In the ever-evolving construction industry, effective design collaboration plays a pivotal role in ensuring project success. Over recent years, the American Institute of Architects (AIA) and the American Institute of Steel Construction (AISC) have joined forces to study various design collaboration techniques used across the construction sector. Their research has uncovered a critical challenge: while terms like “delegated design” and “design assist” are widely used, they often mean different things to different people. These differences can lead to misunderstandings and mismatched expectations among project stakeholders. 

In response, the AIA and AISC have set out to provide a clear framework to define these terms and clarify the roles and responsibilities of those involved. Their goal is to offer design professionals and the broader construction industry concrete definitions and guidelines that can be universally adopted. 

What Is Delegated Design and How Does It Impact Construction?

Delegated design refers to the process where a portion of the design responsibility is formally assigned to a third party—typically the contractor. This allows for more flexibility and efficiency, as contractors may have specialized expertise in certain areas of the design. However, it is crucial that expectations are clear from the outset to avoid confusion and ensure successful collaboration. 

The Role of Design Assist in Modern Construction Projects

Design assist, on the other hand, involves a more collaborative approach. Contractors are brought into the design process early, providing input and expertise that can help shape the overall design. This early involvement helps to resolve potential issues before they escalate, saving time and money while also ensuring the project meets technical and practical requirements. 

Understanding Informal Involvement in Design Collaboration

Informal involvement refers to the less structured form of collaboration between design professionals and contractors. Unlike delegated design or design assist, this type of engagement does not typically involve formal responsibility transfers. Instead, it fosters open communication, idea-sharing, and feedback, which can be valuable in identifying solutions and improving project outcomes. 

The Importance of Clear Expectations in Design Collaboration

Clear and consistent expectations are essential to successful collaboration. As Babette Freund, Executive Vice President of Dave Steel Company, Inc., points out, “This document will help everyone understand and distinguish informal involvement, design assist involvement, and delegation of design work.” When expectations are clearly defined, everyone on the project team knows their role, reducing the risk of errors or miscommunication. 

AIA and AISC’s Role in Defining Design Collaboration Terms

The collaborative efforts between AIA and AISC have produced a two-part paper aimed at better defining these collaboration techniques. Part 1 explores the general principles behind informal involvement, design assist, and delegated design. Part 2, which will be released in the future, will delve deeper into design assist specifically in the context of fabricated structural steel. 

Dr. Charles Carter, President of AISC, expressed enthusiasm for the partnership and the ongoing work: “We are so pleased to have had the opportunity to work with AIA in the development of this document—and look forward to continuing that collaboration on Part 2.” Ken Cobleigh, Managing Director of AIA Contract Documents, echoes this sentiment, stating, “When you work with others to create anything, be it a paper like this or the design of a building, you get the benefit of shared expertise.” 

This paper provides essential guidance on the roles and responsibilities involved in design collaboration, drawing from the collective insights of AIA and AISC. By clarifying these terms and offering practical advice, it aims to enhance the construction industry’s approach to design collaboration.
