Some of the construction claims that Delve Underground works on involve evaluating a project’s problems and the resulting delays to the project’s schedule. We often rely on the contemporaneous monthly project schedule updates to evaluate the progress of work, critical path, and effects of delaying events on the work, but there’s another invaluable tool: a project timeline. A project timeline supplements the project schedule and can illuminate significant details about the job. All types of projects can benefit from having a timeline. Information used to create a timeline is best displayed in bar chart form. The project duration calendar becomes the basis for the horizontal timeline. The bars on the bar chart summarize relevant dates and milestones. The real benefit of a timeline is that it visually shows the events that occurred along the project’s duration.

At the Hartsfield-Jackson Atlanta International Airport, the automated people mover system was extended and the terminal was renovated at the baggage claim station as part of the Atlanta Plane Train Tunnel West Extension (PTTWE) progressive design-build project. The City of Atlanta is the project owner, and Delve Underground is the lead designer for the Clark/Atkinson/Technique design-build joint venture. The project added a switch and tail track west of the current western end of the Plane Train system to enable a reduced headway and to increase capacity for future ridership.

The current economy, characterized by high inflation and a degree of uncertainty, has brought on a reality for public agencies and other infrastructure owners that there is a need to do more with less. This extends to areas of maintaining, rehabilitating, replacing, or expanding their assets. Savvy infrastructure managers are always looking for ways to salvage existing facilities while making upgrades. This article examines how CSX Corporation (CSX) salvaged its existing bridge under circumstances that needed creative solutions. The bridge project had non-negotiables, including site access constraints and the inability to shut down rail service, except for one 24-hour period. CSX chose corrugated structural metal plate (CSMP) because of its adaptability to overcome these difficulties.

If you’re not familiar with fire design of concrete tunnel linings, you might assume that fire tests are conducted to validate that the lining has adequate strength capacity for a specified fire load (e.g., hydrocarbon or Rijkswaterstaat [RWS] curves). However, in most tests, this is not the case—at least not directly. Fire tests are performed for two main reasons.

About an hour northwest of Newark, #NewJersey, is the historic Roseville Tunnel, situated in Byram Township, Sussex County. The Roseville Tunnel Rehabilitation Project is a design-build project and is part of NJ TRANSIT’s (NJT) Lackawanna Cut-off Restoration. The Lackawanna Cut-off—a historic rail line in New Jersey and Pennsylvania—was originally built by the Delaware, Lackawanna & Western Railroad in the early 1900s. It runs from Port Morris Junction in New Jersey to Slateford, Pennsylvania. NJT’s restoration will extend passenger rail service from Port Morris, New Jersey, to a new rail station in Andover, New Jersey. The horseshoe-shaped Roseville Tunnel was completed in 1911. This rock tunnel was originally double-tracked and operated for freight and passenger transport from 1911 to 1979. It is mostly unlined, but has approximately 140 feet of concrete liner where a regional fault runs through the tunnel. The design-build team is led by Schiavone Construction Co. LLC, and Delve Underground is the lead designer. Eight specialized subconsultants are also on the design team.
