The purpose of this letter is to report the observed damaged to the exisHng structure, and to provide conshucHon details(Pigums 1 through 5) for temporarily shoring the existing structure as required to replace the damaged structural members. The rooE over the existing pool building is framed with six,exposed,arched,glulam bcams spanning in the north-souUi direc6on. At the south exterior wall,each beam bears on a pipe column buried in a CMU wall. The beams span conHnuously over the south exterior wall and connect to a concrete buttress located outside[he building. The north end of each glulam beam frames in to an interior CMU wall. The remainder of the roof framing consists of 2x6 T&G decking over bx14 purlins spanning behveen the glulam beams. The exterior walls consist of CMU,contmte stem walls,and plas6c wall panels. A large porHon of the east exterior wall consists of the plastic wall panels. The panels are held in place by vertical aluminum window mullions at approximately 4-foot tenters. Each mullion is attached to an exterior,exposed, tube steel column designed to resist horizontal wind Ioads. A glulam beam spans over the top of these tube sleel columns. The tube steel columns are attached lo the underside of the beam and bear on top of a concrete stem wall. The follo«�ing conditions were nomd: • The exposed exterior portion of each glulam beam appears to be cracking, delaminaling, and/or rotfing in several locations. The damage is eslensive in several Ueams and may compromise their structural integrity. • The glulam beam at the east end of the pool building appears to be cracked,rotted,and delaminating in various locations along its entire length. • At the east end of the pool building,several of the tube steel columns below the glulam beam appear to be buckling and bowing towards the east. The connecHon of one of the aluminum mullions�o the tube steel column has partially failed. • The base plate for Uie buried pipe column in the southeast wmer of the Uuilding is exposed on the east side and does not appear to be bearing fully on the concrete stem wall. • Portions of Uo[h tlie south and east exterior CMU��alls appear to be cracked,especially in areas where the Uuried pipe columns are located. _,�� <<� �._� � , , __� � . �,��o� f `�L3
