Ultimate Roadmap For Building Cost Estimation & Work Process

The Ultimate Roadmap For Building Cost Estimation: 13 Items Should Be Included:

There are many steps involved in building cost estimation for your project, but it doesn't have to be difficult. Find out how you can use this roadmap to quickly break down the process and get started.

Estimation is a key component of any civil engineering project. Before taking on any project, the builder must be aware of the estimated amount of work and associated costs. Also, it is important to be able to estimate the costs of all items in the project.

Permits: 

Building a house is a costly endeavor that requires plenty of forethought and financial preparation. One of the first steps in the home building process is to obtain the necessary permits from your local municipality. The cost of these permits will be included in your overall budget for the project.

 

The price of building permits varies widely depending on the type of construction you are planning, as well as the location of the build. For example, a single-family home in a rural area will likely have much cheaper permit fees than an office building downtown. Check with your local government offices to get an estimate of what your permit costs will be.

Keep in mind that failing to obtain the proper permits can result in significant delays and additional costs down the road, so make sure to factor this into your budget from the start.

Building cost estimation involves several factors, as outlined in this article

1. Clearing the Site

Clear vegetation, bushes, and other organic materials that are on top of the soil should be removed and measured in square meters.

2. Soil Excavation

Assuming you're not planning to live in a cave anytime soon, excavation is going to be one of the first steps in constructing your home. The cost of excavation will depend largely on the size and complexity of your home's foundation as well as the terrain of your building site.

Excavations are made to excavate foundation trenches that measure the exact dimensions of the foundation. These trenches' sides and bottom are leveled transversely as well as longitudinally. Cubic meters is the unit.

Excavating for a typical small home(150 sq yards) foundation can range from 7000-10000rs(Note: Depending upon the number of pillars and soil conditions, if rock exists it will cost more), while a more complex foundation could cost upwards. If your building site is particularly hilly or has a lot of large rocks that need to be removed, you can expect to pay on the higher end of that spectrum.

3. Earthwork for Filling

This involves filling the excavated area to the required depth with soil taken from the site or using soil brought from elsewhere. The quality and type of soil used to fill the excavations will determine how much. It is measured in cubic meters.

You can subdivide earthwork into the following:

  • Filling in the foundation
  • Filling with plinth: This is the depth of the filling from the ground up to the floor.

4. Foundation

The foundation is one of the most important parts of your house. It supports the entire structure and keeps it from settling into the ground. The type of foundation you have will affect the cost of your house.

There are three types of foundations: slab, crawl space, and basements. Slab foundations are the most common and least expensive. Crawl space foundations are less common and more expensive. Basements are the least common and most expensive.

The cost of your foundation will depend on the size and type of foundation you have.

5. Concrete Reinforced cement concrete

Concrete in foundations, grade slabs, plinth beams floor beams, floor beams, and lintel beams are all included in the RCC quantities. This includes concrete on the balcony. There is no need to subtract the concrete's reinforcement volume from the concrete total. The reinforcement quantity can be taken as an item.

It is best to calculate shuttering of formwork separately. In the item description, it is important to describe whether reinforcement or shuttering has been included. It is measured in cubic meters.

6. Steel Work

The quantity includes binding in position, bending, and is measured in quintals. The binding wire does not require a separate payment. The percentage volume of reinforced concrete is used to calculate the amount of steel. For practical purposes, reinforcement can be calculated using the bar bending schedule. This is done after measuring the bars before concreting.

7. Shuttering (Formwork).

Formwork costs approximately 30% more than cement concrete. It is measured in square meters and multiplied by the length and breadth. It is the concrete surface with concrete or other materials that require formwork. The area of the concrete members that have been built up is generally taken into account.

8. Masonry work

Calculating the volume of brickwork involves multiplying its length, width, and height. Cubic meters is the unit. It makes it easy to break down masonry work into:

  • Foundation: Because there are no openings from the wall to the plinth, the volume doesn't need to be deduced.
  • Superstructure wall: First, the volume of brickwork must be calculated as if there are no openings. Standard deductions are made for opening volumes, lintel volumes, etc., after calculating brickwork volume. These deductions are as per the building standards.

In the estimation of building costs, the following items are included in masonry work:

1. Damp-Proof Course (DPC).

It is a mixture of cement concrete 1:2:4 and a water-proofing material. This layer is placed between the plinth and superstructure walls to stop water seepage from the ground via capillary action. It is measured in square meters.

2. Plain Cement Concrete (PCC) Works

This will allow you to determine the amount of PCC needed for foundation, trenches, and grade slabs. It is necessary to determine the quantity of slope required for foundations. Cubic meters is the unit.

3. Rough carpentry, Carpentry, and Trim Work

Rough carpentry is the frame or skeleton of your house. This includes the studs, joists, and rafters. Carpentry and trim work are the finishes that make your house look complete. This includes doors, windows, moldings, and cabinets.

9. Plastering

This is the measurement of the wall's surface before plastering. This calculates the required deduction for window and door opening. The area between walls is used to measure the plastering quantity. Ceiling plastering also includes the soffits of stairs. Observe these points regarding opening deductions:

  • No deductions or additions shall be made for openings less than 0.5 square meters.
  • If the opening is greater than 0.5m in size but less than 3m in height and both walls face the same plaster, then the deduction must be done on one side.
  • Each face of wall plastering shall be deducted for openings exceeding 3m2.

10. Pipeline Work

A Pipeline system is one of the most important components of a home. It is responsible for collecting and distributing water to the various rooms in your house. The cost of a Pipeline system can vary depending on the size and complexity of your home. Generally, Pipeline systems are made up of four main parts:

  • The pump: This is responsible for moving water from the source (usually a well or city water supply) to the rest of the system.
  • The pipes: These carry water from the pump to the different rooms in your house.
  • The fittings: These are used to connect the pipes and to the different appliances in your house.
  • The drains: These remove wastewater from your home and discharge it into a septic system or sewer.

11. Painting

This quantity includes the quantities required to apply 2-3 coats of whitewash, color wash, or emulsion paint. The area is used to calculate the painting quantity, just like plastering.

  •  Texturizing Painting or Stucco Roll-Out Batching System: A texturizing painting or stucco roll-out batching system is an automated system that can be used to apply a variety of textures to a surface. This type of system is typically used in commercial and industrial applications, but can also be used in residential settings. The cost of a texturizing painting or stucco roll-out batching system will vary based on the size of the unit, the number of textures that it can apply, and the complexity of the controls.
  •  Interior and Exterior Paints: Interior and  Exterior Paints are an important part of any house painting project. A wide variety of interior paints and finishes are available on the market, ranging from budget-friendly options to high-end designer products. It's important to choose the right paint and finish for your project to achieve the desired look and feel.
  • In general, Interior Paints can be divided into two main categories: Water-based and oil-based: Water-based paints are typically easier to work with and clean up, while oil-based paints provide a more durable finish. Once you've decided on the type of paint you'll be using, it's time to select a color or colors. When choosing paint colors, it's important to keep in mind the overall tone you want to create in your space.

 

12. Flooring and Tiling

This item is divided into two sections:

  • The ground floor flooring: This is the measurement of the amount of rubble soling below the foundations, floors, and pavements. This quantity can be either thick lime concrete or cement concrete with over-soling. Next, the top portion of the flooring is calculated. The top flooring can be of different types and embedded in cement mortar. These items will all contribute to the flooring of the ground floor.
  • Flooring of top floors: This is the area between the walls that should be flooring.

13. Woodwork for Doors & Windows

This item is divided into two sections:

  • Door and window frames: The quantity of the door and window frames can be calculated by multiplying their total length and their cross-section. Because there is no bottom sill, the total length of the door and window frame would be twice the height and one-half the width. It would be two vertical lengths and two widths. It is measured in cubic meters.
  • Door and window shutters: The quantity of the door or window shutters can easily be calculated by multiplying the width by the height and writing the thickness in the description. Double shutters are not allowed to overlap in the middle. Other fittings are typically paid separately and sold as separate items. It is measured in square meters.

In the building cost estimation, all these items should be considered. Considering all these factors, great precision is required in calculating them.
