Every builder knows the thrill of a booming market more projects, more revenue, more opportunities. But as the Construction Scheduling Notebook Essential Planning Tools for on-time delivery has long emphasized, a hot market brings its own set of challenges. When demand outstrips supply, materials grow scarce, subcontractors become difficult to schedule, and project timelines stretch beyond what anyone anticipated. The September 1998 Notebook column from the Journal of Light Construction documented these very pressures during one of the strongest building cycles in recent memory. Today’s builders can learn a great deal from those lessons. This article examines the ripple effects of construction booms, practical strategies for managing shortages, the latest thinking on insulation performance, and the growing importance of indoor air quality in modern building practice.
The Building Boom’s Hidden Costs
When the economy is strong and interest rates are favorable, construction activity surges. That sounds like good news, but the downside arrives quickly: materials become scarce, prices climb, and the labor pool stretches thin. In Houston during the late 1990s, one of the country’s most active construction zones, concrete was in such short supply that some builders were placed on allocation. Max Hoyt, executive vice president of the Greater Houston Builders Association, reported that concrete shipments went first to volume users large home builders and industrial contractors leaving smaller builders waiting for delivery.
Material Shortages and Price Escalation
The concrete shortage in Houston was driven by multiple factors: reduced cement imports from China and Japan, two concrete plants taken offline for EPA-mandated remediation, new plants still under construction, and railway bottlenecks following a railroad company buyout. Builders who once received concrete deliveries within 24 hours found themselves waiting 10 days or more. As Rick Byers of Bycon Construction in Houston noted, ordering ahead only helped if the site was ready, and losing a place in line meant starting the wait over from the beginning.
Insulation was also affected. Government regulations requiring higher R-values in new homes pushed demand beyond what manufacturing plants could supply, despite facilities running at full capacity. In a single month, prices at Owens Corning, CertainTeed, and Johns-Manville rose between 9 and 12 percent, and the market was expected to tighten further. For builders relying on predictable material costs, this kind of volatility can upend even the most carefully prepared estimates.
Permit Delays and Labor Shortages
The surge in construction also slowed building permit processing. In Raleigh, North Carolina, the influx of new residents caused permitting agencies to become overwhelmed. Jim Wahlbrink of the Raleigh/Wake County HBA reported that permit processing stretched to eight to ten weeks. While agencies allocated money to hire new staff, they faced the same labor shortages as the builders themselves a lack of trained, qualified personnel to fill the positions. This created a cascading effect: slow permitting delayed contractor payments, which in turn strained cash flow.
Subcontractor quality also suffered. When demand for subtrades is high, unqualified or inexperienced crews are more likely to be hired. Tony Calvas of Phoenix responded by reducing the number of homes each production manager supervised, giving them more time to inspect work quality. While this approach slowed the schedule and reduced profit margins in the short term, it prevented the far greater costs of rework and liability down the road.
Practical Strategies for Managing Shortages
When forecasters predict years of heavy building activity, long-term supply and demand balances eventually correct themselves. But short-term solutions require aggressive planning and honest communication with clients. The experiences of builders who navigated the late-1990s boom offer concrete strategies that remain relevant today.
Supplier Relationships and Ordering
Ask suppliers to assess their inventory and provide realistic delivery projections for upcoming projects. Order materials as early as possible, and where feasible, stockpile items that store well, such as drywall and insulation. Identify alternate suppliers before a crisis hits so you have options when primary sources run short. Materials like concrete cannot be stockpiled, so ensure the site is fully prepared when delivery is scheduled.
Scheduling and Contract Protections
Extend completion dates to reflect realistic timelines. Explain to clients from the beginning that material shortages and labor constraints may delay their project. Include extension-of-time language in every contract. Consider performing work out of its normal sequence when waiting for specific materials, as Byers did, installing gas lines or other elements while waiting for concrete to arrive.
Key contract clauses to include:
- An escalation clause allowing price adjustments if your costs increase
- Documentation of the pricing used in the initial bid for comparison purposes
- Specification of alternate materials to enable substitutions without requiring client approval delays
- Extension-of-time language tied to material availability and subcontractor scheduling
Subcontractor Backup and Cash Flow Planning
Ask regular subcontractors to commit to upcoming projects early. At the same time, build relationships with backup crews in every subtrade so you are never left without options. If you do not already have backup subs, a busy market is exactly the time to cultivate those relationships. On the financial side, arrange for more frequent payment intervals to counter the cash flow effects of delays. Open a line of credit before it is needed to cover short-term debts for materials ordered in advance.

Insulation Performance in the Real World
A field study conducted by the National Association of Home Builders Research Center on 26 new homes in the Baltimore-Washington metropolitan area produced findings that upended some long-held assumptions about insulation performance. The study compared fiberglass batts with spray-applied cellulose, blown-in blankets (BIBs), and Icynene foam-in-place insulation, focusing not just on thermal performance but on real-world installed cost, installation time, workmanship, and air leakage.
Fiberglass Batts with Air Sealing
Previously, spray-applied cellulose, BIBs, and Icynene were considered superior to fiberglass batts for blocking air movement. But the NAHB study showed that when fiberglass batts were combined with a comprehensive air-sealing package, air leakage rates compared favorably with the other materials. The air-sealing package included caulking or gluing all double studs and plates, applying foundation sill sealer, chinking windows with fiberglass, and installing air-barrier tape at windows.
The study found that the installed cost of alternatives was significantly higher than fiberglass batts for achieving an R-13 wall system:
| Insulation Type | Cost Premium vs. Fiberglass Batts | Installation Time Factor |
|---|---|---|
| Fiberglass Batts (with air sealing) | Baseline | 1x |
| Spray-Applied Cellulose | 71% more | Up to 2.5x longer |
| Blown-In Blankets (BIBs) | 105% more | Up to 2.5x longer |
| Icynene Foam | 174% more | Up to 2.5x longer |
Once the effect of the air-sealing package was accounted for, spray cellulose and BIBs did not significantly reduce envelope leakage compared to fiberglass batts. Icynene offered some advantage in air leakage reduction, but the payback for the higher initial cost was estimated at more than 20 years. The study also noted that non-batt materials exhibited fewer installed defects compared with average-quality batt installations. However, when batt installers knew their work would be evaluated and tested, workmanship quality improved dramatically.
Limitations and Caveats
The study considered only walls, and project leader Matt Pesce noted that non-batt materials might offer clearer benefits when installed in ceilings, particularly at wall-ceiling intersections where air leakage is most common. For builders deciding between insulation types, the findings suggest that a well-executed fiberglass batt installation with proper air sealing can deliver comparable performance at a substantially lower cost, but only when workmanship standards are high.

Indoor Air Quality and Builder Liability
As buildings become tighter and more energy-efficient, indoor air quality has emerged as a serious concern. The EPA estimates that 30 percent of the approximately 4.5 million office and public buildings in the United States have indoor air quality problems, putting an estimated 100 million Americans at risk. Adults spend about 90 percent of their time indoors, and up to 60 percent of that time in the workplace. The irony is that the energy-efficient building practices introduced in response to the 1970s energy crisis helped create the problem by reducing natural infiltration without adequately compensating with mechanical ventilation.
Common IAQ Risk Factors
The most frequent causes of indoor air quality problems in new construction include:
- Inadequate code requirements for ventilation that have not kept pace with reduced natural infiltration
- Increased use of manufactured products that off-gas volatile organic compounds
- Improper operation and maintenance of HVAC equipment
- Moisture intrusion from inside or outside the building envelope
- Construction debris left behind that continues to emit pollutants
Protecting Your Business with IAQ Practices
Waiting for an illness or a lawsuit is not a strategy. James Neet, an attorney specializing in IAQ law, recommends the following proactive measures for builders and contractors:
- Run the HVAC system to confirm it is in good working order. If the system is more than five years old, have an HVAC contractor evaluate it before occupancy.
- Include a disclaimer in your contract that excludes responsibility for the operability of the HVAC system, moisture intrusion from outside sources, and modifications made by others after your work is complete.
- Establish written procedures for investigating complaints. Respond to all calls within 24 hours; for life-safety issues, respond immediately and take corrective steps.
- Document every complaint and schedule an investigation within five working days. Set a firm deadline to resolve the problem and stick to it.
- Prevent IAQ problems during construction by avoiding materials containing formaldehyde, lead, asbestos, CFCs, or mercury. Keep debris cleaned up daily to avoid leaving pollutants in the completed building.
Sample Contract Language
Including an IAQ clause in your contract can help limit liability. A sample clause might state that the building has been constructed using generally accepted principles and materials that should not contribute to IAQ problems under normal conditions, and that the contractor is not responsible for problems caused by improper operation or maintenance, moisture intrusion, lack of maintenance, modifications by others, or manufacturer defects.

The lessons from the 1998 construction boom are as relevant today as they were then. Material shortages, labor constraints, and the push for tighter, more energy-efficient buildings all demand that builders stay informed, plan aggressively, and protect themselves with sound contracts and careful workmanship. Whether you are selecting insulation, managing subcontractors, or addressing indoor air quality, the key is to anticipate the challenges before they arrive on your job site and to have a plan ready when they do.
