STATEMENT OF WORK PART 1 - GENERAL 1.1 DESCRIPTION

A. The Los Angeles County Metropolitan Transportation Authority (referred hereinafter as Metro) is seeking a qualified Design/Build (D/B) Contractor to design and construct a new west entrance connecting the existing Metro Red Line (MRL) North Hollywood station to the Metro Orange Line (MOL) North Hollywood station at 5273 Lankershim Blvd., North Hollywood, CA 91601. This is a Lump Sum project and the Contractor shall include all services, final design, labor, materials, equipment, appurtenances, transportation, and related cost necessary to complete the work. Location and limits of the work for the MRL North Hollywood station west entrance project are shown on the attached Contract Document. All construction of the project shall conform to the latest edition of all applicable regulatory codes, Metro Design Criteria, Metro Standard and Directive Drawings, including sustainability requirements, and City of Los Angeles Design Manuals and Standard Plans in City of Los Angeles Right of Way (ROW).

B. The MRL North Hollywood Station West Entrance is needed due to the increase in ridership for both the MOL Bus Rapid Transit (BRT) and MRL subway systems. This underground passage connecting the MRL subway station to the MOL station will improve the existing crosswalk crossing Lankershim Boulevard/Chandler North and improve safety. In addition, this will considerably reduce the amount of pedestrian traffic at Lankershim Blvd, and provide a more efficient and safe passageway for the public using both transit systems.

C. The proposed underpass will tie into the existing subway station through the

KOP (knock-out-panel), located on the west side of the existing mezzanine level at the southwest corner of Lankershim Blvd and Chandler Blvd North.

D. Existing emergency exit stairs No.8 and hatch shall be demolished since it will

be in conflict with the proposed underpass construction. E. This is a Design/Build contract and the contractor is responsible to prepare the

temporary and final design plans, details, calculations, furnish to Metro, and install and construct the complete project. Drawings which indicate Work in public ROW shall be submitted to the City of Los Angeles (City) for review and approval. Cost of permit fees for the City and related governing agencies shall be a part of this contract.

1.2 SCOPE OF WORK

Contractor shall perform any additional existing site survey, if needed, including street profile of Lankershim Blvd and Chandler Blvd (North) within the project limits. In addition, the Contractor shall prepare construction documents, including final design and as-built drawings, design calculations, specifications, geotechnical and


site survey reports, and shall execute construction work per the following scope, including additional elements and activities, necessary to make the station’s west entrance a fully functional system. All final drawings and specifications within the City of Los Angeles ROW shall be reviewed and approved by the City, but shall not be submitted to the City prior to Metro reviewing plans first.

1. Projects Having Less Than One Acre of Disturbed Soil

Projects with construction activity that will result in less than one acre of disturbed soil, the Contractor shall comply with the following minimum water quality protection requirements:

a. Retain eroded sediments and other pollutants on-site and do not allow transportation from the site by sheet flow, swales, area drains, natural drainage, or wind. Control slope and channel erosion by implementing an effective combination of best management practices (BMPs). Such BMPs include scheduling grading during non-rainy seasons, installation of silt fences, sandbags and filler fabric, straw wattles, and planting and maintaining vegetation on slopes and covering erosion-susceptible slopes.

b. Protect stockpiles of earth and other construction-related materials from being transported from the site by wind or water.

c. Properly store and handle fuels, oils, solvents, and other toxic materials to not contaminate the soil or surface waters, enter the groundwater, or be placed where they may enter a live stream, channel, drain, or other water conveyance facility. Protect all approved toxic storage containers from weather, and provide berms around storage areas. Clean spills immediately and properly dispose of cleanup materials. Spills shall not be washed into live streams, channels, drains or other water conveyance facilities.

d. Do not wash excess or waste concrete into the public way or any drainage system. Retain concrete wastes on-site until they can be appropriately disposed of or recycled.

e. Deposit trash and construction-related solid wastes in covered receptacles to prevent contamination of rainwater and dispersal by wind.

f. Do not allow sediments and other materials to be tracked from the site by vehicle traffic. Provide approved BMP installations to stabilize construction entrance roadways to inhibit sediments from being deposited onto public ways. Accidental deposition must be swept up immediately and may not be washed down by rain or any other means. All loose soil and debris shall be removed from street areas upon starting operations and periodically thereafter as directed by the inspector.

g. Contain non-stormwater runoff from equipment or vehicle washing and any other activity at the work site.

h. The contractor shall protect all new and existing storm


drain system structures from sedimentation and concrete rinse, or other construction-related debris and discharges with gravel bags and filter fabric or by any other equal product approved by the engineer. Accumulated debris shall be cleaned up and properly disposed of by the contractor to prevent the materials from entering or being carried into stormwater conveyances.
