Insulation refers to an energy savings measure, which provides resistance to heat flow. Naturally, heat flows from a warmer to a cooler space. By insulating a house, one can reduce the heat loss in buildings in cold weather or climate, and reduce the heat surplus in warmer weather or climate.

What is insulation used in civil?

The word 'insulation' refers to the material that is interposed. Insulation may be used in the construction industry for a number of different purposes: Thermal insulation to prevent the transmission of heat, typically between the inside and outside of a building.

Construction Site Development

Construction site development refers to the improvements done to prepare a site for construction. It is the first and most crucial step towards a successful commercial construction project. Why? Initiating a construction project without proper site development may interfere with the project’s plan midway, hinder the approval of building permits, and poses significant financial and even legal risks for the project developer or investor.

The Construction Site Development Process

Now that you know why site development is crucial, here is a breakdown of the steps that must be taken before the commercial construction project begins;

1.    Site Surveying

If a surveyor does not mark out your site, construction cannot begin. A survey needs to be done to determine the correct site and line where the project should be built. A survey also enables the contractors to verify the appropriate horizontal and vertical location of the proposed structure.

2.    Soil Testing

Soil testing is one of the most critical steps in the construction site development process. It involves the assessment of the composition and the condition of the soil on site. The test is done to evaluate the soil’s structural integrity and determine whether it can hold the weight of the proposed building, its water drainage capability, and how well it can withstand harsh climatic conditions in the future. Soil testing is a legal and inescapable step in site development.

Unfortunately, if the soil is marked as unsuitable, there’s no other choice but to look for a different site. Based on the test, the site’s soil may fall in either of the following categories:

• Class A: this type of site soil consists of sand and rock and is usually not affected by moisture. Class A soil is acceptable, which means the site development process can continue.
• Class S: Consists of slightly reactive soil and is somewhat affected by moisture changes. Construction can also continue, but precautions must be taken.
• Class M: consists of moderately reactive soil and is susceptible to moderate ground movement due to moisture changes
• Class H1 and H2: If your soil test puts you in this category, then the site has highly reactive soil and will experience high ground movement due to moisture.
• Class E: This is exceptionally reactive soil, and will experience extreme ground movement. Not suitable for construction.
• Class P: mostly soft soil such as clay and loose sand. It is also extremely reactive and is subject to abnormal moisture levels. Not suitable for construction.

3.    Site Clearing

Before construction begins, the ground needs to be clear and completely leveled. This means clearing any trees that may be on it and any underground utilities that may hinder the construction process. Sometimes, the site may even have buildings in good condition. These need to be demolished and cleared from the site.

4.    Site Investigation

Site investigation is similar to soil testing only that this time, the geotechnical investigators do it to evaluate rock composition and groundwater conditions on the site to determine how the foundation of the proposed project should be built.

5.    Site Plan Design

After surveying, soil testing, site clearing, and site investigation, the project contractors and architects must create a site plan. Also known as the plot plan or the blueprint, the site plan is a drawing that shows where what will be. It shows what exists on the site and what will be on it after the proposed project is complete. For instance, the plan shows where the building will be on the site, where the access road will be constructed, and where all the underground utilities such as septic systems will be installed.

A site plan is crucial as it proves to government officials that both state and local building regulations and codes were adhered to during the construction of the proposed building. It also serves as a map in the future should you need to make any additions or changes to the proposed building.

Industrial Sheds

Structural sheds used in industries to store raw materials or for product manufacturing, known as Industrial Sheds. These industrial sheds are used for warehouse, factories, godowns, workshops, storage plants etc. Industrial Sheds can be small or big in size depending on the requirement. Various steps are involved in construction of Industrial Sheds like Site Inspection, Planning, Design, Components Fabrication, Installation etc but the most important step is Components fabrication, which should be of best quality for gaining and maintaining the standards, endurance and various other benefits of an perfect industrial shed.

­KAMAL INSULATION is one of the steel fabricators in India which not only at its best on producing best quality of steel, but also specializes as Industrial Sheds Manufacturer in india in last few decades. One of our best creations in field of industrial building manufacturing is Pre Engineering Buildings / PEB.

Industrial pipe racks

A Pipe rack is a structure designed and installed specifically to support multiple pipes, where an adequate building or structure is not available (mainly outside the building).

Pipe racks are necessary for arranging the process and utility pipelines throughout the plant. It connects all the equipment (installed at a different location) with lines that can not run through adjacent areas.

Pipe racks are also used in secondary ways, as it also carries the electrical wire, instrument wire, fire fighting systems, lights, etc. Air-cooled or fin-fan type heat exchangers are often supported above pipe racks to reduce the plant space requirements.

Pipe Rack Type

There are mainly three types of Pipe rack-

1. Steel Structure Type
2. RCC Structure Type
3. Sleeper Type (This is also called Pipe Track)

Steel Structure Pipe Rack

A steel structure type pipe rack is preferred for lines up to 12″ or 300 MB.

RCC Structure Pipe Rack

An RRC structure-type pipe rack is preferred for lines above 12″ or 300 MB and up-to 30″ or 750 MB. It is also used if the pipe rack height is above 10 m.

Sleeper Type Pipe Rack or Pipe Track

Sleeper type pipe racks are mainly used for pipelines above 30″ or 750 MB.

The most commonly used shapes for racks are L/T/U/H/Z. The shapes are mainly decided based on space availability and optimized use of space and material.

Documents Required for Pipe Rack Development

Pipe Rack Designing involves considerable planning and coordination with other engineering groups to deliver error-free work. Following documents or engineering deliverables are required-

• PFD (Process Flow Diagram)
• P&ID (Piping and Instrumentation Diagram)
• Line List
• Line Routing Diagram or GAD
• Over All Plot Plan
• Unit Plot Plan
• Equipment Layout
• Piping Material Specifications
• Client Specification
• Fire-Proofing Information

Trenching

Trenching is a construction method that involves digging a narrow trench in the ground for the installation, maintenance, or inspection of pipelines, conduits, or cables.

According to the Occupational Safety and Health Administration (OSHA), excavations are designated as trenches when they are deeper than they are wide, not exceeding 15 feet (4.5 meters) in width. Trenching is considered to be among the most hazardous construction activities as it can involve dangers such as cave-ins, falls, hazardous atmosphere, and heavy machinery-related accidents.

Pros of Trenching

Municipalities are accustomed to the traditional trenching process and are equipped with the appropriate equipment. Even though many municipalities have begun using the less disruptive and more cost-effective method of trenchless construction and rehabilitation, the situation still arises where trenching is inevitable.

For example, where pipe deflection has damaged the pipes, trenchless rehabilitation methods may not work and trenching may have to be done in the affected area to rectify the problem. The only way to remedy a line belly is to excavate using the conventional trenching method, remove and completely replace the pipe after providing adequate slope and proper bedding.

Cons of Trenching

Digging trenches for pipeline installation requires the use of heavy machinery and heavy vehicles such as dump trucks that require a lot of fuel and leave a huge carbon footprint. Trenching also requires a backfill that uses additional use of vehicles and machinery.

It also causes a lot of surface disruption and obstruction to people and vehicle movement. Even the narrowest trenches present danger of falls and injury.

Semi-trenchless Technique

Trenchers are used for digging trenches and laying cables, conduits, or pipes of diameter up to 63 mm and at a depth up to 1.5 m. The pipe express method is a semi-trenchless method that is used for the near-surface installation of pipelines of lengths up to 1000 meters and diameters from 800 mm to 1500 mm.

The pipe express method combines the use of the tunnel boring machine (TBM) and a compact trenching unit. This method consumes about 70% lesser ground space than open trenching, and the entire process is remote controlled and guided by a trained operator.

Earth Work

Earthwork is a process that involves the movement of a portion of the earth’s surface from one location to another and in a new position. It also involves the establishment of a new position for earth material like sand. Earth movement also involves the creation of a new desired shape and physical condition for the earth material being moved. It is also called Excavation

 

Earth work involves a lot of processes and because of this, i am going to classify earth work to include the following types:

 

Types of earth work Or Excavation

1. Topsoil excavation

2. Earth Excavation

3. Rock Excavation

4. Muck Excavation

5. Channel excavation

6. Footing excavation

7. Burrow Excavation

8. Bridge Excavation

9. Unclassified Excavation

 

Because of the fact that there exist a wide variety of soil encountered on site, many jobs to be done with such soils also, You are therefore going to be exposed to various equipment and methods used in earth work but before this, lets talk about the types of excavation

 

Road

The road is a paved way or a route or a thoroughfare that drives you to reach your destination through vehicles. In this post, we show a type of road and a description of each road and construction step of Earth road.

Types of Roads in civil engineering

• Low-cost Road
• Earth Road
• Gravel Road
• Kankar Road
• Murrum Road
• Brick Aggregate Road
• Concrete Road
• WBM Road
• Bituminous Road

Types of Roads

Low-cost road

The road which entails very little cost in their construction and which serves the needs of the light traffic is called a low-cost road.

Construction of good pavement involves very large costs. In villages and undeveloped areas, the immediate need is not of the good road but such roads which may serve the traffic needs.

As the traffic increases on the road, as a result of the development, existing roads may be improved upon to serve the needs of the increased traffic needs is called the phased development, facilities are provided just sufficient to the present needs of the road. Sometimes as the traffic on the road increases, roads are improved further.

What is Earth roads?

Earth roads

This road is the cheapest type of road and is used at places where traffic is rather rare. The pavement structure of this type of road is made totally from the soil available at the site.

In phased development or stage construction of road, this in fact is the first stage of construction. The performance of these roads mainly depends upon effective maintenance and drainage.

A defective drainage system can spoil any type of road that to talk of earth road. To carry out effective drainage of this road.

The camber is provided ranges between 1 in 20 to 1 in 25. Steep cross fall helps in the immediate drainage of rainwater from the surface of the road and maintains its stability.

Pre-Engineered Builiding

The Pre Engineered Building is a metal enclosure building that includes a structural frame and standard roof and wall support which is factory made and is erected at the site. Pre-Engineered Building is a new manufacturing concept replacing traditional manufacturing. PEBs is seen as a breakthrough in the construction industry, resulting in less construction time, cost-effectiveness, high quality, low maintenance, consistent span. Pre-engineered buildings meet one of industry’s most critical criteria that is wide, column-free areas.

There has been a substantial rise in Pre Engineered buildings in recent years. Due to rapid construction developments and an increase in the need for quick-track construction in India.

Know About Pre Engineered Buildings:

Primary Member:

Primary framing of a PEB is an arrangement of built-up I-shaped steel members & framing consisting of trusses or castellated beams etc. all structural elements that pass the load to the base and consist of End wall frames. End walls are either designed with economical bearing frames or with rigid frames. Such frames are reinforced with wind bracing, connecting bolts, if necessary anchor bolts. Instead of individual parts, a combination of these three components and weather covering sheeting results in robust steel constructions. In traditional structures, separately built and stand-alone frames are individual columns and trusses that result in a large, heavy structure.

Secondary Member:

The secondary structure consists of roof purlins, wall girts, struts, and clips, etc. which help and support the primary framing of roof and wall panelling. The secondary framing method consists mainly of Z and C purlin types of various sizes. The first method contains rafters and columns, while C and Z Purlin have been involved in the preservation of the structure. In contrast with traditional beams, channels and angles the application of purlins help to reduce costs. For the overall stability of the building structure, Purlin / Girts transfers force and instants from one frame to another and functions as a framing device for weather covering sheeting needs. Purlins are available in various lengths and thicknesses, ensuring no cost of production and wastage. Purlins can be easily mounted, resistant to corrosion, lightweight and robust. 

Roof and Wall Panels:

With this group typically comes tin shades & curtain wall crafted from glass & rolled steel sheets.  For the transfer of wind force and other acting loads, the frame to the foundation is used to convert the trajectory of forces in order to reduce the effect of the forces.

There are also other options, such as special roofing sheets, that will help minimize energy usage, in particular in colder regions. It is no surprise that PEBs are the future of construction and manufacturing worldwide with benefits like less construction time, lower the cost of materials and function, increased energy quality and sustainability through modular design.

 

RCC Tank works

The Full form of RCC is Reinforced Cement Concrete. RCC is a process when plain cement concrete which is a mixture of cement, coarse aggregate and fine aggregate is reinforced with steel bars. It is generally a concrete that contains steel bars, which is also known as rebars or reinforcement bars. This combination of RCC works very well, as concrete is very strong in compression and steel is very strong in tension. It is easy to produce at site and also inexpensive.

An RCC building means the main structural members of the building, viz, beams, slabs, foundations, and columns are made up of RCC (Reinforced Cement Concrete). There are various ratios of RCC, generally 1:1.5: 3 and 1:2:4 ratios are used in construction work. Where cement concrete ratio 1:1.5:3 is used; it means 1 part of cement, 1.5 parts of fine coarse/aggregate sand and 3 parts of coarse aggregate is mixed. RCC is basically used in structures to provide the tensile strength that the concrete is ineffective to handle.

It is used in storage structures like water tanks, dams, tunnels etc. It is also used to build heavy structures like towers, walls, bridges, or under water structures, sky scrapers and tall structures.

Reinforced concrete water tanks are constructed for storing water. The design of reinforced concrete water tank is based on IS 3370: 2009 (Parts I – IV). The design depends on the location of tanks, i.e. overhead, on ground or underground water tanks. The tanks can be made in different shapes usually circular and rectangular shapes are mostly used. The tanks can be made of reinforced concrete or even of steel. The overhead tanks (elevated tanks) are usually elevated from the rooftop through column. In the other hand the underground tanks are rested on the foundation. In this article, Design requirements of reinforced concrete water tanks are discussed.

Types of RCC water tank 

Based on water tank location

Underground tanksTank resting on grounds

Overhead tanks*

Based on water tank shape

Rectangular tank

Circular tank

Spherical tank

Intze tank

Circular tank with conical bottom

Basis of concrete water tank design

RCC water tank design should be based on sufficient resistance to cracking to avoid leakage and adequate strength. For achieving these following assumptions are made:

• Plain section before bending remains plain after bending
• Both concrete and steel are perfectly elastic and modular ratio value has a value given in IS 456- Table 21.
• In calculation of stresses. Both for flexural and direct tension or combination thereof relating to resistance to cracking, the entire section of concrete including the cover together with reinforcement can be taken into consideration provided that tensile stress in concrete limited to values provided in Table 2.
• Neglect concrete tensile strength during strength calculation.
