Structural Steel Fabricators

Marina never thought that she would enjoy sitting up there at the cranes. She didn’t really like heights and the place was huge. She never thought she would end up working at the factory at all.

When she started looking for a job first time it was when she started college and needed the money. There were some nice places to work at in the small city, usually it was restaurants and bars for the girls. She found work at a small bakery that was planning on expanding into coffee. She did what she was told and worked at the counter, served the customers first with muffins and scones then coffee came and she learnt about brewing coffee.

Then money simply dried up, her mother said there was nothing they could do, so Marina went to the manager and said she wanted more hours. She never really knew much about investments and funds and did not like college anyway. She wanted to start her real life. So she needed full-time work. But it was too much food somehow.

The town and the factory was getting bigger, too. They were getting into car production and from one day to another a new building was getting erected, a big metal building. After manufacturing assembly was moving here, too, and there was need for more workers, team members for the production line.

The bakery offered deliveries and Marina had her chance to deliver coffee and muffins to the car plant. She felt intimidated when she entered the big new steel building for the first time. Then elation came. Those huge constructions, that great machinery! The space was formidable with a span reaching over 200 feet. She was later told that it was a prefab metal building, built from pre-engineered parts. Marina finally understood how it was erected so fast.

It was the first time in her life she felt so at home! One thing she never got used to at the bakery was those masses of people she had to see every day. And the constant smell of food. Here at the car plant there was hardly so many people. And the vast space! Marina made up her mind for the next day. She went and applied for a position at the factory. She wanted to work there. Where there are nobody to serve only the machinery and cars getting assembled. The big cranes and no smell of food.

In that big industrial steel building she felt totally at peace with herself and the world. She thought that not everybody needs to go to college and especially not her!

One of the major difficulties in any construction schedule is the delay between award of fabrication and production of steel detail drawings for fabrication. Many times the fabricator sub-contract detailing work to steel detailing company after receiving project approval. This process is further delayed by changes in RFI, approval process between the fabricator, detailing company and engineer of record (EoR).

Today Intelligent 3D Modeling software like Tekla Structures, AutoCAD and Revit has changed the way we deal with any fabrication assignment. 3D modeling approach is far more efficient, simple and cost-effective. You can build an intelligent 3D model of structural steel any time – in the earlier stage of conceptual design or in the later phase of the bid drawings become public!

Advantages of Pre-detailing are as below:

• With Pre-detailing the detailer can have direct contact with the EoR – this allows faster redressal of issues as they arise.
• Pre-detailing generates quicker response to the changes in RFIs and can virtually remove the entire approval phase.
• Changes are only handled by the detailer and not the fabricator which results in lower costs.
• Shop detail drawings can be produced in record time.
• With 3D model cost estimates and material take-offs can be generated with few clicks.
• You can have advance bill of material (BoM) ready at the time of bidding or grant.
• Intelligent 3D Modeling helps you detect interference, get clearances for equipment and reduce errors to a large extent. The same 3D model can be reviewed or imported across different software platforms and all construction disciplines
• The erection crew can easily visualize the whole structure in real time something that 2D drawings will never accomplish.
• With pre-detailing steel detailing is possible simultaneously with bid evaluation.
• You can have tentative steel detail drawings and part drawings ready well before the bidding process or award of fabrication, making the project bids very competitive and accurate.
• You can use multiple fabricators to accelerate the project proceedings.
• The Structural engineer of record (EoR) can have more control over the project.

It is important to note that above mentioned advantages helps contractor shrink the steel delivery schedule, improve quality and overall profitability.

Steel buildings have become popular, ranging for commercial to personal uses. They can be used to store horses, equipment which may be from a farm, livestock and other assets. Maintenance and costs are important factors and steel buildings are optimal for all these. Steel buildings are guaranteed structurally sound and will not shift or rot.

Strength and durability of a building is optimal using steel. The cost is determined by the area and by the cost of steel. A standard building size may cost approximately $20 per square foot. This price includes other expenses such as material cost, transportation, construction and whatever else that may be required by contractors.

Steel building prices do not include expensive add on features. This is offered by spending extra to the contractor. Wall insulations and roof utilizations may run into the thousands of dollars. Add on features causes a rise in prices but have long term benefits in the investment. Security and prices may also increase by adding double paned glass windows which increases the appealing look of the building. Addition of gutters may cost along the range of $350-$1000.

Delivery to far places such as overseas may incur extra costs such as shipping expenses. Labour cost is on an hourly basis in steel construction and should be added to the budget. The number of labourers employed increases with complexities of the building chosen for the construction process. Foundation costs are included in proposals by contractors to avoid any surprising costs to the owner. This can cost between $3 and $6 per square feet.

In commercial applications, pre-engineered metal and steel buildings provide cost savings across the board. By implementing these structures in new construction and retrofit projects, developers and property owners are realizing cost reductions from the planning and permit phase through construction and completion. Project managers have found that construction schedules can be noticeably compressed, which translates to reductions in contractor’s overhead, as well as any down time that might affect the tenant of a new or retrofit building.

Typical pre-construction costs that are associated with conventional buildings can be substantial in terms of the project management needed to compile bids and submit items for pricing. Wood famed construction systems demand extensive hours for these activities, and even though concrete block structures reduce the typical pre-construction time somewhat, the pricing of materials and coordination of continuous inspections require project management that is all but eliminated with steel building construction.

In addition, the numerous trades that are involved with conventional wood and concrete block construction require project management in order to finalize contracts for each of the sub contractors. Many of these project management costs are all but eliminated with steel buildings, since the fabrication combines the services of framing, roofing, and window and door installations within the scope of work. By reducing project management, the initial on-site activities can begin once the contracts are complete and the construction plans have been approved.

With any commercial project, generating the construction plans begins with a design that is tailored to suit the intended use of the building. Even the most straightforward structures, such as a service building or storage facility require approved plans with structural and mechanical engineering in order to obtain permits. With conventional systems, the architectural fees and mechanical engineering costs can be extremely costly.

However, fabricators of steel buildings offer a number of pre-approved designs that require no architectural involvement or building department plan check. Plans, plan check and permits for pre-engineered building projects are most often limited to the concrete foundation and the mechanical trades. Initial on-site activities, such as footing excavations and the installation of underground utilities are consistent with the construction of all new commercial buildings, and this remains the case with steel buildings as well. The cost savings in this phase are often realized in the omission of structural pads and extensive footings that are required to support wood framed and concrete block load-bearing walls.

Designs for pre-engineered metal building employ steel I-beams as clear span headers and interior vertical support columns. This system eliminates the need for wood or poured in place concrete support systems that are substantially heavier and more time consuming with regard to installation. In addition, steel web trusses are used as the roof support system, which is far more efficient than wood trusses or a panelized roof in terms of the installation time.

Further, the lighter load ratios of sheet metal siding and metal roofing will reduce the size of the required concrete footing. This translates to a marked reduction in costs that are associated with the concrete footing materials, man-hours, footing excavation and hauling of footing spoils. By eliminating the need for conventional structural systems and those related activities, the construction completion schedule requires less time, and this in turn, reduces the general contractor’s overhead costs.

The process of erecting steel buildings on site is relatively uncomplicated when compared to typical commercial or residential construction. Once the concrete footings and underground stub-ups are in place, the structural components are transported to the site, off-loaded and erected without interruption. Following this assembly, electrical circuits, plumbing connections and air conditioning units can be installed without the need for intensive coordination on the part of the job site supervisor.

Any additional equipment or systems, such as compressors, mechanical lifts or pressurized air lines can be easily installed without inconvenience to those particular vendors. These installations can be clearly defined and coordinated with a minimum of project management, and the contractor’s supervision needed to oversee these activities is often reduced to a portion of the standard involvement.

Finally, off-site activities and costs that are usually associated with the construction of commercial buildings are greatly reduced. Monthly street use permits for roll-off dumpsters are not required since there is very little debris associated with steel building construction. Additional permits for material drops, along with the cost for traffic control, are not required over the complete term of the project. Annoying inconveniences to neighbors, such as the use of pumping equipment to install stucco, and kettles for hot application roofing are eliminated.

Once the steel building components have been shipped to the site, a crane is employed to off-load and place the structural members. In most instances, this activity is completed within a matter of days. Following the erection of the structure, the metal siding and roofing are shipped and installed. This minimum of street use greatly reduces off-site costs, inconveniences and completion of the project. Steel buildings are a cost effective solution for commercial and residential storage, as well as commercial service businesses.
