Guidelines for site layout or job layout at construction site

Site layout refers to the plan of the construction site. It provides the area as well as the proper position for arranging the necessary resources in the construction work.

It specifies the place for offices, godowns, workshops, accommodation etc. It also illustrates the present relationship of the site with its surrounding with regards to communication, approaches and existing facilities.

Given below the importance of a systematic and technically organized site layout :-

1. Obtain an uninterrupted supply of materials in adequate amount.
2. Get a smooth access to material and test out its wastage and degradation.
3. Reduce the number of plants as well as the movement of heavy equipment.
4. Prevent confusion and minimize accidents.
5. Keep a systematic viewpoint for easy inspection of the materials.

The layout that fulfills most of these conditions enhances efficiency along with productivity. Such a layout is recognized as optimum layout. The site layout is mainly based on the following factors.

1. Position of the site, 2. Arrangement of space, 3. Access to the site, 4. Material volume, 5. Type of applicable equipment, 6. Ground conditions.

Fundamentals of jobs layout: The following fundamentals should be maintained for job layout.

1. If possible, there should be two openings in the site, one for entry and the other for exist to allow flow of traffic. For the existence of only one gate, then it is preferred to arrange a cross-over near the gate.

2. The general office should be situated adjacent to the main gate to stay away from confusion at construction site.

3. The godown should be situated just at the back of the general office so that the delivery of the material is accumulated in it. It also allows a tighter supervision of the stores.

4. Temporary roads should have been built up around the operation area. It makes the flow of material as well movement of equipment better. In reality, if such roads are essential to be built up in the project, it is suggested to build them initially in order that these can be utilized throughout the construction accurately.

5. The workshops for joiner, fitter, electrician etc should be determined and placed by balancing the easy and short access routes..

6. Staff accommodation should be far from noise. It should be centralized in one area to facilitate communication and trim down the cost of facilities and services.

7. The existing services should be used as far as possible.

Details of Foundation in Construction?

A foundation alias ground sill is the low part or sub-structure of an architectural structure that is artificially constructed on the soil to transmit loads from the structure to the ground securely. Foundation of a structure is built up underneath the ground level with the purpose of making the lateral strength of the structure better. The solid ground on which the foundation is supported is known as the Foundation Bed.

On the basis of the condition and bearing ability of soil and nomenclature of structure, the foundation is categorized as shallow foundation and deep foundation.

If the depth of the foundation is under or similar to its width or if the foundation is built up at proper shallow depth, it is called shallow foundation. A shallow foundation delivers the load to a stratum found in a shallow depth. Shallow foundations are generally found in building up low rise structures.

If the depth of the foundation surpasses its width or if the foundation is developed at considerably large depth, it is call deep foundation. The deep foundation transmits the load to a wider depth under the ground surface. Deep foundation is intended for high rise or multi-storey structures.

1) Shallow Foundations
i. Spread footing or open trench foundations
ii. Grillage foundations
iii. Mat or Raft foundations
iv. Stepped foundations
v. Inverted arch foundations
vi. a) Wall Footing
vii. b) Reinforced cement concrete footing
viii. c) Combined footing
ix. d) Eccentrically loaded footing

Deep Foundations - i. Pile foundations, ii. Well foundations, iii. Caisson foundations

To erect a foundation, trenches are excavated thicker into the soil unless a solid stratum is attained. To make the base foundation, concrete is poured into this trench. These trenches are combined with reinforcement cage to raise the foundation stability.

The estimated steel rods which are provided outwards perform as the bones and should be attached with the substructure above. Once the foundation work is completed successfully, the structure of the building is started.

The construction of the foundation can be done with concrete, steel, stones, bricks etc. The material and the type of foundation selected for the desired structure depends on the design loads and the type of underlying soil.

The design of the foundation must incorporate different effects of construction on the environment. For example, the digging and piling works done for deep foundation may result in adverse disturbance to the nearby soil and structural foundation. These can sometimes cause the settlement issues of the nearby structure. The objective of developing of a foundation is to withstand the attack of injurious substances from outside.

The foundation for each structure is made by adhering to the following guidelines:-

1. The underlying soil beneath the foundation structure does not experience shear failure
2. The settlement should be occurred throughout the first service load or should have been within the limit
3. Acceptable bearing pressure should be described as the pressure the soil can resist devoid of any failure.

Objects of Foundation:

1. To allocate the load of structure on wider area to maintain the intensity of load under the safe bearing capacity of the underlying soil.
2. To allocate the load uniformly on the underlying soil to avoid any unequal settlement of foundation.
3. To arrange leveled and hard surface for the super-structure to be constructed over it.
4. To raise the strength of the structure completely against sliding, overturning or other distressing forces like wind, rain, earthquake etc.

Brief overview of workability of concrete

The strength & longevity as well as the cost of labor and look of the finished product is greatly impacted by the workability of concrete. The concrete can provide better functionality, if it is easily positioned and compacted consistently devoid of bleeding or Segregation.

The concrete that is not in good working condition should be supported with extra work and endeavor for being compacted in position, also honeycombs &/or pockets are also found in finished concrete.

Definition of Workability: Concrete workability defines how smoothly freshly mixed concrete is amalgamated, arranged, compacted and finished by keeping the conformity as it is. Workability refers to a property that directly affects strength, quality, appearance, as well as the cost of labor for placement and finishing operations.

The workability is impacted with the following factors :

1. Water content in the concrete mix
2. Amount of cement & its Properties
3. Aggregate Grading (Size Distribution)
4. Nature of Aggregate Particles (Shape, Surface Texture, Porosity etc.)
5. Temperature of the concrete mix
6. Humidity of the environment
7. Mode of compaction
8. Method of placement of concrete
9. Method of transmission of concrete

The workability of concrete can be improved in following ways :-

1. Raise the proportion of water/cement
2. Raise size of aggregate
3. Apply well-rounded and smooth aggregate rather than asymmetrical shape
4. Rise the mixing time
5. Enhance the mixing temperature
6. Employ non-porous and saturated aggregate
7. Include air-entraining mixtures

The most recognized method for measuring the workability of concrete is Slump Test.

Some useful tips for making inspection of reinforcement in jobsite

Though the inspection of reinforcement involves lots of complexities and huge cost, but the problem should be properly resolved by appointing a standard consulting firm for accomplishing the inspection work.

The first step should be checking drawing. One must have adequate knowledge for analyzing a rebar drawing. The field engineers should have proper knowledge & capability to communicate with it in the jobsite.

To become an efficient rebar checker, practice for reading drawings on a regular basis. For this purpose one should gather proper knowledge with the steel rebar binding process. Given below, some useful tricks provided by some top peers who have lots of experience in this field :-

It is suggested to carry a measuring tape with yourself all the times for the purpose of examining the spacing and the splice or development length.

One should have clear conception on physical features of the construction component i.e. if some type of drainage pipe or electrical conduit should be set up or water stopper should be substituted or any other pipes / implanted item should be arranged.

Initially, the diameter of rebar should be examined properly through a vernier caliper. The other important things which should be examined thoroughly are rebar spacing, rebar development length, lap / splice length, alignment, no sag or buckling present in the bars, the couplers should be perfectly set and tightened, bars should be perfectly fixed, there should not be any rust on the bars, check for proper clear cover, no of bars should be computed properly and be similar with the drawings and should not be under or over 2 bars which are arranged there.

Always take suggestions from the contractor’s foreman or site engineer for the placement of the bars.

One should have sound knowledge with the steel quality tests like tensile strength check or torsion failure strength or coupler tension strength check etc. Make sure that the applied steel is taken from the verified lot and must not be a failed quality.

Though proper execution of design becomes very complicated because of inconsiderate field conditions and difficultly in installation / fixing of rebars, but always ensure the design of reinforcement is completely perfect as improper design can lead to failure of a building if fully neglected / violated.

Always keep in mind that the orientation of bars like main rebars should be under the distribution or temperature rebars. It can be verified from the drawings delivered to you.
