Hi Emmyvin,
In a designer look with private swimming pools, landscaped surrounding greens and terraces, double-height patios, private elevators, and sun decks if the project is undertaken by the builders of high repute. A bungalow expresses a bit traditional kind of living space while luxury villas are being given a series of high-end modern facilities. Indian bungalows are different from villas and are mostly the properties coming to an heir from his ancestors. While villas are built in pre-demarcated plots; bungalows are completely detached houses that are built on an independent land. The owner bears the responsibility to develop the property in case of bungalow; while a villa can be called a representation of modern community living. In the present times, villas are given the garb of gated communities to offer enhanced security to the dwellers.

Hi Nigel,
Welcome to theconstructor.org . I understand your requirements.
The most economical method of compacting is uses of bamboos and root fibres in the soil which makes it steep compact and highly tensile resistant.

Hi,
The profit and loss account and cash flow statement are introductory presentations of the company’s activities. And they are straightforward to understand.
a) Profit and loss statement: All you need to remember is that whatever income is received by the company is written on credit (right) side. Whatever expense is incurred by the company is written on the debit (left) side of the statement. The key figures on the right side to focus are sales revenue and any other income the organization has earned during that period. It is essential to observe the primary sources of payment for the company. Naturally, on a bank’s P&L account, it would be mainly interest received from loans and advances, and investments. For a manufacturing organization, it should be sales proceeds from its products and other ancillary services. Similarly, the debit (left) side shows the expenses/losses incurred by the organization during that period. You may focus on a particular kind of payments like personnel cost, cost of materials, advertising and marketing expenditure, etc.
b) Cashflow statement is slightly more technical in its composition than profit and loss account. It consists of mainly 3 parts: 1) Operating activities (core business activities), 2) Investing activities representing investments made by the company, and 3) Financing activities representing the capital structure of the company. Consider this. Walmart sells wares on its online portal. But it needs money to run its operations. So, say it raises $ 1 million from some source. Now, it invests $ 0.5 million from the amount in building the online infrastructure and logistics network and uses $ 0.5 million in the routine operations of the firm. > 1 million raised will be a part of financing activities in CFS. > o.5 million used in advertisement will be a part of investing activities in CFS. > 0.5 million used in daily operations will be a part of operating activities in CFS.

Hi,
In the construction of metros, the contract must be utilised the the the Indian Standard System of units and the court’s values in the empirical units were not be used unless the engineer is given consent. while all the standard course and technical specifications are practised must be of the latest edition which included the applicable official amendments. The contractor makes a well of all the relevant Indian Standard course and Indian road Congress codes which are applied. Nowadays priority order is IRS, IRC IS, BS, DIN.

Hi,
Generally, Steel reinforcement is used for the construction of bridges and bridge decks, where reinforcement is acting as a tensile load carrying material and used to resist the tensile stress. Generally due to thermal stresses expansion may occur in structures which leads to crack if expansion joint is not provided. in this way expansion joint is designed as a safe way to observe the heat-induced expansion and contraction of structures. In traditional systems, the expansion is of rubber-based and nowadays it is highly used in cement concrete road because it can expand when heat increase. Following are the two types of expansion joints used nowadays
