PPP Contract Delivery System - Contractual Risks and Ethical Issues Regarding Deep Foundation Subcontractors-Paper

Paper

Pdf Summary

The paper examines how Design-Build-Finance-Operate-Maintain (DBFOM) public-private partnerships (PPPs) affect deep-foundation subcontractors. In a PPP, a private consortium finances, builds, operates, and maintains a publicly owned asset over a long concession period. This model can accelerate delivery and encourage innovation and lifecycle-focused quality, but it also creates complex, long-term contractual relationships and shifts substantial risks from government to private parties.<br /><br />Deep-foundation subcontractors face pressure to meet aggressive schedules and demanding quality standards while adapting to design changes. They need strong financial capacity, change and cost management, and a collaborative role in design and construction. Late completion can threaten the project’s financing and revenue, making timely performance particularly important.<br /><br />The paper highlights significant payment risks. PPP projects may lack the payment bonds typically available on public works, while subcontractors generally cannot place liens on publicly owned assets. Payment protections vary by state statute. Subcontractors should identify the governing law, seek bonds or equivalent security, reject “pay-if-paid” terms, and negotiate prompt payment regardless of upstream payment. They should also limit indemnity obligations to insured personal-injury or property-damage claims caused by their negligence, and align additional-insured coverage with the contract.<br /><br />A major ethical concern is the transfer of differing-site-condition risk to subcontractors before sufficient site information is available. Subcontractors may be forced to submit an uncompetitive contingency, decline the work, or accept potentially business-threatening exposure. The authors also warn that shared corporate ownership between the general contractor and project company may compromise impartial claim review and increase non-payment risk. Trade associations can help address these problems through education and collective standards.<br /><br />To manage project risks, subcontractors should attach an agreed schedule to the contract, reserve compensation for unforeseen obstructions, establish unit prices for related work, and strictly follow claim-notice requirements. Overall, the paper argues that subcontractors can manage some contractual and operational challenges, but fair allocation of site, payment, and claims risks requires broader industry action.
