The General Health Questionnair(GHQ) is frequently used as a measure of mental well-being with those people with values below a certain threshold regarded as suffering from mental stress. Comparison of mental stress levels ...
In many tunneling and excavation projects, free-field vertical ground movements have been used to predict subsidence and empirical limits have been employed to evaluate risk. Validity of such approaches given the reality ...

Foundation reuse is a tricky business at the best of times. For structures predating the mid-20th century, the challenge is exacerbated by the presence of a variety of foundation types, techniques, and materials no longer ...
Sustainability in the construction industry can only be achieved through a radical rethinking of building construction and reuse. This paper outlines the problems and offers innovative solutions that embrace technological ...
There is a large empirical literature on policy measures targeted at children
but surprisingly very little theoretical foundation to ground the debate
on the optimality of the different instruments. In the present paper, ...
The experimental procedures and results are presented for a one-tenth scale laboratory investigation of changes in achievable grouted zones through alterations in helical pier parameters. The parameters investigated were ...
Building reuse is a linchpin to managing solid waste. Despite the various benefits beyond contributing to sustainability that can be realized through building reuse, including direct and indirect cost savings, truncated ...
The decreased cost and increased processing speed for terrestrial laser scanners have made this remote sensing procedure much more attractive. The approach has two major advantages over traditional surveying: (1) a ...
Rehabilitation of building structures is a critical need facing numerous older urban areas. Many of these structures are supported on pile groups, which do not have adequate load capacity to support the demands expected ...
The grouted, helical pier system (GHPS) is proposed as an example of a capacity improvement option for existing pile foundation groups. This paper explores the relative relationships between these geotechnical elements ...
