What is difference between variation and deviation?

What is difference between variation and deviation?

Variation is a magnetic interference common to all vessels. Deviation is a magnetic interference unique to the vessel itself.

What is cost escalation in construction?

An escalation clause is a provision in a contract that calls for adjustments in fees, wages, or other payments to account for fluctuations in the costs of raw materials or labor. This clause shifts the burdens for increasing materials and labor costs from the contractor to the client.

What is a variation on a construction project?

A variation (sometimes referred to as a change) is an alteration to the scope of work originally specified in the contract, whether by way of an addition, omission, or substitution to the works, or through a change to the manner in which the works are to be carried out.

What is deviation in civil engineering?

Deviation in context of trenchless construction can be defined as the difference between the planned bore path and the actual bore hole. Deviation can occur due to problems with the drill, operator error or due to unforeseen sub-surface conditions.

Is standard deviation better than variance?

They each have different purposes. The SD is usually more useful to describe the variability of the data while the variance is usually much more useful mathematically. For example, the sum of uncorrelated distributions (random variables) also has a variance that is the sum of the variances of those distributions.

What is project escalation?

Escalation in project management is an anticipated rise in uncommitted costs of resources (labor, material, equipment) over time, due to reduced purchasing power of money. The Project Manager is the person responsible for ensuring that the project team members meet milestones, and complete the project.

What is the difference between inflation and escalation?

Inflation is a general term for price adjustments driven primarily by changes in the money supply. Escalation includes price adjustments due to any factor, including technology and supply-demand imbalances.

What are types of variation?

Variations are classified either as continuous, or quantitative (smoothly grading between two extremes, with the majority of individuals at the centre, as height varies in human populations); or as discontinuous, or qualitative (composed of well-defined classes, as blood groups vary in humans).

What causes variations in construction?

The result from revealed four most significant causes variation orders which are: ‘Change of scope by owner’, ‘Substitution of materials by owner’, ‘Changes of specification by owner’ and ‘Changes of design by consultant’. Meanwhile the effects of the variation orders are time and cost overrun.

What is coefficient of variation in concrete?

The coefficient of variation is typically used when Page 5 comparing the dispersion of strength test results of records with average compressive strengths more than about 7 MPa different. The average within-test range is used for estimating the within-test standard deviation.

How do you calculate deviation in construction?

Most common example is deviation in FAR (Floor Area Ratio) / FSI (Floor Space Index). FAR is defined as Total Covered Area in the building on all floors divided by Gross Area of the plot.

What is the difference between escalation and deviation in a contract?

And for some contracts, only fuel escalation is considered and based on the actual price change, and it is also possible to have this escalation based on consumption of fuel not for the value of work done. Deviation is something away from the Standard, Variation is something additional or change in the scope or an item of work.

What is variation in construction projects?

In construction projects the term ‘Variation’ means any change to the original contract. These variations can be in a way of addition or omission to the original scope of work. There are many causes for variations in construction projects.

What is escalation in construction projects?

Since Construction Projects span over a period of time and this business involves resources of fluctuating prices, there has to be always a provision for Escalation (be it is paid with the interim bills or quarterly or the risk is considered).

What is the difference between deviation and variation?

Deviation is something away from the Standard, Variation is something additional or change in the scope or an item of work. But however sometimes, this variation and deviation are used synonymously which is not 100\% correct.
