BS 1427 describes methods for the analysis of industrial and other waters. These methods can be undertaken outside of the chemical laboratory, for example on-site tests. This guide is for testing when the purpose of the test is to characterize the water under test for quality or process control purposes. The test methods are simple procedures for use by a trained analyst or by an individual that has had appropriate training.
Since 1993, many industrial laboratories have been shut down and the use of on-site methods increased significantly. Non-analysts using proprietary test-kits carry out a very significant proportion of these tests.
This revision of BS 1427 contains updates to specific methods since the previous standard and provides guidance on the use of the much wider range of available commercial test-kits. Since 1993, the range, type and quality of commercial test-kits/apparatus have improved. The improvements include significant benefits in terms of increased reliability and ease of use for on site testing. The use of pre-packaged chemicals and reagents has also reduced health and safety risks associated with handling chemicals and enhanced the simplicity of testing.
Most of the methods described in this standard apply to use on clean or lightly polluted waters which might have undergone treatment or been modified for industrial use.
The types of waters that are normally tested include:
a) Boiler waters
b) Cooling waters
c) Waters from hot water systems
d) Waters from air conditioning systems
e) Waters from industrial air washing systems
f) Potable waters
g) Ground waters
h) Surface waters
i) Process waters
j) Swimming pool waters.
Who should use BS 1427?
Water industry samplers and analysts
Environmental and water treatment consultants

Ark Hotel Construction time lapse building 15 storeys in 2 days
Size: 0.01 MB
This video shows an spectacular building erection in just 2 days!
The main issue of this post is open a discussion about the importance and efficiency of planning! full and complete planning from design, through manufacturing prior pre-assembly, logistics and erection.
Of course, this is not a building built in 48 hours, but certainly had more than a year of planning and work.

I would like to check with you is there any particular reason that you do not allow people to edit their post?
I uploaded my very first file to contribute to the community, but from time to time I will receive feedback from user that there are something missing from the installation package or the link is dead after some time.
By having the flexibility to update the post we can easily update and consolidate everything rather than keep giving new post with new mirrors which makes the topic looks long and people have problem identifying which link is the correct one.
Thank you
And I seem not able to PM any Mod to ask them to change / update my links... :(

hi.. can some one help me with this paper
1- Naaman, A. E., and Siriaksorn, A., “Reliability of Partially Prestressed
Beams at Serviceability Limit States,” PCI Journal, Nov.-Dec. 1982, pp. 66-85
Can anyone please give me a link to download this book : " Model Building in Mathematical Programming, 4th Edition by H. P. Williams" in PDF format (not html !)
Quarterly Journal of Engineering Geology & Hydrogeology; August 2010; v. 43; no. 3; p. 321-331; DOI: 10.1144/1470-9236/08-003

This book is the first of its kind in presenting international guidelines for seismic design. The provisions reflect the diverse nature of port facilities. Although constructed in the marine environment, the port facilities are associated with extensive waterfront development, and provide multiple land-sea transport connections. The port must accommodate small to very large vessels, as well as special facilities for handling potentially hazardous materials and critical emergency facilities that must be operational immediately after a devastating earthquake.

hi engineers i hope to help me with these paper that i needed :
1- Naaman, A. E., and Siriaksorn, A., “Reliability of Partially Prestressed

PROCEEDINGS OF THE FIFTH INTERNATIONAL CONFERENCE ON ANALYSISOF DISCONTINUOUS DEFORMATION, ICADD-5/BEN-GURION UNIVERSITY OFTHE NEGEV/BEER SHEVA/ISRAEL/6–10 OCTOBER 2002
The objective of this ICADD-5 is to focus on the application potential of discontinuous analysis methods tothe stability evaluation of structures in rock, including both modern engineered rock slopes and undergroundopenings, as well as ancient monuments in fractured rock. Nevertheless, this proceedings volume also containsoriginal, high quality theoretical papers which explore issues such as fracture mechanics modeling in the new manifold method, continuum models with microstructure for discontinuous rock mass, coupled thermo-hydromechanicalprocesses in fractured rocks, and recent developments in three dimensional DDA.
