Many major construction projects have incurred cost overruns; cost estimates used to decide whether important transportation infrastructure should be built can mislead grossly and systematically. [2] Cost overrun is distinguished from cost escalation, which is an anticipated growth in a budgeted cost due to factors such as inflation.
A portion of the runway behind a displaced threshold has three markings: [1] White arrows along the center line of the runway; White arrow heads across the width of the runway just prior to the displaced threshold bar; A 10 feet (3.0 m) wide white threshold bar across the width of the runway at the displaced threshold
Buildability assessment is employed to identify obstacles before a project is actually built to reduce or prevent errors, delays, and cost overruns. [1] CII defines constructability as “the optimal use of construction knowledge and experience in planning, design, procurement, and field operations to achieve overall project objectives”. [2]
A displaced threshold often exists because of obstacles just before the runway, runway strength, or noise restrictions making the beginning section of runway unsuitable for landings. [25] It is marked with white paint arrows that lead up to the beginning of the landing portion of the runway.
The US Army's Future Combat Systems [4] was cancelled in 2009 due to cost overruns. Marine Corps' Expeditionary Fighting Vehicle [ 5 ] vehicle programs was cancelled in 2011 due to cost overruns. The US Navy's Zumwalt -class destroyer 's production cost increased from a projected $3.15 billion to $5.82 billion per ship, triggering a Nunn ...

Under the 2007 Regulations appointments for similar roles were required for notifiable projects. The duty to notify now lies with a client and the threshold for notification is raised. The scope of what constitutes ‘construction work’ has been increased.
Proposed after German Reunification, this is a set of major construction projects meant to increase and improve transport links between East and West Germany.
