Our scope of work was structural steel framing, steel stairs, laser cut guardrails/sunshades, railings and a pretty cool corten water feature, among other miscellaneous steel items. It was logistically a challenging project, but came out great in the end.

Check out our Carnival Wharf project in Long Beach. This retrofit job was successful due to the fact that we detailed with several field surveys and had to adjust around discrepancies between each of them. The steel framing connected between the Wharf Dolphins at a functioning cruise line dock extending across the water. Incredibly, all the steel framing and deck plates hit without any errors thanks to our amazing Ahlborn crew.

Setting 110ft long trusses weighing 10 tons each at our Sierra College gymnasium job in Rocklin, shipped full length. To put the 110ft in perspective, that is approximately 36 yards, the average loss of yards when Nick Bosa sacks Dak Prescott.
