Lake and Reservoir Management | Year: 2010

As a water supply, Lake Waco, Texas, is subject to the provisions of the Safe Drinking Water Act and related regulations. Aside from concern over primary contaminants that affect human health, there have been taste and odor incidents of increasing frequency, duration and severity over the last decade; therefore, this comprehensive study was developed to define historical and existing water quality conditions and to project possible management scenarios. Practical management approaches to maintain or improve existing water quality conditions within the lake and immediate watershed were identified and evaluated for implementation. The declining water quality within the lake necessitated the construction of an additional treatment process at a cost of $40 million to facilitate compliance with newer drinking water regulations. The investigators sought to assess the magnitude and relative size of water and nutrient contributions to Lake Waco, allowing assessment of loading in relation to acceptable levels for maintaining desired conditions in the reservoir. Thirty-five specific tasks (studies) were conducted concurrently, investigating specific issues or mechanisms of interest in relation to the lake, its watershed and its users. The majority of the $2 million study cost was provided by the City of Waco, although the US Army Corps of Engineers, US Environmental Protection Agency, US Geological Survey, and Texas Parks and Wildlife Department made important contributions to the study. © 2010 Copyright by the North American Lake Management Society.

The challenging sustainability commitments of the London 2012 Olympic and Paralympic Games reflect a comprehensive approach to minimising the impact of the games on the environment while promoting social and economic improvement. The Olympic Delivery Authority's sustainable development strategy reflects industry best practice as well as national and regional policy. This paper considers the Olympic Delivery Authority's sustainability strategy, the challenges in developing and implementing it across the project, the resulting achievements - with particular focus on some of the projects - and the lessons which have been learned.

The fundamental aims of the Olympic Delivery Authority's procurement team were to deliver the required London 2012 contracts in time for construction to be completed by July 2011, and to implement policy objectives. This paper explains how venueclusters and pan-venue packages were used to centralise the supply of commodities and support policy objectives. It also reports how the NEC3 suite of contracts was selected and amended to reflect delivery obligations and brand restrictions, and how the contracts worked in practice. Source

The Olympic Park site in east London was fragmented, polluted and divided by pylons and railways. In preparation for the London 2012 Olympic and Paralympic Games, the UK's Olympic Delivery Authority has implemented environmental improvement on a huge scale - including remediating large swathes of the former industrial land, repairing and improving the waterways, removing invasive plants in river and rail corridors, and creating new habitats for native flora and fauna. This paper considers the London 2012 environmental strategy, the challenges in developing and implementing the strategy across the project, the achievements with regard to ecology, air quality, noise and waste, and the lessons which have been learned.

The UK Olympic Delivery Authority began to define the methodology for an ambitious construction programme on the 2.7 km2 Olympic Park site for the London 2012 Olympic and Paralympic Games, which came with significant constraints. The construction programme included 14 Games time venues and other buildings; the infrastructure and utilities sufficient to service a small town; 300 residential and commercial buildings to be demolished and 2.6 million m3 of soil to be remediated. This 6 billion construction programme was to be completed in 3.5 years. At its peak this resulted in 4500 vehicle movements each day, 81 tier 1 contractors, and 3000 tier 2 contractors together with their subcontractors and suppliers and up to 9000 people involved in construction.
