SELECTED CMGC Project Delivery Method

1. Maintain operations at Los Angeles Union Station, largest multi-modal transit terminal in Southern California serving over 100,000 passengers every week day

2. Fixed Budget – Due to the financial constraint of a $950 millionfunding for the entire project, there is very limited ability to absorb cost overruns.

a) Maximize cost and schedule savings with early engagement of the Contractor (constructability review, value engineering analysis, bottom-up construction estimate, risk analysis and construction schedule) at every design submittal.

b) Minimize change orders during construction.

c) Minimize third party delays with flexible phasing plan based on GC construction schedule.

APPROACH TO 55 HOUR LANE CLOSURE FOR CONSTRUCTION OF RUN-THROUGH TRACK BRIDGEArea 3 – Requires Joint Approval by Caltrans & LADOT

Proposed Closure (Year 2022)a. 55 Hours on Weekend

b. Closure Duration: From Friday 10 PM to Monday 5 AM

c. 5 Weekend Closure in NB US-101 and 5 Weekend Closure in SB US-101

d. Only 1 direction of US-101 will be closed on a particular weekend

Executive Summarya. Tested three Diversion Patterns (60/40, 70/30, 100/0)

b. Tested two traffic levels (Actual at 5600 - 5800 vph and Max. Theoretical)

• Not a substantial difference

• Year 2022 Projections for Saturday Peak Hours, NB and SB

• Some freeway segments hit capacity at 70/30

• NB closure more complex

46


46

TMP LOS Results

Using 70-30 split for NB and SB closure and existing volumes:

a. 2 Freeway segments impacted

b. 5 intersections impacted

47


47

Proposed Recommendationsa. Maximum diversion is a 70/30

b. SB US 101 closure should stay open to Los Angeles Street

c. NB US 101 could close at I-5/I-10 Interchange with support from diversion to I-710

d. Significant Regional SB diversion needed for SB closure

e. I-110/I-10 ramps will need support

f. Significant public information campaign will be needed

Next Steps a. Work with Caltrans and LADOT to receive concurrence by August 2020

b. Work with CMGC on preparing Transportation Management Plan (TMP) and construction phasing

Benefits of BIM

Implementation of Building InformationModeling (BIM)

Risk Reduction

a. Find Coordination and Construction phasing issues in office rather than in field

Better Inform and Support Cost Estimation

a. Quantities can be dynamically pulled from models and trended over the design lifecycle

Automation of Plan Production from Model

a. Allow multiple alternative analysis when compared to traditional 2D plan production due to dynamic and parametric setup

Enhanced Coordination

a. BIM Models provide effective ways to communicate and coordinate design among multiple stakeholders
