AGENDA

  • Project Process - Phase I, II, & III
  • Overall guiding principles
  • I-290 construction approach
  • I-290 construction schedule
  • Construction mitigation
  • Best Practices

CONSTRUCTION CONSIDERATIONS BY PHASE

  • Phase I – Planning

– Basic constructability and construction sequence – Right of way and traffic management – Letter of Intent

  • Conceptual outline of commitments & costs
slide-4
SLIDE 4

CONSTRUCTION CONSIDERATIONS BY PHASE

  • Phase II – Design

– Geotechnical/soils surveys (used to refine structural design and identify any special circumstances) – Detailed engineering plans

  • Detailed construction staging plan
  • Specifications – project community context
  • Refine cost estimates

– Intergovernmental agreements

  • Details and refined costs

CONSTRUCTION CONSIDERATIONS BY PHASE (CON’T)

  • Phase III - Construction

– Implement project plans and specifications – Adjust to field conditions as appropriate – Communicate status and coordinate construction activities with communities

OVERALL CONSTRUCTION GUIDING PRINCIPLES

  • Provide safe & efficient work zones during construction
  • Minimize adverse effects to the traveling public:

– Pedestrian, transit, bicycle, and auto

  • Implement strategies to minimize community

disruptions

  • Inform surrounding communities and affected users of

impacts & available travel options

slide-7

I-290 CONSTRUCTION APPROACH

  • Early improvements prior to mainline construction

– Off system roadway improvements:

  • Offers additional travel options
  • Local community benefits

ADVANCE WORK/IMPROVEMENTS

  • Advanced work

– I-55 Express Toll Lane (I-355

to I-90/94)

– Off-System Arterial Improvements

CONCEPTUAL CONSTRUCTION SCHEDULE

  • 8 year construction schedule estimate (Phase III)

– 4 years mainline construction

  • Expressway (some periods of 4 lane
  • peration)
  • Major interchanges
  • Mainline drainage
  • Retaining walls & noise walls

– 4 years advance work

  • Local cross-road & pedestrian bridges

(as practical)

  • CTA, CSX, IHB railroad bridges
  • Utilities & retaining walls (as practical)

I-290 CONSTRUCTION STAGING

  • Implement construction staging to minimize disruptions

– Advance local improvement projects prior to mainline – Minimize duration of mainline construction (4 years) – Minimize duration & extent of mainline lane closures – Avoid closing two consecutive interchange/access points

  • 25th Avenue & 1st Avenue
  • Harlem Avenue and Austin Boulevard
  • Central Avenue and Lamarie/Cicero Avenue

– Avoid full closure of two consecutive cross roads – Maintain one entrance to each Blue Line platform

CONSTRUCTION SCHEDULE SUMMARY

  • 8 Year Construction Schedule

– 4 years for advance work/improvements – 4 years for mainline construction

  • Key Schedule Drivers

– IHB Railroad, CTA, and CSX Railroad bridges – Utility relocations

CONSTRUCTION EFFECTS / MITIGATION CONCEPTS

  • Overall project balance
  • Community, safety, cost, schedule

Effect General mitigation strategy

Vibration/settlement Specifications – construction methods – monitoring Noise Specifications – restrictions as appropriate Dust Specifications – water trucks – demolition methods Traffic patterns Specifications – restrictions as appropriate – hotline Time of day Nighttime mainline work Specifications – restrictions as appropriate Materials storage Specifications – restrictions as appropriate

slide-19
SLIDE 19

VIBRATION / SETTLEMENT

  • Vibration/settlement specifications

– No driven shafts allowed

  • Monitoring

– Identified locations and predefined threshold values – Monitoring of locations during construction – Corrective action and equipment shutdowns in areas if thresholds are exceeded

slide-20
SLIDE 20

NOISE

  • Construction noise

– Type of work – Day or night – Contractor means and methods – Balance

slide-21
SLIDE 21

DUST

  • Contracts include pay item for dust control
  • Reduced vehicle speed on unpaved surfaces
  • Cover haul vehicles
  • Erosion control measures

BEST PRACTICES

  • Detailed analysis & Coordination (design – phase II)

– Sequence of work in each community – Likely construction effects and mitigation strategies – Local traffic patterns – Construction phase coordination/communication plan

slide-23
SLIDE 23

23 23

BEST PRACTICES

  • Communication (construction – phase III)

– Local point of contact – Full time IDOT contact – Weekly contractor meetings (work to date, upcoming work) – Project hotline – Website – Flyers and signage
