Being a Colorado based home contractor for several decades now, it’s likely that we will be presented with a request to build a second story addition on top of a very old one story home, that will also undergo a major remodel.
Typically a house of this era is built on a ‘raised foundation’, whereby there is a perimeter continuous footing (many times not with rebar in it) and ‘interior’ small concrete piers, supporting posts, girders and the floor joist/subfloor framing.
The raised foundation and framing systems could have been structurally upgraded over the years, but can remain mostly independent from an astute post and beam second story addition design, that we construct, according to the latest seismic codes.
These posts and beams are secured with structural connections, all the way from the roof, down to the new footing pads. These new pads are engineered with high strength concrete and steel reinforcing bars, that connect to the new post framing members, from specific details incorporated into our architectural home plans.
As a Colorado home contractor with an A+ rating, we ensure our Client’s safety, by verifying on the job, that this process is performed correctly. This is accomplished with a licensed Architect or licensed General Contractor from our firm, physically performing on-site observations, verifying that top quality construction methodologies are being implemented in the field.
