HOW IT project cost overruns can be avoided?

Keep an eye on progress – To prevent cost overrun, keep an eye on project progress. Utilize project management tools to identify smaller issues and prevent them from growing into bigger problems that can threaten project success. Gantt charts allow you to keep an eye on the project timeline, team workload, and any slippages in real-time.

What are the causes of time and cost overruns on projects?

Major causes of construction time and cost overruns: A case of selected educational sector projects in Ghana (Business School, Ghana Institute of Management and Public Administration, Accra, Ghana ) (Business School, Ghana Institute of Management and Public Administration, Accra, Ghana ) (Business School, Ghana Institute of Management and Public Administration, Accra, Ghana ) In Ghana, the duration of construction projects from inception to completion is becoming a great concern, recently, especially among clients and beneficiaries, because of the rising interest rates, inflation, development plan targets, among other factors.

Hence the need to understand the causes of delays and cost overrun in the construction sector has become more important than ever. This study therefore aims to identify the major factors underlying time and cost overruns in projects related to the education sector in Ghana to proffer practical solutions in addressing them.

The study conducted a survey among clients’ consultants and representatives of the contractors working on about 60 government school projects. A relative importance index was used to determine the relative effects of the factors causing construction time and cost overruns.

The key factors causing construction time overrun were: financial problems, unrealistic contract durations imposed by clients, poorly defined project scope, client-initiated variations, under-estimation of project cost by consultants, poor inspection/supervision of projects by consultants. Other factors were underestimation of project complexity by contractors, poor site management, inappropriate construction methods used by contractors and delays in the issuance of permits by government agencies.

Factors affecting cost overruns were financial difficulty by client, delays in payments of completed works, variations in designs, lack of communications plans, poor feasibility and project analysis, poor financial management on site and material price fluctuations.

  • The research was limited to only the educational sector projects.
  • Practically, this study highlights for the construction sector the critical factors causing project time and cost overruns in Ghana.
  • Identification of these factors provides the basis for pragmatic solutions to enhance the chances of project success.

The identification and solutions to project time and cost overruns, especially for educational sector projects, contribute toward making public goods more affordable and accessible to most citizens, particularly in developing countries. This study contributes to the debate on factors causing project time and cost overruns in the construction sector especially from a developing country’s perspective. ,, and (2017), “Major causes of construction time and cost overruns: A case of selected educational sector projects in Ghana”,, Vol.15 No.2, pp.181-198. : Emerald Publishing Limited Copyright © 2017, Emerald Publishing Limited : Major causes of construction time and cost overruns: A case of selected educational sector projects in Ghana

What are the main reasons of time overrun in your projects?

Director at QS QUOTE LIMITED – Published Sep 6, 2015 Delay and cost overrun are inherent part of most projects despite the much acquired knowledge in project management. Although some may argue that this is negligible It is important to note that physical and economic scale of projects today is such that it is driven under the platform of profit to the parent organization, and of national interest (for government projects) by the degree of success defined within the Iron triangle of cost, time, and scope.

One major factor that has been identified as reasons for cost overrun in most projects is design errors, It is important to note that proper representation of client’s requirement and the blue print to achieving good technical input to project execution are usually mapped out base on project designs. Thus a design with errors practically means wrong or insufficient representation of project deliverables. This will lead to wrong application of techniques in achieving result, such that as the actual execution phase of the project unfolds these design errors, attempt to correct it will lead to delay and cost overrun. Another way design errors could lead to cost overrun and delay could be seen in the fact that project estimations are done base on the produced designs, as such, having errors in design in a form of omission or misrepresentation will mean that the estimation for the project cost will also include these omissions, thereby leading to extra works, change order etc., thus resulting in delay and cost overrun, Similarly, designs that are done without extensive investigation of site could contain potential errors. This is because such designs could lead to additional work, revision of scope of work, and contract revision as the actual site conditions begins to float up at the construction phase of the project. These will no doubt affect the overall project delivery time and cost. Causes of design errors cited in most projects are inadequate field investigation, error in design and specifications, plan errors, design changes etc. In controlling project delay and cost overrun due to design errors, the basic thing to be considered is the involvement of professional skills and application of competent tools throughout the project. Achieving error free design entails good communication with the entire design team and integrating a design process that is properly planned, giving enough time for corrections, extensive investigation and reviews. Similarly, an effective project planning, controlling and monitoring should be established to enhance project performance throughout the project life cycle. Proper site investigation should be done to ensure that all site conditions are noted in the design, and application of value management could be use to obtain the best Cost effective design options.

Delay and cost overrun in project could be as a result of scope change, Scope is the term that defines the entire deliverables that is expected at the end of a project. Therefore, logically, it can be said that all project plans, estimation, schedule, quality and base lines are usually designed base in the initial project scope. Thus, any change in the project scope during execution will mean that the entire initial project plan will have to be reviewed such that a reviewed budget, schedule and quality will have to be developed. This means more time and resources will be needed as against the initial baseline. “With each scope change, precious project resources are diverted to activities that were not identified in the original project scope, leading to pressure on the project schedule and budget”. Project scope change could be as a result of wrong initial scope definition, inherent risk and uncertainties, sudden change of interest, project funding change, etc. this could lead to change request which in turn could lead to change in project deliverables, budget and/or even the entire project team. Poor scope change management could lead to dispute that may require spending time and money on arbitration and litigation for what the contractor or the client believes he is entitle to. This will no doubt lead to delay and cost overrun of the project. To achieve a proper control for scope change, it is important to first identify the fact that change is inevitable in project and could equally be beneficial to the entire project success. Thus the most important thing to do is to integrate a proper change management plan such that a proactive approach could be adopted involving the project stakeholders and incorporating their needs throughout the project lifecycle. During the planning phase of the project, it is important to identify the key success factor in conjunction with the client and establish KPI in the form of milestone that will measure the success for of attaining the project scope. Similarly, to avoid disputes, it is important to always seek approval for changes from sponsor and communicate changes in a timely way. For highly evolving change in project, the scope could be frozen so as to concentrate on the expected deliverable.

Another major reason for cost overrun and delay in project is inappropriate and inadequate procurement and faulty contractual management system. Contracts read out virtually every aspect of a business correlation, including payment terms, pricing, and service levels. Therefore a contract that has not highlighted the entire project scenario may lead to dispute in the contract system. For instance, if the initial contract does not completely specify every relevant aspect of the project work, this may lead to long chains of negotiations, arbitration and/or mitigation due work change orders and the quest for reviewed contractual agreement with new budgets and schedule. The result will no doubt be a project delay and cost overrun. Similarly, ambiguous contractual agreement with unclear clauses can be of potential dispute thus generating delay and cost overrun in project. In the same vein, delay and cost overrun could be inherent in terms of poor contractor selection and unethical behaviour, contract bid amount, difference between the winning bid and second bid, difference between the winning bid and the engineer’s estimate, etc. and since majority of projects are executed by contractors, it is important to note that procurement process and contract management is critical to the successful completion of projects. Thus poor selection of contractors due to low bids, with no technical capability to handle the project will lead to cost overruns, schedule delays, poor quality, and a final result that is not acceptable. Also, a contract management system with clients that have a slow payment schedule could lead to delay and cost overrun. To solve these problems, the needful and ethical thing to do is to firstly identify the most qualified contractor via an ethical tender system and draft out the most suitable contract type as applicable to the conditions of the project and also explicitly define the terms and conditions that govern the contract in clear clauses. These clauses should spell out the penalties associated to delays and cost overruns and the party to bear risk associated to these events. Similarly all important potential dispute contract clauses should stated in clear unambiguous terms. The use of generic contract templates should be avoided and “careful consideration should be done when forming the contract, about what might happen during its operation, this will ensure that things are included in the contract documents that enable effective contract management.

The complexity of project could also be a contributing factor to delay and cost overrun. Complexity could be define in terms of the size of the project, most mega projects tend to have relatively long implementation period when compared to small project. This could be affected by inflation, change in material price and changes in exchange rates such that the initial budget may need to be supplemented for the project to be completed. The result could be cost overrun and long chains of negotiation which will lead to delay. Similarly, projects with high degree of complexity usually result in complex plans, schedules and estimations. Such that if care is not taken the tendency of omitting certain aspect of the project plans and/or estimation could be prominent, thereby leading to change orders. This could lead to delay and cost. Also, project complexity could also be defined in term of the diversity of stakeholders with different interest and long chain of communication channel with slow feedbacks. Therefore integrating their interest could take a lot of time and resources which when overlooked could result in conflicts and dispute, thus affecting the project in the context of delay and cost overrun. To eliminate or reduce the effect of delay and cost overrun due to project complexity, vigorous planning should be done, incorporating every important aspect of the project scope, milestones, detailed WBS, delivery time, stakeholders, and methodology to be used. “Managing complex projects needs experience, expertise and exposure”. Thus Project needs its goals and scope to be defined, based on the client requirements. This helps the project to be kept on track and ensures doing only the job that is intended. It is therefore important to build a good team with project success interest at heart to achieve this.

  1. Finally, the post execution phase (closure) of a project contains potential factors that can lead to delays and cost overrun. Being the very last part of the project life-cycle it is often been ignored even by organizations, especially in multi-project environments. Slow closeout could be seen as dragging the various handover activities course by unresolved disputes linked with client acceptance, contracts and procurement, change order issues not resolved, final change orders not issued, poor close out of final account, poor documentation of project success and lessons learnt, slow client acceptance and failing to close the work order can allow unexpected delay and stray charges to be made to the project. For instance if project team is not decommissioned on time after the project work has been completed, their exist a tendency of running an idle team that may incur extra project expenses due to overhead and this may overrun the project cost. Similarly, delay in payment of contractors and suppliers after project completion could lead to dispute and delay in signing the certificate of final completion of the project. Delay and cost overrun of slow closeout can be avoided when the project closure phase is implemented as planned.
    1. Completion: Ensure that the project is 100% completed to avoid disputes and delay in payments.
    2. Documentation: Detail documentation will ensure that future changes are made with little extraordinary effort.
    3. Project system closure: this includes closing the financial system ie all payments, work termination, etc.
    4. Project review: this can help in transfer of tangible knowledge of time and cost, know-how and know-why.
    5. Disband project team members and complement achievement as soon as possible to avoid cost overrun due to extra overhead.
    6. Stakeholder satisfaction: provide all the necessary information required by stakeholders to avoid conflicts and doubt. “This information can include a timeline showing the progress of the project from the beginning until the end, the milestones that were met or missed, the problems encountered and a brief financial presentation”.

In conclusion, although delay and cost overrun may seem very inherent in most projects, the good news is that it can be reduce or totally eliminated using a proper project performance monitoring and control system that will integrate all the key activities of each phase of the project.

This system could be designed such that a close loop information feedback and feed forward package is obtained from definition to close out of the project. The cycle is usually advantageous because planning, measuring, monitoring, and taking corrective action are all usually included in the control cycle.

Other additional tactics used to achieving a project with little or no delay and cost overrun is in the definition of project success factors and criteria. The integration of these factors will lead to a better understanding of the issues in which the project manager needs to address and design a control system that will monitor these issues.

  • What are reasons for time overrun?
