New construction work often has a problem where the developer who did the construction does not offer consultancy or interior design, forcing the owner to resort to a new firm. The whole thing is time-consuming, troublesome, and in some cases expensive. To avoid this problem, the developer should choose an agency that provides all kinds of facilities in construction, consultancy, or interior design.
Does fast construction offer a way out of conventional problems? The first thing to keep in mind when constructing a new building these days is to meet the needs of investors and developers, design teams need to design the building in a way that helps the contractor to develop fast and efficient construction strategies to make the project profitable. These needs can be met through fast construction. Fast construction has become popular in our country with time. Although working with this method is very challenging and not completely risk-free, this construction method has several advantages.
Affordable
There is no room for overspending in this method as the budget is fixed before the work starts. Rather, it is possible for the owner to invest in other sectors while keeping an eye on the budget during the work. For example, in the case of health-related facilities, the owner can reduce the construction budget and instead spend on more modern medical equipment. Because of the short planning time, both the owner and the contractor can calculate what the costs will be, so they can be prepared in advance. In fast construction, you can be freed from the two situations of not collecting money in the middle or overspending of the budget. It is most cost-effective to rely on an organization that can undertake the task of completing the construction work quickly while maintaining quality standards. Normally there is a tendency to change the design or other details in the middle of the construction work, this is not the case during fast construction. Rather, in this case, all the design and planning work is fixed at the very beginning, so that there is no need to make any new changes in the middle of the work.
Profitable
The biggest advantage of fast construction system is that the commercial work can be started quickly after the construction of the building is completed. It is natural that the faster the ability to reach the market or the customer society can be achieved, the faster the organization will see the business profit. For example, in the case of telecommunication or information technology providers, it may be the case that reaching customers with services before competitors are ready. Again, in the health sector, it may be to provide the latest equipment or to acquire the ability to provide quick patient care. First of all, they need to complete the construction of the building. That’s why if the construction work can be completed as soon as possible, then it is possible for the business to enter the market quickly.
Cost Savings
Due to fast construction, incidental costs naturally come down due to faster completion of building work. Although slightly risky, fast tracking is the most effective way to reduce construction time. This method accomplishes work by starting tasks that need to be done sequentially at the same time and maintaining consistency between them. It is the responsibility of the construction manager to keep the cost figures in line with the progress of the design work.
An experienced team with good communication skills basically keeps the budget within reach. Firms experienced in fast construction provide solutions to all problems under one roof. In other words, they can easily take care of all matters as they have skilled manpower to undertake consultancy and interior designing along with building construction. And due to working together, the cost comes down a bit. Due to these reasons, fast construction is becoming popular among industrial and commercial organizations to get the best construction solution quickly within a limited budget.
The speed of economic development of Bangladesh is increasing in keeping with the rest of the world. New business ventures and investments are constantly coming to the market, experienced entrepreneurs are also expanding their operations. All in all, Bangladesh is currently passing through the most important period in its history of economic development. The need for private offices for businesses as a base for large-scale new ventures and investments cannot be overemphasized.
However, it is a very difficult decision for everyone to build their own building or move to a new office or rebuild an old office in terms of time and funding. If the construction of each building is time-consuming and expensive at the same time, then large business companies or groups have to face thousands of problems. In today’s era, fast construction is the most modern solution to the various obstacles faced by the owner in constructing or renovating an industrial or commercial building. Before talking about that, let’s take a look at what are the most common problems in the construction work of our country.
Budget
Contingency is a very common occurrence during construction work. Most of the time the cost of new construction or renovation exceeds the predetermined budget. And sometimes the owner is not satisfied with the finished work, they think that the work is not good in proportion to the cost! Even after having the estimated cost calculation given by the contractor, the market price of the materials, all the cost calculations, when it is seen that the cost is more than the initial calculation over time or the money cannot be collected in the middle – then both the owner-contractor parties are in trouble. And the easiest way to avoid this trouble is to complete the construction work quickly while maintaining the quality.
Contractor
There are also situations where the budget is not a problem, the owner is able to afford all the construction costs, but the contractor is the ghost. Maybe they are not punctual, maybe their behavior is very unprofessional. Whatever the reason, ultimately it is the owner who bears the brunt of the mistake. Especially if you are short on time, it is better to research the company you are hiring in advance rather than run the risk of screwing up midway.
Time
Lack of time is always a major problem in construction. Usually, during the long period of construction, the office has to be relocated to a temporary location, thereby halting much needed work. Lack of manpower, inefficiency of the contractor, adverse weather conditions or any accidents during the work etc. may take more time than the scheduled construction time. Therefore, if the competent contractor can guarantee the completion of the entire work in a very short time, is it not a better decision to give them the responsibility?
Quality of materials
If there is any problem with the quality of the materials used in the construction, it is noticed by the owner months or even years after the completion of the work. After realizing that the project has been done with substandard materials, there is really nothing to do but head over heels. Therefore, before starting the work, all kinds of inquiries should be made about the quality of the materials. And if those who are entrusted with the responsibility of construction, are fully aware of this, then that can be the best solution.
