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