What is supplementary estimation?

Supplementary estimates set out proposals for amending the departmental spending the House has previously authorised via the main estimates. Supplementary estimates are normally presented in February each year and approved in March, before the main estimates for the following year are published.

What is a revised estimate?

Revised Estimates: Revised Estimates are mid-year review of possible expenditure, taking into account the rest of expenditure, New Services and New instrument of Services etc.

What is revised estimate why it is prepared?

Abstract of Estimate. Revised Estimate. It is prepared when original sanctioned estimate is likely to exceed more than 5\% due to changes in quantity of material or rates. Supplementary Estimate. It is the fresh detailed estimate of the additional works in addition to the original estimate.

What are the difference between preliminary estimates detailed estimates?

Preliminary estimates: These are typically used very early in the process before the details are complete. Detailed estimates: This type of estimate provides a deep dive into the details and costs of a project. Project management estimates: Project managers can pick from four types of estimates for their projects.

What is supplementary estimate in civil engineering?

Supplementary Estimate : During the execution of project, structural modification are required or addition work is added for construction. The estimate for additional work is called supplementary estimate. Supplementary estimate is also required to be prepared when some of the items are overlooked.

What are the different types of estimates?

Preliminary Cost Estimate.

Plinth Area Cost Estimate.

Cube Rate Cost Estimate.

Approximate Quantity Method Cost Estimate.

Detailed Cost Estimate.

Revised Cost Estimate.

Supplementary Cost Estimate.

Annual Repair Cost Estimate.

What do you mean by supplementary estimate explain the circumstances under which such estimates are prepared?

11.a. Circumstances under which the following estimates are prepared: Supplementary Estimate: 1. When there are few changes in work or any additional or further development of the work is required. 2.

What are the different types of estimates how they differ from each other?

Approximate Quantity Method Cost Estimate. Detailed Cost Estimate. Revised Cost Estimate. Supplementary Cost Estimate.

What are the two types of estimates?

There are two types of estimates: point and interval. A point estimate is a value of a sample statistic that is used as a single estimate of a population parameter.

What is a supplementary estimate in civil engineering?

So, supplementary estimate is due to material deviation of a structural nature from the design originally approved. No comparative abstract form is required. This is an estimate for additional works only. The abstract shows the original estimate and total amount of the sanction required including supplementary amount.

When is a revised estimate required?

Revised estimate is required due to change of rate or quantity of materials so no additions or revision of drawings is necessary. This is required due to supplementary works which are fairly independent of the work at first sanctioned.

What are the different types of estimates in construction?

Thus the various types of estimates prepared according to their requirements may be classified as follows: Plinth Area Estimate. Annual Repair (A.R) or Annual Maintenance (A.M.) Estimate Of the above estimates, the first four belong to approximate estimates and the remaining five are detailed estimates.

Why is it necessary to prepare an approximate estimate?

Before a detailed estimate of the proposed work is to be taken up, it is necessary to prepare its approximate estimate. An approximate estimate gives the approximate cost of the work and is prepared on the basis of cost of the similar works carried out in the past.
