To understand the difference between tender documents and contract documents, first we have to understand what these documents contain.
Tender Documents:
A tender is an offer in writing to contractors to execute the some specified works or to supply specified materials within a fixed time frame and as per conditions of contract and agreement between the contractor and the owner or the department or the party.
The tender documents contains the bill of quantities (BOQ), specifications of the works to be carried out, time frame for the completion of the work, conditions of the contract and plans and drawings. These documents are provided to the contractor on the payment of certain fees. The contractor who quotes the lowest rates for the overall works are offer the contract to execute the work.
Contract Documents:
Contract documents are the agreement between the owner or the party or the department and the contractor to execute the works as specified in the tender documents as per conditions of contract on the rates quoted by the contractor.
The difference between Tender and Contract Documents:
The difference here to be noted is that tender documents are offered to as many contractors as possible to get the lowest quotes for the work specified, while the contract documents are signed only with the contractor with lowest tender or rates.
While the tender documents contains the conditions of contract and all the details for the specified work, there is not much difference between the two in terms of contents. But tender documents can not be submitted as Letter of Acceptance (LOA) as these are two different types of documents. While a tender document can not bind the contractor to do the work, a contract document binds the contractor to complete the work as per the agreement.
Simple Example to understand the difference between tender and contract documents:
When you are selected for a job in a company you are offered offer letter to join the company. But getting selected in a company does not mean that you join the same company, you may have other offer letters as well. But when you sign the letter of acceptance (LOA) for the job, you are bound to join the company. So, here offer letter from the company is a tender document and LOA is the contract document.

Declination:
I am providing more additional information about the declination, have a look.
Here, I Attached a diagram of declination, through that we can clearly understand positive as well as negative declination.
- Whenever declination is towards the Eastwood direction then that declination is called positive declination.
- When a declination is going towards west word direction then it is called negative declination.
True bearing is the sum of magnetic bearing plus declination.
Thank you.

Hi, sunlight is the best source of light and energy. So to use effectively, the placing of windows and other openings and reflective surfaces matters a lot.
As a civil engineer, it’s our aim to maximize the comfort of the user and reduce the energy consumption for saving electricity.
The design of the building should be like this the rays of sunlight it will be scattered from the wall and reflect and cover a maximum area of the house. There will be no direct sunlight on polar sites of the walls that are north facing and south-facing. Providing large Windows is a good option to maximize the use of natural sources of light.
In the present scenario, translucent concrete is been used as concrete which transfers the light in various commercial buildings to reduce the use of artificial electricity. This is a great gift from nanotechnology.
the position of lights inside the room must be at the middle of the wall and not at the corners so that lights spread 180 degrees.
