Salt-induced reinforcing steel corrosion in concrete bridges has undoubtedly be come a considerable economic burden to many State and local transportation agencies. Since the iron in the steel has a nat ural tendency to revert eventually to its most stable oxide state, this problem will, unfortunately, still be with us, but to a much lesser degree due to the use of various corrosion protection strategies currently used in new construction. The adoption of corr osion protection measures in new construction, such as the use of good design and construction practices, adequate concrete co ver depth, low-permeability concrete, corrosion inhibitors, and coated reinforcing steel is significantly reducing the occurren ce of reinforcing steel corrosion in new bridges. Because concrete has a tendency to crack, the use of good design and constructi on practices, adequate concrete cover depth, corrosion-inhibiting admixtures, and low- permeability concrete alone will not a bate the problem. Even corrosion-inhibiting admixtures for concrete would probably not be of use when the concrete is crack ed. This situation essentially leaves the reinforcing steel itself as the last line of defense against corrosion, and the use of a barrier system on the reinforcing steel, such as epoxy coating, another organic coating, or metallic coatings, is even more c ritical. It is likely that there may never be any organic coating that can withstand the extreme combination of constant wetting and high temperature and high humidity that reinforcing steel is exposed to in some mari ne environments. Either steel bars coated with a sufficiently stable metallic coating or some type of corrosion-resistant solid metal bars would have to be used. There are some very convincing reports of good corrosion-resistance performance shown by epoxy -coated steel bars in concrete bridge decks where the concrete does not remain constantly wet and other exposure conditions are not as severe. Recent improvements to the epoxy coating specifications and the tightening of requirements on the prop er storage and handling of epoxy-coated reinforcing steel at construction sites will ensure good corrosion protection. For construction of new prestressed concrete bridge members (where for structur al or other considerations epoxy-coated strands cannot be used), the use of a corrosion-inhibitor admixture in the conc rete or in the grout, in conjunction with good construction designs and practices, would provide adequate corrosion protection . However, the long-term effectiveness of all commercial inhibitor admixtures has not been fully verified

The topics of budgeting, costing and estimating for injection moulding are the source of much confusion in the plastics industry and from the research carried out by the author, there does not appear to be any kind of authoritative published work that addresses these topics. This book addresses them head-on to explain in detail all the stages involved from budgeting to the final estimate. This book discusses and defines the different methods of budgeting, costing and estimating that are normally used within the injection moulding industry. In order to establish the costing system, the operating costs first have to be identified and quantified by means of a budget. Based on the budget, a costing system can then be developed that can be applied to determine the manufacturing cost of each product a company manufactures. The underlying theme of this book is the maximisation of profits through the control of costs. Hence, emphasis is placed on ensuring the understanding of costing and estimating models through discussion and examples. This book will be of considerable value to managers of injection moulding companies, to accountants who work in these companies and users of the equipment who may have involvement in the costing and budgeting of new projects.

Installed in Windows 7 32 bit and 64 bit.
Remember to use a 32 bit Excell (see my first post of RSA 2012).
When installed in 64bit with Office 2010 - Esop macro error.
Installed 32 bit Excell 2003 (for Wood need a update (office2003-KB907417-FullFile-ENU.exe) free from Microsoft.)
Now the excell works but something goes wrong with the licensing (adlm error 20) and the spreadsheet works only on demo mode.
In the 32 Windows 7 with RSA Pro 32 bit works without problems.
I installed in a fresh (from image) Windows 7 64 bit SP1 but maybe the licensing error reason is only in my system so please check.

One of the major difficulties in predicting the capacity of pipe piles in sand has resulted from a lack of understanding of the physical processes that control the behavior of piles during installation and loading.
This monograph presents a detailed blue print for developing experimental facilities necessary to identify these processes. These facilities include a unique instrumented double-walled pipe-pile that is used to delineate the frictional stresses acting against the external and internal surfaces of the pile. The pile is fitted with miniature pore-pressure transducers to monitor the generation of pore water pressure during installation and loading. A fast automatic laboratory pile hammer capable of representing the phenomena that occur during pile driving was also developed and used. Finally, a pressure chamber; feedback control system; data acquisition system; loading frame; sand handling, pluviating, saturating, and drying apparatus have been integrated to allow convenient load testing of piles under simulated field conditions. The experimental apparatus is presented with sufficient details to allow readers to duplicate or modify the design to suit their own needs.
A number of load tests were carried out to identify the effects of inertia and build-up of pore water pressure on pile plugging. Continuous measurement of dynamic and static excess pore pressures, frictional and end bearing stresses, and the elevation of the soil inside the pile during installation and loading are presented. The results of the testing program validates the performance of the developed apparatus, and provide unique insights into soil-structure interaction during pile driving and subsequent loading. The work contributes to a better understanding of pile behavior.
