ENGAGE A STRUCTURAL ENGINEER TO HANDLE YOUR FOUNDATION
Architects supervise buildings as well but their focus will be the external attractiveness and straightness of blocks etc.

Under civil engineering, we have the highway engineers, the water engineers, railway engineers and structural engineer.
For you information, a structural engineer focuses on the structural elements like the foundation, the columns, beams, slab and trusses. Whether it is for concrete or for steel.
It is painful though that so many clients focus on the external outlook only and end up giving a carpenter the work of a tailor and give a barber the work of a tailor.
Then later they start complaining that their cloths are sowed with nails and their head are cut/stitched with sewing machines.
Every professional in the building/construction industry is vital but give the right professional the work that they specialise in. And this is not something you tell everyone and his cousin to state their prices to supervise here because you will soon see N1 quote to supervise your foundation.
I am a coren-certified structural engineer

What's so complicated in supervising a two storey building?

Ok

my advise is go with the architect to have a better outcome. One of the advantages you get with the architect is coordination of all allied inputs while a structural engineer thinks in a rigid direction. A structural engineer may not position other important elements correctly such as plumbing pipes etc because he/she is not trained to do so and so many other details. if per chance a drawing revision or slight amendment is required what you get is a structural solution which may not tally with your aesthetic and functional needs. what the architect is charging is way below industry standard. for you to know an architect's fee for supervision, you should 've an estimated project cost(BOQ or preliminary estimates) and pay the architect around 2.5% of that for supervision of the project to completion. You can agree with him on how the 2,5% will be played. you also need to give other allowances otherwise called reimbursable for accommodation, transportation, communication etc usually calculated as 1% of project cost. 220k is very fair.

why will some uninformed people Come up here to start saying rubbish because they need what to eat, see some educated folks saying architects are just for external or beautification which I will term aesthetics.
While it is not good to do the work of a structural man on site as an architect , the aspect of work of an engineer is restricted to the structurals only which are beams, slabs, columns and lintels n probably steel roof if it's to be used whereas an architects has a long n cordial relationship which extends to other aspect like plumbing, furniture, tiling, ceilings and so on because he is the one that designed all this things and as such understands better than anyone.
Engineers are very important in construction but architects comes way first before them. I as an Architect will never do the work of a structural engineer even though I know it very well but don't be surprised if I correct, suggest or even show a structural eng How things are done. So O. P, giving an architect the supervision is not a bad idea like this people are trying to make it seems. Peace

I have a brother who is an architect who won a contract sometimes ago but had consult a structural engineer to for professional advice when I'll comes to positioning of some columns and beams.

You can't pay his professional fees so just negotiate what u can afford

An architect does not need a structural engineer to position columns and beams unless if there is a discrepancy between architectural and structural drawings. Again an issue only an architect can resolve.

Well its only for naija you'll see these things happening... a structural engineer has his own specialty,a quantity surveyor too, and so does an architect... it doesn't matter if any of them can do the job of all( jack of all trades) just get someone who specializes in that field.

Architects neither design nor supervised foundations. But covil/structural engineers.

a foundation layout plan is produced by architects before engineers can produce structural drawings. the engineer's role is limited to checking reinforcements and concrete mix. While architect does the setting out, makes sure all walls are aligned as drawn in architectural drawings and gives the final foundation height above ground level. other aspects like fixing of plumbing waste pipes are better handled under the supervision of an architect not a structural engineer. an architect must be there to coordinate if the best outcome is required. please stop the misinformation. thanks.

@jonbosco89, to relieve u of all the plenty stress,let me recommend u to a reliable company that can help answer all your questions.

Did you know? A BOQ gives an estimated or anticipated contract sum. (very important to client). Don't build blindly, Get a BOQ and know what it'll cost you. Whatever is worth doing, is worth doing well.

You need a Civil Engineer to supervise your foundation not an Architect and make sure the engineer shows you how COREN certificate as well as previous projects handled. I personally feel the person is a quack to charge you below 500k.Good luck

Let me design (AutoCAD drawing) of the ME (Electrical / Mechanical drawing) for you in case it needed. You will tell me how you want it and will be perfectly drawn. Technicians/Electricians will work according to the plan. Please call 08062464354.

Thank you.

Beware of quack engineers parading themselves here. I'll rather you find a competent person not minding the price. Many will say I can do it, but at what cost?

I am an Architect based in Benin and I will advise you.

N220,000.-- is not too much for supervising a foundation. The breakdown will come.

Regarding who should supervise the foundation of a two storey building. You follow the necessary building procedures and regulations. You must first of all have the relevant things before commencing. In Edo state, You must have approved drawings that have been produced by the Architect and a structural engineer. Most 2 storey buildings are higher than 10m roof inclusive. Edo state new building laws state that any building higher than 10m needs a soil test carried out on the site prior. This is not only a building requirement, it is in your own interest.The load bearing capacity taken from different samples from the site carried out in the lab will inform on foundation type. Calculation sheets are not required like some other states.

The structural engineer cannot do any drawing until the Architect is done. The structural engineer prepares his working drawings based on the Architectural working drawings -where its already there stated that the foundation is to structural engineers specification-, and/but after all calculations and considerations, it should be clearly ascertained from the drawings where the columns should be placed, the depth and size of foundation and column bases will be shown. The type of reinforcement and number to be used for the columns which could be of different sizes likewise the bases.

With this information, the Architect that produced the drawings can supervise any competent professional building it for you. A qualified structural engineer or builder also can. But who else can set it out better than who produced the plan and site plan? He should follow what is approved. Though physically on site, one can make some adjustments, the best person to advise you on this is the person that did the design for you. Some other person can just come and say these Architects na mumu and take your kitchen to the junction, but the Architect has already written in the drawings that no one has a right to alter anything without his consent, and in his letter of undertaken which is now a requirement that he tendered to EDPA, he accepts liability only on the condition that he SUPERVISES the building.

For the charges, few can pay professional charges.
In small negotiate jobs like this, most qualified architects can charge a token of 100k for setting out such a building and 100k to 200k per stage.

-During setting out, the amount should cover those assisting him, materials like pegs, profiles, twines, nails and transporting them to site.
-The first stage should be throwing of lines, digging, casting, ironmongery and carpentry for bases and starter columns, forming and setting of blockwork to final DPC levels.
-The next stage should be filling, back filling and preparation for ground floor slab. This could include a ground beam, hardcore, BRC mesh, damp proof membrane, filling of blocks and ramming.

One should be careful, whether you use an Architect or anybody, Confirm the qualification and experience. There are so many people parading themselves as Architects and engineers, they will dig 300mm for you and do a foundation of 30mm. 2 storey territory should be atleast thrice as deep, 225mm foundation thickness for all walls and bases even thicker and Width as wide as what comes form the structural drawings. No cutting of corners, if the funds are not adequate or available for 16mm rods for instance and following the number designed (can be as much as six for some or all columns), hang on till you are ready.

Last but not the least, don't build without supervision.

Note; when you see almost 100 bags of cement are going for only the blinding, column bases and foundation alone, a concrete mixer could be desirable which provides a more fluid mix.

This is ironic, Why will architect give the final foundation height, is that an architectural element? Architect's concern is the building aesthetic and foundation, my friend, is not part of them. What if the location soil has low bearing capacity? One of the reason why this nation is not doing well is because we have professional who doesn't know their functions.

Height (above ground level) is whats on ARCHITECTS DRAWING. that's what he is referring to.
Depth is strictly to structural engineers drawing.

Thank you so much Mr Faridasr. This is exactly what I want to hear, for the fact I have zero idea of what the cost should be. I didn't come on this site to condemned the beautiful architectural works the guy has been doing but just to know what range of prices we should agree on. Not just for me but also for him. Everyone works to make profit and one needs not to spend excessively to get exactly what he wants. Unfortunately, this site is completely poising and turning the trust I had on the Architect. To the extent I almost gave the contract to someone who called himself a structural engineer. In a long run I discovered he has no qualification as an engineer. I engaged with him merely on conversations to know his method statement. He was telling me something strange in the building industry as well as condemning the work of the architect. I took his statement for verification, by well know structural engineer. I was advised he has no qualification as a structural engineer. I should give him distance. I am really please with your advice Faridasr. I think I have got exactly what I am looking for here. Thank you everyone for your contributions. For people like me be very careful who handles your projects "before you spend that money"

Is a site always flat as represented in architectural drawings? How many people bother to carry out topographical surveys before a drawing is produced. why bring up foundation depth when i didnt say the architect determines that. A soil analysis and load calculation determines depth of foundation. Are you saying an architect on site cannot measure depth of trenches without the presence of a structural engineer? My point still remains an architect is more relevant in all stages of a residential construction as long as the structural drawings were prepared by a competent engineer. If given a choice between an architect and engineer i will take the former.

Thank you so much Mr Megapro. The supervision charge I stated above is not for the brake down you mentioned. I have to pay for every token that is required for Material, pay for skill and unskilled laborer. The charges is for the architect to come to site take a look of what is going on if they are properly done. He will do the pegging (setting out) I will pay those that will assist him differently and he will collect his 80k for that. Every other thing, He will come to see if the digging is up to 3m or as it should be. He will supervise the footing, bricklayers work as well as concrete slab. On that he will collect 220K. That means altogether that will go into his pocket will be 300k. Hence, I am here for advice as I have zero idea about the issue completely.

b/w 80 to 100k is ok for the job.
don't go and waste your money paying so called "supervisor " when you need money to buy materials

Where is the location of the proposed project.

@Op abeg forget all these guys I ll advice u go with ur architect, some other guys will charge above that while some will charge lower than that. What you should look out for mostly is his competency and then his honesty, then you have the option of negotiating d fee he gave you.,am sure the said fee is negotiable. Then if he is not ready to accept what u can offer and u re not ready to pay his fee,You can then try some other competent hands.
And to the architects and engineers d op only requested for advice as per fee to pay, he already has someone that am sure designed d building, we all know d feeling when some other guys are trying to take over our clients..
