Why Construction Projects Are Built on Incomplete Plans (And What It’s Costing the Industry)

Construction projects rarely follow the perfect linear process we imagine.

In reality, land development, design, permitting, and construction often overlap, creating incomplete plans, communication breakdowns, and costly rework.

In this episode of the CONTEC Exec Podcast, Robert Zimmerman sits down with Landon Messal from SiteMarker to unpack one of the biggest challenges in the construction industry: overlapping project phases and the lack of reliable field data.

They explore why projects often start before designs are complete, why incomplete plan sets are still being priced and built, and how poor communication leads to costly change orders.

They also discuss how AI, better data governance, and improved field data collection could transform how projects are built.

• Why construction phases increasingly overlap

• The hidden cost of incomplete plan sets

• Why communication failures create project losses

• Why only 4% of AEC data is organized and accessible

• How AI could reshape decision-making in construction

• The role of leadership and change management in adopting new technology
