Clay: The contractor disturbed much more of the north slope that we intended. The first attached picture shows the ditch prior to construction. The second picture shows the ditch at the beginning of the contractor’s construction. Ditch typical section A-A on the Sheet 2 of the attached plans shows that we designed flow line grading, not north bank reshaping. Our design didn’t need any re-vegetation or stabilization on the north slope. I think it’s reasonable to require the contractor to stabilize the north slope at his own cost, but I don’t think grass will grow this late in the year. How do you feel about wood fiber erosion control blankets?

Subject: RE: Millionaire Ditch - Garver Invoices All: The bid was a lump sum price of $38,000 plus the $6,200 change order for silt removal and “reconstruction” of the third concrete flume. I agree that none of the concrete flumes were “reconstructed” and I also agree that the shotcrete is fine as-is, it will accomplish what it needs to with respect to preventing erosion of the slope. My question is with a lump sum like this, what kind of a price break are we looking for? With respect to stabilization of the north slope, their bid condition 11 states that restoration of turf or vegetation shall be by others … in other words, it looks to me as if stabilization of the north slope was not addressed, and Olden specifically said they will not restore vegetation. We are in late August, what can we put out there that will grow and hold the slope?

Subject: RE: Millionaire Ditch - Garver Invoices Joel, Nancy and I visited the ditch and have a couple of comments: 1. The three concrete flumes were not constructed as shown in the plans. I do not believe this is a problem, but I also do not believe they should be paid for them. It would be fair to remove the concrete pay items and increase the shotcrete pay item to compensate for the area. 2. They need to stabilize the northern bank. I am open to recommendations/solutions. If you have any questions, please let me know. Thanks, Clay Barnett, P.E.

I have attached some photos of the ditch during and after construction. That headwall by Westgrove Road is really something, I had no idea that all that concrete structure was there … amazing! So much of that structure was silted in so badly, with vegetation growing all over it, that I had no idea how much of the channel bottom was concrete. Olden did a really good job, they were in and out in less than a week. All projects should go this well. And you guys should have an interesting task ahead of you with the design work to put that drainage channel in a culvert when we get to that point. Hang on to that survey, it ought to come in handy.
