Construction

We are determined to provide quality housing through construction of modernized houses

Our management approach is to improve efficiency, performance and reduce construction wastes. The new classical Architecture promotes a sustainable approach towards construction that promotes and develops smart growth, architectural tradition and classical design.

Incase of bad weather, the construction site may be shut down until favourable climate

During this time scaffolded tents may be erected in the site thereby reducing the number of lost days

We offer the following types of construction



Construction of residential and commercial buildings

Residential

The most common type of construction for residential purposes are maisonette and bungalow

We have an experienced team that has build hundreds of them

The following are the typical initial construction steps for a single-family or small multi-family houses

  • Development of floor plans. Materials list for estimation are obtained.
  • Building approval is obtained from the government
  • The building site is cleared
  • Survey is done to stake out for the foundation
  • The foundation is escavated and footers are dug
  • Foundation and footers are poured with concrete
  • The construction process is now underway till is done

Non-residential(Commercial)

We develop commercial buildings such as flats through modern design technics

Here are some of our works

Construction process

The design is translated into reality

The design oftenly consists of drawings and specifications usually designed by the design team including architech, civil engineers, mechanical engineers, electrical engineers, structural engineers, fire protection engineers and planning consultants.

Formwork Technology


aluminium formwork

Formwork is a temporary structure used to shape and support the concrete until it attains sufficient strength to carry its own weight. It should be capable of carrying all imposed dead and live loads apart from its own weight.

Variety of materials are used such as steel, timber, plastics and fiberglass.

A good formwork has to achieve a balance of the following requirements inorder to carry out its functions:

  • Containment - It should be able to shape and support the fluid concrete until it cures.
  • Strength - A good formwork should be capable of safely withstanding without distortion.It should not danger the dead weight of the fluid concrete, labour weight, equipment weight and any environmental loadings that is placed on it.
  • Resistance To Leakage - All joints in form work must be either close fitting or covered with form tape to make them grout tight. If grout leakage occurs the concrete Will leak at that point. Leakages cause honeycombing of the surface.
  • Accuracy - Formwork should be accurately set out so that the resulting concrete product is in a right place and is of correct shape and dimensions.
  • Ease Of Handling - Form panels and units must be designed so that their maximum size does not exceed that which can be easily handled by hand or mechanical means. In addition all formwork must also be designed and constructed to include facilities for adjustments, leveling, easing and striking without damage to the form work or concrete.
  • Finish And Reuse Potential - Form face material must be selected to be capable of consistently imparting the desired concrete finish (smooth, textured, featured or exposed aggregate etc.) and also achieve the required number of reuse.
  • Access For Concerted - Formwork arrangement must be provided access for placing of the concrete. The extent of this provision will be dependent on the ease of carrying out the concrete operations.
  • Economy - Formwork is very expensive. On total average about 35% of the total cost of any finished concrete unit or element can be attributed to its formwork; of this just over 40% can be taken for material for formwork and 60% for labour. Therefore, the formwork designer must not only consider the maximum number of times that any form can be reused, but also produce a design that will minimize the time taken for erection and striking.

Construction of formwork

  • Propping and centering - The props used for centering are steel, timber post or ballies. Pillars made up of brick masonry in mud mortar are sometimes used as props.
  • Shuttering - It is made up of timber planks or may be in the form of panel unit made either by fixing ply wood to timber frames or by welding steel plates to angle framing.
  • Provision of camber - There are certain amount of deflection in the structure which is unavoidable. It is therefore desirable to give an upward camber in the horizontal member of concrete. structure to counteract the effect of deflection
  • Cleaning and surface treatment - Before concrete is layed, The formwork is cleaned of all rubbish particularly the sawdust savings and chippings.
    The face of formwork in contact with concrete is cleaned and treated with release agent like raw linseed oil or soft soap solution to prevent the concrete getting struck to the formwork.

Removal of formwork

Walls, columns and vertical sides of beam 2 days
Slabs 3 days
Beam soffit 7 days
Removal of props and slabs.Slab spanning upto 4.5M 7 days
Slab spanning over 4.5M 14 days
Removal of props and beams and arches spanning up to 6M 14 days
Spanning over 6M 21s days

Bridge construction

We build different types of bridges. The bridges are classified by how the forces of compression, tension, bending, torsion and shear are distributed through their structure.

  • Structure type:
    1. Beam bridge
    2. They are horizontal beams supported at each end by a substructure units which can be simply supported when the beams only connected across a single span or continuous when they are connected across two or more spans. In case of a multiple span, the intermediate supports are known as piers.

    3. Truss bridge
    4. Truss is a structure of connected elements forming triangular units. This is a bridge whose bearing substructure is composed of truss. The connected elements which are typically straight may be stressed from tension, compression, or sometimes both in response to dynamic loads.

    5. Cantilever bridge
    6. Cantilever are horizontal beams supported on one end. Cantilever bridges mainly use a pair of continuous spans which extends from opposite sides of the supporting piers to meet the center of the obstacle the bridge crosses. They are constructed using much the same materials and techniques as the beam bridges and the difference comes in the action of the forces through the bridge.

    7. Arch bridge
    8. These type of bridges have abutments at each end. The weight of the bridge is thrust into the abutments at either side

    9. Tied arch bridge (bowstring arches)
    10. These bridges have arch-shaped substructure and the ends of the arches are restrained by tension in the bottom chord of the structure.

    11. Suspension bridge
    12. These types of bridges are suspended from cables that hang from towers that are attached to caissons or cofferdams. The caissons or cofferdams are implanted deep into the bed of the river, lake or ocean. Subtypes include:

      • Simple suspension bridge
      • Stressed ribbon bridge
      • Under spanned suspension bridge
      • Suspended-deck suspension bridge
      • Self anchored suspension bridge
    13. Cable-stayed bridge
    14. They are held by cables like the suspension bridge but less cable is required and the towers holding the towers are proportionally higher.

Landscaping

Landscaping is an activity that modifies the visible features of an area of land. These activities include:

  • The natural elements such as landforms, terrain shape and elevation, or bodies of water
  • Abstract elements such as the weather and lighting conditions.
  • The living elements such as flora and fauna; commonly known as gardening, the art and craft of growing plants with a goal of creating a beautiful environment within the landscape.

Landscaping varies according to different regions and therefore detailed study and observation is carried out by the team of experts before any commencement of work

We ensure we have fully understood the site by considering the following factors:

  • Different natural features like terrain, topography and soil qualities
  • Prevailing wind
  • Depth of the frost line
  • System of native flora and fauna

Sometimes grading (such as removal of excessive waste (landfills), soil and rocks) is done in order to landscape it.

Working procedure

A team of landscaping contractors creates a letter which is a rough design and layout of what can be done with the land in order to achieve the desired outcome

3D graphics of the pictures and plans are made

Legal frameworks are carried out
