Santa Ana Public Library requested ECS submit <br />a proposal to provide assessment and peer review design consultation services for the building <br />enclosure. <br />1.2 Project Description <br />The project consists of the renovation of an approximately 39,790 square foot historic library building <br />constructed in approximately 1960, with two stories above -grade and one below -grade basement <br />level. The existing exterior enclosure systems consist of marble panels over concrete backup walls, <br />steel windows with single -pane glass, steel -framed storefront with insulated glass units, and built-up <br />asphalt with gravel surface low -slope roofing. The project also includes new steel windows and <br />aluminum -framed storefront and entrance systems. <br />The renovation project includes exterior marble repairs, a new elevator with a new basement elevator <br />pit, north -facing steel curtain wall replacement, historical restoration of steel windows in punched <br />openings, and below -grade basement wall waterproofing repairs. The renovation project is under <br />construction and the demolition phase is nearly complete. Group 4 is in the process of amending <br />design documents to address unforeseen conditions uncovered during initial demolition. <br />Moisture intrusion has been reported before and during construction at multiple locations along the <br />south side of the basement, at the north -facing steel curtain wall and adjacent conditions, at the <br />northeast and northwest corners of the great reading room, and at one second floor location at <br />the south elevations. On March 19, 2024, Mike Huhtala of ECS met with Santa Ana Public Library, <br />PCL, and the Santa Ana Library Services Director on site to review reported moisture intrusion areas. <br />See Appendix I for a summary of approximate moisture intrusion locations. <br />1.3 Documentation Provided <br />ECS was provided with the Permit/ Conform Set Santa Ana Library Renovation drawings and <br />specifications dated August 2, 2024 prepared by Group 4 Architecture Research + Planning, Inc. for <br />reference preparing this proposal. <br />1.4 Proposal Revision History <br />Proposal Revision 01 dated April 22, 2025 addresses the proposal to Santa Ana Public Library. <br />2.0 SCOPE OF SERVICES <br />ECS recommends the following services to evaluate the existing building enclosure performance <br />and reported moisture intrusions, review the renovation project design documents, and offer <br />recommendations for building enclosure and waterproofing system improvements, as <br />appropriate.
