Quick Answer

To prevent installation issues when working on a foreign steel structure project, the buyer must verify all drawings before manufacturing begins. In addition to confirming all measurements of the foundation and anchor bolts, the buyer must verify that all components are properly marked and that all bolts and accessories are accounted for. Further, it will be necessary for the buyer to obtain a copy of the erection drawings and review all packages prior to shipment of the materials. Once the shipping containers arrive, it will be the responsibility of the local installation team to be ready for the arrival of the shipping containers. The majority of installation challenges can be avoided prior to the arrival of materials on the construction site.

What Installation Problems Do Overseas Buyers Usually Worry About?

Overseas buyers are frequently concerned about delayed installation, missing components, incorrect component assembly, ambiguous drawings, and mismatched foundations and incur extra labor costs.

A majority of these issues stem from the fact that they didn’t verify the project information in time. While a steel structure building may appear to be quite basic, it actually consists of many different components like columns, beams, purlins, bracing, bolts, roof panels, wall panels, flashing, etc as well as many small accessories.

Why Do Installation Problems Happen in Steel Structure Projects？

Problems during installation arise mainly because the drawing(s), foundation size(s), component label(s), packaging format and site preparation have not been adequately confirmed prior to the delivery of the goods.

Common causes include:

• Drawings are approved too quickly
• Foundation dimensions do not match the anchor bolt layout
• Components are not clearly marked
• Bolts or small accessories are missing
• Roof and wall panel layouts are unclear
• Packing is not arranged according to installation needs
• Local workers do not understand the drawings
• Site conditions are different from the original design

For international projects, buyers are best do not wait for their containers to arrive. The most secure approach is to deal with potential installation risks before the production and shipment.

What Should Buyers Check Before Approving Steel Structure Drawings?

Buyers should ensure the dimensions, column layout, door and window arrangement, foundation layout, roof pitch, material specifications, connection details, and also the snow load requirements in their location are verified before they will approve the steel structure drawings.

Important items include:

• Building length, width, and height
• Column spacing
• Clear interior height
• Door and window positions
• Roof slope and drainage direction
• Gutter and downpipe positions
• Crane, mezzanine, or office requirements
• Roof and wall panel type
• Wind load and snow load
• Steel grade and surface treatment
• Bolt connection details
• Foundation and anchor bolt layout

After the timeline and design drawings have been approved, the factory begins cutting, drilling, welding and painting of the steel components according to the approved drawings.

If the drawings have errors, making changes to them later may mean that you incur added costs and time.

How Can Foundation and Anchor Bolt Errors Delay Installation?

Mistakes made in developing the foundation or anchor bolts may delay installation because the steel columns may not fit the base plates or the bolt positions when made onsite.

It is possible that although the steel frame is manufactured accurately, installation will be delayed if the foundation was not made in accordance with the layout drawing of the anchor bolts during the manufacturing process.

Buyers should confirm:

• Foundation size
• Anchor bolt position
• Anchor bolt spacing
• Column base plate position
• Foundation level
• Concrete curing condition
• Site access for crane and workers

The local team must ensure that the actual foundation is identical to the approved foundation drawing before the steel materials are delivered. If there are any discrepancies between the two, they must be resolved prior to installation.

How Can Buyers Prevent Missing Bolts, Purlins, and Accessories?

Buyers must take precautions against incomplete shipments. The buyer may request a packing list of items to be included in the shipment and verify that all accessory quantities are correct. Additionally, the buyer should ensure that all bolts, purlins, braces, and fasteners as well as trims, gutters and panel accessories are included before the shipment is made.

Small parts are easy to ignore, but they can stop the whole installation.

Buyers should check whether the supplier includes:

• High-strength bolts
• Anchor bolts
• Roof purlins
• Wall purlins
• Bracing rods
• Tie rods
• Connection plates
• Self-drilling screws
• Flashing and trims
• Gutters and downpipes
• Door and window accessories
• Roof and wall panel fasteners

Before shipping, you must request your supplier to send a packing list along with loading images, in order to verify that the primary steel structure is shipped with the remainder of the accessory component supply.

Why Is Component Marking Important for Overseas Installation?

Component marking is critical as the local installation team needs to be able to easily identify the steel columns, beams, purlins and bracing members and connection parts once they arrive on site.

For overseas projects, the installation crew may not be familiar with the details of the project. Thus, by clearly marking each component of the structure, they can match up each item with its corresponding drawing for installation.

Good marking should help workers identify:

• Steel columns
• Steel beams
• Roof purlins
• Wall purlins
• Bracing members
• Connection plates
• Bolts and accessories
• Roof panels and wall panels

If component marking is unclear, workers may spend many hours sorting materials. In worse cases, wrong parts may be installed in the wrong position.

What Installation Drawings Should the Supplier Provide?

Drawings are to be provided by the supplier for installation, anchor bolt layout, steel frame layout, purlin layout, bracing layout, roof & wall panel layout, connection details, component marking list, and packing list.

Useful installation documents include:

• General arrangement drawing
• Anchor bolt layout drawing
• Steel frame installation drawing
• Roof purlin layout
• Wall purlin layout
• Bracing layout
• Roof panel layout
• Wall panel layout
• Door and window layout
• Bolt connection details
• Component marking list
• Packing list

These documents help the local team understand how to assemble the steel structure step by step.

How Does Packing Affect Steel Structure Installation?

Packing affects installation because clearly labeled and well-organized materials are easier to unload, sort, protect, and assemble on site.

Good packing should consider:

• Container loading sequence
• Component size and weight
• Painted surface protection
• Easy unloading on site
• Clear bundle labels
• Matching packing list
• Separate packing for bolts and small accessories
• Protection of roof and wall panels

If material are packed randomly, workers will spend extra time to find the components. Proper packed reduce confusion and protect the steel members in sea transportation.

————————————————————————

What Should Buyers Prepare Before Installation Starts?

Prior to installation, it is necessary to prepare the foundation, as well as lifting equipment, trained personnel, tools and safety equipment, a designated area for unloading materials, storage of materials, etc. along with approved installation drawings.

Important preparation work includes:

• Complete the foundation
• Check anchor bolt dimensions
• Prepare crane or lifting equipment
• Arrange skilled installation workers
• Prepare tools and safety equipment
• Confirm unloading space
• Review installation drawings
• Prepare material storage area
• Plan roof and wall panel installation sequence
• Prepare touch-up paint for scratches

Good site preparation reduces installation delays and prevents material damage after delivery.

What Questions Should Buyers Ask the Supplier Before Shipment?

Buyers need to confirm several things before their products ship, for example, confirming that the drawings are approved, checking component markings, checking the packing list, confirming the presence of bolts/ accessories, and ecking for the provision of installation drawings.

Recommended questions:

• Are the final drawings approved?
• Are all steel components marked?
• Is there a complete packing list?
• Are bolts and accessories included?
• Are installation drawings provided?
• Are roof and wall panel layouts included?
• Are loading photos available?
• How are painted components protected?
• How are small parts packed?
• What should the local installation team prepare?

These questions help buyers know whether the supplier has considered installation, not only production.
