10 Wilshire/La Brea Schedule *As of January 2017, subject to change Activity Name Q2Q3Q4Q1Q2Q3Q4Q1 Q2 Q3 Q4Q1Q2Q3 Q4Q1Q2Q3Q4Q1Q2Q3Q4Q1Q2Q3Q4Q1Q2Q3Q4Q1Q2Q3Q4Q1Q2Q3Q4 ADVANCED UTILITY RELOCATION PILING DECKING STATION EXCAVATION STATION CONSTRUCTION TUNNELING TESTING REVENUE SERVICE 10

11 La Brea Station La Brea Staging Yards Staging Yard Activities and Equipment Yard usage: 7am-11pm, (11pm-7am as needed) Sound wall is ft high Maintenance of equipment Deliveries of materials Removal of excavated soil Mitigations Must comply with City of Los Angeles noise requirements Noise Control Signage Low Impact Back up alarms Acoustical Insulation Metro 5 Step Noise Plan La Brea station, west of Sycamore Av, looking east Installing dewatering system, La Brea North Shaft 12

12 Wilshire/La Brea Work Zone Traffic Control *Dates subject to change This work zone advances the following: Wilshire/La Brea station excavation Utility hanging from the deck Dewatering system installation Maintenance of geotechnical instruments and dewatering wells Restoration of street and sidewalk In place through February 2017 * Work to support excavation from closure on Wilsire Bl in progress 13

13 Deck Openings What: Deck openings are openings of the street-deck for the purpose of delivering materials for underground construction. Deck openings will be done at locations of the deck that are designed to open and close. Deck openings will occur periodically, as needed Deck panels are 8 ft by 14 ft When: Following La Brea decking, late 2016 Throughout the duration of the project How: Off-peak hours (Mon. Fri., 9am-3:30pm, 7pm-6am) and Sat. and Sun. Traffic reduced to one lane each direction Example of a deck opening from underneath the deck 14

14 Wilshire/La Brea Station Center Opening Construction Concept What Establish a material handling shaft in the Wilshire Bl center median between Sycamore Av and Orange Dr, just east of La Brea Av in lieu of multiple intermittent closures and panel openings during excavation Wilshire Bl remains two lanes in each direction between La Brea Av and Mansfield Av Left turns open on Wilshire Bl at La Brea Av and Detroit St in both directions Center opening will resemble jet grouting enclosure When Proposed dates February 2017 thru December 2017 How The work zone would be established using k-rail, fencing and sound blankets Cross-section of center opening being used for excavation 14 14

15 Wilshire/La Brea Station Center Opening Construction Concept Proposed Benefits Handling material in and out of the 1,000 ft station during construction Safest method to accomplish work under deck Limits lane reductions for deck openings, leaving a more consistent traffic pattern More robust noise mitigation for this method rather than for lane closures Assists traffic flow of hauling and decentralizes hauling from the La Brea staging yards; places more truck traffic on Wilshire Bl Expedites station excavation and concrete work Center opening work zone on Wilshire Bl between Sycamore Av and Mansfield Av, Wilshire Bl two lanes in each direction 15

16 Wilshire/La Brea Station Excavation Now through the Fall of 2017 Work hours are 7am-11pm, 11pm-7am as needed Excavation will occur under the concrete deck, with intrinsically safe equipment certified by the State of California Inspector examining welds on power duct hangers 16

17 Jet Grouting Overview Jet grouting is a construction process that uses highpressure air and grout to create a deep soil-concrete block Jet grouting reinforces and strengthens the soil with concrete to support tunneling and cross-passage construction Locations Jet grouting will occur at 16 cross passage locations along Wilshire Bl between La Cienega Bl and Western Av There will be no more than three jet-grouting operations performed at one time (this can make traffic control simpler and safer), in consultation with LADOT Jet grouting requires approximately 8 to 12 weeks at each location, due to traffic control and installation of geotechnical instrumentation for future tunneling Work hours Mon. thru Fri. 7am-9pm, Sat. and Sun. 8am- 6pm Workers pothole to find utilities before jet grouting at Wilshire Bl near Windsor Bl, and workers move k-rail near Windsor Bl 17 17

18 Jet Grouting *Dates and work activities subject to change Schedule Location Wilshire Bl between Rossmore Av and Lucerne Bl Wilshire Bl between Arden Bl and Muirfield Rd Wilshire Bl between Plymouth Bl and Windsor Bl Status In process In process In process Wilshire Bl between Norton Av and Wilton Pl Anticipated February 2017 Wilshire Bl between Gramercy Pl and St. Andrews Pl Anticipated February 2017 *Construction notices will be sent and outreach will be conducted for each location 18 18

19 Jet Grouting Activities and Layout Work Activities Potholing, street level excavation, vertical drilling, trucking, cement silos, pumps, generators Layout Concrete barriers placed on the middle lanes of Wilshire Bl Lanes reduced to two lanes each direction at jet grouting locations Bus stops will be temporarily relocated as required Wilshire BRT lane not enforced in these areas during jet grouting Intermittent material deliveries during off peak hours 19

20 Scientists Find Mastodon Fossil Found at Future La Brea Station Workers discovered what appears to be mastodon or mammoth tusks and teeth on before Thanksgiving 2016 Cogstone paleontologists were onsite (they monitor all excavation) to identify and preserve fossils revealed by construction Cogstone identified a three-foot section of tusk and tooth fragments 15 feet below the surface After Thanksgiving, a partial skull with tusks of a possibly much younger mammoth or mastodon was discovered Other fossils may be found at other stations Paleontologists reveal the tusk and tooth fragments of an ancient ancestor of the modern elephant 20 20
