As soon as the planning for construction is finished and the forms are arranged, you should examine the type and amount of required concrete.
In order to measure the amount of concrete, just multiply the length of the slab with the width of the slab and divide by the exact number relating the depth from the chart provided under then round up to the next quarter yard.
Defining Mix Design
It is very important to determine the perfect mix for your job. Concrete specifications include Strength (PSI), Slump (mainly the thickness), Fiber Mesh, Chemical Additives as well as a Concrete Pump if needed. Generally 80% of all concrete poured remains 3000 Psi slab mix or 3000 psi pump mix. Other mixes range from 3000 Psi – 5000 Psi mixes, Fine Grout, C-476 Cell and Flowable Fill.
Compressive strength is described in psi. If it contains more psi, the strength and durability will improve. Besides, the set time will be lower with the higher PSI. Usually 80% of the slabs contain will 3000 psi.
It is suggested to use a slump of 5-6 inches (+/- 1″) as a slump superior than 6″ may delay the time and one has to wait prior to finishing, specifically in cool weather. Besides, it can enhance the possibility for shrinkage cracking.
Reinforcing Wire Mesh & Fiber MeshWhile curing of concrete, the water in the concrete starts to bleed off and the slab will begin shrinking just slightly. Shrink can lead to cracks because the slab drives across the base material. These cracks are known as shrinkage crack. With use of reinforcement like wire mesh, rebar, or fibers, the cracks can’t be avoided. It can only retain the concrete organized at the time of cracking and stop parting or vertical dislocation.
So, it is very essential to place wire or fiber mesh in the slab.
Fiber mesh is applied to substitute wire mesh in most cases, apart from the first 15’ apron of a driveway. (Verify your local codes) Reinforcing wire mesh is arranged in the slab area before pouring the wire mesh is set on mesh-ups which belong to 2” plastic chairs specifically created for wire mesh. Wire that rests on the ground and is not retained in the middle of the slab by mesh-ups, will not be fruitful for shrinkage cracks. Fiber mesh is included into the mix while pouring and is simpler to use.

Now-a-days manufactured roof trusses are used extensively for new homes in USA to form the roof. In traditional framing, the rafters and ceiling joists are used and these are replaced in prefabricated trusses. The trusses are utilized to facilitate the general contractor for building homes which contain more complicated roof and ceiling designs maintaining superior speed and precision.
Fewer unskilled carpenters are employed to build the trusses by incurring low labor costs. These cost savings will minimize the price of almost any new home to be developed. Therefore, prefabricated trusses are mostly suitable for modern builders for their bottom line as compared to traditional roof framing.
Benefits of Prefabricated Trusses
- Trusses extent longer distances and disregard the requirement for inside load bearing walls.
- Cost effective as compared to stick roof framing as they are created with shorter lengths containing two by four stock as contrary to the larger framing members associated with traditional rafter and ceiling framing.
- Trusses are specially created for almost any ceiling or roof combination essential for modern custom homes.
- The proficient engineers design these trusses to satisfy the roof load and building code requirements.
- Trusses can generally be formed in one day. Therefore, the construction time minimized significantly. The inside of the new home is uncovered outside weather conditions.
- Inexperienced carpenters will also be able to construct trusses and less labor costs are required.
The Common Roof Truss
The common truss is acknowledged by its triangular shape and will frame the bulk of any new home truss package. Common trusses include seven primary portions as below:-
Top chord - To which the roof sheathing is used.
Bottom chord - To which the drywall or other finished ceiling is associated.
Bearing point - Where the common truss is created to be placed on the outside bearing walls.
Web supports – These are used to retain the top chord in the exact position, at intermediary points from the highest to the bearing point.
King post - It is applied to facilitate support to the heighest or top of the common truss.
Metal gussets – These are applied where the web supports and king post overlap the top and bottom chord and at the bearing point.
Tail of the truss is applied to produce the eave or overhang and arranges a way to assign soffit and fascia.

(1) Raw materials utilized in Concrete Blocks :
The primary materials for developing the concrete blocks are aggregates, cement and water. Different types of aggregates are applied with changeable degree of success and they consist of crushed stones, gravel, volcanic cinders, foamed slag, furnace clinker, etc. In order to choose the aggregates, the factors like weight, texture or composition of the unit designed should be considered. The stability, texture and low-cost of the concrete block are subject to the grading of the aggregate cautiously. The cost will be reduced if locally accessible aggregate is used. The ordinary Portland cement is utilized for raw material. The required water should be the normal potable water.
(2) Concrete blocks manufacturing process:
The completely automatic plants are used to develop concrete blocks with superior strength. These automatic machines can made superior quality concrete blocks. But huge capital investment is required to set up & operate these machines. The transportation cost from the production area to the place of actual use will also be reduced for concrete blocks if the manually operated machines are installed at construction site itself.
The following manufacturing process is required for developing the concrete blocks :-
(i) Choice and ratios of ingredients: The primary factor for selecting the ingredients is the desirable strength of the block. If the coarse aggregate is mixed in perfect ratio, the strength of the quantity of cement applied will be superior.
(ii) Blending of ingredients: The aggregates, cement and water should be blended in a proper way. The mixing should be done through a mechanical mixer. While mixing manually, great care is necessary to check that the cement and aggregates are initially blended comprehensively in dry state and the water is then included slowly.
(iii) Positioning and vibration: The mixed concrete material is delivered into the mould box up to the top level and check carefully that the box is filled uniformly. The vibration of concrete is performed until it is set evenly in the mould box.
(iv) Curing: The block is drenched with water after around one day of casting and it should be sustained for at least 7 days and if possible up to 28 days. If the time for curing extends for a prolonged period, the block will be superior.
(3) Benefits of concrete blocks:The application of concrete blocks as a masonry unit is found on several construction sites due to the following benefits:
- It extends the carpet area of the building due to the small width of concrete block with regards to the brick masonry wall.
- It offers superior thermal insulation, improved fire resistance and strong absorption capacity.
- It can save major agricultural land which is applied for manufacturing bricks.
- The blocks are developed in an efficient manner so that the vertical joints can be taken back automatically and so the time spent for the careful supervision is minimized.
- The process for developing concrete block masonry is simpler, rapid and stronger as compared to the brick masonry.
- The shape and size of the concrete block is very accurate and it simplifies the work of a mason.
- As the numbers of joints are minimized, the time is saved for developing the mortar.
- The utility will be augmented by creating the reinforced concrete block (RCB) masonry units. The blocks are provided with two holes for arranging perfect reinforcing bars and the structure with RCB units could carefully withstand wind and earthquakes, if so designed. The conventional beams and columns are totally removed and the structure with RCB units will have a superior appearance.

Grillage Foundation design is mostly suitable for heavy structural loads from columns, piers or beams which are essential to transmit bearing capacity of a soil relatively inferior.
The grillage foundation can easily disperse the load over a broad area of the subsoil. This foundation facilitates to resist deep excavations because the required base area is arranged for the load of the transmission. The foundation depth is restricted from 1m to 1.5m.
The grillage foundation contains two or more tiers of beams placed at proper angles to disperse the load over a extensive area.
Usually, this type of foundation is undertaken toward heavy structure columns piers and stanchions. Grillage is made with steel I I section (R.S.J) placed in single or double large.
The second larger - The number of R.S.J.S and they’re spaced separately based on load of the structure and the bearing capability of the soil.
Ground Improvement with inclusion of Load or enhancing operative stress
When load is delivered on the ground, it is compressed. The range and required time may vary according to the placing of ground particles, on the degree of saturation as well as smooth draining of the soil. If load is delivered for loose and specifically unsaturated fills, it can cause quick settlement.
In order to build a grillage foundation, a trench of the essential width and depth is excavated. The trench surface is leveled and rammed. Above the rammed surface, a cement concrete layer is applied. It should be condensed properly to transform it water-resistant. R.S.J.S contain necessary dimension that are place at consistent gaps. For implanting the lower flanges of the R.S.J.S into the concrete, rich cement mortar is poured. The pipes and bolts are used to attach the R.S.J.S collectively. The bolts are pushed into web of the R.S.J.S.
G.I. pipe pieces are arranged among R.S.J.S, and a long bolt is passed over all the holes and pipes. This will attach the R.S.J.S collectively and develop a solid mass.
Grillage Foundation Types
1.Steel Grillage Foundation
Steel Grillage Foundation is developed with steel beams and it is structurally called rolled steel joists (RSJ), applied in two or more tiers.
2.Timber Grillage Foundation
Timber grillage is undertaken for heavy load wood column or masonry wall. Benefits of Grillage Foundations.
Steel grillage foundation is more useful for contractors as compared to wooden grillage.
Installation Speed – Contractors can make significant savings in time through a grillage foundation.
Suitability – Grillage foundations are mostly used in place of poured concrete and huge time is saved because of smooth installation process.
Costs Reduction – Contractor can obtain discount in cost as there is least possibility for disarrangement of transport infrastructure.
Multipurpose foundation solution – The technology supports various applications.

This construction video briefly explains how to estimate the concrete quantity essential for pouring a L shaped concrete slab in the ground having splayed edge beam and a rebated edge.
Concrete slabs refer to floor systems of concrete and steel reinforcing. These are built on the ground. There are different types of concrete slabs which range from slab on ground, stiffened raft slab, footing slab, waffle raft slab, infill slab.
Edge rebates should be placed in the edge-stiffening beam when exterior walls belong to masonry veneer or complete masonry. A check out from the edge beam will produce a flange for the brick to hinge on under the top of the slab. This extra protection is taken to stop surface run-off water from inflowing the building.
The rebate must be flashed and weep holes are arranged in the masonry. The weep holes should be placed at a least distance of 1.2 metres so that the water can be blown out and left from the wall and the slab.

A design engineer should take liabilities for ensuring the structural security of the design, details, checking shop drawing.
Detailing is also a vital part of any construction as perfect detailing of engineering designs is required in the planning and engineering phase for proper accomplishment as well as safety of the structures. Defective connections or detailing may lead to collapsing.
Detailing plays an important role for the steel structures as well as for the RCC members as it remains the translation of all the mathematical expression’s and equation’s results.
For commonly used RCC members, the detailing can be segregated for Slabs-with or without openings.(Rectangular,circular,non-rectangular-pyramid slab,triangular etc) balcony slab, loft slab, corner slab etc
Beams – With or without openigs.(Shallow & deep beams)
Columns – (Rectangular,l-shape,t-shape, circular,octagonal,cross shape etc)
Detailing for gravity loads differs with the lateral loads particularly for the SEISMIC FORCES.
A different types of detailing is essential for the Rehabilitation and strengthening of damaged structures.
For perfect DETAILING, the following processes are necessary:-
Make drawings perfectly and label each bar & show its shape for accuracy
Cross section of retaining wall is collapsed instantaneously due to placing of soil backfill that contains ¼” dia instead of 1-1/4” dia. The error may happen as proper rebar dia was covered with a dimension line.
- If required, generate bar-bending schedule.
- Specify perfect cover-clear cover, nominal cover or effective cover to reinforcement.
- Select detailed location of opening/hole and provide sufficient details for reinforcements just about the openings.
- Apply the bars and spirals which are generally available. For a single structural member, the number of various sizes of the bars should be lowest.
- There should be clear information in the drawing for the grade of the steel.
- Deformed bars should contain at their ends.
- Show distended details at corners, intersections of walls, beams and column joint and at parallel situations.
- Blockage of bars should be avoided at points where members intersect and make certain that all rein. Can be properly placed.
- In the case of bundled bars, lapped splice of bundled bars shall be made by splicing one bar at a time; such individual splices within the bundle shall be staggered.
- Make sure that hooked and bent up bars can be placed and have adequate concrete protection.
- Indicate all expansion, construction and contraction joints on plans and provide details for such joints.
- The placing of construction joints should remain at the point of minimum shear roughly at mid or near the mid points. It is developed vertically and not in a sloped manner.

Demarcate the deck area with string and "batterboards" and ensure that that it is square. Batterboards belong to boards hammered on the ground just outside the corners of where the deck is situated. The string can visualize the size and look of the completed deck and also help in simplifying the process for excavation and post placement.
SQUARING WITH STRING
1. Assign string to house and/or batterboards to ensure its level.
2. Label the string 3' from the corner in one way and 4' from the corner in other way by applying a felt tip marker.
3. One can get a perfect triangle if the diagonal that connects these 2 points is 5'. The angle at the corner is 90°.
Note: In order to get the 5' measurement, move the string that is associated with the batter board to the left or right till it becomes perfect.
Make the site ready. A spade or sod cutter is used to take away sod to a depth of 2 or 3 ". Expose an area roughly 2 ft. bigger compared with the planned deck. It's dubious that grass can develop in the shadow of your deck, it is necessary to shift the sod to a uncover spot in your yard where it is mostly suitable. Be careful so that weeds and unnecessary vegetation can’t be developed over the deck. Cover the area with a sheet of polyethylene film. Just cut this to embed posts in the ground. As soon as the posts are set up, use gravel, pebbles or wood chips to cover the sheet.
While attaching your deck to a prevailing structure, you should focus on a ledger/header.The position of the ledger/header finds out the level of the deck floor. Therefore, ensure that it is placed at the exact height horizontally.
While binding ledger/header boards to wood, the ledger must be arranged safely with bolts via the wall or lag screws. To resist water behind the ledger board, apply aluminum flashing. It must be inserted under the siding and bent down over the ledger, then down the face of the ledger board. For aluminum or vinyl siding, cautiously trim siding away from house to fasten ledger/header board directly to the house. It is also required to apply the bottom edge pieces of the siding over the deck to refinish the lower edge to save them. It is assumed the joists are suspended from the ledger and not supported on it. Ensure you consider the height of your deck boards while calculating the location of the ledger. (Usually, just 1 ½ inches down from the final height of the deck.)

Precast Concrete Homes is now considered as a very popular construction method all through the globe as they are exceedingly solid and durable. Various precast concrete panels are used to develop a building. It is possible to build a standard 4 bedroom home just in 8 weeks. Any building can be constructed 16 weeks quicker as compared to brick veneer. This construction method facilitates the builders to complete more homes in each year.
Precast Concrete Homes are formed with the concrete walls which offer superior thermal and acoustic insulation to make the home stronger. They contain good resistance capacity to cyclones, floods, earthquakes and ground movements. Besides, they are also mold and mildew resistant related to a customary wood or brick home. They are also very useful for bushfire prone areas because they surpass the Australian Bushfire Standard (AS3959) for the utmost “Flame Zone” category.
Total precast homes contain no beams and columns in the basement which offers stretched clear spans for a very flexible design. Precast floors are very useful if they are amalgamated with radiant heat.

Get brief ideas on bending moment and shear force induced in beam section through this construction video tutorial. Also learn the detailed process to draw SFD and BMD on the basis of this type of foundation.
A bending moment refers to the reaction induced in a structural element while using an external force or moment to the element for bending it. Beam is generally considered as the elemental structural element that is dependent on bending moments. Shear Force alias shearing force can be described as a force that functions on a substance in a perpendicular direction to the extension of the substance. Shear forces frequently leads to shear strain. Defiance to such forces in a fluid is connected with its viscosity.
If the beam is loaded at random, the internal forces and moments are formed and the shear force and bending moments occurs to examine the beams further.
Sheer force diagram (SFD) and bending moment diagram (BMD) are the most vital process for making initial design calculations of structural or machine elements.

Reinforced concrete is a popular structural material that is utilized extensively in construction engineering. Concrete is very powerful to withstand compressive stress but it is weak in tension. In order to combat tensional stresses, steel is required in concrete. The reinforcement in concrete refers to simple bars or rods bend and connected to a specified schedule with stirrups. The minimal diameters of bars which are utilized at site were Y10, Y12, Y16, Y20, Y25 and R6.
Steel is available in two basic types.
1. Mild steel (250 N/mm2)
2. Tor steel (460 N/mm2)
Implication of Reinforcement in Drawings
Engineering drawings is a language to disclose information thoroughly. So, there is a standard like 5Y10- 001- 150 to specify reinforcement in drawing such as, 5Y10- 001- 150:-It signifies 5 Number of Tor steel, 10mm Diameter, Bar mark 001, At 150mm CRS. At bottom face.
Bar location is changeable as below:
Notation for Slab :-
T1 -Top outer layer, T2 -Top second layer
B1 -Bottom outer layer, B2 -Bottom second layer
Cutting and Bending of Bars Reinforcement bars are preserved, sliced and bent in a steel yard in the site. Reinforcement bars are sliced into the desired lengths and bent into requisite shapes demonstrated on the bar schedule either by hand or through machinery.
Under manual processes, laborers applied the bar bending bench upon which robust nails and GI pipes are set with proper lengths to bend the bars for being utilized for smaller diameter bars. The larger diameter bars are bent through bar bending machine. Once the bending process is completed, all reinforcement bars are stacked and perfectly numbered as stated by the bar mark to avoid any issue at the time of fixing them.
