SUPERSTRUCTURE
This consist of the sreucture( sancrete block wall) above the foundation...
9 inches block as already been selected for the fence blockwork.
The fence would be braced with an interval of every 3m
Two number of 9inch blocks laying perpendicular to the the block wall would be used for the brace thereby providing adequate strenght( The brace is required to break the span of the wall and prevent the fence from structural failure)
With a this Information in mind, we can now estimate the total number of blocks for your fence

SANCRETE BLOCK ESTIMATION

REINFORCEMENT
Concrete is strong in comprension but weak in tension, to cather for the lapses in our concretes tensile strength we have to introduce reinforcement bars.. We have two types 1 High yield with a Tensile strength of 460N/mm2
2 Mild steel with a tensile stregnth of 250N/mm2
We have specified 4Y12 high yield for our main bars and Y8 for our links in our beam design....
To estimate the total mumber of reinforcements to be purchased-
MAIN BAR
Total perimeter of the fence = 87m
Total length of one Y12/Y8 reinforcement = 12m
Total number of Y12 = 87*4/12
= 29 number of Y12 reinforcement
Y12 Currently sells in the market for 1100 naira
LINKS
Refereing back to our reinforcement detail posted under the design stage
We are using 25mm cover( cover is the distance between the reinforcement and the outer face of the concrete it helps to prevent the reinforcement from fire, chemical attack and moisture)
The leghth of the link = 2( 225-25+25) + 2( 500-25+25)
= 1250mm
We have decided to space the links at 300mm, meaning if we divide the total perimeter of the beam by 300 we would arrive at the total number of 1250mm links.
Number of links = 87/0.3
=290 number of 1.25mm links
Total number of full length links to be purchaed ( they are produced 12m in length) =( 290 x 1.25)/ 12
=31 number of y8 reinfrocement

Y8 cost 950 naira in the market...

There is misconception in Nigeria about what constitutes a raft foundation and there are many other types of foundation that economic logic dictates we consider before settling for raft foundation.
But first things first, do a comprehensive Geotechnical test to bring to light the bearing capacity of the soild at different depts along the soil profile, The soi profile of the land, the water table.... Its only with this information and an accurate design can a proper estimate be made...
You cant just say swampy land and quote 1.5m has the suited depth of your raft...its wrong
Do a Geotechnical test

Follow this thread by harneyprojects... You can estimate the fence work yourself and negotiate on a level ground with your builder https://www.nairaland.com/3018907/fence-design-costing-constuction-harneyprojects

The role of the senate is to make bills and pass the laws on to the President to sign into law... Without the president signsture, the senate is void.....The president has the power to give executive orders which bypass the senate....Example is what Obama did recently with his new Gun legislature and Obamacare
The Power of the Senate can never be understated but its still limited

jpphilips:
Because Mujaheddin received training to resist Russia occupation means the west laid the foundation for terrorism? So because the Nigerian army officers receive training at Sandhurst, they are free to become terrorists right?
where are thy brain oh ye Nigerian youth?

The same Mujahddins lead by Osama bin ladden, the exact same people developed into alqaeda and attacked the US, Kenya , UK and other countries. Alqeada metamophised from a terrorist group into an Idea, an Idea that laid the foundation from ISIS, Bokoharam,Al nusra, Al shabab ......Believe me, the worst thing to fight against is an Idea, you can kill a person but the Idea would spread an live on in other people...

The double standard of the west is so irritating... The screem about human rights when it favours them, they screem dictatorship when it favour them, they screem corruption when it favours them.
The worlds terrorism problem was started by them, they were the once who armed and trained Alqaeda to fight the soviets, they armed and trained ISIS to fight Al-Asad...they destroyed libya completly.....they accuse china of spying when the CIA and NSA does far much more.....
One day the oppresors would become the oppresed

Newtons first law of motion... A body at rest would not move inless force is applied....
The politicians, The Buhari, the Jonathans, The Sarakis of Nigetia know we are timid and stupid..Nothing would happen in this country unless we make it happen..

Nigerians need koboko to reset our mentality by force, in civilised societies Questions are alresdy being asked and the countires tax agencies are already investigating to see how much they can recover but In Nigeria and Africa most people dont understand what all this means, the onve that understand are asking stupid questions like "why is APC after Saraki" or "how does it affect us".... We need an agency that would be resposible for reseting peoples mentality with koboko, we cannot move forward like this..

Malakh:
that's the work of a demon,not some science crap,he is the author of confusion

Like seriously? You realize this is 2016 not 1500BC... Going by your assetion it means you would call the southAfrican doctor who transplanted a penis from a dead donor to a living recipient a Mini-God? All this nonsense talk is because we live in an underdeveloped society if not they would medicaly fixed his problem and given him a normal life

Integrityfarms:
What does APC really want from Saraki??

Stepping down as Senate president? A mission impossible!

In Iceland, there is mass protest going on for the PM to resign because of the #panamleaks but in Nigeria we blame APC or PDP for witchunting... Smh

FOUNDATION

EXCAVATION
The excavation of the site is billed per meter along the perimeter of the site. The perimeter of the fence is estimated to be 87m ( the length of the gate was subtracted from the perimeter of the whole site to arrive at this figure)
The labourers charge between 500-600 naira per meter depending on location. For Awka they charge 600naira
The Total cost of the excavation = 500 x 87
= 52,200 naira
CONCREATE WORK
Concrete is a building material made form the mixture cement, fine aggregate (sand), course aggregate ( gravel) in a mixing medium (water). The various constituent are mixed in a specified ratio. 1 (cement );2 ( sand) ;4 (Gravel) is the mix ratio for this job
The volume of the concrete is estimated by multiplying the length of our RC beam(Perimeter of the fence) X the Depth of the beam X the breath of the beam
Volume of concrete = 87 x 0.225 x 0.5
=9.79m3
The value obtained has to be increased by 25% to cater for concrete shrinkage and wastage during casting
Actual volume of concrete = 1.25 x 9.79
=12.24m3
Cement
The volume of cement required to mix 12.24m3 of concrete is obtained from the specified ratio 1;2;4
Volume of cement = 12.24 (volume of concrete) x 1 ( ratio of cement in the mixture) / 7 ( total ratio of the constituent concrete materials)
= 12.24 x 1/7
= 1.74 m3
The volume of cement we just obtained has to be converted into a unit you can use to purchase cement from your local supplier( They supplier in 50kg bags of cement)
There is a mathematical relationship between density, volume and mass
where Density = mass/ volume
And the density of cement has been obtained through laboratory experiment to be 1506kg/m3
therefore Mass = Density x Volume
= 1506 x 1.74
= 2620kg
A bag of cement is 50kg
Total number of bags required = 2620/50
=53 bags of cement

It actually dropped to 0mw three times during the last 7years...not defending or supporting anybody, just pointing out something

Olodo, rather than concentrating your efforts to acquire tangible knowledge, you are here talking nonsense about a topic you know nothing about..
For your personal enlightment, OPEC Secretary General is different from OPEC presidency......
I believe statistically speaking, Buhari favourites the northern part of Nigeria more than the rest(although North and South are imaginary divisions) in appointments but I don't mind him appointing a Ghanaian has minister of power. I just want 24/7 electricity.. Even if he appoints someone from Edo state I doubt if it would affect me in anyway personally..

Fence Costing
The three cardinal pillars of Civil engineering are
-Structural Stability: Your structure must be structuraly sound
-Economy: It must be financially feasible to build
-Aesthetics: It should aligning towards being aesthetically pleasing but not neglecting structural stability and Economy
At Harneyprojects we emphasize a lot on the financial feasibility of a structure so has to make our middle and low income earners have the the satisfaction of owning a home and also reduce the construction time......
I would breakdown the costing into
Foundation
Superstructure
Copping
I would make it has understandable has possible so you can use the knowledge acquired to cost your own fence before proceeding to acquire the services of a contractor , thereby bridging the gap between clients and contractors.

For the foundation We decided to use a 225 x 500mm reinforced concrete beam instead of the traditional strip foundation. We decided to use the RC beam due to its high resistant to differential settlement which usually occurs over a long period of time, there by eliminating the occurrence of cracks on the fence.
-We used 2Y12 Top and 2Y12 bottom, with y8 links spaced at 300mm
-A 2ft deep foundation was selected
-Due to the sloppy nature of part off the site, A foundation step of 225mm was prescribed
Sancrete Block 9 inches hollow sancrete Block was prescribed for the block work

Harney Project? Are you involved in power project?

Our Electrical Engineering section has done quite a number of elecritrification projects for the federal Govt, plus substation construction and installation

Fence Design
For Every Project the most important and critical stage is the design where important decisions are made. Decisions like the type of fence to constructed, The size of sancrete blocks,The type of bond and The type of foundation. For an effective design.
Site visitation is usually necessary where visual analysis of the land can be carried out and in the absence of a survey drawing, the site measurement can be taken.

The HarneyProject team is poised to bring cheap affordable housing for the Nigerian Middle class and lower class while enlightening our clients on the construction process to ease the client-contractor relationship.
A fence is also part of your structure and usually encloses your building. Personally I feel traditional sancrete block fence reduces the aesthetic of your building by preventing passerbys from appreciating the full beauty of your building but due to the prevalent security situation of Nigeria it has become a compulsory part of your structure, some home owners go the extra mile by inculcating cctv cameras, electric wires, armed security guards patrolling the perimeter just to have the feeling of being safe.
We are using a Nairalanders fence project has a case study...

Congratulations.

Hajji M.

Thank you sir

My wife just gave birth to bouncing baby boy, I invite you all to come celebrate with me on Friday at suleja, Niger state. Rice and stew very plenty .....

ogenee:
Plz help, what is the standard distance to keep from the fence while electing a structure. Does it also cove that of the roof. thanks.

Depends on your status building regulation but most states prescribe 6ft by the side and back and 6m from the front fence.

LondonCool:
Thanks, I'll be in touch. How do I contact you?

Podosci47@gmail.com or what's app on 08068396895

Put the raft foundation to sit at 2.8-3.8million depending on location
The duplex stands at about 25-35 million depending on location

Ipinuoluwa:
Wow,nice stuff! Is there a way I can convert a 12 room face me,I face you to multiple structures of
this? ,

Depends on the size of the land..

-A survey drawing (showing the size of the plot, orientation of the land, access roads and other site details) done by a surveyor, would give you all the details you need to properly place your Building in the plot.
-The comprehensive client brief detailing the type of Building, number of rooms, sizes of rooms and other person preference.
-Soil test result ( for the structural engineer) to know the type of foundation
-You need to know the road level and also the water table to accurately specify the level of your DPC( damp proof course)
