I am currently designing a new store front for an existing building. The building contains a 10'-0" wide canopy along the front (code is ASCE 7-10). With regards to GCpi and canopies, would you use GCpi = +/-0.55 or +/-0.18. I would lean towards +/-0.55 as the wind is not allowed to flow over the top of the building as it is being trapped by the canopy.

When making CNC machined parts, mastering tolerances can be challenging. Are general tolerances good enough? When does it make sense to call out for tighter tolerances? Do you need a better understanding of fits, datums, or GD&T? Learn about these topics and more in Xometry's new e-book. Download Now
When designing a metal component, engineers have to consider how susceptible certain alloys are to corrosion in the final productâ€™s operating environment. In a recent study by NACE (National Association of Corrosion Engineers), it was estimated that the direct and indirect costs of corrosion in the United States is approximately 6.2% of the GDP. In 2016, that cost exceeded $1 trillion dollars for the first time. Download Now
With all of the hype around 3D printing, it can be easy to get lost in fascinating, intricate metal parts made with additive manufacturing. These parts, while impressive, are probably dissimilar from many of the parts you currently produce or use. So why invest in metal additive manufacturing? Download Now
Construction was at one time a highly regionalized business. Pragmatic and market forces made it more efficient for even a large, industrial general contractor to focus regionally. But inexorable trends are making it more important for major commercial, civil, engineering and industrial contractors to grow their global footprint.
