The Risks of Undefined Provisional Sums
Provisional sums are amounts included in building contracts to cover work that is not yet fully specified. When these sums are undefined, they pose substantial risks to both contractors and employers. Contractors face uncertainty because they cannot accurately plan, program, or price these sums, potentially leading to unexpected financial and scheduling impacts. This uncertainty often shifts the risk to the employer, who may ultimately bear the full cost and any delays arising from undefined provisional sums.
Challenges of Defined Provisional Sums
Even when provisional sums are defined, they can still present significant building contract risks. Contractors might include excessive contingencies to mitigate the risks associated with these sums. Moreover, if an employer decides to omit work related to a defined provisional sum, contractors might claim for loss of profit. Negotiating the actual costs and time impacts of defined provisional sums can also lead to disputes, further complicating the project and increasing the risk of cost overruns.
Cost Overruns and Project Disputes
Accurately estimating provisional sums is crucial for avoiding cost overruns and project disputes. Whether defined or undefined, inaccuracies in these sums can lead to financial disagreements and project disruptions. Effective management of provisional sum-related issues requires meticulous documentation and clear communication between all parties. This approach helps to mitigate cost overruns and resolve disputes before they escalate.
Conclusion
Provisional sums, whether defined or undefined, carry significant risks that must be carefully managed. Employers need to plan for these risks, potentially incorporating them into their risk registers. Clear contract provisions, effective collaboration, and robust documentation are essential strategies for mitigating the challenges posed by provisional sums. By addressing these issues proactively, all parties can work towards the successful completion of the project.
