mechanical consultant is concerned about this. We need to decide if we solve the problem with insulation or heat it mechanically. Clearance is minimal as far as structure and we can insulate between ~he 5' beams. Stairwells: There was a question as to the possible need for larger stairwells. It was decided tl~at, since the largest occupant load is at 515 on the 2nd floor and the 4th floor rises to 687 with conference koom full, there will be plenty of room in the existing stairwells. , Fireproof Files: As long as these files are stationary they do not affect structural needs. Mobyle files do. We may beef up some of the floors, close to the columns, to accommodate future needs. We }~nly need to adjust the rebar in the floor to accommodate the 300 pounds per square ft requirements of the jnobile units. Stationary units only require 125 pounds per square foot. ' Demolition: Staton could get done soon enough to allow us to excavate sooner, environment~l conditions allowing. They look to be ahead of schedule. The last two weeks are cleanup and, based on tl~e schedule, we could begin excavation on the East side in early August. Foundation: The design has been completed, but if we need to revise for a bathtub, it will tak~ about 1 week to change. If we decide to do a de-water design with an underground drainage system, (~RI was recommended. They have requested notification as soon as possible as their schedule is very qight. De- watering during construction is also an issue. Interface may want to design their own underg~ound de- watering during construction, but that may not be a good idea due to environmental considera~tions. If they draw plume during construction, it will impact construction. If they can de-water the sitel without affecting plume then we can do a 24" slab. Drawings: We can't finalize the drawings until the parking structure issue is resolved. Still lopking at getting the results by July 15. Everything ready to put together for finalization once the infor~ation is ~ known. Leonard will send a complete set of current plans to Randy by the end of next week. ' Plans status: Leonard to give update on percentage of completion. ~ Meters: Separate metering will only be done as required for water and electrical. We are sub~netering for water. Electrical submetering is not us~.ally necessary unless you find a tenant that uses an indrdinate amount, then you would have to add one. Each tenant or business that has it's own address wiill be metered by PGE and they will send the bills in the mail. Gas may be needed for the restaurar~t. Day care is usually electric. ' Restaurants: We have received letters of interest from 3 different food related entities. We ~ill need to deal with grease related eachaust which needs to be kept well away from makeup air. There ar~ code requirements for placement. Wind can make a difference but we can't control those types of dhanges. POST TENSION V.S. CONVENTIONAL: A discussion of the merits of Post Tension vs Cbnventional slab floors ensued. Post Tension: We know post tension is the cheapest initial cost. The primary concern is the ~uilding owner's long-term cost and flexibility causes concern. There are new R-meters out now for $~500 which get a sonic picture of cables inside the floor. It is a smal121b machine and you get a digital pr~ntout of what's in the floor. It would cost about $27-30 /hr to locate the cables, but you could train th~ maintenance personnel to use it. You rarely break a cable with this system. ' One problem with Post Tension would be that most contractors assume you have a conventio~al floor and you run the risk of them drilling holes through it without checking. Post Tension slabs are rar~ now without ~ CH2 6/26 Minutes Page 4
