-3- <br />July 16, 1975 <br />didn't scare them off. Tests were taken rather late and they were added <br />to the proposal by addendum, and the drain tile was added under the floor. <br />The soil tests were taken June 26, reports received June 28, and August 5th <br />the contract was let. Contractor's were notified by addendum. <br />Mayor Johnson said he recalled Mr. Walijarvi told Council that for some reason <br />Twin City Testing results were received in his office and got put in a file <br />and didn't get sent to the contractors. <br />Mr. Miller of B -E said Addendum #2 did mention the additional drain tile <br />to be added under the floor but that soil boring test data was not made available <br />to him. <br />Attorney Meyers asked what the customary procedure was in regard to this. <br />Mr. Walijarvi said the contractor by a standard clause is supposed to inspect <br />the area beforehand, but this doesn't really hold him responsible legally. <br />Attorney Meyers wanted to know if the contractor should have asked for soil boring. <br />Mr. Walijarvi said he guessed he didn't supply soil boring information to bidders. <br />Mr. Walijarvi said as the job progressed no one threw up a red flag. Twin <br />City Testing didn't say to watch the soil. He said he had talked to Berghorst <br />and they told him that the Bel Rae had asked them about putting in a basement <br />and Berghorst said don't do it. Mr. Walijarvi asked them why they did the <br />city hall basement without saying anything, why didn't Berghorst tell us. <br />He said the man he talked to at Berghorst had not been involved in the bidding. <br />And, the city had not mentioned anything either. <br />Attorney Meyers asked if this was a responsibility of the owner. <br />Mr. Walijarvi said he wasn't saying that. If the owner is familiar with the <br />area he might say something. Mr. Walijarvi said he errored because he didn't <br />do anything about the flowing sand by using different gradients of sand and gravel. <br />That would have solved it. Twin City Testing says this will work. It does, <br />however, involve money. It will be obvious if it isn't working. We will be <br />able to detect sand from the sump pit and find out if it is coming from <br />perimeter tile and if it is coming from the floor they will have to remove the <br />tile and do something different. He said Twin City Testing is the most <br />knowledgeable firm area wide in this matter. <br />Attorney Meyers asked if another area of omission was in the elevator shaft. <br />Mr. Walijarvi said it wasn't waterproofed to begin with and it was an oversight <br />on his part. He said the first excavation made for the building was bone dry. <br />Along the west wall there was some dampness. The elevator shaft water table <br />was equivalent to the bottom of the footing. After completion it was 2 -1/2" <br />above the finished floor level, a rise of 16 -1/2" from June 26. Observations <br />made at the time indicated that there would be no further problem. It was <br />difficult to perceive the problem we have now. <br />Attorney Meyers asked if the elevator shaft was included in the plans. Mr. <br />Walijarvi said they had alternate bids with or without basement. The elevator <br />was included in the basement plan by law. <br />
