For the Timber Merchants in the house, do we have anyone who deals in Teak that is dry and milled to specifications? The most critical requirement is for the Timber to be dry and cut accurately straight. The size is 1.5" by 1.5" by any length greater than10'.

The location is Ibadan.

Thank you.

Hi all, does anyone know where I can get a Concrete Grinder/Scarifier/Shaver to rent or buy? I need something like the one in this attached photograph. It could be electric or Petrol driven, that doesn't matter.

Thanking you in advance.

People are really using the VRF/VRV these days. The reason why people run away from it is the initial cost but at the long run it saves cost on power. And majority are inverter system. Most of residential building in Ikoyi, banana island and some area in Lekki used the VRF/VRV system
Daikin
York
Panasonic
Midea
Etc

Thank you. This enlightens me more. I'll intensify my research then.

That is the edge you guys have over the rest of us. You move around and get better exposure.

I use water cooled chillers In my factory , for this my mall projects am using ducted split in some areas , I think that’s what it is called. Midea , imported myself . I think you can use vrf /vrv for all applications but I stuck with ducted for this my projects

This is one of the bigger VRF systems from Midea and it must be powering quite a few indoor units.

Where did you import from and how many indoor units do you power from this?

Was it easy getting these through the ports and did you have to travel abroad to purchase them yourself or did you order online?

I think you have a lot to share with us on this, if you don't mind.

FEGEITOK:
I got the best prices from these guys.

Better than any other person who sold the same brand.

I did my homework though.

got prices/vendors on a spreadsheet, so do your own due diligence.

I don't know if things have changed since then.

The multi-split system is so beautiful, I absolutely recommend it over individual split units especially if you are environmentally conscious or want to conserve power usage

Thank you for this information. I will pursue it accordingly.

On another note, how long does the AC run for with your Solar batteries and how many batteries do you rely on in powering the AC?

topsy23:
That's what we called multi split unit system. It almost similar to VRF system but the only difference between the multi split unit system and VRF system is that the maximum indoor you can install on multi split is 6numbers but vrf can take more .. they are both low power consumption equipment.

People are using it Nigeria

Daikin, York, Panasonic etc have those system

Spot on. If this is popular in Nigeria, how come the suppliers are not promoting them?

I have been struggling to find the information that you and our other folks on this forum have given in the past couple of days.

I hope we have folks who can also service them as well.

Thanks, this is amazing they are not multiple splits that as one single condenser outside unit with 4 to 8 split internal units. My concern about this particular unit is the cost of energy consumption. Although I understand it can be programmed to use any of the units when needed, but the condenser unit is running at capacity which I think is not cost efficient. Please, if you don’t mind can you share more lights on it, or if possible post what it looks like for others that may be interested to learn about it thanks. There is a debate between some professionals in that line, in regards to inverter AC’s and regular AC. Some are of the opinion that the regular AC’s is more powerful in times of output performance in cooling. The other opinion is the inverter AC’s are only good in energy savings but not strong in times of outputs of cooling.

In terms of effectiveness, the sizing has to be done before specs are agreed. The volume of the room and the direction of the dominant windows makes a lot of difference. Windows facing the sun in the late afternoons and evenings admit more heat and these should be considered when specifying the capacity.

Well, I am not the expert in this field, but the trick is that the condenser only runs at the optimal capacity based on the demand from the indoor units.

You are also able to have different rooms at different temperatures, as each room has its own thermostat and controls. Another advantage is that your entire house is served by a limited number of units, so you don't have condensers hanging all over the building. You can use different indoor units connected to the single condenser e.g. a wall-mounted unit and a standing unit and a ceiling-embedded unit and a concealed unit all powered by the same condenser.

A lot of these multi-splits also use the inverter technology as well as the newer R-32 refrigerant which are both good for the pocket and the environment.

I am sure some other clued-up folks in here will be better able to extend this list.

Hi, can you throw this open. What exactly do you mean halfway house between the fully central ones and individual split unit Ac’s ?

Multisplit or multi split ACs are systems that have 1 or more indoor units per 1 outdoor/external unit. This allows one to minimise the number of external ACs hanging out on walls.

They are not Central Air-conditioning Systems powering the entire house, but you can power between l and 6 units/rooms from just one Outdoor unit.

This allows you to purchase 2, 3 or 4 units to power the entire house.

They are much more energy efficient than the standard splits as they only generate output based on the demand for cooling. If you switch on the AC in one room, for example, it will only be using say 20% of the installed capacity.

We don't use it much in Nigeria because it is the next level up from split units and relatively newer in technology. I think it will become more popular with time and Solar deployments.

FEGEITOK:
I will share with you the number of the sales agent I worked with and the certified installer who installed mine.

That would be awesome. Thank you.

twinskenny:
We have GREE installed in this house… the inverter type both standing and wall split…. Low power consumption….

Powered by our installed 20kva inverter…

Note: we bought directly from their main distributor @ Apapa

Make it cheaper

Thanks Twinskenny.

I wasn't quite looking at Gree, but would appreciate your insight on this. I'll look up your number from your profile and get in touch.

Much appreciated.

FEGEITOK:
Try Daikin

They have exactly what you need.

And they have authorized dealers and certified installers in the country.

That was what someone told me a couple of days ago. I contacted EMC. I understand that they are Daikin's main supplier in Nigeria, but EMC hasn't responded to my WhatsApp enquiry though they have read the message.

I'll wait and see if they respond in the course of the next week.

Thank you.

desiji:
definetely the make is Gree i have two types one with 2 indoor and the other with 3 but i brought down from base (Germany) The are inverter Ac's without surge

Thank you desiji. The Midea units that I found were also from Germany and the trouble with importation and all is what is discouraging me from considering that option. I checked with Midea here in Nigeria and they either didn't understand, or they were too set in their ways to think of anything but the commonly available splits.

FEGEITOK:
A/C?

Yes, Air conditioning units. A halfway house between the fully central ones and individual split units

desiji:
Been using it since like 2yrs

That's gratifying. Are you able to share some details on make and supplier/installer either privately or through this public forum?

Thank you.

jabolo:
I am researching the multisplit options as I also abhor the clutter. Trouble is, the original building design ought to have considered it in the first place and hidden ducts can be provided for. It is difficult to retrofit into a completed building.

Having said that, we'll get there someday, so I would appreciate recommendations on the best vendors for multisplits in Nigeria.

Thanks in advance.

Any progress on this matter? I am looking too and would appreciate recommendations and/or referrals from this forum.

Thank you all

desiji:
Iam bringing mine done from Base i already did the consideration im my build so it was implemented in the building and so there was no visble pipes. 2ndly i found out that the cabling was different fro the one being sold in Nigeria thank God we already thought ahead. The one i am bringing down have WIFI which means you can program them when and how you want them to RUN and with the Solar software i am using you can use SONOFF gadgets tto do IOT however you want it

Just as a matter of interest, did you finally get this installed?

I have been looking at the Midea multisplit systems and have not found any suppliers in Africa. Where did you procure yours from?

If all of this is correct why is Yahaya Bello not approaching a court of law to resolve the issue?

Why resort to extra judicial resolution of an issue that is based on a contract?

It looks to me like our politicians only talk about the rule of law when it suits them so to do. This is a matter that is fully amenable to the rule of law and should be so resolved. The courts are also able to direct Dangote Group to pay the Kogi State government all of its accumulated dividends and back taxes.

Yahaya should head to the courts but leave the factory open and running.

Official: 2002 Agreement Between Kogi State Government and Dangote Industries Limited on Obajana Cement Plant

Extracts from the duly signed and stamped agreement:

1. Project was at conceptual stage in 1992

2. Preliminary feasibility study carried out in 1992

3. Obajana Cement Company Plc with Certificate of Incorporation No. RC208767 dated 4th November, 1992 is solely owned by Kogi state

4. Prospecting Right (Numbered PR No.14 of 2001 No.0053) was issued exclusively to the company

5. Kogi state offered and transferred 90% of its total shareholding in the company to Dangote Industries Limited

6. Kogi state is at liberty to sell half of its 10% equity to indigenes of the state by public offer or private placement

7. Kogi state shall grant Dangote Industries Limited tax waivers and exemption from levies for a period of 7 years from the date of commencement of production

Chasing automatic plate numbers may be good for the headlines, but what of the thousands of cars driving around the place unregistered and unknown?

How this could not attract the attention of a half-decent police force in a kidnapping and robbery-prevalent environment still beats my imagination.

The police should devote the required level of seriousness to wiping this out. It fuels crime more than anything else in our country today.

How much are these with the poles? Thanks

Are you skilled and experienced in multi-split air-conditioning systems, especially the Midea systems?

Good day folks, do we have any specialist and experienced HVAC personnel on this thread?

Please get in touch if you or anyone you know are skilled in multi-split air-conditioning systems design and installation.

Thank you.

To circle back. Ayinde started painting for me today using Gbadexy paint.

Thanks for the recommendation.

Please keep us posted on the quality of his work. The combination of @gbadexy and this Ayinde guy are on my shortlist as well.

Thanks

Ikmontana1:
please Boss, which COLOUR who you suggest I use that will last longer than BLACK ??

cause I plan to do the Roofing this month.

On a personal and functional note, I would suggest you go for any other colour that tickles your fancy so long as it is not Black.

Ibadan enjoys a humid tropical climate and Black absorbs heat. What this means is that your house will be extremely hot, unless you spend extra money to cool it via air-conditioning or through a design that dissipates heat within your roof, all the absorbed heat will end up in your rooms and will make your expensive building not very habitable or enjoyable.

Think twice on the colour and avoid the darkest colours.

The primary purpose of BRC wiremesh is adding strength to your oversite concrete. Been made of steel (Structural), we introduce it to oversite concrete to provide strength to the floor, therefore acting against crack.

Take for instance, A place with high movement traffic, or think about most heavy equipment we keep on the floor in our houses (Live loads), overtime fatigue might set in on the concrete, it is the function of the Wiremesh in the concrete to receive and help spread the load

See it this way, Wiremesh serves the same purpose steel bars serves in Reinforced concrete slab.

————————

To the best of my knowledge, the two main reason why German floor is done is to provide
Strength and Act against capillary Action

While Wiremesh along side Hardcore placement, Effective ramming acts for the former, DPM (Damprove membrane) acts for the later

I hope my answer is specific to your question
Good morning and happy new year once more.

Thank you, I get the specific context in which you are addressing this topic and you have done a good job.

The bit that got me worried was the placement of reinforcement in floor slabs.

What you were referring to in the thread is temperature and shrinkage reinforcement rather than structural reinforcement. Only shrinkage/temperature reinforcement requires top placement of the steel. And that would be because the lower part of the slab wouldn't be undergoing a massive amount of tensile stress, because it rests on the hardcore. We would have a massive structural failure and collapse if structural reinforcement is placed at the top section of a normal reinforced concrete slab,

I thought it was worth making this clear because we have a lot of people using this forum as their main Knowledge Base and lives depend on professionals doing the right thing.

Thank you for taking the time to break it down and happy New year to you and the forum family.

Charisdesigns:
First of all, Concrete cover is essential to create a bond between concrete and steel, it also help steel against corrosion and harsh weather. It is simply the clear space between the surface of concrete and the reinforcement steel.

In this context, concrete cover is the space between the ground and the BRC wiremesh.

Wiremesh should be placed at the upper third of the oversite concrete (German floor), This will help fight against shrinkage/crack which originate from the slab top.

While concrete provide compressive strength, the wiremesh provides tensile strength.

The attached is the section of the strip foundation I uploaded previously, the dark straight line under the part labeled “150mm concrete floor slab” indicates the BRC wiremesh and position.

Pics 2: How to achieve concrete cover. Notice the red bricks (biscuit) placed underneath the wiremesh


I hope I answered your question sir

@Charisdesigns

Please clarify the PRIMARY purpose of the BRC in the section. Is it as a binding agent for the concrete against cracks or it is structural?

Your clarification will help me resolve my confusion here.

Many thanks

Good evening everyone. I just want to confirm that I have been mobilized by somehow for the construction of window burglaries at his project site.


Work is supposed to start in two or three weeks time. I wish you join me on this journey and may credit alerts follow us this week

Congratulations! I'll be following and quietly cheering for you

michlins:
that picture is from the internet. Look at the head of the tiler

Well spotted, the environment looked sufficiently Nigerian to me that I neglected to zoom in any further.

Thanks

michlins:
this is the closest. This is the closest to what I can get which I know I can replicate. Costs 45,000/meter

The first sample is slightly close, but not with the gold stuff at all. Do you have a close-up picture of this?

Please guys I need your review on this proposed plan . My architect just presented it to me .

Two main areas that need further attention : I am guessing that your guests will, occasionally, need to clean up, but you don't seem to have provision for a bathroom.

The second point is in the width of your main entrance gate. You will need to widen it substantially for it to be able to accommodate a car in front of the property.
