6 Kinds of Construction Backfill Materials And Their Use

In case of civil engineering, it is important to understand the use of various materials along with their properties such as construction backfill material. For that, a civil engineering training center would be of great help. You can benefit from the courses offered by them.

In this article, we will be seeing the use and properties of construction backfill materials used during construction. Of course, it would be an introduction kind of a thing.

Different sorts of backfill materials are utilized as a part of the construction industry. Construction backfill materials that are generally utilized are described underneath with their engineering properties.

  1. Rocks:

The appropriateness of rock as backfill material is very needy upon the degree and hardness of the rock particles. The amount of hard rock uncovered at most subsurface structure locales is generally small, yet select cohesionless materials might be hard to discover or might be costly. In this way, excavated hard rock might be indicated for crusher processing and utilized as select cohesionless material.

  1. Commercially produced By-Products:

The utilization of commercial by-products, e.g. furnace slag or fly ash remains as backfill material, might be favorable where such products are locally accessible and where appropriate natural materials can’t be found. Fly ash has been utilized as a lightweight backfill behind a 25-foot-high wall and as an added substance to very plastic clay. The appropriateness of these materials will rely on the attractive attributes of the backfill and the engineering qualities of the products.

  1. Coarse grained soils:

Coarse-grained soils are made up of sandy and gravelly constituents and range from clayey sands (SC) through the properly graded gravels of gravel-sand blends (GW) with practically no fines. They will display slight to no plasticity. The majority of the all around graded soils falling in this classification have genuinely great compaction qualities and when sufficiently compacted give great backfill and foundation support.

For sands and gravelly sands with practically zero fines, great compaction can be accomplished in either the air dried or soaked condition. Downward drainage is required to keep up seepage forces in a descending way if saturation is utilized to help in compaction.

Thought might be given to the economy of adding concrete to settle sodden clean sands that are especially hard to compact in narrow restricted areas. Be that as it may, the addition of concrete may create zones with more prominent rigidity than untreated adjacent backfill and form “hard spots” bringing about non-uniform stresses and distortions in the structure.

  1. Marginal materials:

Marginal materials are those ones that because of their lesser compaction, swelling or binding attributes would not regularly be utilized as construction backfill materials if sources of suitable materials were accessible. Material considered to be marginal incorporate fine-grained soils of high plasticity and expansive clays. The choice to utilize marginal materials ought to be founded on economic and energy preservation contemplations to incorporate the cost of acquiring reasonable material whether from a remote borrow area or commercial channels, conceivable trouble repair costs caused by utilization of marginal material, and the additional costs required in handling, placing, and sufficiently compacting marginal material.

  1. Shale:

Despite the fact that shale is normally referred to as a rock, the property of a few shales to break down under substantial compaction gear and slake when exposed to air or water after placement warrants special consideration.

  1. Finely grained soils of low to medium level plasticity:

In case of organic clays (CL) of low to medium range plasticity (sandy, gravelly or silty clays and lean clays) and inorganic residues and fine sands (ML) of low plasticity (silty or clayey fine sands and clayey silts) are incorporated into this class. The inorganic clays are moderately impenetrable and can be compacted reasonably effortlessly with substantial compaction equipment to give a decent stable backfill.

Soils under the CL group can be compacted inbound areas to a genuinely high level of compaction with legitimate water content and lift thickness control. The clayey sands belonging to the SC group and clayey portions of the ML category can be compacted to genuinely high densities, however close control of water content is basic and at times basic, especially on the wet side of ideal water content. Some ML soils, if compacted on the dry side of ideal, may lose significant quality upon immersion after compaction. Considerable settlements may happen.

Caution should hence be practiced in the utilization of such soils as backfill, especially underneath the ground water level. Likewise, saturated ML soils are probably going to be profoundly powerless to liquefaction when dynamically stacked. Where such soils are utilized as a refill in seismic prone areas, lab tests ought to be conducted to decide their liquefaction potential.

That was regarding the construction backfill materials used during construction work.

These days, many courses are specially designed for training civil engineering students. You can benefit from them.

Engineer’s Guidelines For Building Bridges

Engineers are regularly associated with bridge construction and rightly so. Building bridges is something beyond laying heap of woods over an impediment. It is a structure that should keep going strong for quite a while and it ought to viably serve its need. To accomplish this, engineers need to carefully and fastidiously design a bridge.

Engineer's Guidelines For Building Bridges

Interested in doing such kind of work? Then, civil engineering is the right profession for you and civil construction training courses would help you big time.

While there are distinctive sorts of bridges and the design and plan may contrast, the general rules while building a bridge continue to remain as before.

Guidelines For Engineer while Building Bridges:

  1. Environmental factor:

A bridge can be a structure constructed over different kinds of obstacles which may incorporate rivers, valleys, gorge, trenches and others. The environment on which the bridge will be developed ought to never be overlooked in the equation. A few bridges failed in light of the fact that designing the blueprint was profoundly focused on the bridge itself, while disregarding outside factors that can influence the life expectancy of the bridge. For instance, a bridge worked over a river should ensure that the foundation is legitimately established. Water scouring may consume the soil from the base and damage the bridge right from its foundation.

  1. Function:

A bridge can take different structures and serve diverse purposes. A bridge specially built for individuals will be not quite the same as a bridge constructed for large vehicles. On the off chance that the primary function of a bridge is to transport individuals, at that point the bridge can be constructed with lighter materials. In any case, if the bridge is going to be utilised by vehicles, at that point planning ought to incorporate high quality materials also.

  1. Materials:

There are a considerable measure of materials that an engineer can pick from. These may incorporate steel, wood, plastic, cement and others. With the developing concern for sparing the earth, a few bridges are presently imaginatively intended to be more Eco-friendly. This implies a few bridges are currently built using reused materials.

  1. Costing:

Possibly the number 1 deciding element that influences bridge construction is the budgetary aspect. The design, materials and work force are specifically reliant on the apportioned budget. It will be in vain to plan building a bridge and just to discover that there is no enough cash to complete the project. Keep in mind that bridges will take months and years to construct and it will absolutely require a major measure of cash to manage its construction until the very end.

  1. Weight:

An intelligent engineer would consider the weight that will go through the bridge. While it is basic to think about the vehicles going through the bridge, the heaviness of the materials ought to be contemplated too. Without legitimate count and right planning, a bridge can fall a long time before it is being built.

  1. Architectural design:

A bridge ought not simply be functional, but rather it ought to likewise be tastefully designed. Obviously, this is not of most extreme significance, in any case, a bridge built with beauty and in an impressive manner is a certain construction reward.

These are just a portion of the factors and guides that each engineer ought to recall. Keep in mind that the effectiveness of a bridge will significantly rely on the designing and planning of engineers.

Keep these guidelines in mind before you go ahead with the construction of a bridge.

Hydro-Power and It’s Role In The Future

Here, we are going to see about hydro-power and the role it has to play in the near future. It holds importance from the civil engineer‘s perspective, and it is therefore essential to understand.

For those who want to work in this sector, a civil engineering training program would serve to be of great help. Seriously think of joining one.

Hydro-power does not release pollutants into the surroundings; be that as it may, it is not free from hazardous ecological impacts. Extensive endeavours have been made to decrease ecological issues related with hydro-power operations.

Efforts to guarantee the safety of dams and the utilisation of recently accessible computer technologies to enhance operations have given extra chances to enhance the environment. However, numerous unanswered queries stay about how best to keep up the monetary feasibility of hydro-power even with expanded demands to secure fish and other natural resources.

     Hydro-power:

  • Safety of dam

  • Hydrology

  • Passage of fish, behaviour and response

  • Water resources management

  • Turbine-related projects

  • Maintenance and operations

  • Quality of water

  • Inspecting tool development

Today, engineers need to take advantage of newer and current facilities to expand generation and proficiency. Existing hydro-power ideas and methodologies include:

  • Pumped storage

  • Uprating the current power plants

  • Rising with hydro-power

  • Associating hydro-power to various forms of energy

  • Coming up with small plants (low-head hydro-power)

If you are a starter in this field, you can go for courses for beginners. They would help you gain the required knowledge at this level.

Low-head hydro-power:

A dam with low-head is unified with a water drop of under 65 feet and a producing capacity under 15,000 kW. Huge, high-head dams can create more power at bringing down expenses than low-head dams, however, construction of huge dams might be restricted by absence of suitable locales, from environmental perspective, or by financial conditions. Interestingly, there are many existing little dams and drops in height alongside canals where little generating plants could be introduced. Newer low-head dams could be built to expand output too. The key to the usefulness of such units is their capacity to generate power close where it is required, diminishing the power definitely lost amid transmission.

Uprating:

The uprating of existing hydroelectric generators and turbine units in power plants is a standout amongst the most quick, financially feasible, and ecologically adequate methods for building up extra electric power.

Peaking with hydro-power:

Requirements for power shift greatly amid the day and night. These needs differ greatly from season to season, too. For instance, the most noteworthy pinnacles are generally found amid summer daylight hours when Ac’s and cooling systems are running. Atomic and fossil fuel plants are not proficient for creating power for the brief times of expanded demands amid peak periods. Their operational prerequisites and their long startup times make them more productive for addressing base load requirements.

Since hydroelectric generators can be begun or ceased in a flash, hydro-power is more responsive than most other energy sources for taking care of peak demands. Water can be stored away overnight in a reservoir until required amid the day, and after that discharged through turbines to produce power to help supply the peak load requirements. This blending of power sources offers a utility company the adaptability to operate steam plants most effectively as base plants while addressing crest needs with the assistance of hydro-power. This procedure can help guarantee solid supplies and may help dispense with brownouts and power outages caused by incomplete or total power failures.

High-Performance Concrete: An Informative Guide

High-performance concrete: 

As a part of our civil engineering blog, today we are going to share information about high-performance concrete. Civil engineering is a growing sector in our country. It would assure a promising career for the aspirants. The need is to undergo civil training courses and become skilled civil engineers.

High-performance cement gives the high level of strength, durability, quality, low water concrete proportion and longer life expectancy of the structure. Exceptional fixings, e.g. plasticizers, ideal aggregate size, and fiber steel fortification are utilized to make this kind of a concrete admixture. This kind of concrete type is utilized as a part of exceptional and complex development structure, e.g. tunnels and bridges. High-performance cement likewise helps in diminishing the term of the venture, as there is low water concrete proportion in making the admixture for the cement. This kind of concrete is helpful for fast track constructions where proprietor required the ownership of the property at the earliest opportunity. High-performance cement has a few advantages over customary Portland cement concrete.

Special admixture such as fly ash and silica fumes can be utilized to supplant the mineral admixtures to increase the workability and strength of the concrete so as to create high-performance concrete. High rate utilization of fly ash builds the set time of concrete and moderate advancement of strength. This setting time of concrete admixture can be lessened by including the plasticizers in the admixture. Plasticizers likewise quicken the strength picking up the procedure of the blend. Be that as it may, presentation of plasticizers builds the cost of cement essentially. Then again, by supplanting cement 100% to fly ash based hydraulic binder produces green concrete (zero carbon outflow). Green cement made of fly ash-hydraulic binder can quicken the mechanical and also customary properties of concrete. Green concrete provides higher workability and strength than customary conventional Portland cement concrete.

Fly ash can be utilized as extraordinary fixing to make solid blend green and increment the strength and mechanical properties of the concrete.

These constituents are friendly from the environment perspective and aides in creating sustaining construction. Besides, mineral admixtures are by and large industrial wastes or by-products, disposing of these industrial by-product materials could lead to an economic loss and an issue as for environmental and health related problems.

Industrial training for civil engineering students can prove to be useful and help them to gain knowledge about all these things related to the civil branch.

For now, let’s continue with our topic…

The strength factor achieved by high-performance concrete in starting setting time is more than Portland cement concrete. The superplasticizers present in the concrete admixture lessens the water content and increases the strength at the beginning setting time. High-performance concrete is a pivotal swap for Portland cement concrete for big development sites, like, bridges, tunnels, and highways. The solidness of the high-performance concrete is longer than Portland concrete. High-performance concrete gives longer life expectancy to columns, girders, and slabs. The dry shrinkage of this type of concrete is lower than Portland cement concrete since fly ash fills the gaps between coarse material and cement particles. High-performance concrete is otherwise called green cement. The volume of CO2 radiated by HPC is lower than Portland cement concrete. It can be utilized to make maintainable admixture. Thus, high-performance concrete is a superior substitution over customary Portland cement concrete.

Traditional Portland cement concrete constitutes coarse materials and sand, which does not fill the voids amongst cement and the aggregates. These void outcomes in dry shrinkage of concrete when the water cement proportion in admixture is lessened with plasticizers to make it high on performance. Dry shrinkage of concrete prompts breaking and failure at the starting settlement duration. Quartz and silica fumes are exceptionally chemical resistant, which makes them supportable and lessens the amount of CO2 emission.

Thus we saw a few things about high-performance concrete.

Engineers: The Present and The Future !

In this article, we will be focusing our attention on the present and future of engineers. In fact, why they are important today and tomorrow.

Engineers, that includes civil engineers are in great demand. To grab the number of opportunities by gaining the desired skills, you can opt for a training program for civil engineering.

Now,

Let’s discuss about the present and future times for engineers.

Today’s cutting edge world is made up of machines and gadgets. We’re encompassed by products and vehicles alike – telephones, PCs, tablets, automobiles, scanners, drones, switches, 3-D printers – all of which have been precisely designed and effectively manufactured. Each one of these bits of hardware is a guileful assembly of structure, circuits, material, data, and bundling. Who unites it all and transforms a heap of crude materials into something useful? It’s the job of the specialists i.e. engineers. Engineers are in charge of topping off the universe of things we live in. Each gadget we use, from a TV remote to an aircraft, is designed by engineers.

Engineering is a one of a kind career. It requires its own kind of insight which is different from that utilized in numerous other fields. Students who qualify in government, economics, communications, and different territories of study don’t utilize a similar mix of thought that expert engineers require. To be a decent engineer, you have to acquire a portion of the craftsman’s creativity and the accountant’s urge for details. You have to comprehend maths and programming completely. You require confidence and the capacity to motivate yourself. Engineering connects with both the left and right sides of your cerebrum always. A few people simply don’t have the wonderful mix of imagination and passion for technology required for engineering. In the event that you do, you ought to unequivocally consider entering this field. The world dependably needs quite a few awesome engineers.

If you are having the basic qualities in you, the technical part can be taken care of by joining the best amongst the available civil construction training courses.

To an ever increasing extent, those things around us have something else in like manner other than springing from the brain of an engineer. Today, each one of those precisely designed items we depend on are interactive. They think and live and respond, and that implies they’re running software’s. The unbelievable utility of our modern things gets more from its software than its hardware. Who do you think develops that software? It’s another obligation regarding the engineers. There are numerous different motivations to end up noticeably as an engineer as this blog by nPower jobs proposes.

Our populace is maturing and the world’s demographics are altering. Throughout the following 20 years, an entire 20 percent of our populace will be prepared to resign. Average life expectancy has bounced up 30 years in the previous century. What do these numbers mean? It implies we’re going to go up against a quickly developing section of the populace that necessities care. They’ll require advanced medications and medical devices and prosthetic s. They’ll require a wide range of gadgets – and software programs – to keep up their life quality. It will be engineers that make these things they require.

The universe without bounds will be an exceedingly competitive one. Luckily, the present global atmosphere is one-sided towards competing financially instead of battling militarily. This implies diverse nations have personal stakes in making better products and more proficient infrastructures than their neighbours. They’ll require brilliant individuals to enable them to do it. They’ll require engineers.

The world won’t be changing because of demographic changes alone. We can likewise expect more individuals of each age group. The Earth’s populace remains at 7.1 billion today; 30 years from now it ought to be more like 9.6 billion. In the United States, we can hope to see the populace develop by more than 120 million in a similar time allotment. All these additional individuals will require more houses, more infrastructure, and more transportation facilities. Engineers will take part in making every last bit of it.

There are many courses that offer training on popular software’s used in civil engineering. 3D max training is one of them.

7 Things That Define Setting and Hardening Of Portland Cement

Last time, we saw a few things about mortar.

Now, In this article,

Let’s a look at few important factors that lead to Setting And Hardening Of Portland Cement:

   1.Cement’s Composition:

The mineral makes up of cement and their proportions are the primary factors influencing the setting and solidifying of cement. As said above, different mineral components will uncover distinctive qualities while responding with water. For instance, increasing C3A can accelerate the setting and solidifying rate of cement, and the heat of hydration is high simultaneously.

As a rule, if blended materials are included into the cement clinker, the counter erosion will increase, and the heat of hydration and the early quality will diminish.

   2.Curing Age:

The hydration and hardening of cement is a progressing process in a long stretch. With the expansion of the hydrating level of different clinker minerals in cement particles, gels will develop and capillary porosities will diminish, which empowers the strength to ascend with the expansion of age. It is demonstrated that concrete develops quickly inside 28 days and gradually after 28 days. Curing age also plays an important role to Setting And Hardening Of Portland Cement.

Building materials in civil engineering

   3.The amount of Gypsum:

The retardation property of gypsum is: when cement is hydrated, gypsum responds with C3A rapidly to create calcium sulfoaluminate hydrate which stores and forms a security film on the cement particles to impede the hydration of C3A and postpone the setting time of cement.

On the off chance that the amount of gypsum is pretty much nothing, the retardation influence will be unobvious. An excess amount of gypsum will quicken the setting of cement since gypsum can produce a coagulating agent itself. The fitting measure of gypsum relies on upon the content of C3A and that of SO3 in gypsum, and it likewise identified with the fineness of concrete and the content of SO3 in the clinker. The measure of gypsum should account for 3%-5% of the cement’s weight.

On the off chance that the amount of gypsum surpasses the cutoff, it will bring down the quality of cement and it can even prompt poor dimensional stability, which will cause the extended decimation of cement paste. In this manner, the national standard requires that the content of SO3 ought not to be over 3.5%.

Gypsum is known as the retarding specialist of cement which is fundamentally utilized for directing the setting time of cement and is an imperative constituent. Without gypsum, cement clinker can gather promptly by blending with water and discharge heat. The significant reason is that C3A in the clinker can break up in water rapidly to create a sort of calcium aluminate hydrate, a clotting agent, which will obliterate the typical utilization of cement.

   4.Mixing Water Content:

In the event that the cement utilization is unaltered, the increase of the blending water content will improve the amounts of capillary porosities, bring down the strength of cement paste, and augment the setting time. Thusly, in practical projects, the measure of water and cement will be changed without altering the water-cement proportion (the base measure of cement is managed to guarantee the concrete durability) when the liquidity of concrete cement is balanced. So mixing water important for Setting And Hardening Of Portland Cement.

   5.Curing Conditions:

The curing conditions have adequate temperature and dampness which is helpful for the hydration and setting and solidifying procedure of cement and benefit the improvement of the early strength. In the event that the dampness in the surroundings is extremely dry, the water in the cement will vanish, prompting lacking hydration and stopping of the hardening. Genuine cracks will happen in some cases.

In real time projects, the setting and solidifying procedure of cement products are quickened by steam curing and autoclave curing.

   6.Storage Conditions:

The wrong stockpiling will expose cement to dampness. The particle surfaces agglomerate on account of hydration which genuinely decreases the intensity. Moderate hydration and carbonization will occur because of the effect of the water and C02 noticeable all around, despite the fact that the storage is good.

   7.The impact of Admixture:

Hydration, setting, and hardening of Portland cement are compelled by C3S, C3A. And every one of the admixtures that influence the hydration of C3S, C3A can alter the performance of the hydration, the setting and solidify of Portland cement. For instance, the quickening agent operators, (e.g. CaC12, Na2S04) can quicken the hydration and the solidifying of cement and enhance its strength. Despite what might be expected, the retarding agents, (e.g. calcium lignosulphonate) can postpone hydration and be solidifying of cement and influence the advancement of the early strength.

Above mentioned are 7 important factors which have an impact on the Setting And Hardening Of Portland Cement. One should bear in mind these factors prior to using the cement and with what purpose are we using it. In short, the application of the cement.

We conclude now. In the competition of many organizations, CRB Tech Solutions developed a good name for training civil engineering students.It has earned a good name in providing the best training in Civil engineering training program and conferring civil engineering training certificate.

6 Important Mortar Properties From Engineering Perspective

Mortar is a very important constituent of the construction business. That’s why, it is important to understand the different mortar properties associated with it.

In this article, we will be doing exactly the same thing. We will see in detail, 6 important mortar properties.

You can gain structure related knowledge by joining structural engineering courses.

   Mortar Properties:

  1. Water retaining capacity:

The majority of the stone work units have typically good suction capacity, contingent upon their porosity level and dampness content and they start to suck dampness from mortar when they come in contact with it. On the off chance that units draw out excessive dampness from the mortar quickly, it can’t gain satisfactory strength, when picking up strength is reliant on the procedure of hydration in mortar. Along these lines, when binder utilised is Portland concrete or hydraulic lime, it is vital that mortar ought not part with its dampness promptly by suction-that is mortar ought to have good water retention capacity.

Water retainment capacity of cement mortar is improved by including hydrated lime or finely ground limestone or synthetic mixes known as plasticiser’s. As a rule, mortars having great work-ability have additionally great water retentivity.

As a thumb rule, lime mortar and concrete lime mortar have great water retentive while plain cement mortar made with coarse ungraded sand has low water retentivity.

  1. Work-ability:

Work-ability is the property of mortar which empowers it to be spread and applied to the masonry unit effortlessly. It additionally encourages legitimate filling of joints in the masonry. A good quality mortar would dangle from the trowel and will stream down promptly when delicately jerked. This property of mortar relies on upon properties of different fixings utilised for preparing mortar and on the strategy for blending adopted.

As a thumb rule, a mud mortar made from fine clay soil has good work-ability over the one prepared from sandy soil and a lime mortar has a superior work-ability than cement mortar.

  1. Strength:

A mortar picks up strength, to a little degree by loss of dampness that is by drying action as in mud mortar and non-hydraulic lime mortar, yet mostly by setting action of its cementitious content, to be specific lime and cement. If there should arise an occurrence of lime mortar prepared using non-hydraulic lime, which sets through carbonation, picking up of strength is at moderate speeds.

Strength of masonry relies on upon strength of the mortar. It is nonetheless, to be remembered that undue significance ought not be connected to strength of mortar at the cost of different properties of mortar.

  1. Durability:

Deterioration in mortar happens due to:

  • Frost activity before the mortar has acquired adequate strength, and rehashed cycles of thawing and freezing,

  • Delayed chemical action between sulphates that are soluble sulphates there in burnt clay blocks or in soil in contact with masonry in foundation, and

  • Entrance of dampness through cracks into the body of the masonry and resulting rehashed cycles of wetting and drying over various years and crystallisation of salts.

For security frost damage, and rehashed cycles of solidifying and thawing, it is important that mortar should pick up strength quickly, it ought to be thick and ought to have great extreme strength. lt ought to in this manner, contain sufficient extent of Portland cement, and sand ought to be well graded.

Visit a civil engineering training centre to get information about various civil related courses.

5. Speed of stiffening:

Solidifying of mortar in masonry is caused either by loss of dampness or by the setting activity of the binder utilized as a part of the mortar or due to both. The greater part of the dampness lost is ingested into the masonry unit yet some vanishes into the air. A mud mortar solidifies just by loss of dampness and there is no setting activity of its clay. A lime-sand mortar produced using non-hydraulic lime (limes with grade C and D) likewise solidifies in early stages by loss of dampness yet it has additionally exceptionally mellow and slow setting action because of carbonation. A concrete mortar stiffens chiefly through setting action of cement.

6. Resistance to rain penetration:

It has been revealed that rain infiltration through units and mortar is not extremely noteworthy and primary wellspring of rain penetration is through cracks in masonry.

These cracks are for the most part caused by shrinkage of units and mortar upon drying, thermal developments of units and mortar and inescapable slight settlement to which each building is subject to. Along these lines, from the view point of rain penetration, holding property of mortar is of incredible significance. It has been watched that if mortar is not exceptionally solid, on the off chance that it picks up strength gradually, and on the off chance that it has good bond with units, movement of units because of shrinkage, temperature fluctuations and settlement of establishment get suited, all things considered, inside the mortar and cracks are, along these lines, thin and equally dispersed. Thus, masonry has much better imperiousness to rain infiltration.

These were a few properties of mortar that hold significance from the engineering perspective. They need to be considered.

An Overview About Low Cost Housing

Low cost housing is a new concept that deals with effective budget and use of techniques which help in lowering the cost of construction through the use of locally available materials and improved skills and technology without sacrificing performance and life of the structure. There is big misconception that low cost housing is suitable for only sub standard works and they are constructed by using cheap building materials of low quality. The fact is that low cost housing is done by good managing the resources, well.

Building Cost

In a low cost housing, building material cost is less as you can make use of the locally available materials and also the labour cost can be reduced by properly making the time schedule of our work. Cost of reduction is achieved by selection of more efficient material or by an improved design.

Areas from where cost can be lowered are:-

1) Lower plinth area by using thinner wall concept.

2) Use locally available material in a new form like soil cement blocks instead of burnt bricks.

3) Use energy efficiency materials which need less energy like concrete block instead of burnt bricks.

4) Use eco-friendly materials which are substitute for conventional building components like the R.C.C. Door and window frames instead of wooden frames.

5) Pre plan every element of a house and logically sketch the design procedure for lowering the size of the components.

6) Each component shall be checked whether if it’s necessary, and then the component would be used.

Cost reduction through adhoc methods
Foundation


Usually, the
foundation cost comes to about 10 to 15% of the total building and the foundation depth of 3 to 4 ft. is adopted for single or double store building and also the concrete bed of 6″ is used for the foundation which could be avoided for Low cost housing.

It is recommended to adopt a foundation depth of 2 ft. for normal soil like and use the uncoursed rubble masonry with the bond stones and good packing.

It is further suggested adopt arch foundation in ordinary soil for effecting reduction in construction cost up to 40%.This kind of foundation will help in bridging the loose pockets of soil which occurs along the foundation.

In the case black cotton and other soft soils it is recommend to use under ream pile foundation which saves about 20 to 25% in cost over the conventional method of construction.

Plinth

It is advisable to adopt 1 ft. height above ground level for the plinth and might be constructed with a cement mortar of 1:6. The normal plinth slab of 4 to 6″ could be avoided and instead brick on edge could be used for lowering the cost. By adopting this procedure the cost of plinth foundation could be reduced by about 35 to 50% which will help for Low cost housing.

Walling

Wall thickness of 6 to 9″ is suggested for adoption in the construction of walls and 41/2 ” for inside walls. It is advisable to use burnt bricks, after being immersed in water for 24 hours and then used for walls.

Rat – trap bond wall


It is a cavity wall construction which has an advantage of thermal comfort and lowers the quantity of bricks required for masonry work. By adopting this method, it is possible to lower in the material cost of bricks by 25% and about 10to 15% in the masonry cost.

Concrete block walling

Using concrete block masonry the wall thickness could be reduced from 20 cms to 15 Cms. Concrete block masonry saves consumption of mortar, speedy construction of wall results in higher output of labour, plastering could be avoided thereby an overall saving of 10 to 25% can be achieved.

Soil cement block technology

It is an alternative method of construction of walls using soil cement blocks in place of burnt bricks masonry.

Doors and windows

It is suggested not to use wood and instead concrete or steel section frames are suggested for saving in cost up to 30 to 40%.

Lintals and Chajjas

The traditional R.C.C. lintels are very costly and could be replaced by brick arches for small spans and save construction cost up to 30 to 40% over the traditional method of construction.

Roofing

Normally 5″, thick R.C.C. slabs is used for roofing of residential buildings.

Filler slabs
They are normal RCC slabs where bottom half are replaced by filler materials like tiles, bricks, cellular concrete blocks, etc. These filler materials are so placed as not to compromise structural strength result in replacing unwanted and non-functional tension with concrete, thus results in economy. These are safe and aesthetically pleasing pattern ceilings and also don’t need plaster.

Jack arch roof/floor
They are easily constructed, saves cement and steel, are more good in hot climates.

Finishing Work
The finishing cost for sanitary, electricity, painting etc., varies depending upon the kind and quality of products used in the building and its cost reduction is left to individual choice.

Conclusion
The above list of suggestions for lowering construction cost is of general nature and it varies depending upon the nature of the building to be constructed, owner’s budget, geographical location of construction, availability of the materials, etc.

But it is necessary that a good planning and design methods must be adopted by utilizing the services of an experienced engineer or an architect for supervising the work, to achieve overall cost effectiveness to the extent of 25% in actual practice.
