GENERAL
1-1. Purpose and scope.
This manual, intended for planners and design engineers,
presents information on water quality standards
and design criteria for water treatment processes.
This manual also establishes criteria to be followed in
determining the necessity for and the extent of treatment,
and on procedures applicable to the planning of
water treatment projects. This manual is applicable to
all elements of the Army and Air Force responsible for
the planning and design of military construction,
1-2. Water treatment proiects.
State health department, State water resource, and
U.S. Environmental Protection Agency personnel, as
appropriate, should be consulted in the early stages of
project planning regarding supply sources and associated
water treatment needs. In addition to the usual
treatment that may be required to insure delivery of
potable water, consideration will be given to the need
for special treatment to protect pipelines, water heat,-
ers, plumbing fixtures, and other equipment against
scaling, corrosion, and staining, Because of the widely
varying conditions and the many types of water, it is
not possible to establish criteria for all cases of special
water treatment. Treatment for prevention of scaling
and corrosion may not be entirely effective; and in
many cases a decision as to the necessity of special
treatment cannot be reached prior to actual operating
experiences. In general, special treatment will be provided
only in cases where a study of water analyses
and experience with the water definitely show that
there will be severe corrosion of the water system or
that severe scaling of hot-water heaters, storage tanks,
and other parts of the plumbing system will occur.
Marginal cases will be deferred and treatment provided
only after operating experience determines
treatment to be necessary.
1-3. Water quality criteria and standards.
Information on current criteria and standards for raw
and potable water are presented in appendix A.

Hydraulic Jump Type Stilling Basins for Froude Number 2.5 to 4.5
Author: NANI G. BHOWMIK Title: | Size: 1.01 MB | Format:PDF | Publisher: STATE WATER SURVEY DIVISION WILLIAM C. ACKERMANN, D.Sc, Chief | Year: 1971 | pages: 35 | ISBN: unknown
Title: Hydraulic Jump Type Stilling Basins for Froude Number 2.5 to 4.5.
Abstract: Hydraulic jump type stilling basins are used to prevent the detrimental effects
of the supercritical flow velocity on the stability of the channel. Laboratory investigations
were conducted for both the ordinary and the forced hydraulic jumps on a horizontal
floor in the Froude number range of 2.5 to 4.5. Data from the ordinary hydraulic jump
correlate well with the theory and other published data. A set of appurtenances (baffle
blocks and an end sill, basin L) for forced hydraulic jump was found to perform satisfactorily.
Comparison of the test data from this basin with corresponding data from the
ordinary hydraulic jump showed that the required tail-water depth can be decreased,
energy loss can be increased, and the jump can be formed in a much shorter basin. A
theoretical relationship has also been developed to predict the turbulent pressure fluctuations
in the stilling basins. Hydraulic design of stilling basins for the Froude number
range of 2.5 to 4.5 can be accomplished with the aid of the criteria developed in
the report.

From the Foreword by Rob Smith, Director of Estates and Facilities (NHS England), Department of Health
‘The built environment for the delivery of Healthcare will continue to change as it responds to new technologies and modalities of care, different expectations and requirements of providers and consumers of care. It is vital that built environment students and practitioners alike avail themselves of the best possible information to guide them in their studies, continuing professional development and the delivery of their tasks. The range is enormous from the assessment of need, planning the service delivery to design, construction, commissioning, maintenance and operation of the healthcare environment.
The book that follows addresses these areas from a blend of contributions of experienced practitioners to the descriptions of the output from recent research that moves forward the frontiers of knowledge and practice in the many areas of the healthcare built environment.
I happily commend this book to all engaged in the exciting fields of planning, delivering, maintaining and operating healthcare environments. When we get it right, we are able to do immeasurable good.’
This book helps academic researchers as well as practitioners to understand how the healthcare infrastructure sector works by addressing the crucial issue of healthcare delivery from a built environment perspective.
It explains the trends in healthcare, models of healthcare delivery; healthcare planning; the NHS building and investment programmes; the procurement process; and facilities management; financial models – including PFI and LIFT; risk allocation and partnering.
Past investigations in the area of healthcare delivery have concentrated on either the medical aspects or the design issues of buildings but Improving Healthcare through Built Environment Infrastructure is unique in considering the ‘meeting space’ of built environment technologies and modern methods of procurement with the medical and operational needs of healthcare settings.
The authors have brought together key industrialists and academics, all heavily involved in the formulation and delivery of new practices. Case studies illustrate how policies and healthcare models are implemented in practice and help identify the key challenges for the future.

Ferrari World Abu Dhabi-World's largest theme park
Ferrari World is a Ferrari themed amusement park on Yas Island in Abu Dhabi.The park is situated under a 200,000 m2 roof making it the largest indoor amusement park in the world with world's largest space frame roof. Ferrari World officially opened on November 4, 2010. The theme park is home to Formula Rossa, the world's fastest roller coaster.
Architectural Overview
Sitting beneath its iconic red roof in the heart of Yas Island, is the world’s first Ferrari theme park and largest attraction of its kind. The Park pays tribute to the passion, excellence, performance, and technical innovation that Ferrari has established over the years and represents today. To house this state of the art leisure attraction, world renowned architectural firm Benoy created a building to reflect the sinuous form of a Ferrari, directly inspired by the classic double curve side profile of the Ferrari GT body.
Due to the shape of the island and the position of Ferrari World Abu Dhabi in close proximity to the airport, the building was conceived as a very simple ‘ground hugging’ form, peeling up from the landscape in flowing lines like a red sand dune. The visually distinctive form and shape crowns the Yas Marina Circuit and due to its location, the sleek shape and beauty of the building can be experienced by anyone driving past or flying over the Island. The building is a true architectural expression of the values of the Ferrari brand itself.
The iconic roof of Ferrari World was designed by Benoy Architects. It is modelled after the side profile of a Ferrari GT. Ramboll provided the structural engineering, masterplanning and urban design, geotechnical engineering and the facade engineering. The roof has a total surface area of 200,000 m2 with a perimeter of 2,200 m. The theme park, measuring 86,000 m2 , is located under this 50 m high roof. These factors make Ferrari World the largest indoor theme park in the world.
A Ferrari logo adorns the roof of the building and measures 65 m by 48.5 m - the largest Ferrari logo ever created. 12,370 tonnes of steel has been used to support this roof.The centre of the roof is marked by a 100-m glazed funnel. The structure was declared completed on 29 October 2009.

The issue of missile impacts on concrete containment buildings (CCBs) of nuclear power plants (NPPs) was subject to intensive research for the first time in the 1970s and early 1980s. During that period a number of missile impact tests, even on a large scale have been carried out, most notably the Meppen Tests in Germany and the Tests at Sandia National Laboratory in the USA. In both tests soft and hard missiles were impacted on large reinforced concrete slabs resembling the CCBs of NPPs build at that time. In parallel quite a number of computational analyses have been performed to predict the results of these tests. For these analyses either empirical formulas or relatively coarse finite difference (FD) or finite element (FE) models even with load curves were used. Due to the limitations of these models the possibility to predict the outcome of missile impact tests was quite difficult. Today quite a number of advanced computational methods and methodologies are available for impact analyses and as a result the issue of missile impact testing has reached a significant level of interest inside the nuclear community again.
