The construction of a house is one of the major investments that one makes in his/her life financially. In an active, competitive real estate market such as that of Bangalore, any rupee of cost on any building should be optimized. One of the most effective tools to control costs from the outset is a precise building design 2D plan. Although photorealistic 3D renderings and walkthroughs might channel homeowners into a false sense of security following the plans of the construction, the detailed 2D drawings made by engineers and architects are the real behind-the-scenes heroes of every successful construction project. These 2D architectural plans form the backbone of the project, guiding not just the layout but the budgeting, estimation, legal compliance, and coordination during construction. Most people think that 2D plans are planar representations of a building. But a 2D drawing that is well drawn is a technical roadmap. It entails the wall alignment, where the column will be positioned, beam positioning, room dimensions, utility, schedules of doors and windows, and even furniture layouts. When matched with both structural soundness and local codes, these specifications result in enormous cost savings throughout the lifetime of the construction process. In this blog, we delve into five key reasons why a comprehensive building design 2D plan can help you avoid overruns, save on material waste, and ensure a smoother construction journey.
The material estimation is one of the most on time influences of a 2D plan on your construction cost. Each construction site presents the need to buy and control the use of a vast assortment of materials such as cement, steel, bricks or blocks, sand, gravel, tiles, plumbing pipes, electrical wires, and fittings, among others. An architectural design in 2D will help present the correct dimensions of all spaces inside the building, which is used by engineers and quantity surveyors to ascertain the amount of each material to be utilized.
Wastage is minimized when estimating the materials to be used is carried out using real measurements of the building plan instead of crude estimates. As an example, it would be like playing a guessing game when it comes to ordering bricks to make a boundary or calculating steel to make a slab without a plan. Over-ordering results in the storage problem, risk of theft, and spoilage, and under-ordering results in work stoppage and delays. With the unpredictable market conditions, such as in Bangalore, where the price of materials such as steel and cement fluctuates week by week, a good estimate will guide you to buy in bulk at a convenient time and lock in the costs to avoid falling into the trap of inflationary losses. A building design 2D plan makes all of this possible by serving as the reference document for procurement.
Any modification on site during the construction process is costly in terms of additional cost of material, remodeling, or slowing down the schedule. These alterations tend to come up when the site team is facing some ambiguities in the design, or when some structural elements were not planned in detail before. One of the typical examples is moving a stairway which has been poorly located and site it later out of line with the beams or changing a bathroom layout because the plumbing lines were not indicated in the drawing.
With a clear 2D architectural plan at hand, these problems are highly reduced. All the structural elements occupy an already set position, which is not only determined on a decorative basis but also a load-bearing basis. The walls belong to a pattern of the beam, the columns are in a grid, and the doors and windows are not only functional but also symmetrically located. This accuracy prevents the on-site alterations where the correction of errors is hard and costly. The drawings give confidence to the workers to follow the course, and the site engineers are in a position to check progress against the agreed layouts. In due absence of such clarity, contractors have to operate on the spur of the moment, and their decisions are well-known judgment errors.
In our experience at Arun Nirmaan, clients who finalized their building design 2D plan well in advance faced far fewer structural revisions during construction, and that directly translated to savings of up to 10–15 percent in total construction cost. Rework not only costs money, but it also increases project time, thus the project cost itself becomes an overhead, as the rent or EMI has to be paid.
Bangalore construction comes under the Zonal authorities of Bangalore, BBMP, BDA, and Panchayats, according to the zone and locality of the plot. To obtain the approval of a project, detailed plans as per the stipulated rules need to be submitted, which include setback size, road access, limitation of maximum permissible floor area ratio (FAR), and height limit. These approvals can only be obtained by presenting a well-drafted 2D architectural plan.
A violation of regulations may cause your construction to be stopped or even partly demolished. The fine charges, legal advice, and redesigning of those problems can cost lakhs of rupees. In real estate, time is money, too. Each week that you fall behind approving it adds to your holding cost and possibly to the escalation of labor and material prices.
A professionally prepared building design 2D plan aligns with municipal CAD templates and includes annotations required by authorities. Our experts do it all at Arun Nirmaan, i.e., we make sure that all our plans in 2D are made keeping the local norms in mind and are ready to submit. This assists our clients in achieving approvals in a shorter period and beginning construction without any ambiguity in the law. The correct 2D documentation also facilitates when someone wants a loan or insurance, since most banks will not lend the money without the proper documentation that has already been approved.
A housing construction project is a project where there is cooperation between different groups, such as the architects, structural engineers, civil contractors, electrical consultants, plumbers, and interior designers. Every team knows the other team, and they work on a distinct part of the project, which should conform to the same space limitation. Without a unifying building design 2D plan, these teams end up working in silos, often leading to overlaps, conflicts, and repeated work.
As an example, an electrical conduit may be installed on the site of a water pipe, or a false ceiling program may contravene the height of an overhead beam. These can be a problem because in case they have not been layered as per the architectural plan in the service drawings. A full 2D architectural plan will show all the relevant markings of the electric points, water inlets and outlets, drainage slopes, switchboard, light fixtures, and ducts of ventilation. Coordination is achieved when all teams are talking about the same plan.
This not only eliminates rework but also accelerates the project. The guesswork and waiting for decisions are no longer waiting with the contractors, and the elements within his or her team are sure to progress their work on tasks that might otherwise need several concurrences or will be redesigned. The saving of time here is magnanimous, particularly in high-traffic areas of the city where labor costs are exorbitant and where there is costly delay on the project or rental on the property.
Bangalore is one of the cities in which many homeowners construct houses on long-term strategies. They can build a ground floor first and then add another floor in a couple of years in the future, as the family increases or as finances improve. But when future addition is not planned in the foundation and structure, the price of expanding increases at a later point to an excessively tremendous amount. And it is more costly to tear down walls, to install new beams, or reinforce the foundation after the house is built, which is something that cannot be done unless one plans it ahead of time.
A carefully thought-out building design 2D plan considers future possibilities. It is possible to design the building structure grid and put columns in a manner that makes vertical development structurally viable and economically feasible. They are also able to allow future creation of shafts that can be used later in washing rooms or elevators, make staircases line up, a nd leave an opening for overhead tanks and the use of solar on the rooftops.
The importance of a precise building design 2D plan cannot be overstated when it comes to saving money during construction. It allows for accurate material planning, eliminates the risk of structural errors, ensures legal compliance, enables smooth collaboration between teams, and lays the groundwork for future modifications. In an environment where even minor missteps can cost lakhs, a comprehensive 2D architectural plan serves as both a safeguard and a strategy.
If you’re planning a new home in Bangalore, make your first investment in a professionally drafted 2D architectural plan. It’s the one place where spending a little more upfront can save you a lot more in the long run.
