HOW LONG DOES IT TAKE TO DESIGN AND DELIVER A STEEL BUILDING?
The time it takes to design and deliver a steel building depends steel structure making machine on a number of factors, some of which may be out of human control. From receiving your drawing and specifications to assembling and completing the building, the process is dependent on the complexity and size of building you require and the availability of materials and labor.

DESIGN VARIABLES
The accuracy of the plan or sketch you deliver to the sales consultant impacts the time it takes to create the engineered drawings required for approvals. The more details you can provide and the clearer the picture you have of your desired structure, the easier (and faster) the engineered drawings will come together.
If you and the vendor can reduce the number of times the drawings must be changed before being finalized, you can get through the approval process more quickly.
Include the geometry and layout of the building in your sketch.
Engineered drawings are required for approval of the metal building design and often for the issuance of a building permit.
Create a drawing as close to your vision as possible for the vendor to make an accurate quote.
As with any complex project, precise planning can make a huge difference in production and construction time.
PRODUCTION AND SHIPPING VARIABLES
Once the drawings are approved, materials are gathered for production.
Materials in stock will reduce the time to fabrication.
Custom materials may require slightly more time to obtain.
Standard stock buildings are produced faster than complex or highly customized buildings.
Color selection may also impact time to production - panels are stocked in popular colors, but custom colors require pre-coating before production can begin.
Fabrication begins when the materials are available. The larger and more complex the building, the longer fabrication and packing will take. Anything that is not stock must be created or purchased from an outside vendor, which adds to the production time.
For example, if you are building a restaurant with trademarked colors, the coating and paint colors are created according to the trademarked requirements. Then all panels requiring the coating go through the coating and finishing process before being cut and packed for shipment.
Shipping time depends on the distance from the z purlin roll forming machine manufacturers manufacturer to the building site, the weather, and the roadway to the site. Remote sites far from the main roadways may take longer than a site in a nearby suburb. Weather, particularly in northern winters, can create shipping delays due to ice and snow impacting the passages. Heavy rains and flooding are other elements that can create delays.
CONSTRUCTION VARIABLES
Construction schedules are, of course, affected by harsh weather and environments. Equipment delivery to remote locations may slow work down as can problems with equipment availability. Workers who must travel distances to reach the site are faced with the same weather and roadway issues as other transportation.
Special building codes and requirements can impact your timeline. For example, building in a seismically active area requires changes in design to meet safety controls. Such changes can add to the schedule by requiring additional work or changes to the original plans.
Building size and type also determine the length of time to completion.
Complex, specially designed steel buildings take longer to complete than simple, standard buildings. A rectangular building with a low gable roof and steel panel exterior is one of the fastest to erect.
Climate control requires additional materials such as insulation and ductwork.
Large clear span buildings or very wide structures require added construction time and equipment due to the weight of the rafter members.
More framed openings for doors and windows increases construction time as each must be placed according to design and framed. Also, door and window installation are required for each.
Installation of HVAC equipment will take more time than a simple building that does not require climate control equipment.
Gutters and downspouts are recommended to help channel water away from the structure although the additions take a bit more time.
The metal trim installation also adds to delivery and construction time. Custom trim work will require more time for fabrication.
Even with time added for installation of everything beyond the primary frame, secondary frame, and wall and roof panels, a prefabricated steel building is still faster to erect than one of concrete, rock, or wood. Everything required to assemble the building is delivered. Larger steel buildings are delivered in sections but once the materials reach the site, erection time is quick and easy.
