These two items are: requirements for testing and inspection for the <br />existing theater foundations, and what tests and inspections are required for the Lobby and Scene Shop <br />additions given that “as-built” drawings are available. <br />• Chapter 11 – Masonry: no masonry construction was evident on site. No masonry tests are <br />required. <br />• Chapter 12 – Wood: where original construction documents are unavailable, but the date of <br />construction is known and a single material is confirmed, a minimum of 3 samples shall be randomly <br />taken of the existing wood framing for testing at the roof and balcony levels. There is an option for <br />visually observing grade stamps; however, due to the age of the structure, grade stamps are not <br />anticipated to have been used at the time construction was performed. Where tests indicate that more <br />than one material is present, additional tests will be required. In addition to testing for the wood, at <br />least 3 connectors shall be documented for each level (roof and balcony). “As-built” drawings for the <br />Lobby and Scene Shop indicate the grade and mechanical properties of the existing framing. In this <br />case, ASCE 41 requires that at least one location in each story (balcony landing and roof of the Lobby, <br />and mezzanine and roof of the Scene Shop) be randomly verified by observing grade marks or by <br />compliance with wood grading rules. <br />Please note, the EDCR is required to be prepared and submitted to DSA for review and approval prior to <br />the start of any testing. <br />As part of performing an overall structural evaluation, a detailed site survey needs to be made to document <br />the “as-built” conditions of the existing Theater and confirm the “as-built” conditions of the Lobby and <br />Scene Shop additions. The thickness of the various concrete elements will need to be determine along with <br />the size and spacing of all reinforcing – wall vertical and horizontal reinforcing, column vertical reinforcing <br />and tie size and spacing. Lap lengths and splices in reinforcing will also need to be determined. <br />Detailed drawings for the mezzanine framing and those for the roof framing, including the roof truss <br />members, all truss connections, and all connections to the perimeter columns shall be determined as part <br />of the overall structural evaluation of the assembly. <br />In conjunction with architectural requirements, the seismic evaluation of the structure shall account for <br />changes to openings as required by the Building Code. <br /> <br />Page 61 of 454
