<br /> s�;r�nco I am reviewing your letter of November 6, 1990 regarding the Mechanica
<br /> $aoRle.:Vosnin�ton
<br /> ceso+ Shafts with concern. You state that efforts to enclose the shafts iave come to a
<br /> Zi1' d6+6� complete tialt due to confusion over design requirements. The type 5 Fire rated
<br /> 2 hour shaft wall as shown on sheet A-6 of the drawings is the U-2 design U-
<br /> FuncfOalr
<br /> ,�me:caea«en�n 505. If M.A. Mortenson and/or their subcont.acror did not understand this
<br /> �:-�u;omFe��,:man�a standard detail the uestion should have been asked through the established
<br /> f.etleriCkRkirkwootlFE � �
<br /> �'�� .���om��eae��eaw D.C.V.R. process. Instead, it appears that the shafts were constructed with
<br /> � ��� s���o,tis:oaor<�: details supplied by subcontractors and or suppliers with no input requested from
<br /> CLchoel E 6atl�.nek NA
<br /> Da+itlLBeroPE this oftice. You also state that the plans and specifications only require tiat
<br /> 1 r,s�onK��:� ^the s stem used meet the requirements for a two hour rated assembly." I beg
<br /> I '�� 17eed lvons PE y
<br /> Ric�ortlAAMCIne11yPE to differ! The general conditions of the contract requires that the building be
<br /> �_' James B�Aossmnn
<br /> ErlingJOlsenGE built in compliance with the drawings and specifications. If there is confusion
<br /> He�banno�e�ca��Fe or doubt regarding clarification, the D.C.V.R. process was eslilblished to
<br /> RobetlLSuntlm
<br /> ��.� provide guidelines and clzrify questions. In regards to Mechanical shafts I o
<br /> I ..�a not recall any questions or D.C.V.R.'s being submitted to clarify any questions.
<br /> You also state that the plans and specifications requirc that the system used meet
<br /> the requirements for a two hour rated assembly. I beg to differ. Plans,
<br /> "'m'� specifications, and generai conditions of thc contract inswct the General
<br /> Contractor, to mal:e sure diat all contract documents meet compliance. If for
<br /> , I�,� some reason the contract documents are unclear to the General Contnctor tlien
<br /> �,,,�,�1 clarification must be requested in writing.
<br /> You also state "that efforts to enclose the mechinical shafts has come to a
<br /> I -;�1 complete halt due to confusion over design requirements and methods." I
<br /> � wonder how you plan to install the heattape and pipe wrap required by contract
<br /> on all pipin� in Uie shafts, if theV are enclosed now. In our phone conversatian
