554 Transportation Research Circular E-C058: 9th National Light Rail Transit Conference
• Street alignment shown in the gray shading with street names and major structure
crossings.
• Major civil contract segments, reaches, and areas defined by contractors.
• Light rail structure construction in the green-shaded area.
• Major work scope components:
– Storm/sewer construction in aqua blue;
– Street and sidewalk work in light orange (also depicted traffic on inside lanes);
– Track construction (traffic in outside lanes) in dark orange;
– Overhead catenary and traction electrification (TES) construction in light green;
– Signals/communications installation in magenta checkerboard;
– Integrated testing in transparent navy blue;
– Simulated revenue in maroon;
– Station and artwork in lavender
– Bridge substructure in gray and white diagonal stripes;
– Superstructure in gray shading;
– Pile driving with directional arrows with rounded ends;
– Girder setting with directional arrows with diamond-shaped ends;
– Deck forming in light orange with dark orange dotted borders by units (units
defined by contractor);
– Dark orange lines depict plinth construction;
– Blocks with brick-like pattern depicting systems building construction;
– Green-shaped building with black outline, monopoly house-like, depicts
substation equipment installed and energized;
– Sharks with gray blocks depicting in-stream work window period; and
– Green block with blue dots depicting wetland construction.
• Major civil to systems milestone turnovers depicted with blue-dotted line.
A legend is provided on the bottom of the geographic schedule, as well as a revision date.
This schedule is updated at least quarterly, and has served as an excellent tool to use as we
review contractor’s updated schedules and while we update our own master schedule. It also
serves as an excellent tool to evaluate civil to systems turnover milestones and see float, if any,
between the various contract segment completions. For instance, it became apparent early on in
the project that if civil contractors continued their ahead of schedule progress, and if systems
crews could take advantage of earlier access dates, that we could potentially open up our system
4 months early.
Interstate MAX light rail project staff have became aware of the many details that are
offered in this pictorial and have come to use this schedule as a tool to support some of their
work. Staff have used this as an alignment map when giving tours, review street crossings, and
get stationing orientation, etc. This schedule also became favored by our customer relations staff
as they struggled with how to communicate our overall schedule timeline to the public. A bar
chart summary schedule was available. (FIGURE 3 The CPM summary schedule.) This schedule
was prepared early on in the project and used as a summary schedule for FTA presentations. This
is a simple timeline showing the major components of work and the milestones met along the
way, including such things as the 60-90-100% design phases. However, customer relations liked
the detailed geographic schedule and they worked at putting together a simpler version that
showed the timeline in quarters and simplified the shading to just reflect the major scope of work
