Charles suggests that a bridge be included in the design as an alternative to the architect’s previous idea to include stepping-stones. Although the architect acknowledges that a bridge could be included, Anna registers Charles’ suggestion as an action that: “compromising your design all the time” (A1, 1152). The architect response: “it’s not necessarily a compromise but if there’s a good reason for changing it let’s change it” acknowledges Charles’ idea without committing to adopting this. I infer that the architect is making it known that modifications to the design are acceptable actions for the client representatives in this situation, however the architect has local agency (at that moment in time) to decide which design ideas will be taken forward within the scheme.
Managing Existing Bridges – On the Brink of an Exciting Future

The presented methods are only stepping stones toward a new generation of BMS that will integrate BIM and allow more accurate and prompt information on bridge behavior. Current databases need to be enhanced with BIM. The data generated during the design and construction process must be handed to the owner or operator that act henceforth as their trustees. It is essential that this data can be transparently and intuitively used in the exploitation phase. To this end, the owners need to set requirements that are independent of software packages used in design and construction phase.
Influences of urban stormwater management ponds on wetlandscape connectivity

This study has filled a research gap on the landscape connectivity of natural wetlands and a novel ecosystem (i.e. human-created stormwater management ponds) in urbanizing areas. We found that landscape connectivity was impacted by wetland loss and creation of SWM ponds, and that these features contribute to connectivity in different ways. First, connectivity decreased with wetland loss, as shown by a decrease in the number of links between wetlands (NL) over the study period. Second, SWM ponds were less connected than wetlands, shown by lower dPC and dPCflux values. Lastly, SWM pond creation increased connectivity for the combined network of wetlands and SWM ponds. This contribution is shown by higher NL for the combined system of wetlands and SWM ponds than for wetlands alone. Additionally, higher dPCconnector values for SWM ponds indicate that SWM ponds might act as stepping-stones in the combined wetland-SWM pond system. Following Taylor, Fahrig, and With’s (2010) description of landscape connectivity, our discussion in Sections 4.1 and 4.2 describes the physical structure of the landscape, with links to the implications of this structure for species moving through the landscape. We further describe the potential implications of connectivity in the context of species within our study area in Section 4.3.
