Portable buildings offer a versatile solution for extra storage, office space, or even small living quarters. One of their primary benefits is the ability to be moved from one location to another as your needs change. However, transporting these structures is a complex task that involves more than just a heavy-duty truck.
Whether you are moving a garden shed, a shipping container, or a modular office, successful transport requires thorough preparation and the right equipment. This article explains the essential steps for planning, preparing, and executing a portable building move safely and legally.
Understanding Portable Building Transport
Portable building transport refers to the process of loading, hauling, and unloading prefabricated structures. These buildings are designed to be moved, but they still require specialized handling to prevent structural damage during transit.
Most portable buildings are moved using specialized trailers and trucks. Because of their size and weight, they often fall under specific transport regulations that do not apply to standard cargo.
Types of Buildings That Can Be Transported
Different structures require different transport methods. Understanding what category your building falls into will help you determine the equipment needed.
- Storage Sheds: Typically made of wood, metal, or resin, these are usually the easiest to move due to their smaller footprint.
- Modular Offices: These are often larger and may include electrical or plumbing connections that must be safely disconnected.
- Tiny Homes: These structures are often heavy and require extra care to protect interior finishes and appliances during the move.
- Shipping Containers: These are standard sizes but require heavy-duty cranes or tilt-bed trucks because of their immense weight.
- Portable Cabins: These often have larger dimensions that may require “wide load” permits for road travel.
Step 1: Assessing the Building and Route
Before you book a transport service, you must assess the physical dimensions of the building. Measure the height, width, and length accurately, including any overhangs like eaves or porches.
You also need to evaluate the weight of the structure. If the building was custom-built or modified, it might be heavier than the manufacturer’s original specifications.
Next, survey the route from the current location to the destination. Look for potential obstacles such as low-hanging power lines, narrow bridges, or tight turns that a large trailer might struggle to navigate.
Step 2: Preparing the Building for the Move
Preparation is the most important phase for preventing damage. You should never attempt to move a building while it is full of furniture, equipment, or debris.
Empty the Interior: Remove all loose items from the building. Shifting weight during transport can cause the building to tilt or cause internal damage to walls and floors.
Secure Openings: Ensure all windows and doors are locked and, if necessary, taped or boarded up. Wind pressure during highway travel can easily force doors open or shatter glass.
Disconnect Utilities: If the building is connected to electricity, water, or gas, these must be professionally disconnected. Ensure all pipes and wires are tucked away so they do not snag during the loading process.
Check Structural Integrity: Inspect the base of the building for rot or rust. If the foundation of the structure is weak, it may need to be reinforced with temporary bracing before it can be lifted.
Step 3: Choosing the Right Transport Equipment
The equipment used depends on the size of the building and the accessibility of the site. Professional movers typically use one of three main tools.
Tilt-Bed Trailers
A tilt-bed trailer is the most common tool for moving sheds and small cabins. The trailer bed tilts down to the ground, allowing the building to be winched onto the deck.
This method is efficient because it does not require a separate crane. However, it requires significant space in front of the building for the truck to align itself.
The “Mule” (Motorized Dolly)
A “mule” is a small, motorized device that professional shed movers use to navigate tight spaces. It attaches to one end of the building while wheels are placed under the other end.
The mule allows the operator to maneuver the building around trees, fences, and corners where a truck and trailer cannot fit. This is often the best solution for backyard installations.
Cranes and Flatbeds
For very large buildings or shipping containers, a crane may be necessary. The crane lifts the structure vertically and places it onto a flatbed trailer.
This method is expensive but is sometimes the only option if the building is located behind a wall or in a spot where a trailer cannot reach.
Step 4: Legal Requirements and Permits
Transporting a portable building often qualifies as an “oversize load.” Most states and local municipalities have strict rules regarding the transport of wide or tall structures.
Permits: You may need to apply for a permit from the Department of Transportation (DOT). This permit specifies the route the driver must take and the times of day they are allowed to be on the road.
Pilot Cars: If the building is exceptionally wide (usually over 10 or 12 feet), you may be required to hire escort vehicles with flashing lights to warn other drivers.
Insurance: Ensure the transport company has cargo insurance. This protects you if the building is damaged during transit or if the truck is involved in an accident.
Step 5: Preparing the Destination Site
While the building is in transit, the new site must be ready for immediate installation. A building should never be placed directly on raw soil, as moisture will cause the base to rot or sink.
Leveling: The ground must be perfectly level. Use a laser level or a string level to ensure the site is flat before the building arrives.
Foundation Options: Common foundations include gravel pads, concrete blocks, or poured concrete slabs. A gravel pad is often recommended because it provides excellent drainage.
Access Clearance: Ensure there is a clear path for the delivery truck. Remove any low branches or temporary fencing that might block the entrance to the new site.
Factors That Influence Transport Costs
The cost of moving a portable building can vary significantly based on several factors. Understanding these will help you budget accurately.
- Distance: Most companies charge a base fee plus a rate per mile. Long-distance moves will also incur higher fuel and labor costs.
- Building Size: Larger buildings require more expensive permits and potentially more specialized trailers.
- Accessibility: If the mover has to use a mule or a crane because of tight spaces, the price will increase.
- Site Prep: Some transport companies offer leveling and blocking services for an additional fee.
DIY vs. Professional Transport
While it may be tempting to try and move a small shed with a standard utility trailer, it is generally discouraged. Portable buildings are deceptively heavy and have high centers of gravity.
Professional movers have the specialized winches, hydraulic trailers, and experience to handle the structure without twisting the frame. Hiring a pro also shifts the liability for road safety and structural damage to the transport company.
If you choose the DIY route for a very small structure, ensure your trailer is rated for the weight and that you use heavy-duty ratcheting straps to secure the building to the frame.
Conclusion
Transporting a portable building is a major undertaking that requires precision and the right tools. By taking the time to empty the building, secure the structure, and prepare the destination site, you can ensure a smooth transition to your new location.
Always prioritize safety by checking local permit requirements and hiring experienced professionals when the job exceeds your equipment’s capabilities. With the right approach, your portable building will be ready for use in its new home in no time.
