SERVICES

We know the ins and outs of structural steel and exactly how to survey it.

Our team can provide highly accurate as-built documentation for any steel structure. Our crews are based in the San Francisco Bay Area, but travel throughout the Western United States to work on some of the most noteworthy construction projects being built.

PRE-POUR ANCHOR BOLTS

Prior to the anchor bolt foundations being poured, BSI crews field verify the location of the bolts as they relate to the design drawing locations.

Post-pour Anchor Bolts

After the anchor bolt foundations are poured, BSI field verifies the location of the bolts as they relate to the design drawing locations. We deliver a graphic report of our findings indicating the horizontal location of bolt centers to the template centers, along with the complete pattern centers. Vertical data is also provided.

Embed Surveys

Prior to installation, or as a check post installation, BSI crews survey the horizontal and/or vertical location of the embed.

Plumb Surveys

As the columns are erected, we survey the horizontal position of the column. We provide the location to the design grid, the column itself, or both. Clients receive a report with data indicating the top of column location.

Top of Steel/Column Elevation Surveys

As the columns are erected, we survey the vertical position. BSI provides clients the information needed to indicate the top of column elevation including the delta to design elevation for projects.

Edge of Bent Plate

As the bent plate gets laid out, we survey its horizontal location. BSI provides a report indicating the in field location to the design location for the project.

Special Surveys

BSI also provides surveying for layout, bridges, stairs, rackers along with 3D laser scanning. Should you have any other steel construction survey needs, give us a call to discuss.
