Source: Kiewit set to sock City with major change order on rail project

Likely change orders coming on first winning rail bid:


When the Caldwell/Hannemann administration announced a year ago that Kiewit Pacific had been awarded the design-build rail transit contract for the 6.5-mile phase covering Kapolei to Pearl Highlands, they said the bid was $90 million less than estimated.

However, we have just received from a highly reliable source a description of Kiewit's soil testing, which apparently reveals how Kiewit was able to offer the lowest bid on the project and why the cost may be increasing,

    “Based upon the preliminary geotech all indications were that the shortest drilled caisson shafts were 60 to 70 feet deep, and in the Waipahu area there were some that were upwards if 175 to 200 feet, most of which were more in friction than in end point loads. The way Kiewit reduced this amount was by saying that they were going to end-tip grout the caissons, which essentially means that they were going to try to create a bubble at the end of their caissons to try to get more of an end tip bearing and try to catch the shallower boulder layer rather than just friction. This allowed them in theory to reduce the pile lengths by about 25 to 35%, I say in theory as it appears that they are currently working on a large change in conditions change order. I also understand that the test caissons are being installed in within the next few weeks, so the results will end up being very critical to the claim for a change in conditions.”
