Project Title: Residential Development Of a four bedroom bungalow

Project Location: Sabo-Gida, Edo state

Contractor : Harneyprojects ltd RC 781615 ( www.harneyprojects.com)

Client : Diasporan

Project cost: 23 million naira

The Construction team of 1 Coren registered engineer, Building technologist, carpenters, iron benders and other skilled artisans were dispatched to the site to execute the project located at Sabo-Gida, Edo state.
The team arrived late in the evening, work to commence the following morning

Due to the current cost of construction materials, its imperative for engineers, builders and architects to come together and look for solutions to drive down the cost of construction.
The most expensive and prevalent building material is cement, reducing the quality of cement in your structure can drive down the cost by 35%.
One of this solutions in reducing amount of cement in our structures is use of interlocking bricks which we would show later on in this thread

We start with the setting out


Setting out

The project commenced with the setting out operation to a transmit the site plan to the site.
The equipments used for the setting out are:-
- Building square
- Building working drawings
-Pegs
-profile board

The setting out operation took several hours but was completed once the last grid on the architural drawing was indicated on the profile board.

Excavation

Excavation of the prepared site began after the completion of the setting out. The soil was excavated to a depth of 600mm and a width of 675mm , this follows best practice for bungalow foundations. The width of 675mm would help to properly spread the load of the building.

Reinforcement works

We have 14 pillars in the architectural design of this structure, the pillars have varying dimensions. The iron bender started work on the reinforcement from day one in line with the work schedule. 4 nos of 12mm were used for the main bars while 10mm spaced at 300mm c/c was used for the shear reinforcement (rings).

Leveling Operation

Leveling operation was carried out with the aid of a dumpy level to a certain the differential levels of the foundation due to the topography of the soil.
An average strip footing thickness of 225mm was accertained which is in accordance for best practice for strip foundations used for bungalows.

Strip footing concrete works
Preceding the concreting was the placement of the reinforcement for the Architectural columns.
Concreting involved the placement of concrete in the excavated pit to serve as the strip footing with a dimension of 675mm x 150mm. This process is called "blinding by laymen".
The concrete was mixed properly and placed.

Foundation blockwork
After the conclusion of the Strip and pad foundation concrete work commonly called blinding, the next phase of work is the laying of the foundation blockwork by the masons.
A total of 4000 blocks were in 6 days. 9inch blocks were used for the foundation.
The blocks were laid to a height of 1.5m specified in the architectural design which is approximately 5 coaches of block.
The block holes were filled with weak concrete with a mix ration of 1:4:8

Grade Beam
A grade beam with a dimension of 225mm x 300mm was placed on the exterior blockworks due to the hieght of the foundation blockwork.
The grade beam involved capentry work, reinforcement works and concrete work.
4 Y12 was provided as the main bars while 8mm bars was placed as the distribution bars.

This concludes this stage of the project.
The filling and Dpc would follow next when work resumes in a few weeks time.
