Design Build Operate MaintainEdit
Design Build Operate Maintain (DBOM) is a project delivery approach that merges the design, construction, operations, and ongoing maintenance of a facility into a single contractual framework with an integrated team. By aligning responsibilities across the life cycle, DBOM seeks to shorten procurement timelines, reduce coordination frictions, and deliver predictable performance over decades rather than just at the punch list phase. In practice, DBOM is most commonly applied to large public infrastructure and facilities where long-term reliability and uptime are critical, such as transportation hubs, water systems, and public buildings. The model is related to other integrated approaches like [Public-Private Partnerships] and Design Build arrangements, but it adds the operating and maintenance obligations that follow handover.
DBOM differs from traditional design-bid-build by removing the rigid handoffs between design, construction, and long-term operations. Instead of separate contracts, an owner contracts with a single entity (or an integrated consortium) responsible for the design, build, and long-term performance. The owner’s risk is reframed through performance specifications, service-level targets, and incentives tied to availability, reliability, and lifecycle cost. This integrated structure can help ensure that what gets built is easier and cheaper to operate over time, and that maintenance needs are anticipated from the outset. It also emphasizes data-driven management of assets, with ongoing reporting on trends in performance, energy use, and component life expectancy.

How DBOM works
Ownership and governance: An owner issues a request for proposals seeking a single integrated entity to handle design, construction, and operation/maintenance over a defined horizon. The contract specifies performance criteria, warranty terms, maintenance standards, and data reporting requirements. See Risk transfer as a design element in these arrangements.
Design and build: The selected team develops a comprehensive design that meets the owner’s objectives while incorporating long-term operability and maintainability considerations. The design team remains accountable for constructability and lifecycle implications.
Operation and maintenance: After commissioning, the same team operates and maintains the facility per agreed service levels. This creates an incentive to minimize downtime, optimize energy use, and extend asset life through proactive maintenance rather than reactive repairs. See Facilities management as a broader field of practice.
Performance management: The contract defines clear metrics, with incentives for exceeding targets and penalties for underperformance. Data collection, monitoring, and reporting are central to ongoing governance and decision-making. For context on how these metrics are framed, refer to Value for money and Total cost of ownership discussions.
Renewal or transition: At the end of the term, the owner may renew the arrangement, transfer operations to an in-house team, or select a new DBOM partner through a competitive process. The long horizon of DBOM requires careful planning for transition, data handover, and capacity building within the owner’s organization. See Contract management for related processes.
Benefits and rationale
Cost discipline over the life of the asset: When the contractor bears operating and maintenance risk, there is a strong incentive to pursue design choices that reduce long-term costs, not just upfront construction prices. See Life-Cycle Cost.
Faster delivery and fewer handoffs: Integrated teams can shorten procurement timelines and reduce clashes between design and construction. This can translate into earlier availability of the facility for public use or service delivery.
Predictable performance and reliability: With long-term responsibilities tied to performance targets, owners gain clearer accountability and more stable operating costs over time. See Performance-based contracting.
Innovation and standardization: An integrated mandate encourages standardization of components and maintenance practices, potentially lowering training costs and enabling better data-driven asset management. See Design-Build as a related standard approach.
Capability building in the private sector: For some regions, DBOM contracts foster a cadre of specialized firms with expertise in both construction and long-term facilities management, expanding the pool of capable suppliers.
Risks, governance, and oversight
Concentration of risk: A single partner assumes many responsibilities, which can magnify consequences if performance falters. Strong contract structure and continuous oversight are essential. See Risk management.
Upfront cost and long-term commitments: The owner commits to long-term obligations, which can constrain future flexibility or create financial commitments that outlive political cycles. Rigorous value-for-money analysis helps address this concern. See Value for Money.
Transparency and accountability: Long-term arrangements may reduce day-to-day visibility into pricing, changes, or maintenance practices. Open-book accounting and independent audits are common remedies in well-governed DBOM programs. See Public accountability and Audit.
Labor and wage considerations: Critics worry about privatizing essential services and the effects on wages, benefits, and local employment. Proponents respond that competition and performance standards can drive efficiency while preserving local staffing where appropriate. See Privatization for related debates.
Flexibility and change management: Major scope changes or evolving public needs can be difficult to accommodate within a long-term contract. Flexible contracting provisions and clear change-management processes are important.
Controversies and debates
Privatization versus public stewardship: Proponents argue that DBOM channels private-sector discipline and capital into essential infrastructure, delivering better value for money and faster delivery. Critics worry about ceded control over critical public services and the potential for price escalations over the life of the contract. In many debates, the core question is whether private-sector discipline improves or simply transfers risk without adequate public benefit. See Privatization.
Long horizons and political risk: DBOM arrangements often span beyond a single political term. Supporters contend that long horizons enable efficiency and maintenance planning; opponents warn that political changes can complicate governance, renegotiation, or terminations. See Public-Private Partnership as a broader frame for these tensions.
Cost comparisons and reporting: Critics sometimes challenge the method of comparing DBOM to traditional procurement, arguing that lifecycle costs and risk-adjusted prices are difficult to measure. Advocates respond that robust cost accounting, transparent methodologies, and independent verification can produce credible comparisons. See Life-Cycle Cost and Total Cost of Ownership.
Labor market effects: The interplay between public sector pay scales, private-sector wages, and workforce training can become a point of contention. Supporters contend DBOM creates skilled, stable employment opportunities tied to asset performance, while critics push back against outsourcing essential public services. See Labor relations.
Woke criticisms and policy critiques: Some observers argue that DBOM is a step toward excessive privatization or reduced public scrutiny. From a pragmatic, market-oriented stance, proponents reply that well-constructed DBOM contracts preserve public accountability, deliver measurable performance, and protect taxpayers by tying pay to outcomes. Critics who overemphasize ideology may miss the practical checks and balances embedded in strong procurement rules, independent audits, and performance-based incentives.
Implementation considerations and best practices
Clear, measurable specifications: Define performance targets, maintenance standards, uptime requirements, and safety metrics up front. Use objective, auditable metrics so incentives align with desired outcomes. See Performance-based contracting.
Open-book pricing and cost transparency: Require access to cost data, change orders, and pricing methodologies to prevent surprises and enable independent verification. See Audit and Contract management.
Balanced risk allocation: Allocate risk to the party best able to manage it, and include termination rights if performance does not meet agreed standards. See Risk transfer.
Data governance and digital asset management: Implement data standards for asset inventories, sensor data, and maintenance histories to support ongoing decision-making and future procurement. See Digital asset management.
Transition planning: Plan for knowledge transfer, staff training, and data handover when ownership or control shifts at contract milestones. See Change management.
Market engagement and competition: Encourage competition among capable DBOM teams, and ensure procurement processes are transparent to attract a diverse pool of bidders. See Public procurement.
Benchmarking and independent review: Use external benchmarks and periodic independent assessments to validate performance and cost claims. See External benchmarks.
