Will there be waterproofing on the ground level? It is a big e~ense. A vapor barrier would be <br />~ simpler to handle. Data on the watertable shows it at 11.5 feet. The top of our slap is at l~'4" and we aze <br />dealing with a watertable that could rise or fa11. Curt said at $1.80 per square foot to waterproof, let's <br />make sure we need it. <br />How will we allocate these numbers? Leonazd didn't have an opportunity to talk about this yet with <br />Dave and will get together with him to discuss this. Our e~erience of going down a path and <br />discovering that a critical issue had been left out caused us some delays in the project earlier. We can't <br />afford to do this again. Is there information missing on making a decision that 324 is the way to go? <br />We haven't had a full response from the city yet. What else is needed to make sure we don't repeat <br />past mistakes? The contingent items on this count aze: city concurrence; cost implications; and <br />whether or not we need waterproofing. <br />Dan P. asked about the data on 100 year situations for the watertable to rise above 11 feet. Can <br />Centurywest give us an indication on the watertable. We have high and low data but not extremes. Let's <br />find it out. If there is a risk of a wet basement on the parking level every 100 years that shouldn't be a <br />big deal to live with. Curt said the costs for waterproofing the garage section is more like $200,000. <br />Randy had noticed water in the ground on the Statesman's construction site, close to the building. Did <br />anyone know if they hit ground water or where it came from? Curt wasn't sure what it was, but <br />would check it out. Statesman does have de-watering as part of Pence/Kelly's contract. Leonard <br />mention another issue to look at when considering the two schemes, is the lazger one goes a little deeper <br />and may increase costs. <br />~ It was noted that the Capitol Mall parking structure wasn't waterproofed and they went down two levels. <br />However, the watertable is lower on their site. Maybe we need to prepare for a bad year by pumping out <br />the water. If you don't waterproof with a bathtub, another trea#ment would be to grade the slab, and end <br />up with grates and sumps with pumps so the excess water can be pumped out. What about this <br />technique as a more practical way to handle? Curt said that it would be less costly. Plans have one <br />drain already and they could add a few more. You can't get gravity drainage and will need to pump up. <br />Could talce out of streetscape funds. We do need to put in a new perimeter storm drain around the site <br />and tie across to it. The staff at the city have cleared that the storm line is urban renewal. Another <br />added relocation of a sanitary line will give one element of relief. By taking the storm line across the <br />intersection of Church and Chemeketa and bumping it up to 16" line will take away having to store any <br />runoff on site. The line is not very deep, 6-8 feet on all four streets. <br />R.G. wanted to revisit an issue that Curt brought up eazlier. Who is taking responsibility for meeting <br />with Pence/Kelly on delineating where the costs need to be allocated? Dan P. has the understanding <br />after meeting with the financing group that they need to load costs into the building, and the parking <br />would be separate. It is in the project's best interest to put anything not associated with parking into the <br />structure. The only exception would be the length of column in the parking structure, if not for the <br />parking, the column would not be there. Upper slab to accommodate buses and waterproofing for bus <br />ma11 needs to be put with the bus mall costs. Hatfield Plaza has always been a part of streetscape and <br />not the building. <br />The key objective in our discussions is to end up wit1~ a model that we a11 agree on. We need to lrnow <br />what is shell, what is TI. We need to have written assumptions to support our model so anyone can pick <br />it up and determine what is there. Then, when we make changes, we have a point of reference. Another <br />~ item from the finance meeting is treating the building as one unit and parking as one unit. In allocating <br />costs for the building treat as one piece rather than line items. MMDC will meet with Pence/Kelly and <br />Page 2 of 8 <br />
