Unlocking Value in Alliance Contracts Through Subsurface Risk Identification

Alliance contracts and SUE improve collaboration, early risk management, and cost certainty by addressing subsurface uncertainty in project design.

As infrastructure projects become more complex and the cost of delays rises, alliance contract models are gaining popularity as a collaborative alternative to traditional delivery methods. These agreements unite clients, designers, contractors, and service providers under a single contract that emphasizes shared risk, reward, and decision-making. Built on transparency and joint accountability, alliance contracts promote early stakeholder engagement, proactive planning,risk mitigation and innovation. By aligning incentives around common goals for time, cost, quality, and safety, they reduce adversarial dynamics and foster real-time collaboration. In contrast, traditional models like design-bid-build often discourage early risk identification, leading to inefficiencies and reactive problem-solving.

Since unknown underground conditions are difficult to quantify and carry a high degree of uncertainty, they are often left unaddressed in initial bids. Contractors may be reluctant to take on liability for these unknowns, and clients/owners may avoid the additional upfront cost of investigating them thoroughly. As a result, the subsurface is frequently treated as someone else’s problem—until it’s too late.

Rather than proactively identifying underground infrastructure and incorporating it into the design phases, traditional models often rely on change orders to deal with unforeseen conditions as they arise. This reactive approach can be costly, disruptive, and adversarial, with each party focused on protecting their own interests rather than working together to resolve issues. In some cases, the profit model itself becomes dependent on these change orders, creating a disincentive to resolve subsurface uncertainty early. Alliance contracts flip this dynamic. Because risk and reward are shared, all parties have a vested interest in identifying and managing subsurface conditions as early as possible.

Incorporating Subsurface Utility Engineering (SUE) and Site Characterization into the design phase allows for better-informed decisions, greater cost certainty, and smoother delivery. Teams can develop a unified understanding of what lies beneath the site and use that information to shape decisions before construction begins.

By delivering high-resolution information about underground conditions, SUE and geophysical investigations—including methods like Ground Penetrating Radar (GPR), Electrical Resistivity Tomography (ERT), and Multichannel Analysis of Surface Waves (MASW)—enable design and construction teams to identify potential risks, resolve conflicts before they occur, and reduce the likelihood of delays.

To ensure reliability and transparency, SUE work is best performed in accordance with ASCE 38-22, the recognized industry standard for classifying and managing utility data. This standard helps align expectations across disciplines by providing a consistent framework for assessing data quality and source reliability.

SUE deliverables can also be provided in fully georeferenced 3D models, which can be directly integrated into Building Information Modeling (BIM) platforms. Incorporating underground infrastructure into BIM enhances coordination, improves clash detection, and reduces the likelihood of costly rework—particularly in urban, congested, or technically constrained environments.

Everyone benefits when underground infrastructure is treated as a shared responsibility and a critical design input—not an inconvenient unknown to be deferred. Alliance models encourage embracing the opportunity to understand sub-surface risks early in the project, enabling effective risk mitigation and costing of risks. This early investment in understanding subsurface conditions supports better outcomes, more resilient planning, and a more collaborative project culture.

Frequently asked questions

What makes alliance contracts different from traditional delivery models?
Alliance contracts bring clients, designers, contractors, and service providers into one shared agreement that emphasizes transparency, joint decision-making, and shared risk and reward. This structure encourages collaboration and reduces the adversarial behavior often seen in traditional models.
Why are unknown underground conditions such a challenge on infrastructure projects?
Subsurface conditions are hard to quantify and carry significant uncertainty, so they are often not fully investigated during bidding. That leaves liability unclear, discourages early action, and can turn underground issues into costly surprises later in the project.
How does a traditional contract model usually handle unforeseen subsurface conditions?
Traditional models often address unexpected underground conditions through change orders after they are discovered. This reactive approach can increase cost, cause disruption, and create disputes because each party tends to protect its own interests.
How do alliance contracts improve the management of underground risk?
Because risk and reward are shared, alliance contracts give all parties a reason to identify and manage subsurface conditions early. This encourages proactive planning, reduces uncertainty, and supports better project outcomes.
What role do SUE and site characterization play during design?
Subsurface Utility Engineering and site characterization provide better information about underground conditions before construction starts. That helps teams make informed design decisions, improve cost certainty, and avoid conflicts later.
Which geophysical methods are mentioned for investigating underground conditions?
The content identifies Ground Penetrating Radar (GPR), Electrical Resistivity Tomography (ERT), and Multichannel Analysis of Surface Waves (MASW) as geophysical methods that can help reveal subsurface conditions and reduce project risk.
Why should SUE work follow ASCE 38-22?
ASCE 38-22 is the recognized standard for classifying and managing utility data. Following it helps ensure reliability, transparency, and consistent expectations across disciplines by clarifying data quality and source reliability.
How can SUE deliverables support BIM workflows?
SUE deliverables can be created as fully georeferenced 3D models that integrate directly into BIM platforms. This improves coordination, clash detection, and planning for projects in dense or technically constrained environments.
What benefits come from addressing subsurface uncertainty early?
Early investigation of subsurface conditions improves cost certainty, reduces delays, supports better risk mitigation, and leads to more resilient planning. It also encourages a more collaborative project culture by treating underground infrastructure as a shared responsibility.
