Every year, Kirksey polls leading general contractors to get a full picture of how construction cost are evolving. This year's numbers show rising costs across every asset type. It's a blow to many who expected construction costs to decline, but while they haven't yet, Kirksey predicts slowing demand should soften the market before the end of 2016.

According to a recent report by CBRE, every major Texas market is experiencing higher-than-average increases in pricing. The sheer demand for construction materials from robust construction activity across all product types, coupled with aggressive infrastructure projects, has created steep cost increases, particularly for cement. 

Kirksey's report explains why pricing hasn't declined in Houston yet, despite the oil-driven slowdown in office development: other markets (regional office, public, healthcare, retail and education) have balanced out the volume. And note, it's uncertain how the surplus in sublease space will affect construction costs for interiors.

Here's Kirksey's breakdown of the latest pricing in Houston:
