Asset Management of Linear Civil Infrastructure – Through the Lens of a Changing Climate

Core linear civil infrastructure systems (e.g. roads, bridges, buried utilities and pipelines) are critical elements of society that meet our functional needs, sustain economic growth and development, and support our current standard of living through the transport of people, services, goods, water and energy. In Canada, approximately 60% of this core infrastructure is owned and maintained by local municipalities with a total asset value of $1.1 trillion [1]. Throughout much of North America, a significant proportion of this core infrastructure was built in the 1950’s and 1960’s. Although investments in public infrastructure have continued, these assets have experienced stress from deterioration due to ageing and weathering effects, deferred maintenance, and increased utilization. From the Canadian perspective, the variation in core infrastructure age over time, as a composite asset average, has fluctuated between 14 years and 18 years over the past 5 decades [2]. Approximately one-third of the existing Canadian infrastructure network ranks between “fair” and “very poor”, which is associated with limited funding, deferred maintenance and increased utilization [1]. This “investment gap” has pushed these assets toward 79% of used service life. The infrastructure gap has been estimated to be $60 billion (2012$) in Ontario, $145 billion (2013$) across Canada and exceeding $2 trillion (2016$) in the United States with a projected loss in gross domestic product of $3.9 trillion through to 2025 [1,3-5]. The annual deficit can be an order of magnitude greater than the annual budget where the reactive costs can be up to 10 times the preventative costs.

Iris Publishers- Open Access Journal of Civil Engineering

Iris Publishers - Open Access Journal of Civil Engineering Structure, Building Envelop and Form integration in Architecture Contemporary Architecture is witnessing a significant transformation, because of developments in technology that is releasing architects from the use of static forms and historical construction methods, to the use of more dynamic forms that integrate elements of structure, building envelop and form in designs. This paper briefly examines developments in architecture over time, in order to situate and discuss the current emerging trend of integration. The article starts from exploring the history of architecture and the form of buildings in the different eras. It then moves on to discuss the contemporary trend in building form, structure and envelope integration, exploring some of the factors that are drive the trend and discussion of implication for the form of future architecture.

Quality Control of Concrete in the Southern Region of Kingdom of Saudi Arabia Using Local Materials | Osama K Adwan

Osama K Adwan |  Quality Control of Concrete in the Southern Region of Kingdom of Saudi Arabia Using Local Materials Research Article A common concern amongst civil engineers is producing a good quality concrete on-site. This paper reports results of a study carried out to examine the quality of normal strength concrete production in the southern region of Kingdom of Saudi Arabia (KSA) made from local coarse aggregate namely Basalt. As all data were analyzed and examined statistically using Chebyshev’s theorem and the Statistical Empirical Rule (SER) method presented herein. It is concluded that, the normal distribution of all test results -in terms of the quality of concrete mix- was strongly agree with Chebyshev’s theorem and ACI 318-14 section 5.6.3. In addition, these results were considerably better than the Statistical Empirical Rule (SER) method. Overall, these concrete mixes, in this investigation, with 28 days compressive strength of 35 MPa can be used confidently in concr...
