Calatrava's Dallas: The Margaret Hunt Hill Bridge

Written by

Very much in keeping with Dallas' official “Live Large, Think Big” slogan comes a wonderful urban expression of the exuberance of this huge Texas city. The 400'-high Margaret Hunt Hill Bridge (MHH Bridge), designed by Santiago Calatrava, will span the Trinity River, connecting Dallas to West Dallas, and is expected to be complete in the spring of 2012, after 14 years of planning, design, budget cuts, redesign, and construction. The Trinity River Corridor Project, backed by a $245 million bond passed by Dallas voters in 2005, brought Calatrava to town to design three bridges over the Trinity River. Calatrava's bridges will provide an architectural signature for the Trinity River Corridor Project and hopefully will become a symbol of Dallas, nationally and internationally.

I was definitely NOT shopping.

Written by

Tell someone that you work in construction -- heavy construction, that is -- and they most likely will have a mental image of earth-moving equipment, trenches, concrete, and asphalt. Paperwork may not come to mind, nor contracts or documents. Yet the success of a construction project depends not only on the work at the site but also on the paper documentation that defines what must be done.

Maintenance Tips: Washing Machines

Written by

According to the Study of Life Expectancy of Home Components, which was prepared in 2007 by the National Association of Home Builders (NAHB), the average life expectancy of a washing machine is 10 years. While washing machines are not made to last forever, performing simple maintenance will help to ensure they last as long or longer than expected, and will actually reduce the likelihood that your washing machine will be the cause of significant water damage to your home.
