1. Expenditure on site preparation The costs of site preparation, which include demolition, clearing and excavation, vary with the slope, location and the site\u2019s soil type. It is good that contractors include these costs to ensure the cost is bearable for home owners. The amount to be charged is calculated based on the amount of soil that should be excavated and transported off the site, plus the time and labour included. It is important to do your research so that you are not overcharged. 2. certification, Approval charges It is very common that, depending on where one stays, there will be a different approval fee charged for a project. You may choose to pay the approval fees to either a private building certifier or the local council. It is essential that the fee is included in the construction quote to avoid overspending. A lot of builders usually overlook this fee or are equally unaware forcing home owners to spend money that is beyond their budget. 3. Land fees Many buyers and developers often fail to consider the cost of land in its totality. This includes not only the cost of the parcel of land but amenities and deed transfer fees as well. It is important to know the prevailing cost of land in the area you are interested in to avoid being duped. A lot of buyers are spending too much for basic amenities within their surroundings without as much as proper interrogation or raising pertinent questions. 4. Security Before you start building, especially on new land where you do not know anyone, start by fencing your property. You do not want your construction materials stolen. You can also choose to hire some security for the same purpose. Make sure that the cost of fencing and security personnel is included in the quote. 5. Structural quotation Many builders will do a quotation based on the architectural plans. Most likely the floor slabs, the footings, the structural steel, and the timber will drive costs up. While the structural timber may be easy to quote, the steel is more of guesswork or based on estimations. So., it is important to consult experienced builders to be able to judge the approximate costs. 6. Interim requirements Usually these are temporary requirements on the site. Toilets, housing for security personnel and temporary fences are one of them. It is important to ensure that all thes needs are included in the quote. There is need for good inventory and listing of what is available on site before, during and after construction process to avert extra expenses. 7. Power connection During the process of building your home, you will need to connect your house to the grid. This is not a cheap affair and will definitely drive up your budget. Mind you; this is never included in many builders\u2019 quotes. Always consult Kenya Power and factor this cost into your construction quote. 8. Finishing touches needs Finishing is perhaps the most expensive part of any construction. Structure costs take about 30 per cent of the entire project while the rest goes to the aesthetics bit. The better quality the finishing, the more expensive it will be. If you fail to conduct due diligence, your contractor will balloon the finishing cost. Therefore, source around and find the best suppliers. 9. Insurance It is important for any home owner to ensure that his property and the workers are insured so as to curb cases like damage, injuries or even death. This is a cost most developers either ignore or are not absolutely aware of. Damage to property can include improper construction of structures, damage that happens during a renovation, and damage to temporary works erected on-site. 10. Water Water is an important component of any construction. Therefore, you must factor in the cost of water, especially if the area is resource-scarce. Cement concrete is the backbone of construction, and it requires lots of salt-free water to be produced. To avoid spending too much on water make sure that the cost is included in the quotation.
