to clients.The idea of establishing a commercial bank for building and construction is deserving revisiting so that contractors can have access to credit in measure of liquidity difficulties.On the other hand, to overcome some contractors ineptitude which correlates straightway with delay factors such as underestimation of cost, time of completion and complexness of projects, poor scheduling and control and poor site management, the researchers recommend the following actions.The Civil Engineering and Building Contractors Association of Ghana must comprise measures to ensure that its members go through continual education so that the technical and managerial competences of contractors who belong to it can be improved. The acquisition of a certain number of credit hours in continual education should be a criterion for membership renewal.The Ministry of Works and Water Resources, the body responsible for the accommodation and classification of contractors wishing to execute public projects, must insist on its requirement that contractors must have i n their employment certain happen upon technical supply as a condition for registration. Above all, effective ways must be designed to verify the list of staff produced by contractors in support of their application and to ensure also that these mention staff positions are continually filled by technically competent individuals.Summary53 methods of minimizing delays were identified from the review of literature above. These methods will be used to develop questionnaire for surveying purposes. Followings were the methods identifiedPerform a preconstruction planning of project tasks and resources. around-the-clock update manpower, both technical and managerial.Thorough and complete investigation of site conditions.Clear information and communications channels.Clear and thorough client brief.Include of the contingency allowance in the pre-contract estimate.Use assess management techniques when developing the design from the brief at the conceptual design stage, as well as in limiti ng any variations to those that are absolutely essential.Accelerate site activities.Improve clients project management procedures. administer liquidated damage clauses.Offer incentives for early completion.Adopt a new approach to contract award procedure by giving less weight to prices and more weight to the capabilities and past performance of contractors.Adopt new approaches to contracting, such as design-build and construction management (CM) types of contracts.Determine appropriate funding levels at the planning stage of the project.Effective and efficient material procurement systems.Competent project manager.Multidisciplinary/competent project team.Commitment to project.Allocate sufficient time and money on the design phase.Hire an independent supervising engineer to monitor the progress of the work.Pay progress payment to the contractor on time.Minimize change orders.Avoid delay in reviewing and approving of design documents.Check for resources and capabilities before awardin g the contract to the lowest bidder.Number of labours assigned should be enough and be motivated to improve productivity.Contractor should manage his financial resources and plan cash flow by utilizing progress payment.Continuous planning and scheduling during construction.Site management and supervision administrative and technical staff should be assigned as soon as project is awarded to make arrangements.Produce design documents on time.Avoid making mistakes and discrepancies in design documents.Consultants should be flexible in evaluating contractor works. Compromising between the cost and high quality should be considered.Clear objectives and scope.Frequent progress meeting.Top management support.Timely, valuable information from different parties.Effective strategic planning.Award bids to the right/experience consultant and contractor.Continuous involvement of stakeholders in the project.Availability of resources.Absence of bureaucracy.Community involvement.Systematic control mechanisms.Comprehensive contract documentation.Up to date technology utilization.Proper emphasis on past experience.Use of experienced subcontractors and suppliers.Accurate initial cost estimates.Competent and capable clients representative.Use of appropriate construction methods.Project management assistance.Idea of enforce contract provisions which allow contractors to claim interest on hold up payments must be strictly to serve as deterrent to clients.Establishing a commercial bank for building and construction so that contractors can have access to credit in times of liquidity difficulties.Design effective ways to verify the list of staff produced by contractors in support of their application and to ensure also that these key staff positions are continually filled by technically competent individuals.
