NEWLY DISCOVERED CONCRETE CAN CLEAN IT SELF OF ORGNIC AD INORGANIC DIRTS


NEWLY DISCOVERED CON
CRETE CAN CLEAN IT SELF OF ORGNIC AD INORGANIC DIRTS
Self-cleaning buildings and pollution-reducing roadways: These may sound like futuristic ideas, but they are the realities of some of today’s concrete. Recently introduced formulations of cement are able to neutralize pollution, turning harmful smog into harmless compounds that can be washed away. Anything made out of concrete is a potential application as these cements are used in the same manner as regular portland cements.

TOP FIVE REASONS WHY YOU SHOULD CONSULT A QUANTITY SURVEYOR

TOP FIVE REASONS WHY YOU SHOULD CONSULT A QUANTITY SURVEYOR


Image result for download niqs logoA Quantity Surveyor (QS) is a professional working within the construction industry concerned with construction costs and contract Administration.

Services provided by a Quantity Surveyor include: Construction cost estimating and budgeting, Cost planning and commercial management during the entire life cycle of the project from inception to completion. Others include, procurement advice, procurement management, project management, Value engineering etc.

You need to consult a Quantity Surveyor for one of the following reasons;

1.    IGNORANCE IS DANGEROUS: It is of utmost Importance and even stressed by The Lord Jesus Christ in the bible that; before you embark on a construction project, you must count it cost to know if you have enough money to complete it. The fact that you have N10, 000,000.00 in your account and can have a reliable monthly income is not enough to embark on just any size or quality of building that you deem fit or as designed by an Architect or even a local Draftsman. Common planning courtesy requires that you think of how much can transform the Architect’s imaginations into habitable reality. The Quantity Surveyor is your best man in doing this.

METHODS OF JOINING PLASTICS


MECHANICAL FASTENING
Screws, Bolts and Rivets

Molded-In Threads

 Self-Threading or Self-Tapping Screws
 
 
 

 Thread-Cutting
 Thread-Forming


WHY STAINLESS STEEL IS PREFERRED PLUMBING MATERIAALS

MATERIAL BENEFITS
  • Stainless steel has a very low general corrosion Rate in water and no corrosion allowance is   required.
  • It can withstand very high pressure flow rate in excess of 40m/s.
  • Combining corrosion resistance with high strength allows reduction in section diameter, wall thickness and weight, making it quick and easy to install.
  • It is ductile and usinf the appropriate tooling is not difficult to bend and cut.
  • Stainless steel pressfittings, in particular are easy to use for joints and I deal for installation in areas with l
    imited space and access or where the use of heat would be a problem.

Arc Weld - Tutorial

 Arc Weld - Tutorial

This tutorial is intended to offer practical advice to beginner arc welders. It was produced with a great deal of help and guidance from professional welders whose time was funded by forum members and supporters.     Take the tutorial slowly and practice the work covered on each page before moving onto the next.
Arc welding (short for Manual Metal Arc (MMA) welding and also known as Stick and SMAW) is a very involved subject and we only cover enough to get you up to speed. There are many books on the subject, and more detailed information can be found elsewhere on the internet. Also we have a very friendly forum that can help.

Arc Welding Safety

As with any other electric welding process, skin and eyes need to be properly protected from UV light. Electric shock, fumes, burns, and fire are other risks.
The safety page discusses how to minimise these risks.
Arc welding safety

Starting the Arc

The arc is started by touching the electrode momentarily against the work to complete the electrical circuit before raising the electrode to establish the arc.
'Tap starting' and 'scratch starting' are the two common methods of starting the arc. Which one to use is a personal preference, and can be influenced by rod and welder type.
Starting the arc

Rod Position, Arc Length and Movement

Rod angle, arc length, travel speed and welding motion are illustrated with photos  shows the effect of varying the arc length.
Rod angle, arc length and motion

Arc welding faults

When learning any new process you'll likely start off doing things wrong. Profiles and sections of welds with various faults are compared with good welds on this page.
The faults covered are incorrect travel speed, incorrect arc length, and incorrect amps.
Arc welding faults

Flat Joints and Joint Preparation

Arc welding is especially suitable for joining thick material as cold joins are easy to avoid. That makes it possible to tackle thicker material using multiple passes of weld.
Flat Joints and joint prep

Buying an Arc Welder

For most people a DC inverter is the best type of arc welder to go for. They have many advantages over the older types, but can fall down on repair costs and longevity.
The page covers what to look for in inverter welders and other types of arc welder.

NEWLY COMPLETED BUILDING COLLAPSE IN OSUN STATE



The collapsed building
Residents of Ejigbo town in Osun State were on Wednesday woken up by the noise of the structure which collapsed at the newly completed Ejigbo High School.
Our correspondent gathered that part of the school which had been completed and ready for inauguration collapsed at around 5.30am.
Some persons were reportedly injured, but there was no death recorded as the structure had yet to be occupied by pupils.
Governor Rauf Aregbesola had on Tuesday at his campaign rally in Ede listed the new school as one of the most beautiful schools in the country.
The administration built the school following the introduction of school restructuring by the incumbent governor.
The Public Relations Officer of the Nigeria Security and Civil Defence Corps, Mr. Ayo Olowe, told our correspondent that the building collapsed around 5am.
The Police Public Relations Officer for the state, Mrs. Folasade Odoro, said the school building came down due to heavy wind.
She said that the preliminary investigation by the police revealed that the building collapsed following a heavy wind on Wednesday morning.
She said, “The building collapsed due to heavy wind which blew this morning. Two artisans laying tiles sustained injuries. They were treated and have been discharged.”
The governor, while reacting to the incident in a statement issued by his media aide, Mr. Semiu Okanlawon, said, “The Government of the State of Osun regrets to inform members of the public about the suspect incidence of the collapse of the main hall of the newly completed ultra-modern Ejigbo High School.
“Information at the disposal of the government indicates that the main hall which had been completed along with other classrooms of the school came down at about 6am Wednesday after a loud bang.
“As a responsible government, it is too early for us to say what the exact cause of the collapse is until we have full investigations and advice of professionals.
“However, it must be stated here that all necessary quality assurance tests were carried out to ensure structural durability and integrity of the project.
“Engineers from the Osun Ministry of Works and engineers from the Structural Engineering section of the Nigerian Society of Engineers have been dispatched to the site to establish the real cause of this unfortunate incident.”

BUILDING COLLAPSE NOT CAUSED BY 32.5% GRADE CEMENT

Cement Bags
Lafarge Cement Nigeria Plc has debunked reports blaming the 32.5 cement grade for building collapse in the country.
The company’s managing director and chief executive officer,  Mr Joe Hudson, said this at a press briefing in Lagos, yesterday.
He said the use of the 32.5 cement grade was not responsible for building collapse, pointing out that building collapses are caused by the use of unqualified workmen in construction activities, absence of building codes and professional procedures, greed of some contractors to cut corners and sometimes national disasters.
“This clearly demonstrates that the use of 32.5 cement grades or any other cement grade is not responsible for building collapse and there is also no substandard cement in the country. We are the first to start a national building dialogue to address the real cause of building collapse. We published a book and we also had a national discuss about this issue in April and had a lot of stakeholders in attendance to find out reasons for building collapses in the country,” he said.
 

FEDERAL GOVT INTRODUCES NEW TECHNOLOGY TO STERM BUILDING COLLAPSE

Addressing Housing Deficit In Nigeria

Addressing Housing Deficit In Nigeria  print


By Lilian Chukwu

By some accounts, Nigeria’s home ownership rate, currently put at 25 percent, is very low when compared with the housing situation in some developing and developed countries.
Available statistics show that Benin Republic has home ownership rate of 63 percent; Kenya 73 percent; Singapore 90 percent; the U.S. 70 percent; South Africa 56 percent, and Libya 41 percent.
Commenting on the housing situation in Nigeria, President Goodluck Jonathan said that the country needed a minimum of N56 trillion to be able to bridge a deficit of 17 million housing units.
He said that the shortfall, which did not cover the cost of providing infrastructure, translated to an average cost of N3.5 million per housing unit.
Housing experts note that the housing deficit has continued to increase; saying that the development indicates that the government’s housing policy is not working as expected.
They note that the deficit rose from seven million housing units in 1991 to between 12 and 15 million units in 2008, while peaking at between 17 and 18 million units in 2012.
They insist that the deficit would continue to rise until the financial authorities are able to bring down interest rates to a single-digit level, so as to enable low income earners access mortgage loans.
Mr Gimba Ya’u Kumo, the Managing Director, Federal Mortgage Bank of Nigeria, said that something urgent must be done to bridge the housing deficit.
“If nothing is done, there will be an estimated homeless population of 24.4 million people in Nigeria by 2015,” he said.
Mr Chudi Ubosi, the Chairman of Association of Estate Agents of Nigeria (AEAN), blamed the poor housing delivery in Nigeria on the short mortgage tenure system in the country.
According to him, only a few primary mortgage institutions in the country give mortgage loans that are repayable beyond 10 years.
Ubosi also described the 17 percent interest on mortgage loans as very high, as against three to five percent charged in developed countries.
“The financial institutions in the country offer loans not mortgages. This is because mortgage tenure, as practised in many countries, is beyond a minimum of 20 years.
“In other countries, mortgage is given out at low interest rate but in Nigeria, those who need mortgage cannot access it,” he said.
Ubosi said that the high mortgage interest rates had discouraged many investors and Nigerians from aspiring to own their own houses.
He suggested that mortgage loans should be given out by mortgage institutions at single-digit interest rates.
However, Mr Olayemi Shonubi, the Chairman, Nigerian Institute of Quantity Surveyors (NIQS), said that government could bridge the housing deficit by encouraging a pragmatic partnership between the public and private sector.
He suggested that individuals and organisations should be encouraged to come together to form housing cooperatives, as part of efforts to boost housing delivery.
Shonubi, however, advised the government to make land available to estate developers across the country in order to accelerate the construction of affordable houses.
Sharing similar sentiments, Prof. Timothy Nubi of University of Lagos identified difficulties in acquiring land as one of the factors responsible for the housing deficit in the country.
He said that the Land Use Act of 1978, which should have been an instrument of addressing land ownership and titles, turned out to be counterproductive.
He stressed that problems encountered in title transfer and registration in Nigeria could be traced to perceptible defects in the Land Use Act of 1978.
Nubi said that under the Act, only the governor of a state had the power to issue a Certificate of Occupancy.
“This would have been okay if not for problems associated with time wastage, expensive processing and endemic corruption which undermines property transaction and investment,” he said.
Nubi also underscored the need to reduce the costs and bottlenecks in efforts to obtain title documents.
“The governors’ consent for transfer of title should not be more than one percent of the value or cost of the property.
“The processing time for title registration and governors’ consent should not be more than 15 days.
“The practice of asking for numerous supporting documents such as tax clearance, development levy, tenement rates, should be entirely removed as a requirement for the processing of title transfer.
“Government should also deploy more human, financial and technical resources to man the processing offices so as to curtail bureaucracy and reduce the level of corruption associated with it,” he said.
All the same, Mr Chucks Omeife, the former President of Nigerian Institute of Building (NIOB), urged the government to check the rising cost of building materials.
He said that the increasing cost of some building materials had discouraged investors from investing in the construction sector and low income earners from building their own houses.
“The development of our housing sub-sector may be hampered if the prices of building materials continue to rise unchecked because the cost of iron rods, window and door frames and other building materials are all escalating,” he added.
Omeife, nonetheless, appealed to the government to subsidise the prices of building materials so as to boost activities in the real estate sector.
He particularly stressed that low income earners would gain a lot from government’s efforts to reduce the cost of building materials.
All in all, housing experts agree that one of the pragmatic ways of redressing the housing deficit in Nigeria is to make building materials affordable to the less affluent members of the society, who constitute the larger percentage of the population.

Photo: Thai Snake Girl Attracts Loads Of Tourists


 
8 year old Mai Li Fay, from Bangkok, is far from living the usual life of a girl her age. Everyday, thousands of people gather to the front of her family’s house to get a chance of seeing and possibly touching the young girl, a gesture which both buddhists and hindu pilgrims seem to perceive as a garantee of good fortune.

According to the country’s top medical expert, Dr Ping Lao, the young girl suffers a very rare syndrome known as the Serpentosis Malianorcis  or Jing Jing’s disease, which gives her lower body a distinct reptilian form and aspect. Only a handful of such cases have been recorded throughout history, so the scientific knowledge accumulated about the pathology is rather limited and there is no cure in sight at the moment.
