What is a preliminary estimate and how it helps?
A preliminary estimate or conceptual estimate is used to forecast the project cost to analyze the economic feasibility of the construction project prior to the development of detailed drawing plans. It helps contractors, real estate developers, home builders, and owners in making decisions for allocating funds, setting the preliminary budget and comparing initial design alternatives.
As preliminary cost estimates are carried out at the beginning of the project before the actual design and construction, therefore they are mainly based on historical data of the projects adjusted to the time, location, size, and prepared using engineering concepts.
There are several types of preliminary cost estimates that are employed at various stages in the lifecycle of the project. The accuracy of these estimates depends on the extent of the information provided by the client.
Rough Order Magnitude Estimate
The first attempt to estimate in the project’s lifecycle is regarded as a rough order magnitude estimate or ROM. It is employed to analyze the feasibility of the project that contributes to the project’s selection and allocation. It has accuracy in the range of -50% to +50%.
Ballpark estimate is developed by the contractors to define the scope of work to their clients, so that owners can make decisions according to their budget. It is evaluated on the basis of preliminary drawings and specifications, and its accuracy lies within 20% of the actual cost.
The budget estimate is prepared using past projects’ data and plans when the project comes into its planning stage. It defines the costs associated with the major components of the projects in each line description including materials and labor costs. Its accuracy lies in the range of -10% to +25% of the actual cost.
A definitive estimate is also known as a digital cost estimate contains a detailed itemized list of components involved in the project. It is prepared by using thoroughly developed project plans and has an accuracy of -5% to +15%.
How can our preliminary estimate benefit you?
Our estimates can help you in evaluating the initial cost to support in:
- Managing the budget and getting loans
- Setting the project cost limit for Architects and designers
- Getting the idea of probable amount and cost of material and labor.
- Planning the next phase.
- Allocating and negotiating with contractors and subcontractors.
How can you quote a preliminary estimate to your prospective clients?
Our preliminary cost estimates are based on the floor area which makes it easy for your clients and architects to understand and interpret the information.
Our bill of material comprises of:
- The total area (square foot or square meter) of the complete project
- Linear measurement (foot or meter) of each structure like walls etc.
- Area of each unit i.e. rooms, floors, etc.
What do you get in our preliminary estimate?
The estimate consists of the breakdown of quantities, and the following divisions are considered:
- Substructures (footings, foundations, etc.)
- Superstructures ( brickwork, walls, sidings, roofs, staircase, floors, doors, windows)
- External/Internal finishes (flooring, drywall, painting, etc.)
- Mechanical (HVAC systems, ductwork, etc.)
- Plumbing (pipes, drains, fixtures, etc.)
- Electrical (cable, conduit, lighting, etc.)
- Man Hours
- Project Schedule
How do we prepare a preliminary estimate?
- First, our estimators study and evaluate the information to analyze the scope of the project and produce an estimating plan.
- Then, the data of similar past projects is collected.
- The adjustments are applied with respect to time, location, and size. A contingency is also applied.
- All the specifications, adjustments, assumptions, are mentioned in detail.
What factors contribute towards the right preliminary estimates?
While performing a bill of material based on previous projects’ data, we make assumptions and adjustments with respect to time, location, type, and size of the project.
- We modify the project cost to the time of the start of construction because these estimates are calculated two or more years in advance to construction therefore cost must be identified with respect to the future. It is adjusted using a time index which includes relative inflation or deflation with respect to time due to factors like labor rates, material costs, interest rates, etc.
- The anticipated project cost is evaluated with respect to location as the material, labor rates vary in different parts of the country. For this purpose, we employ our location index to national average cost to adjust the bill of material for a particular region or closest capital city.
- Project cost is also dependent on the type and size of the project. Here, we apply the size factor which relates the proposed building area to the typical building area.
- The quality of the basic material required in the construction is also considered eg brick veneer, CMU, framed, etc)
