Global Challenges,Local Solutions: The City as an Ecosystem of Events

In a time of global challenges, cities are critical not only as vehicles for progress, but also as centers of diversity and resilience. Confronted with intensifying climates, and social, ecological, and economic issues, McGregor Coxall focuses on the stories people tell in making their cities. Our projects accept and challenge these stories which underpin city-making: the engine of economic progress, the marketplace of cultural production, and the myth of our separation from “nature.” The success of contemporary city is built on a paradoxical relationship with two pressures: global development and environmental impacts. To address these crises, McGregor Coxall works at two scales, simultaneously, on all of our projects: in the large-scale realm of regional economic development and ecosystemic operations, and at the scale of the person, the street, and the neighbourhood. The systemic understanding provides the contextual basis by which projects perform, economically and environmentally, while our understanding of communities makes each project a genuine product of its time, place, and culture.

City in transition: Podgorica,Europe's youngest capital city

Podgorica, known as the “city under the mountain,” rests at the intersection of five riversand is Europe's youngest capital. Over a 2000-year-long history, Podgorica has experienced turbu-lence. The city has suffered conquests, wars, nearly complete destruction in WWII, associated with war-related conflicts in the 1990s, and gained its independence at the beginning of the 21st century. Today, Podgorica is a vibrant, dynamic, and rapidly growing city, with current developments that reflect the consequences of post-socialist economic, institutional, social, and cultural transition. In this case study, the development of the built environment of Podgorica is presented in six stages: Roman, Ottoman, Principality of Montenegro and Kingdom of Yugoslavia, socialist, transitional, and contemporary. The study shows the influence of each period in the development of the city and highlights two major challenges of present-day architecture, that is, growing into a modern-day metropolis and the challenge of juxtaposing contemporary Podgorica with Titograd and old Podgorica.     

Effects of chloride,sulfate and natural organic matter (NOM) on the accumulation and release of trace-level inorganic contaminants from corroding iron

This study examined effects of varying levels of anions (chloride and sulfate) and natural organic matter (NOM) on iron release from and accumulation of inorganic contaminants in corrosion scales formed on iron coupons exposed to drinking water. Changes of concentrations of sulfate and chloride were observed to affect iron release and, in lesser extent, the retention of representative inorganic contaminants (vanadium, chromium, nickel, copper, zinc, arsenic, cadmium, lead and uranium); but, effects of NOM were more pronounced. DOC concentration of 1 mg/L caused iron release to increase, with average soluble and total iron concentrations being four and two times, respectively, higher than those in the absence of NOM. In the presence of NOM, the retention of inorganic contaminants by corrosion scales was reduced. This was especially prominent for lead, vanadium, chromium and copper whose retention by the scales decreased from >80% in the absence of NOM to <30% in its presence. Some of the contaminants, notably copper, chromium, zinc and nickel retained on the surface of iron coupons in the presence of DOC largely retained their mobility and were released readily when ambient water chemistry changed. Vanadium, arsenic, cadmium, lead and uranium retained by the scales were largely unsusceptible to changes of NOM and chloride levels. Modeling indicated that the observed effects were associated with the formation of metal–NOM complexes and effects of NOM on the sorption of the inorganic contaminants on solid phases that are typical for iron corrosion in drinking water.

Stormwater control measure (SCM) maintenance considerations to ensure designed functionality

Great investment is made in the design and installation of stormwater control measures (SCMs). Substantial research investment, too, is made to optimise the performance of SCMs. However, once installed, SCMs often suffer from lack of maintenance or even outright neglect. Key maintenance needs for wet ponds, constructed stormwater wetlands, bioretention, infiltration practices, permeable pavement, swales, and rainwater harvesting systems are reviewed with many tasks, such as the cleaning of pre-treatment areas and the preservation of infiltration surfaces, being common maintenance themes among SCMs. Consequences of lacking maintenance are illustrated (mainly insufficient function or failure). Probable reasons for neglect include insufficient communication, unclear responsibilities, lack of knowledge, financial barriers, and decentralised measures. In future designs and research, maintenance (and lack thereof) should be considered. Assessing the performance of SCMs conservatively and including safety factors may prevent consequences of under-maintenance; and requiring regular inspection may help to enforce sufficient maintenance.     

预应力锚索应力测量误差的试验研究与对策

了解锚索应力状态时,锚力计示值与千斤顶示值之间普遍存在着较严重的不匹配现象,通过室内外试验和工程数据分析的汇总分析,得到这种不匹配现象主要由仪器设备使用错误及数据错误、测量仪器误差、构件误差及安装误差等施工误差、锚索张拉及锁定时应力损失等原因造成。把千斤顶示值和锚力计示值有机结合,通过现场试验建立两者示值之间的对应关系,能够对锚索的真实应力状况有个较为全面的、准确的了解。     

A sustainability assessment framework for bridges – a case study: Victoria and Champlain Bridges,Montreal

This paper deals with the development of a framework for assessment of sustainability of bridges, including related technical, economic, environmental and social issues. Sustainable infrastructure assets require diligent conception and design of facilities (with diligent choice of materials and construction techniques), high quality construction, and operations, involving routine maintenance, with optimised life-cycle performance and costs, and minimum impact on the environment over a stipulated long service life and beyond. Partial details of design, construction, maintenance and rehabilitation/renovation of the four versions of the 3-km long Victoria Bridge (1859, 1898, 1958 and 1988) are summarised, along with the partial details of design, construction, severe deterioration and subsequent rehabilitation of the nearly 6-km long, 6-lane Champlain Bridge. Sustainability of both bridges was assessed by implementing the proposed sustainability framework developed in this research programme, along with the use of the analytical hierarchy process which involved evaluation of pairwise comparison of the various categories to assist with evaluation of the sustainability scores. These scores indicate that all four forms of Victoria Bridge (1859, 1898, 1958 and 1988) are partially sustainable, or sustainable, while the Champlain Bridge is unsustainable. This framework can be appropriately adapted for assessing the sustainability of other infrastructure assets.
