Responsiveness summary : United States Army Corps of Engineers : Waukegan Harbor, Lake County, Illinois : Section 401 water quality certification for dredging of the Waukegan Harbor approach channel and advanced maintenance area.

The approved project allows the Corps to dredge the Waukegan Harbor approach channel and advanced maintenance area. The area to be dredged lies immediately east of the north breakwater. It is approximately a rectangle 650 feet north and south and 1,400 feet east and west. The advanced maintenance area is a band along the north side of the channel. The approved project is for a 10-year certification, under which the Corps may remove 22,000 to 75,000 cubic yards of sediment per dredging event. The dredging depth is 22 feet and the amount to be dredged is about one foot of sediment. As a condition of the certification, disposal of the dredged sediment in Lake Michigan or the waters of the state cannot occur until the conditions of the certification are met. These conditions, which have been placed on the certification by Illinois EPA, ensure that the project meets state water quality standards and is consistent with the determinations of the Illinois Attorney General's Task Force on asbestos contamination at Illinois Beach State Park.

THE FEASIBILITY OF USING WEB-BASED TECHNOLOGY FOR THE MANAGEMENT OF DREDGING PROJECTS

The research investigates the feasibility of using web-based project management systems for dredging. To achieve this objective the research assessed both the positive and negative aspects of using web-based technology for the management of dredging projects. Information gained from literature review and prior investigations of dredging projects revealed that project performance, social, political, technical, and business aspects of the organization were important factors in deciding to use web-based systems for the management of dredging projects. These factors were used to develop the research assumptions. An exploratory case study methodology was used to gather the empirical evidence and perform the analysis. An operational prototype of the system was developed to help evaluate developmental and functional requirements, as well as the influence on performance, and on the organization. The evidence gathered from three case study projects, and from a survey of 31 experts, were used to validate the assumptions. Baselines, representing the assumptions, were created as a reference to assess the responses and qualitative measures. The deviation of the responses was used to evaluate for the analysis. Finally, the conclusions were assessed by validating the assumptions with the evidence, derived from the analysis. The research findings are as follows: 1. The system would help improve project performance. 2. Resistance to implementation may be experienced if the system is implemented. Therefore, resistance to implementation needs to be investigated further and more R&D work is needed in order to advance to the final design and implementation. 3. System may be divided into standalone modules in order to simplify the system and facilitate incremental changes. 4. The QA/QC conceptual approach used by this research needs to be redefined during future R&D to satisfy both owners and contractors. Yin (2009) Case Study Research Design and Methods was used to develop the research approach, design, data collection, and analysis. Markus (1983) Resistance Theory was used during the assumptions definition to predict potential problems to the implementation of web-based project management systems for the dredging industry. Keen (1981) incremental changes and facilitative approach tactics were used as basis to classify solutions, and how to overcome resistance to implementation of the web-based project management system. Davis (1989) Technology Acceptance Model (TAM) was used to assess the solutions needed to overcome the resistances to the implementation of web-base management systems for dredging projects.

Dredging the Cedar Point Lagoons

This picture shows the men of the Detroit Dredging Company hand digging lagoons for owner George A. Boeckling at Cedar Point. The lagoon network would be used for transportation so that visitors could reach the boat docks at the Hotel Breakers. They also made it possible to carry coal to the new electric power station. Visitors could also enjoy traveling the lagoons by themselves.
