Raina's Bridge.... BRIDGE WORKMAN Series # 10 of 23 This booklet covers - in a workman-like manner - FIVE important Bridge-Design issues, viz: Can Design be taught The basic principles of practical structural Analysis and Design of a Bridge A Practitioner’s Guide to Estimating Safe Bearing Capacity of Substrata for Footings, Wells and Piles. Some details about PRESTRESSED CONCRETE and PRESTRESSING. Estimating the “Nett Dependable Passive – Less – Active Earth-Pressure relief from the undisturbed soil-mass gripping the Well-foundation between MAXIMUM-SCOUR-LEVEL to FOUNDING-LEVEL”

About this Training Series # 9 This little book is probably the smallest sized explanatory on the subject, explaining the issues in a real “compendium style” – comprehensively, yet concisely!! While the “Construction & Design of Cable-Stayed Bridges” by Walter Podolny and John Scalzi gives extensive details about construction and Design of Cable-Stayed Bridges, the second chapter of the present little book describes extensively the “ Systems & Strategies” for their Workman-like “ Rehabilitation & Maintenance”. All in all, this little book makes a delightful reading, one which is extremely informative and highly useful…… and BREVITY IS ITS SOUL in a field that is too full of dogged details !!.

About this Training Series # 8 After tracing the development of the Bridge-FORM and how the superstructure section improved from a SOLID SLAB to Arch, to VOIDED SLAB, to CONTINUOUS BEAM, to BOX-FORM, in REINFORCED and PRESTRESSED CONCRETE in COMPOSITE SECTION and STRUCTURAL STEEL, and further, after studying the nuances of Contractors’ tricks-of-the-trade, very detailed quantity-figures of various types of super and substructures as well as of various specific structural elements, have been given. Various types of RIVERINE BRIDGES and VARIOUS STRUCTURAL FORMS OF FLYOVERS have been considered. A brief explanatory of the “GLOBAL RESILIENT TRANSPORT PROGRAM”, the “CLIMATE CHANGE EFFECTS ON BRIDGES, and the MEANS OF MITIGATING THEIR ADVERSE EFFECTS” have been presented in a compendium (concise but comprehensive) manner.

About this Training Series #7 This mini treatise describes lucidly and, in a practice-oriented workman-like manner the following three important issues:#1 ‘Construction Quality – Assurance and Procedures’#2 ‘Construction Contract “Price Escalation” and how to pay for it’ and #3 ‘Initial Site-actions needed prior to commencing work at site’

About this Training Series #4 This concise but comprehensive mini treatise on the subject of structural concrete briefly covers the all-important disciplines of:  • design of High Strength concrete mix. • Its statistical control for quality • Concrete in Hot-weather and aggressive environment and in sea-water surroundings • Durability and deterioration of structural concrete • High Performance Structural Concrete • Strength and Properties of Structural concrete

About this Training Series #3 This short volume briefly enumerates and pin-pointedly draws the engineer’s attention to the otherwise ever divergent subject matter of the specifications for some important repair-materials, and repair methods, procedure and techniques concerned with structures in general and Bridges in Particular.

About this Training Series #2 This compendium style – Comprehensive yet Concise – Book, lucidly explains the intrinsic details regarding Load capacity evaluation, Load-Testing performance monitoring of bridges and Non-Destructive Testing of concrete, steel and some other structural elements.The workman-like explanation is neither exacting nor loaded with exotica. It explains the subject in a simplified manner, which the qualified engineer will willingly comprehend.

About this Training Series #1 It addresses the all-important issues of “Inspection, Rehabilitation, Repair & Strengthening” of Bridges. In today’s context, Bridges are the most important links in a Highway Systems which form the backbone of the Infrastructural development.

A bout this Training Series #6 This little book alerts the engineer about some of the highly important ‘Construction issues’ which can plague a construction contract both during its currency and even after the main work might have been completed. All this may delay the settlement of the contractor’s ‘Final Bill’ always a red herring, which can lead to further claims, counter claims, court cases and litigation.

About this Training Series #5 This little book lucidly answers the most disturbing questions of:#1 “Why do bridges in our part of the world distress and demise much earlier than in many of the first-world countries” and#2 “Monitoring the effects of ‘Plant Production rates’ and ‘Job efficiency factors’ on the progress of a construction contract”The first topic is an eye opener regarding the havoc that is caused by the laxity in understanding ‘the nuances’ and ‘the subtleties’ and even some ‘ordinary precautions’ in the construction procedures in the field.
