Why Design-Build Generates More Change Orders

By: Cameron Page  |  July 20, 2021

 

Commercial construction projects are more advanced than ever and new delivery methods and available technology require the process to be collaborative from start to finish.  We believe Design-Build is becoming more common and therefore worth an exploration on when this delivery method is used, why it leads to more change orders, and how trade partners can better collaborate and reduce risk.


Understanding Design-Build

Historically, construction projects were carried out under a design-bid-build delivery method, where the owner held separate contracts with the architect and the contractor. Design documents were completed, then contractors would bid the scope based on the complete set of drawings and build the project. Any changes to the scope of work were clear and easier to define as extra work because contractors were working with complete drawings. While this method is fairly straightforward, it isn’t without its share of challenges. If a portion of the design is incomplete, incorrect or a change is made, it creates an adversarial relationship between the architect and the contractor as they dispute who is responsible for the additional cost and schedule. 

Owners have begun to move away from this method to more collaborative project delivery types, like design-build. In a design-build delivery, the owner has one contract with an architect-contractor team. In this scenario, both the contractor and the architect work together from the beginning design stages through completion, collaboratively solving problems together to meet the owner’s budget, schedule, and design vision. Design-build was once considered an “alternative” delivery type, but now about half of all projects delivered use this method or a hybrid design-build approach where certain trades are designed underneath the GC like the MEPFS.

Technology Brings More Changes

Design-build brings collaboration and innovation to projects, as teams leverage technology to design and price each scope of work. It’s typical for owners, architects and contractors to collaborate to make dozens of changes to meet the needs of the projects. Construction technology, including 3D design tools like AutoCAD and Revit, make the design process much faster than traditional methods. 

With estimating tools like Assemble, changes are drawn and priced in a matter of hours, if not minutes, making design changes faster to generate and incorporate. The fast-paced nature of the design-build process has made change orders a major financial risk to projects.

Let’s Explore How this Happens

Because the construction industry has shifted to a collaborative design-build process, building sets of plans are typically only schematic and are not finalized when the General Contractor

is brought on board. That’s why the industry has largely moved away from stipulated sum contracts and relies more on GMP (Guaranteed Maximum Price) contracts.

A GMP contract is where the General Contractor guarantees a maximum price based on a list of project assumptions and the current state of design. To do this, General Contractors build in allowances for anticipated costs to complete the project.

These allowances cover design development, undefined material procurement, overtime for a compressed schedule, trade damage, cost escalation, unforeseen site conditions and many other reasons. Allowances act as placeholders and will be swapped out with actual costs through the Change Order process. This delivery type results in numerous change orders that are issued rapidly and frequently throughout the project. 

Because of this, Change Orders today play a more crucial role than ever before. They are the essential process to track changes to each party’s original contract.

Risks Caused by Change Orders

Because General Contractors assume more risk under a design-build delivery method, diligent Change Order tracking is crucial to staying on top of costs and ensuring any changes beyond the initial scope are either covered by an allowance in the GMP or reimbursed by the owner. When the Change Order communication process is inefficient, cumbersome, or just plain sloppy, the financial implications are enormous. Change Orders can easily soar into the millions of dollars, and if there’s a dispute over work completed or who owes whom, the disagreements can escalate into lost wages, lawsuits and financial ruin.

Effective Change Order management can make or break the project budget during design-build delivery, and General Contractors track changes using a Change Order Log, typically in a spreadsheet. It takes multiple employees several hours each week to gather Change Order Requests from subcontractors and manage the Change Order Log for the multiple trades on each project. 

Using spreadsheets and email to gather (more like hunt down!) Change Order Requests from subcontractors leaves General Contractors at risk.  CORs can easily slip through the cracks or get submitted too late for reimbursement, which reduces a GC’s already slim margins. 

How Change Order Communication Reduces these Risks

General Contractors can reduce financial risk by communicating all Change Order cost information in real time in one central location. By transitioning from crowded email inboxes and out-of-date spreadsheets to an organized Change Order Communication platform, contractors can streamline their process and create transparency between all trade partners on the project. 

Change order communication is a win-win for all Subs, GCs and Owners. To learn more about Extracker and see how thousands of contractors are improving their change order process, connect with one of our experts at info@extracker.com or by scheduling a live demo.
