Without proper hydraulic fill and suitable specialised equipment, many major infrastructure projects such as ports, airports, roads, industrial or housing projects could not be realised. Yet comprehensive information about hydraulic fill is difficult to find. This thoroughly researched book, written by noted experts, takes the reader step-by-step through the complex development of a hydraulic fill project. Up-to-date and in-depth, this manual will enable the client and his consultant to understand and properly plan a reclamation project. It provides adequate guidelines for design and quality control and allows the contractor to work within known and generally accepted guidelines and reasonable specifications. The ultimate goal is to create better-designed, more adequately specified and less costly hydraulic fill projects. The Hydraulic Fill Manual covers a range of topics such as: • The development cycle of a hydraulic fill project • How technical data are acquired and applied • The construction methods applicable to a wide variety of equipment and soil conditions, the capabilities of dredging equipment and the techniques of soil improvement • How to assess the potentials of a borrow pit • Essential environment assessment issues • The design of the hydraulic fill mass, including the boundary conditions for the design, effects of the design on its surroundings, the strength and stiffness of the fill mass, density, sensitivity to liquefaction, design considerations for special fill material such as silts, clays and carbonate sands, problematic subsoils and natural hazards • Quality control and monitoring of the fill mass and its behaviour after construction. This manual is of particular interest to clients, consultants, planning and consenting authorities, environmental advisors, contractors and civil, geotechnical, hydraulic and coastal engineers involved in dredging and land reclamation projects.

Offers a standard method to establish the capital and related costs of various types of dredging plant and equipment commonly in use. This book is divided into sections such as: introduction; description of the most common dredgers and dredging equipment used; a summary of the principles of cost standards; and cost standard tables.

Changes to the work on construction projects are a common cause of dispute. Such variations lead to thousands of claims in the UK every year and many more internationally. Liability for variations is not only relevant to claims for sums due for extra work but this is also an important underlying factor in many other construction disputes, such as delay, disruption, defects and project termination. This is the first book to deal exclusively with variations in construction contracts and provide the detailed and comprehensive coverage that it demands. Construction Contract Variations analyses the issues that arise in determining whether certain work is a variation, the contractor’s obligation to undertake such work as well as its right to be paid. It deals with the employer’s power to vary and the extent of its duties to approve changes. The book also analyses the role of the consultant in the process and the valuation of variations. It reviews these topics by reference to a range of construction contracts. This is an essential guide for practitioners and industry professionals who advise on these issues and have a role in managing, directing and compensating change. Participants in the construction industry will find this book an invaluable guide, as will specialists and students of construction law, project management and quantity surveying.

The adverse effects of construction on the coastal and marine environment are well publicised and understood by regulators, the industry and the general public. The impact of poor working practices can be extensive, given the often sensitive nature of the habitats and the importance of this region for human activities and interests. implications is becoming increasingly the responsibility of front-line staff. This greater accountability at the site level demands higher standards of environmental awareness and education, through trained and experienced personnel who can effectively manage environmental issues with the speed and urgency that they often require. avoiding and mitigating the effects of poor environmental practice on coastal and marine construction projects. contract supervisors/resident engineers; and project managers. construction experience from the young site engineer to the experienced manager. It can also be used as a training aid or refrence book, to provide site personnel with the correct information to hand for dealing with key environmental and management issues.
