Pre-Engineered Buildings (PEBs) |
Conventional Steel Buildings |
| Structure Weight |
Efficient use of steel = 30 % lighter - tapered build up - large depths in areas of highest stresses = Optimum
Light Gauge Secondary members - low labor cost
|
Standard hot rolled members - inefficient design - Heavier than required !
Heavier secondary members - higher material costs
|
| Design |
Quick Specialized computer analysis & design programs optimize material requirements - Drafting is computerized minimizing errors !
Design, shop and erection drawings are supplied by the manufacturer free of charge
PEB designers are pre-engineering buildings every day of the year resulting in most efficient designs
Ease of coordination allows for lower design and coordination fees
|
Design is made from scratch each time..with fewer design aids…error factors increase…Substantial Engineering and Detailing s required - computer programs require extensive input/output
Extensive consultant time is devoted to design and drafting as well as coordination at significant project costs
Each project is a separate case - engineers need more time to develop designs and details
Design and coordination are complex, extensive and time consuming raising overall design costs
|
| Delivery |
6-8 weeks |
20-26 weeks |
| Foundations |
Simple - Easy construction - Light weight = less cost |
Expensive - Heavy foundation |
| Erection Simplicity |
systems approach = similar systems = learning curve is faster for each consequent project. Steel Buildings Co. provides on site free of charge erection support as well as on site quality control followup |
|
| Erection cost and Time |
Accurate knowledge of time and cost of erection. Erection process is easy, fast with hardly any requirement for equipment |
20 % higher erection costs - difficult to estimate timing and difficult to control schedules |
| Seismic Resistance |
Low weight flexible frames = higher resistance to seismic forces |
Rigid Heavy weight = low performance in seismic zones |
| Overall Price |
As much as 30% Less |
Rigid heavy structures, more expensive |
| Architecture |
Outstanding Architectural Design At low cost combined with wood, concrete, glass, aluminum |
Special design for each project to incorporate architectural appeal increases project timelines and adds much higher costs |
| Sourcing & Coordination |
Buildiing is supplied as one package with erection if required - Turnkey |
Multiple supply sources -requiring logistical coordination and project management effort |
| Cost of Change Orders |
Change orders are easy to respond to with minimal material waste and extra costs |
Substitutes and changes of components is costly and time consuming due to order dates. Redundancies often result in higher cost to the end-user. |
| Building Accessories |
Accessories are standardized parts designed to fit the building - mass produced for economy and are available with the buildings |
Every project requires special design, making the components more expensive and requiring more timely preparation and fabrication affecting your project schedules |
| Future Expansions |
Electronic records are kept indefinitely - future needs are simple to cater to |
Records are difficult to obtain after a long period of time |
| Responsibility |
Single Source of Supply |
Multiple Responsibilities, with the consultant carrying design responsibility |
| Performance |
Buildings designed as a system, allowing for maximum efficiency, precise fit and peak performance with dependable, predictable performance |
Lack of a system design creates greater room for error. Low prediction of how components act together in each unique building. Components may perform differently under different climatic conditions creating unnecessary uncertainty. |
| Global Experience |
Steel Buildings has designed to many international codes and standards around the globe |
Conventional manufacturers are only familiar with local markets and local climatic conditions |
