Analysing scenarios of transport infrastructure funding and financing
Published in Athena Roumboutsos, Hans Voordijk, Aristeidis Pantelias, Funding and Financing Transport Infrastructure, 2017
The Combiplan project, financed through public sources, included the construction of a new rail and motorway across the centre of the Nijverdal city over a distance of 6 kilometres, as part of a transportation link connecting the cities of Zwolle, Nijverdal and Almelo in the Netherlands. The infrastructure built is connected to the central train station. A 500 metres length tunnel that accommodates two train tracks and 2 by 2 lanes is part of the project. The tunnel alignment goes along the old railway path. The width of the tunnel structure ranges from approximately 26 to 36 metres. The tunnel depth varies along the route between 6 and 10 metres. Local infrastructure was relocated for the new project. Two slow traffic depressed crossings, two road bridges, two railway bridges, a railway viaduct and the necessary noise barriers were also built.
Problems in carrying out construction projects in large urban agglomerations on the example of the construction of the Varso building complex in Warsaw

A section of site of the Varso Tower building was built-up. It contained the technical facilities serving the Central Train Station and their pile foundation, the air intake ventilation, pump station tanks, retaining walls and ventilation ducts. Accordingly, the construction of the diaphragm wall of the building had to be adjusted after the surveying of the existing structures that would have otherwise caused a collision.

The platforms, escalator declines and ventilation shafts of Parliament Station were excavated in the Melbourne Formation. Within the area of the Station, only the top 1 to 2m from natural surface was composed of Quaternary colluvium and fill.

The reservoir was first impounded in the year 1959, having a storage capacity of 349.96 × 106. Gates were installed on the dam in 1972, which increased the capacity of the reservoir to 415.41 × 106 (increment of 65.45 × 106). Bathymetry survey was executed in this reservoir, in the year 1988, 1996 and 2000. These surveys were conducted in the post-monsoon period (November–February) of each survey year. Uniformity in benchmarking was considered during the conduct of these surveys. Survey of India Authority had established the great trigonometrical survey benchmark near the dam site. The benchmark has been permanently fixed, reference survey station, having known elevation with respect to a standard datum, i.e. mean sea level. Using this permanent benchmark, a permanent chart datum has been established by the reservoir authorities, to measure the reservoir water surface elevation. Chart datum had been selected as the benchmark at the start of the hydrography survey. Generally, the surveys were carried when the water was still, i.e. there was no inflow or outflow from the reservoir (post-monsoon time), the water surface elevation would not vary and therefore the datum was considered to be the same for the entire survey period. In the event of variation in water surface elevation, the variation in elevation during the survey period was compensated in the preparation of the reservoir bathymetry. The RCL observed between 1988–1996 and 1996–2000 surveys were 63.85 × 106 and 17.2 × 106, respectively (Figure 5). The model parameters were calibrated for the period 1988–1996 (8 years). Using these calibrated parameters the RCL for the period 1996–2000 (4 years) was computed. This computed reservoir capacity was compared with the observed capacity loss of Shetrunji reservoir.
