CONSTRUCTION COST INDEX Q3 2024

Optimism in Non-Residential Construction: Interest Rate Cuts and Stable Material Costs Boost Industry Sentiment

The overall outlook for non-residential construction is optimistic as successive 0.25% cuts to the Fed Funds Interest rate, along with stable construction material costs and a healthy backlog position the industry for growth in project starts by the first half of 2025.

The Denver regional office reported a cost decrease of -0.73% for the quarter, joining other Mortenson offices who saw a drop in costs, including Minneapolis (-0.24%) and Milwaukee (-0.34%). Offices showing slight cost increases include Portland (+0.19%), Seattle (+0.23%), Chicago (+0.40%), and Phoenix (+0.67%). 

Nationally, nonresidential construction costs tracked by the Mortenson Quarterly Cost Index for the 3rd Quarter 2024 remained essentially flat, with only a nominal increase of +0.05%, marking a return to relatively flat cost movement after pre-negotiated labor rate increases pushed Q2 costs up +1.24%.

Construction material costs fell 0.5% in the third quarter and have decreased by 0.8% over the past twelve months as inflation cools and supply chains show some resilience and reliability for most products. While the impact of Hurricanes Helene and Milton put some logistical pressure on materials traveling to Denver projects via the Southeast US, over the road trucking has remained readily available with rates at historic lows. Petroleum costs across the Denver region also softened during the quarter.

For Q3, the top three material packages seeing price decreases reported by the Denver office were Asphalt Paving (-10.4%), Fire Protection Systems (-10.2%), and Reinforcing Steel Material (-4.4%). Trade partners across the Denver region reported increased competition on projects, with competitive bidding beginning to cut into fees.

Nationally trade partner work increased by 0.5% during the third quarter, with plumbing contractors reporting the highest spike in material costs (+6.1%). Labor costs increased by 4.2%, and have increased 5.4% over the last 12 months, contributing in part to a similar year over year cost increase of 3.3% for trade partner work.

While the Dodge Momentum Index, which benchmarks nonresidential construction planning, slipped 4.2% in September and 5.3% in October to close the quarter, economists there remained upbeat on starts increasing in early 2025 as interest rate cuts begin to stimulate projects through the planning process.

Despite the decline (influenced by a normalization in data center planning, which surged in the first half of the year), the index remains at robust levels, said Sarah Martin, associate director of forecasting at Dodge Construction Network, who noted that the index closed the quarter 13% higher than October 2023.

“Owners and developers remain confident in next year’s market conditions,” Martin said, “and the planning queue remains poised to spur stronger construction activity in 2025, following deeper rate cuts by the Fed.”

Although the Associated Builders and Contractors likewise reported a slight decrease in the average construction backlog in October, the year-over-year backlog remains unchanged at 8.4 months. Additionally, contractor confidence in both sales and staffing conditions has improved.

“Like much of the economy, the construction industry remained in some semblance of a holding pattern in October as project owners waited for election outcomes and for interest rates to decline further,” said ABC chief economist Anirban Basu. “Despite this wait-and-see attitude, contractors remain upbeat about the next two quarters.”

In the Denver market, backlog for the third quarter was bolstered by public sector project commitments, and construction in the healthcare sector appears poised for a bounce back to robust activity.

The quarter also marked the end of nearly two decades with the Mortenson Denver office located on 18th Street. In November, Mortenson opened its new 65,000 square foot regional office at 3083 Walnut Street. Mortenson’s self-performed services on the project included concrete, rough carpentry and drywall, and Mortenson also leveraging its controlled off-site manufacturing environment to produce and install prefabricated wall panels.

The Mortenson Construction Cost Index shows essentially flat costs for the 3rd Quarter 2024, continuing a period of negligible or slower cost increases experienced across the 12 months prior to Q2. With continued interest rate cuts and stable material costs, we expect overall spending on non-residential construction to increase as conditions across the next two quarters continue to improve. We recommend customers continue to gauge their market-specific challenge of labor procurement while considering project starts on an opportunistic basis across the remainder of 2024 and into the first quarter of 2025.
