seems you stopped the phase by phase analysis of cost sir

I'm currently away in Suleja (Niger state ) for the sallah break.... i will soon be back

Please i need roofing quotation for building of size 47 ft by 42 ft .

Long span Aluminum roofing sheet proposed with 10 ft k post.

Send details to my email . strongwilllead@gmail.com

can you send the roof plan here

ajebuter:
What virtue are you even talking about sef?!
Under that veil and hijab hides the ashiest olonshos, witches and sluttiest babes in the north.

Ask any male corper that served in the north and they will tell you how slutty these hijab babes are.
Some are even worse than our mini skirt and scantily dressed southern olonshos.

Virtue my foot!

over generalization is bad and prejudice is a big problem. hijab is good and is sanctioned by Islam for women. My mother, sisters, and wife where it and they are peace loving Nigerians, infact millions of peace loving Nigerians from North, south west, Edo etc where hijab and go about there normal business from day to day.

Its quite unfortunates that some misguided and enemy of progress have decided to start using it to cost trouble. The need to checkmate their activities required we banned it for this period.

Samunique:
U are very bias, if u say GEJ messed up Nigeria in 6yrs what of your brothers up north who ruled for more than 30yrs?

I think u need to change this ur foolish mentality.

Infact i smell bigotry in your head.

what foolish mentality ?
some people might have criticise Jonathan heavily because of his ethnicity or religion but I was never part of that team. JEG was simply not good for the job.

He was not proactive and never really work hard to tackle our insecurities issues.
He allow corruption to kill Nigeria economy
He encourages nepotism and religious discrimination in his administration.

kashrush:
Obviously not a Muslim to say such. If your sis happen to use I jab would u mistake her for boko?

That is the problem...any one with a contrary idea from yours must either be a non Muslim of week Muslim. Islam is a beautiful religion with more than 1.7billion followers world wide, extremism is a problem that majority of Muslim world wide is trying to fight and put an end to but extremist and hypocrites who hide under it for political and personal gains will not allow us to get solution to it.

Indonesia is the largest Islamic country on earth with more than 250million Muslims yet education is a priority in the java nation, Malaysia is a string Asian tiger nation with more than 75% Muslim...these are great nation. You need people to be alive to worship the Almighty Allah, you need technology to build better home, society and technology to defend the suppose muslim population.

Ban the use of clothes that may expose Nigerians to terrorist attacks in this crises period, ban almajiri, ban street hawking and send all young children to school to learn

Ayameze2015:
Over here in adamawa state muslims loaded in each vehicle returning from ''hawan idi'' (prayerground) are chanting ''ALLAH TSINE MAI MALAFA, MUN JE MUN DAWO LAFIA'' meaning (may God curse Jonathan, we have prayed and return safely) these guys are senseless!

Don't mind those gullible illiterates... Jonathan was a very bad president but they need to face the reality on ground which is boko. Boko is a product of poverty, illiteracy, intolerance, corruption and religious fanaticism.

fkpboss:
After thorough observations, I hereby conclude that Buhari 3 months old administration is worse than jonatnan 6 years

stop this your stupidity and let the President work.
Nigeria is in serious trouble because we have too many slowpokes and mentally challenged people who only think about ethnic and religious sentiment.

Nigeria was literally messed up by Jonathan administration give him time and he will get things done

Sunymoore:
Take me out Islam bro.. You don't understand what I mean, I don't take any woman wearing Hijjab as Boko, but I'm no longer comfortable with them, because you can never tell, take it from someone that have first hand experience..

even in far away Niger state people are cautions....we need to do away with that for now...the problem is everything is political in Nigerians and the ulamas are not really helping matters

ok sir... we will get back to you sir

AreaFada2:
You're correct. That was the mandate of poly & mono-technics.
But where is the electricity for artisans industry??

So instead polys/monos now compete with university degree holders for equality to work in banks and so on.

Usually, mostly those who don't make university grades or don't have long leg go to polys.

Even if you train OND electricians and carpenters, they would end up looking for office jobs.

Better have an educated population than an uneducated population. Even if just for the sake of it.

Many brilliant ones will get jobs abroad. Like 9ja doctors doing well abroad.

I think the trend is changing now, people want to have soft skill because white colar jobs are.not readily available. People are learning skills like computarized auto mechanics, furniture making, building construction etc.

The population is big, market is huge, skill is what is required to live in this country. with anti corruption properly in place civil service job will become unattractive

eddyj36:
I rep Unilorin.. Better by far ..107k is too much really and the school will not admit more than 5k entries 6k at most. So over 100k to be disappointed ... We need more schools in Nigeria.

I think we need to make rooms for more technical base and engineering education. You obviously need more artisans and technicians than engineers and technologies, the current situation where everyone wants to go to the university is not encouraging.

A third world country like ours need to train more artisans and technicians to help us in our industrialization drive, mining and agriculture

tollyson:
Well done Abdul, please how much will it cost me to build a 3 bedroom flat?

5 -7million

written:
ok. Long story short, i studied civil engrn.questions are? Where do i start from if i want to go into civil start practice? Do u think it is worth the time learning from builders where u dont have engineers? Thanks peep. Dont mind my previous writeup '2much mucuh'.

Civil engineering is a very diverse and wide discipline, depending on the area you really want to specialized.
we have structures, highway engineering, foundation engineering, hydraulics, project managements, irrigation and water resources etc.

structural engineering enables you to work with architects on building and other discipline on building projects, your role depend heavily on the complexity of the job structural. The more structurally complex the job become the more your involvement.

To the main issue at hand, building construction is purely a building technology job, we structural engineers do the consultancy work but due to too much overlaps like our good understanding of materials property like concrete, steel, wood, polystyrene etc, and our better understanding in analysis and mathematics, we tends to do better as a builder if we are ready to learn.

what you really need to know are as follows:
1.Learn how to interpret architectural, structural, mechanical, and electrical drawings on a building project
2. Learn how to read tape (linear measurement from measuring instrument), know the difference between 'metric' and 'imperic'
3. Learn how to do setting out with profile board
4. Learn how to batch concrete, mix ratio etc
5. Learn how to prepare quotation and bill of quantities
6. Learn how to do project schedules and job planning.

The title 'engineer' is overburden and very misleading. Learn as much as you can from artisans ( carpenters, masons, iron benders, electricians, etc). learn from other professionals like architects, civil engineers, building technologist, surveyor etc.

Thanks & God bless for the response sir. But can one also use headbeam for steel roofing?(Lattice) Or it's both combination of headbeam & columns? Pls what is the difference btw sancrete & vibrated blocks? Thanks.

You can use head beam for steel roof. Its always better for the steel truss to be placed ontop of the columns direct because if place out of column position it will create or constitutes point load which will increase the bending and shear on the head beam.

The arrangement should be done by the structural engineers at the designing stage....It is better to project reinforcement from the column out of the head beam to serve as the connector (connect roof truss to the building), when the roof truss fall on the beam directly a shear connector is placed on the roof beam before casting.

sancrete block is a vibrated block (mainly hollow) produced from the combination of cement and fine aggregates (sand). it is sancrete because of the absence of coarse aggregates (gravel, granite etc). sancrete is produced with a mix ratio of 1:8 and with a compressive strength of between 0.5-4N/mm2.

laplace19:
Sir Abdul, thanks for taking your time to type this.. it's becoming interesting and believe me, the reason why I want both of us to tackle this is because you are a first class brain..... now to the matter, One thing I understand about your own method of using different densities of cement, sand, and gravel is that it works best for Standard mixes (1:2:4, 1:3:6,etc) due to incorporation of 25% for wastage and shrinkage .

I recently carried out a final year project with a design mix of 1: 1.38 :2.35 for a target strength of 38.20N/mm2 for 12 cube moulds, 12 beam moulds and 12 cylindrical moulds with total volume of 0.26614m3...
Now, using the density of cement gave me a number of 1.69 bags (approximately 2 bags of cement).... Also, using the "wet density of concrete of 2410kg/m3" which I got from my design mix gave me a number of 2.71 bags (approximately 3 bags)..... now after carrying out this project of mine I used about 2.8 of the 3.0 bags I bought...

Again, using different densities of cement, sand and gravel for a mix ratio of 1:2:4 will alter the mix ratio to 1:2:6 from your calculation which goes thus :

Cement(5bags):sand(0.5ton):gravel(1.5ton)
250kg : 500kg : 1500kg
1 : 2 : 6

since the 1:2:4 is a STANDARD MIX (which the labourers will work with as 1 bag of cement, 4 head pans of sand and 8 head pans of gravel) it won't be affected, but when it's a DESIGN MIX it will be greatly affected thus reducing the compressive strength.
I have compared the two methods (ie using different densities of the constituents and the wet density of concrete) using a 150 x 150 x 150mm cube, cured for 28 days and crushed in the laboratory using a compressive testing machine and that of "wet density of concrete " gave the desired strength.

I know you will be too busy now to try this and compare..

please can i have a copy of your thesis ?

snakebeat:
Sir is head beam course necessary for buildings to be roof with timber? Or does it play another function apart from receiving roof members? Thanks.

head beam is necessary but not a a must have...if you can afford it its better to have head beam atleast on the exterior wall.
these are the functions of head beam
1. it help to receive the roof truss, especially in winding area
2. it serve as ring beam to tie the building at the roof level, this helo to avoid cracking due to excessive loading on the walls.

laplace19:
Oga Abdul..... you are always on point. In fact, I don learn many things from you and I am willing to learn more....just that my phone bin crash so I no come follow this post on time.

Please eeh, check that ELEMENT 3... sum of mix ratio is 10 (1:3:6),I know you mistakenly used 9... Also, when determining the Number of bags of cement, tonnes of sand and gravel, I think what we should be multiplying with should be the "wet density of concrete " which ranges from 2400-2500kg/m3(Generally, most people use 2400) depending on the mix ratio and the characteristic strength of the concrete and not the density of the materials(cement, sand, gravel)... Please, check it out and give me feedback,cos I will really appreciate . A layman in Civil Engineering may not understand my point, but as a guru you are am sure you gonna understand.

thank you for that arithmetic correction my brother.

with regards to the quantity of constituents materials, I am of the opinion that their respective density is the major determinant of their quantity in cement. For example, for a cubic of concrete when wet, the only material that is lost after setting and hydration process are water, void and to some extent heat ( this doesn't occupy much space). this materials especially water are also constituents and their weight need to be determine prior to mixing.

concrete tense to shrink after setting ( harden) due to loss of moisture (water) content using the relative density of concrete will not give us a through reflection of the quantity of the constituent materials.

Assuming we want to produce one cubic meter of concrete using 1:2:4
a volume of concrete will have the followings constituents
1. 1/7x 1 = 0.143m3 of cement

2. 2/7x2 = 0.286m3 of sand

3. 1-0.143-0.286 = 0.571m3 of gravel

4. 0.55x143= 77liters of water

small increase of 25% can then be allowed to cater for increase in volume due to shrinkage and poor handling of concrete.

since it will be impossible to go to the market and get these materials in unit such as m3, you will need to convert them to unit understood by trade men. Language such as bags, tonnes and liters comes to mind.

to convert the quantity of cement in volume to weight you need to know the density of THAT MATERIAL because of the relationship between them is: density = mass/volume

thus; cement requires becomes = 0.143 x 1506/50 = 5bags (aprox)
sand is been sold in tonnes, quantity of sand = 0.286x1.6 = 0.5tonnes (aprox)
gravel also comes in tonnes, quantity of gravel =0.571 x 2.4 = 1.5tonnes of gravel (aprox)

note where, 1506kg/m3, 1600/1000(tonne), and 2400/1000(tonne) are the density of cement, sand, and gravel respectively

disumusa:
must there be prostitude or armrober if one woman give birth to 15 children in order to have more money and you can't train or feed them whose problem is that?

Armed robbery, prostitution, child labor and abuse ( almajiri, servitude etc) etc are all social problem that is affecting Nigeria as a nation. Only almajiri is peculiar to northern Nigeria while all others affect every region of Nigeria.

Over population is a big problem that need to be tackle, the problem is we get emotional due to religious believe when such is been discuss. I believe people should give birth to children they can provide shelter, clothing, food and education for. Parents should be arrested for allowing their children begging or hawking

disumusa:
begging is better than stealing.

begging is disgracing when able men that can work either in farms or labor work go to the street to beg. Begging is a social problem that need to be eradicated by enlightenment, jailing of offenders and banning it completely

peaceland:
well done sir,
patiently waiting to see how 2m will cover the finishing stage,
I agree with all other stages but still cracking my head on how the 2m finishing will work for tiles, wiring, fittings, kitchen, wardrobes, bathroom fittings, painting, phcn meter, doors.
Also seems no provision for fence
Thanks a lot for the education so far sir

The fittings includes the following
1. plumbing work, which will be in two stages. piping of water distribution/waste system, and fittings.
2. Wiring work is expected to be a full conduit type in three stages: piping work, wiring and fittings
3. Plastering work of all the rooms and external walls: the plastering is expected to be 12.5mm thick ( 1/2'') with a mix ratio of 1:6
4. the tiling work will cover the whole area with a screed of 50mm (1:6), tiles of 450 x 450mm, toilet tiles of 300mm x 300mm
5. Aluminum sliding window of 1500mm x 1200mm, 1200mm x 1200mm, and 600mm x 600mm. all the windows with inner net.
6. Chinese doors: entrance of 1200mm x 2100mm ( iron door), 900mm x 2100mm (exit iron doorr), 4 number of 900mm x 2100mm wooden panel door, 4 number of 750mm x 2100mm wooden panel doors
7. Painting work

Note: excluding compound interlocks, furniture's such as kitchen cabinets, wall wardrobes, fence, entrance gate, security house etc

here is what i finally come up with

keyzid:
Ok. Now that he has banned beggars, what measure have he put on place to house and support these beggars? Or he wants them to start feeding on airs and his urine.

Begging is a disgrace to humanity, they should be ban for life

Idrismusty97:
If you reject the plants in your zone you should as well reject the megawatts.

idrismusty you talk and reason like my friend from katsina.... you always on point

abouzaid:
i think you intended to say that the sandcrete are of lower quality. renting a vibrating machine to produce your own blocks on site would solve that since you can then mix it to be strong. in my own thinking columns are nice but not necessary a must in a dry area not prone to environmental hazards like flash flooding.

you are on point sir...most sancrete block produce here fall withing say 0.5 - 1.5N/mm2 which to me don't have the necessary strength to sustain the structure for a very long period of time compare to a weak concrete of say 20N/mm2. Column is not compulsory but adding a few will not cost much, and will surely improve structural integrity of your building

SHABZ:
Hi Abdul,

Lovely thread you've got here, learnt so much that my contractor gets scared whenever I ask questions...

I have a few questions for you based on a project I'm about to embark on:

1) Is Hardcore (boulder) required for bungalow foundation in a dry piece of land?

2) Are columns needed for bungalows that do not have parapet?

hardcore is important but building can do without it especially in areas where boulder is very expensive. Most houses here in Rivers don't have
hardcore in them. For bungalow without hardcore the laterite filling or sharp sand filling should be compacted very well manually or using a vibrator at interval of 150mm (6" and wet properly.

Columns are not necessary in bungalows because they are built on the assumptions that the partition walls are load bearer. Since, sancrete block sold in Nigeria are of lower quality it is safer and preferable to include some columns at critical span to reduce direct load on the partition walls. The cost of such columns in many cases are considerably low compare to the work they do ( check above the cost i gave for the columns in the building above)

That is the beauty of federal university of technology Minna....keep it up brother

mufutau55:
Thanks Boss. Yes. I just got your Whatsapp this morning and intend to reply...
The project is still at decking level... I am still making arrangements but also scared of the raining season. Thank you.

Hajji M.

dont be scared of the raining season sir

mufutau55:
Yes. Rising cost of materials nowadays is not a joke.. Also in Port-Harcourt, I think their soil there needed stronger foundations as the OP has constructed. Spyder880 always mentioned the water prone soil of Port-Harcourt. OP is very good at what he does.

Hajji M.

thank you sir, how about your project sir...i have been trying to get in touch sir

abouzaid:
Abdul say the truth, what's your favourite textbook in school? this is the standard way to build a house. even hurricanes and earthquakes would inflict little or no damage to it. keep it up.

Thank you sir my brother... i just learn and pick up some skills from people i had worked under in the past... i have worked under architect , building technologies, civil engineers, land surveys etc.
I actually major in civil engineering... books like advance engineering maths, hydraulics, highway engineering, engineering surveys, soil mechanics, road geometry, advance structures ( especially those on stiffness matrix )
