Winter Site Prep: 5 Steps to Avoid Costly Delivery Delays

Winter building in the Midwest and South is a game of logistics. Between frozen ground, unpredictable ice, and mud-slicked access roads, a truss delivery that takes 30 minutes in July can easily turn into a multi-hour ordeal in January.

At Superior Building Concepts (SBCKY), we ship nationwide year-round. We’ve found that the difference between a project that stays on schedule and one that stalls often comes down to 30 minutes of site prep before our truck arrives.

Here is your winter checklist for a seamless truss delivery, based on BCSI (Building Component Safety Information) industry standards.

1. The "Path of Least Resistance" (Access Roads)

A fully loaded truss trailer can weigh up to 80,000 lbs and has a wide turning radius. In winter, soft ground or hidden ice can cause a truck to slide or become "frame-hung" instantly.

• Clear the Ice: Ensure the entry path and the unloading zone are salted or sanded. Per DOT safety guidelines, drivers may abort a delivery if site conditions pose an immediate risk of property damage or injury.

• Identify "Soft Spots": If the ground isn't fully frozen, it will likely be mud. Consider laying down crane mats or crushed stone in high-traffic areas to prevent the delivery truck or your crane from sinking.

2. Prepare the "Sleepers" (Dunnage)

Trusses should never be dropped directly into snow or standing water. According to the American Wood Council, prolonged exposure to standing moisture can lead to fungal growth and lumber "crowning" (warping).

• Elevate the Stack: Have 2x4 or 4x4 "sleepers" (dunnage) ready. These must be placed on level ground to keep the trusses at least 4–6 inches off the surface to allow for air circulation.

• Level is Critical: If your dunnage is uneven, the trusses can "rack" or warp under their own weight. This makes them significantly harder to plumb and level once they are being set on the roof.

3. Plan for the "Sail Effect" (Wind Safety)

Winter storms often bring high gusts. Because trusses have a large surface area, they act like a giant sail during the lift.

• The 20 MPH Threshold: While specific crane limits vary, OSHA 1926.1412 and industry best practices suggest that unloading and setting trusses becomes significantly more hazardous when wind gusts exceed 20 mph.

• Staging Area: If it’s a windy day, designate an unloading zone shielded by the structure itself or a treeline to prevent the trusses from catching the wind during the "pick."

4. Strategic Tarping: Let it Breathe

If you aren't setting the trusses the same day they arrive, you must protect them—but doing it wrong can trap moisture and cause wood degradation.

• Avoid the "Greenhouse Effect": Do not wrap trusses airtight in plastic. This traps ground moisture inside, which, combined with temperature fluctuations, can lead to mold and connector plate corrosion.

• The Right Way: Cover the top and sides with a breathable tarp, but leave the bottom open for airflow. This keeps the snow off while allowing moisture to escape.

5. Hardware & Tool Prep

Nothing slows down a winter set like a crew searching for frozen hardware or trying to nail through ice.

• Stage Your Hangers: Keep your hurricane ties, hangers, and nails in a heated trailer or a dry gang box. Cold-shattered plastic or frozen nail strips can cause equipment jams.

• Clear the Plates: Before the crane arrives, check the truss connector plates. If ice is frozen into the teeth of the plate, it can prevent the proper seating of bracing or sheathing, compromising the structural connection.
