31 Wilshire/La Brea Station Excavation Continues Excavation of the La Brea Station box has reached approximately 83% complete 31

32 Wilshire/La Brea Station Excavation When Now through the Fall of 2017 Work hours are 7am to 11pm, and 11pm to 7am as needed What Excavation will occur under the concrete deck, with intrinsically safe equipment certified by the State of California Work includes hanging utilities underneath Wilshire Bl, dewatering system installation, and maintenance of geotechnical instruments and dewatering wells To support excavation, deck openings of the street-deck for the purpose of delivering materials for underground construction may occur periodically, as needed 32

34 Wilshire/La Brea Station Center Opening Now through December 2017 A material handling shaft in the Wilshire Bl center median between Sycamore Av and Orange Dr Regular equipment and truck staging inside the K-rail area The center opening in action 34

35 Wilshire/La Brea Station Center Opening Utilization Thru February 2020 The center opening is a large underground access shaft located behind concrete barriers at Wilshire/Sycamore STS needs to continue to utilize the center opening thru February 2020 to accomplish the following work associated with Wilshire/La Brea station construction: Structural concrete Removal of excavation support system Tunneling equipment and support Mechanical equipment installation This work will occur either with the current work zone in place with limited sign and cone closures, or under almost daily sign and cone closures Current center opening work zone at Wilshire Bl/Sycamore Av 1

36 Wilshire/La Brea Station Center Opening Benefits Why the center opening? Safety: it s the safest method for both the public and the workers to complete the work Traffic: it creates a static traffic pattern, rather than a variety of sign and cone closures that would change daily Noise: it allows for more robust noise mitigation and a better contained work zone than sign and cone closures, also allows the work to be scheduled primarily during daytime hours than with traffic restrictions for sign and cone closures The project is working with the local community and stakeholders near Wilshire/La Brea, detailed presentation on the center opening is online at metro.net/purple 36

37 Jet Grouting Wilshire Bl/Cochran Av Jet Grouting Traffic Control Work zone set up in two center lanes of Wilshire Bl at Cochran Av Work area separated by K-rail and fences Lanes reduced to two lanes each direction at jet grouting locations.
