@mufutau55, email addy is seyisodiya@yahoo.co.uk

@fastshipping, thanks for the compliments, we try our possible best to deliver strong structures to our clients.

All works on the second floor platform concluded today with the completion of the labourers stairs.

Clearing of the site for delivery of granite and sharp sand now in progress, by Gods grace, we should be able to cast on Friday or Saturday.

@Jamesqu, I actually don't cost an arm and a leg, my fee is quite reasonable and is based on a percentage of the estimated total cost of construction.

The location is off Ogunlana drive in Surulere and the pile foundation was recommended from the soil test done for the approval process.

Welcome onboard guys, am sure its going to be an educative and rewarding time for us all.

The project will be executed in two phases, phase 1 will be the construction of 2 units of the terrace to completion and phase 2 will have the other 2 units completed. This is due to the projected and anticipated cashflow of the client and to forestall hanging the project in limbo, it is wiser to carry it out in 2 phases.

@twinskenny, thanks for the props.

Electrical conduit work ongoing and plumbing conduiting also.

The iron bender is done with the floor slab reinforcement and has started work on the staircase reinforcement and hopefully should be done by Monday evening so the carpenter can wrap-up work on the stair risers also.

By Gods grace, we will cast the second floor suspended slab within this week.

BITSWORKS Nigeria is a multi-discipline construction company comprising of architects, builders, civil engineers and interior designers.

We will share the floor plan,elevations and 3D views once permission has been given by the client.

Size of land - 648.00 sqm
Total area of building - 161.46 sqm
Total unbuilt area - 486.54 sqm
Percentage of site covered. - 37.9%
Percentage unbuilt - 62.1%

Estimated budget for construction - N40million
PROJECT timeline - 6 months

Mobilization to site and site clearing/grubbing started on Saturday 6th of June 2015, here are some pictures taken on site. Strip foundation will be used due to the firmness of the soil. Settting-out and foundation excavation will start next week.

The client has made arrangement with a block industry to make blocks on site and that will start next week also.

Iron reinforcement work in progress, top bar and return bar work in progress.

Staircase wood formwork in progress, 1st and end unit formwork done, working on the 3rd unit.

Wood formwork and iron reinforcement work in progress. We got a bit delayed by the rain drizzling but got back on the platform once it fizzled out.

Wood formwork done except for the staircase, reinforcement work starting to take shape. Its looking like we will do the suspended slab casting atleast a week earlier than projected.

Wood formwork in full gear, the platform should be ready by tomorrow, Saturday and the iron reinforcement work can commence on it.

Staircase formwork will start on Monday and hopefully should be done by Wednesday.

We decided to use marine board for this suspended slab to hasten the process of formwork and also do a neater job while we can also still reuse the boards for our next project.

I will be looking forward to your mail @Jazes.

Formwork for the 2nd floor suspended slab started yesterday and so far, work is going on at a good pace. All the beam side boards are in place and the 2x3 wood runners have been fixed for the first terrace unit with the bamboo bracing in place also.

Iron reinforcement work for the beams will start tomorrow.

Sorry for the slow pace of project update and pictures, we also have new projects in the pipeline that has been taking more of our free time.

We are done with the columns and lintels and are getting ready for the second floor suspended slab. We will be using marine board (8ft x 4ft) for the formwork floor and 1x12 plank for the side board and others.

Its a viable business and can be operated by a lady. Am thinking of starting something small too in this direction.

Columns and lintels work on the first floor blockwork started on Wednesday and was concluded today.

One more coach of blockwork and we will start the formwork for the second floor suspended slab.

Blockwork started today, a week after casting. We will leave the bamboo decking support in place for a minimum of 3 weeks (21 days) for the concrete slab to cure and gain strength.

Blockwork should hopefully take us between 4-5 days and we can start the formwork for colums and lintels.

Thanks for the compliments all, much appreciated. Our aim to provide the most basic step by step processes for erecting a structure.

My email is seyisodiya@gmail.com, will be looking forward to your mail @seuner.

More casting pictures of the first floor suspended slab.

We casted the first floor suspended slab on Friday May 1st 2015 as scheduled.

The casting crew comprised of a team of 32 people mostly made of headpan carrying aboki's.

We used a total of 251 bags of Dangote cement (42.5 grade), 3 trips of 20 tons sharp sand (ogun) and 4 trips of 15 tons granite (3/4 down).

Mix ratio used was 1:3:4.

Casting started a bit late by 10am but we were able to finish up quite late in the night.

More reinforcement and wood formwork pictures. We are aiming to do the casting by Friday.

@Youngbrain Yes it is, thanks for the remark.

Formwork and reinforcement work for the first floor suspended slab has commenced and we are looking at casting before the end ofthe month.

Serious buyer, N1.500 and I will pay tomorrow morning. Pls call or sms 0807255501.

Columns and lintels have been casted, work has been a bit hectic hence the reason I haven't updated the thread in a while.

Marine board for the lintel and columns formwork was delivered to site on Tuesday 31st of March and formwork started on Wednesday.

A total of 36nos of 8ft X 4ft board was purchased and splitted to 12inches, 6inches and 8inches.

@tsiriman, no. We have treated the exposed part with damp proof course before casting the german floor.

Blockwork has been done to lintel level for the 3 units and 11 course where there are no windows or door.

Work is moving on at a steady pace today and its all beginning to make sense to the project owners, before it seems to them they were burying money under the ground.

Full blockwork started on Tuesday morning and by the end of the day, much had been achieved. We are working with a team of 4 highly experienced bricklayers and 2 labours.

Block work started on Monday 23rd of March, blocks were delivered late to site and not much was achieved that day but we were able to do the floor layout design.

We will be using 9inch block all through the structure except for the demarcation walls between units where we will be using dual 6inch blocks to create privacy and a sound barrier.

We used a total of 178 bags of cement( budget was 180 bags), 3 trips of 15 ton granite and 2 trips of 20 ton sharp sand(Ogun sharp sand).

We actually had some leftover of sharp sand from the ground beam casting so we used this as supplement for the 2 trips bought. Its important not to buy excess material which might not be useful for subsequent phase of the project.

The total iron used for the reinforcement was 3 tons of 12mm Tiger TMT.

The casting took a total of 8 hours plus and the team put the mixing machine on the ground beam reinforcement and pour directly on it. Once they are done with a sector, they shifted the mixer backward.

3 people had the task of spreading it out and after it is vibrated, the man with the wooden trough leveled it evenly and took levels with a plumb at intervals for accuracy( I actually insisted on them using a plumb because they claimed it was not neccesary).

The casting team used a total of 14 people, 1 man handling the machine, 1 water handler, and the rest distributed across sand, granite and cement carry and spreaders. They actually only do concrete work and are quite efficient.

Casting of the german floor was done yesterday 18th of March. The casting team contracted got to the site at about 8am and started casting at 10am after having breakfast and checking their mixing machine.

Bags of cement were brought out from the storage room and the ratio mix we are using is 1:2:3 meaning we will be using 1 bag of cement, 4 headpans of sand and 6 headpans of granite. This is a very strong mix ratio that is cement consuming but we aim at quality for our client and don't take short cuts when it comes to construction.

Reinforcement laying commenced on Friday 13th of March and was concluded by Sunday 15th of March. 12mm iron reinforcement of Tiger TMT brand was used and 200mm spacing was used between bars.

Conduit pipe laying for electrical and plumbing was also done.
