More Pine Forest Steps Fail

In case you needed any more evidence of the slipshod way the “exercise stairs” at Hillcrest Park were built, I offer in evidence some images taken by the FFFF Construction Field Documentation Team (CFDT) that has been awfully busy lately examining the many failures at the “Pine Forest Stairs” to nowhere.

Here is what the foundations are supposed to look like:

Here is what happened at one location. The top of the caisson was too high and had to be broken out to accommodate a post or cross beam supporting the stair stringer. Unfortunately the rebar in the caisson has been exposed to rust away and eventually spall the concrete.

Here’s a location where a large chunk of the caisson has mysteriously broken off. Here there is no reinforcing steel in sight.

And finally, here’s an example of what can happen when you decide to sink a big 6″x 6″ wood post into concrete:

Apparently many of the caissons are already cracking just like this one. Are these structures even safe? Will our common seismic events cause serious problems? I’m not privy to those answers, but I can tell you that there’s no way I’m getting on those things.

And just for fun, note that the contractor reworked the top the caisson to get water to run off. This sloppy effort is going to flake off – exposing the post to a permanent puddle.

It’s hard to believe that “professionals” inside and outside of City Hall were extremely well paid to oversee this hodgepodge of construction horrors, but there you have it. $1.6 million dollars and this is the best Fullerton can do.


Who Was in Charge?

During our series on the ill-fated, $1.6 million dollar “exercise stairs” in Hillcrest Park, some of our Friends correctly noted the problem of the wood support posts that had been poured into the concrete caissons that hold the whole structure up. Obviously, something went wrong. Notice how none of the posts are centered on the caissons, and some are barely two inches from the outside of the concrete, leading me to wonder how they managed to fit a rebar reinforcement inside the caisson.

Something didn’t quite line up…

From the project drawings, here is how the caisson and post are supposed to be aligned. The post centers on the caisson with 4 rebars equally spaced around it. Please notice the 3″ minimum clearance from the rebar to the outside of the concrete.

Clearly the footings and posts were built incorrectly. Obviously the caissons holes were drilled in the wrong places – and the construction manager must have agreed to let this pass. I guess we’ll just have to wait to see what happens. If the footings crack them may have to be replaced – and they weren’t built to be replaced.

This whole mess made me wonder about why the posts were sunk into the concrete in the first place – a very odd situation given that the expansion and contraction of the posts, when wet, could lead to potential concrete cracking and spalling, especially when the post is near the outer rim of the caisson.

It turns out I wasn’t alone. Here is a string of e-mails from the contractor, construction manager, and the architect discussing the redesign of the caissons and posts to a hardware connection – a solution that would make the replacement of the posts significantly easier. The contractor was willing to do this and add the necessary cross bracing at no cost to the City.

Request denied.

I wonder what will happen when the concrete caissons crack, or when the posts rot out. The architect seems to think the posts will outlast the rest of the rickety framing. I wonder which will go first.
