Dan,
(1) the $109,215.00 gross estimation adding error of the Paving & Surfacing quantities in original C-M engineers estimate.
(2) the unplanned Subgrade Stabilization quantities in excess of 811.4 cy – 50 cy = 761.4 c.y. (93.4% increase) at $62/c.y. (the renegotiated cost) totaling $47206.80
(3) the missed shallow concrete storm line on Stowers (north of 5th St.) that need to be removed and replace with 10” ductile iron and totaled $7065.00 for 161 LF @ $47.10/LF. This storm line elevation was clearly identifiable in the field by removing grates and survey the inlet elevations in the field.
(4) Overlooked Type G-2 Catch Basin needed at NW corner of 7th and Stowers @ $1200 per each.
Without measuring and calculating the added impacts to the driveways Stowers due to the increased design cross-slope of the road section, I come up with the following total of unanticipated construction costs:
Total = 109,215.00 + 47206.80 + 7065.00 + 1,200 = $164,686.80
One could easily argue that C-M is responsible for 50% of the added cost to construct, as a result of lack of attention to detail in the engineer’s estimate and to gather adequate field information in 30% design phase. Had this information been presented to the City accurately, the City could have make the decision to postponed the construction of Stowers to FY 2015-16.

I need detailed numbers regarding Curran- McLeod. What I understand is that we have about $60,000 in plan and field failure as well as a 3 digit problem with the engineers estimate. I have warned Chad Jacobs and once I provide them him with our details I want to obtain a reimbursement from Curran-McLeod.
