At the forefront of this evolution is the design-build methodology, which has matured into what industry professionals now recognize as Integrated Project Delivery (IPD).

As a leading Maine design-build contractor with nearly six decades of experience, Ganneston Construction has observed and participated in this transformation firsthand. The shift from conventional design-bid-build processes to more integrated approaches reflects a deeper understanding of project efficiency, risk management, and client satisfaction within the construction industry.

Important takeaway: This evolution isn’t merely about changing contractual relationships—it represents a fundamental reimagining of how construction projects are conceived, planned, and executed in Maine’s unique economic and geographic context.

Understanding Design-Build: The Foundation of Integration

The Traditional Approach vs. Design-Build

For decades, the construction industry operated primarily through the design-bid-build delivery method. This traditional approach separated design and construction into distinct phases with different entities responsible for each:

1. Design Phase: Architects and engineers developed plans and specifications
2. Bid Phase: General contractors submitted competitive bids based on completed documents
3. Build Phase: The selected contractor executed construction according to the plans

While this method provided clear delineation of responsibilities, it often resulted in adversarial relationships, change orders, schedule delays, and budget overruns due to the disconnection between design and construction expertise.

Design-build emerged as an alternative that combines design and construction under a single-source construction responsibility. This approach allows for:

• Overlapping design and construction phases ✓
• Earlier contractor involvement in the design process ✓
• Streamlined communication between all project stakeholders ✓
• Reduced project duration and potential cost savings ✓

The Maine Design-Build Advantage

In Maine’s construction market, design-build offers particular advantages that have contributed to its growing popularity:

• Weather Considerations: Maine’s challenging climate creates short construction seasons. Design-build’s accelerated timeline allows projects to maximize available construction periods.
• Rural Logistics: Many commercial projects in Maine occur in less densely populated areas. Integrated approaches reduce the need for multiple site visits from disconnected teams.
• Regional Expertise: Design-build capitalizes on the specialized knowledge of Maine contractors who understand local materials, building techniques, and code requirements.

Comparing Project Delivery Methods for Maine Commercial Construction

This comparison highlights why more Maine commercial construction projects are moving toward integrated delivery methods that align with our challenging construction environment and the increasing complexity of modern building projects.

Ganneston Construction has leveraged these advantages as it has refined its design-build services over the years, establishing itself as a trusted partner for clients seeking this integrated approach throughout Maine and New Hampshire.

The Evolution to Integrated Project Delivery in Maine

From Design-Build to IPD: A Natural Progression

While design-build represented a significant improvement over traditional methods, integrated project delivery practices take collaboration to the next level. IPD doesn’t replace the design-build approach, but instead builds on its foundation by:

1. Expanding the Integration Circle: IPD brings key subcontractors, suppliers, and even end-users into the planning process from the earliest stages
2. Aligning Incentives: IPD often incorporates shared risk/reward structures that tie team success to project success
3. Emphasizing Lean Principles: IPD adopts waste reduction and continuous improvement methodologies from manufacturing

The progression from design-build to IPD reflects the industry’s recognition that deeper integration leads to better outcomes. As one of Maine’s premier commercial construction firms, Ganneston has embraced this evolution by implementing collaborative construction approach methodologies that bring stakeholders together for enhanced project results.

Key Components of Modern Integrated Project Delivery

• Problems are solved by the team rather than through contractual mechanisms

#3 Shared Risk and Reward

Perhaps the most transformative aspect of IPD is its approach to project risk:

• Contracts may include pain/gain sharing provisions
• Financial incentives align with project goals rather than individual company profits
• Transparent cost structures replace traditional markup models
• Contingencies are managed collectively rather than hidden within individual bids

#4 Technology Integration

Modern integrated project delivery practices often rely heavily on digital tools:

• Cloud-based collaboration platforms enable real-time information sharing
• Virtual design and construction simulates building processes before site work begins
• Digital documentation streamlines approvals and reduces paper waste

Ganneston Construction has invested in many of these technologies and methodologies to provide clients with truly integrated services that represent the cutting edge of the industry.

FAQS

What is Integrated Project Delivery and how does it differ from traditional construction methods?

Integrated Project Delivery (IPD) is a collaborative construction approach that brings together project owners, designers, contractors, and key subcontractors from the earliest stages of a project. Unlike traditional methods where design and construction are separate sequential phases with different teams, IPD creates a unified team working together throughout the project lifecycle.

The key difference lies in alignment of interests: traditional methods often create adversarial relationships where each party focuses on their own financial interests, while IPD establishes shared goals and often includes risk/reward sharing mechanisms that tie team success to project success.

What types of projects benefit most from an integrated approach?

Projects that particularly benefit from integrated delivery include:

• Complex buildings with sophisticated systems (healthcare, laboratories, etc.)

• Projects with tight schedules that require overlapping design and construction

• Renovations where existing conditions create uncertainty

• Buildings with specialized technical requirements

• Projects where owner involvement throughout the process is valuable

• Facilities where long-term performance and operational efficiency are priorities

However, the principles of integration can benefit projects of all types and sizes when applied appropriately.

How does Integrated Project Delivery affect project costs?

IPD can influence project costs in several positive ways:

• Early contractor involvement provides accurate cost information during design

• Collaborative value engineering identifies efficient solutions rather than mere cost-cutting

• Reduced change orders and rework minimize unexpected expenses

• Accelerated schedules may reduce financing and temporary facility costs

• Shared risk/reward structures motivate cost optimization rather than change order maximization

While IPD may require more upfront investment in planning and coordination, this typically results in overall project savings and more predictable final costs.
