<br /> Tony:
<br /> T�ianks for getting back to be so quickly. Thank you for Aiscussing the project wRh Tim Tyler,tor as you know,
<br /> The Everett Clinic had requested the meeting with Tim Tyler originaly, but was unable to attend.
<br /> Changing the B Occupancy to Non-conforming , Existinc� I-1.2, appears okay,as bng as there are no changes
<br /> that would need to be made at this tlme based on this revised classification, as you state. However, changing to
<br /> that classification makes the surgery center oxupancy and building type, more out of compliance for purposes
<br /> still unclear, and very unlikely to ever bring into compliance as notac in the issues below.
<br /> The issues you have idenNfied are rrwstly the same we identified in our Due Diligence, November 29, 2000, and
<br /> reviewed with you at our meeting of May 21,2007.
<br /> The issues you identify, appear to be those of what woukl be non-confortning, for which I've commented below:
<br /> 1. A four hour occupancy separation, though required by Table 3-B, would be very unlikety to ever achieve in
<br /> this building unless the second Boor ceilings and he third fiopr partitiuns and finfshes were demolished and rebuilt
<br /> for an albwed rated assemby.
<br /> 2. I believe you are referring to the surgery center being on the third Ibor, and a ramp would be requfred for an
<br /> I-7.2 occupancy to the second floor alley grade level. With a 13'M heTght,lhat would we 130 linear feet of ramp
<br /> (5.2 s^f1"rise ramps), ptus landings, again very unlikely to achieve without taking out hvo bays oF the building due
<br /> to the column/beam spacing less than 23'.
<br /> 3. I-1.2 location at first story, though required by Table 5-B,would be very unlikely to ever achieve in this
<br /> building unless both the upper and lower floors were gutted and rebuiR with surgery center on first floor and
<br /> 9arage on third floor, which would require a vehicular ramp.
<br /> 4. Correcting mixed construction types might be possible in the future, by upgrading to a Type V-1 hour
<br /> building, if the heavy timber construction were protected and the building sprinklered or if the building were
<br /> upgreded to Type IIi-1 hour. i just briefly ren mixed occupancy clac's without a actual detailed check. Both
<br /> upgrades have serious impacts on the existing construction to achieve the rated assemblies, add waier seroice,
<br /> and carry the additional dead loads.
<br /> 5. We recognize there is an existing column in Corridor 330, but is enclosed as part ef an existing wall, hence
<br /> the opening works similar to a door, but there is no door, though we could frame for one. To relocate the column
<br /> ��•ould be a major structural alteration.
<br /> As for plan corrections you are considering two of the three may be possible.
<br /> A. The second Boor Altemate exit corridor is the result of our life safery recommendat!on to the client. 1 t�is was
<br /> identified as an altemate, because the added cost,with possible other corrections, might then approach the i
<br /> threshold of sorinklers and building upgrades,which it triggered,wo�ld be cost prohibftive. �
<br /> B. There is an existing fire alarm system, which is being evaivated, per my understanding this week, by Sonitrol
<br /> and the Fire Department, for the ability to alter, expand, and/or upgrade,without replacing the en!i�system.
<br /> C. Any addition of a sprinkler system, could possibly help the construction Type non-conformance, but dces not
<br /> resolve any of the non-compliant I-1.2 Occupancy location, separation, or egress issues. nddition of sprinklers, �
<br /> would be a very difficult task in the future, due to the need to close all or portions of the facility to accom���;h new
<br /> water service, structural load carrying upgrades, and interior piping.
