Stringless Portland Cement Concrete Paving, February 2004

This report describes results from a study evaluating the use of stringless paving using a combination of global positioning and laser technologies. CMI and Geologic Computer Systems developed this technology and successfully implemented it on construction earthmoving and grading projects. Concrete paving is a new area for considering this technology. Fred Carlson Co. agreed to test the stringless paving technology on two challenging concrete paving projects located in Washington County, Iowa. The evaluation was conducted on two paving projects in Washington County, Iowa, during the summer of 2003. The research team from Iowa State University monitored the guidance and elevation conformance to the original design. They employed a combination of physical depth checks, surface location and elevation surveys, concrete yield checks, and physical survey of the control stakes and string line elevations. A final check on profile of the pavement surface was accomplished by the use of the Iowa Department of Transportation Light Weight Surface Analyzer (LISA). Due to the speed of paving and the rapid changes in terrain, the laser technology was abandoned for this project. Total control of the guidance and elevation controls on the slip-form paver were moved from string line to global positioning systems (GPS). The evaluation was a success, and the results indicate that GPS control is feasible and approaching the desired goals of guidance and profile control with the use of three dimensional design models. Further enhancements are needed in the physical features of the slipform paver oil system controls and in the computer program for controlling elevation.

Plant Size and Frequency of Strike, December 1970

In Illinois and Iowa, the author finds that plants with approximately 750 employees have suffered the highest strike-frequency rate. Why at this size? Among other explanations, it is posited that in significantly smaller plants labor-management relations can be personalized-and tensions reduced-while in appreciably larger plants sophistication in dealing with disputes may, of necessity, have been developed.

06033-015 Fox River Watershed Final Report

With WIRB funding the Fox River Ecosystem Development board will install prioritized practices identified by assessments within the impaired segment of Fox River that currently will not be funded by Iowa Section 319 or Watershed Protection Funds. The FRED board is also asking for funding for a three year position for continuing assessment, planning, and technical assistance. Through various funding sources local work groups have been able to address some of the critical and high priority areas. But, as further assessments are made, commitment, and need expressed from landowners grow, the FRED board and SWCD districts in both Iowa and Missouri are committed not only to seek funding to continue water quality efforts for more practices but also enhance and protect existing practices and investments that protect our water quality and economic viability in both states.

09020-012 Fox River Watershed Final Report

With WIRB funding the Fox River Ecosystem Development board will continue to install prioritized practices identified by assessments within the impaired segment of Fox River. The FRED board is also asking to continue funding for a new 5 year position for assessment, planning and technical assistance. With new assessments and water quality monitoring already being done on the impaired segment of the Fox River a lot of valuable information is at hand. Ecosystem Development board is requesting funding from WIRB to install grade stabilization structures, water sediment basins, and terraces to reduce sediment delivery to Fox River. The FRED board in both Iowa and Missouri are committed not only to seek funding to continue water quality efforts for more practices but also to enhance and protect existing practices and investments that protect our water quality and economic viability in both states. We are off to a good start and want to continue our progress on the Fox River.
