This manual provides guidance on evaluating the condition of the concrete in a structure, relating the condition of the concrete to the underlying cause or causes of that condition, selecting an appropriate repair material and method for any deficiency found, and using the selected materials and methods to repair or rehabilitate the structure. Guidance is also included on maintenance of concrete and on preparation of concrete investigation reports for repair and rehabilitation projects. Considerations for certain specialized types of rehabilitation projects are also given.

This working manual covers everything from theory, practical design, templates, installation, filling, equipment, maintenance to removal. With the combination of the TVA Technical Monograph 75-Steel Sheet Pile Cofferdams on the Rock manual and the US Corps of Engineers manual - Theoretical Manual for Design of Cellular Sheet Pile Structures our Cellular Cofferdams handbook make for an excellent reference book. Cellular Cofferdams, the large, barrel-like, interconnected structures formed of steel sheet piling and filled with coarse soil. Generally utilized for dewatering large construction sites as well as building piers, quaywalls, bulkheads, breakwaters and artificial islands. Over the years, a few papers on design theory have come forth, but only one complete publication devoted to the entire subject.

This first report deals with some of the major development issues confronting the developing countries and explores the relationship of the major trends in the international economy to them. It is designed to help clarify some of the linkages between the international economy and domestic strategies in the developing countries against the background of growing interdependence and increasing complexity in the world economy. It assesses the prospects for progress in accelerating growth and alleviating poverty, and identifies some of the major policy issues which will affect these prospects.
