This year, exceptionally high price increases of construction materials have caused serious problems for the construction industry. A major factor is the current economic and construction boom occurring in China. China is experiencing rapid growth and, with it, tremendous construction activity which is creating shortages in the US and throughout the world.


Basic economics tell us that, in an open marketplace, prices will rise when demand increases or when supply decreases. Demand is increasing exponentially in China due in part to a construction boom resulting from the country’s economic revolution, preparations for the 2008 Olympic Games, construction of the Three Gorges Dam, and the construction of thousands of highways throughout the country. Demand is also significantly higher in the US due to a rise in construction activity, related in part to new home construction. Some of the highest price increases have occurred with steel, lumber and plywood, while cement has been in short supply. The following graph shows the extent of construction material price inflation over the past twelve months:


The construction industry has seen the demand for steel increase and the supply decrease simultaneously. All types of steel have increased in price over the past twelve months. Reinforcing bar has risen by 45.2%, while structural steel has risen by 25.7%.

China is currently consuming about 25% of the world’s steel supply. Since China is a major player in the steel production market, it can redirect previously exported steel to fill its own domestic demand for the material, reducing the material’s availability on the open market. A similar situation is occurring in India, where some suppliers have halted exports in order to meet domestic material demands.

While demand for steel has risen greatly, the shortage of coke, used in steel manufacturing, has reduced US steel production. Other factors such as high energy costs, high transportation costs resulting from increased fuel costs, the weak value of the US dollar, and the consolidation of steel manufacturers are all contributing to the increased steel prices. Delivery delays have resulted from international shipping lanes being stretched to capacity.

Lumber and Plywood

The prices for lumber and plywood have also risen dramatically over the past twelve months, mainly due to increased residential construction activity in the US. Low interest rates have spurred much of this new residential construction. Lumber has risen an average of 25.8% while plywood has risen an average of 21.5%. Since the start of this year’s hurricane season, repair and reconstruction work necessitated by hurricane and flood damage has further driven up lumber prices. These high prices will likely be sustained over the short term while the massive reconstruction efforts are progressing.


While cement prices have not risen as significantly as other materials’ prices, the shortage of cement has been a problem, particularly this past summer. Concrete mixing companies could not produce concrete fast enough to keep up with demand. The shortage led to countless project delays and disruptions.

In 2003, 20% of the US demand for cement was fulfilled by imports. The US has anti-dumping laws and very high tariffs against Mexico, making imports from that country cost prohibitive. The length of time to import materials from overseas, as opposed to receiving materials from Mexico, is much greater, as it takes weeks rather than days to receive a shipment. The resulting delays can be hard on contractors who need to adhere to a tight schedule. In addition, because of high activity in Asian markets, particularly in China, freightliners are making the majority of shipments to that part of the world rather than to the US.

China is currently consuming approximately 40% of the world’s cement supply. The country’s exceptionally high demand for concrete has allowed it to outbid US buyers on the world market, further reducing availability to the US.

Challenging Times for Contractors

Many of today’s construction contracts are lump sum or unit price contracts, which can take a year or more to complete. Because these contracts are typically based on material prices estimated at the beginning of the project, the contractor can be adversely affected when material prices surge unexpectedly.

The contractor must often absorb the increased cost of construction materials. Considering the increased cost of materials and the fact that numerous projects today have slim profit margins, many contractors either make no profit or stand to lose money on a given project.

While steel prices have leveled out recently, albeit at a high level, there is always the possibility they could increase again. Even though China’s government has instituted measures to slow the dangerously rapid growth of their economy, the overall demand for construction materials is still very high.

In addition to rising prices, another major problem is the delayed delivery of materials to contractors due to material shortages. Material delivery delays are generally beyond the control of the contractors, and they can delay the entire project. Such delays can put contractors at risk of liquidated damages due to missed project deadlines.

Possible Solutions

The following list highlights possible solutions to the increased material prices and material shortages dilemma:

  • Incorporate price protection clauses into contracts (apply bid qualifications).
  • Lock in on material prices.
  • Buy materials early in the project to ensure availability.
  • Delay the project until prices decrease.
  • Work together with other builders and contractors to obtain group discounts on material purchases.
  • Employ value engineering to help reduce costs.
  • Renegotiate contracts to accommodate price increases and/or industry shortages.
  • Purchase materials in bulk to receive discounts.
  • Consider renovating an existing building as opposed to building a new structure.
  • Maintain a good relationship with material suppliers.

Looking to the Near Future

Increased material costs may eventually cause a decrease in residential construction and are already increasing the price of new homes. This, in turn, could negatively impact new home sales, as home buyers are priced out of the market.

The market may, however, experience some relief in the near future. The following factors may alleviate the current situation:

  • Rising interest rates may slow construction enough for cement and steel production to catch up, thus stabilizing prices and supplies.
  • Construction rates will decrease as winter approaches.
  • The measures being taken by the Chinese government may slow down its economic growth and in turn reduce some of the material price increases being experienced throughout the world.


Contractors must be careful to protect their own interests in a market that is shifting an increased amount of risk onto contractors. Protection from material price increases is just one of the considerations contractors must keep in mind. Owners must also be aware that current material shortages can delay projects and increase their costs.
