Basic Factors to Consider When Cost Planning Your Building Project

The general premise I would wish to take emanates from the intriguing question, “If a man wants to build a house, does he not first sit down and estimate the cost?”

It is thus imperative that one needs to “sit down” and contemplate or wrap his mind around the entire building project to determine whether it is worth his while to embark on the journey of construction.

While undertaking Cost Planning for your building project, it is important to keep in mind that the final cost of the house will be affected by both Design Factors and Economic Factors.

Design Factors

The design factors like shape and size of the building, complexity of the design, circulation space of the building, the height and the structural design of the building will have a bearing on the final cost.

It is also worthwhile to note that the workmanship and quality of materials to be used as determined by the specifications will have an impact on the cost. Most persons wishing to build are surprised at how varying one item like the type of finishes can have a high impact on their construction budget. Every building material has a substitute which could be cheaper or more expensive but plays the same function.

For example, among Roof Covers, we have corrugated roofing sheets(Mabati) , Makuti and thatched Grass, Box Profile Sheets, Stone Coated Tiles, Clay Tiles and Shingles. All play the same function but are priced differently. They also require different levels of expertise which has a bearing on the final cost of roofing.

The one you pick will have its own specific cost implications like Timber Spacing, Initial Cost and Maintenance Costs. Read: Which is the Best Roofing Material?

Economic Factors

There are other hidden factors that will have an effect on the final cost of doing the building project. For instance, the interest on borrowed funds and price fluctuations caused by inflations or market forces can affect an initial cost plan of a project.

The source of the building materials, that is, whether available locally or imported will also affect the overall cost plan. There are some designs that may necessitate sourcing of skilled laborers and this would add to the overall cost. Building with machine cust stones is cheaper than building with Bush-Hammered Stones.

Political Factors

There are Political factors in terms of how stable a neighborhood is or the safety index of a neighborhood. One can readily tell that a high-end zoned neighborhood where the development is controlled could be cheaper in terms of security measures to be incorporated in the cost plan but relatively expensive since one has less free-play in the design variables.

Upon completion of the design and comprehension of all factors affecting the cost plan, the tasks, timings and costs are summarized in a Developers Budget or a Project Baseline Plan that will set out for you the roadmap towards home ownership. The Developers Budget will have a breakdown of the following items:

  • Construction Cost
  • Cost of Land Purchase
  • Cost of Finance
  • Professional Fees
  • Legal Fees
  • Preliminary Costs
  • Management Costs
  • Marketing Costs (If Development is for Sale)
  • Anticipated ROI (Return on Investment)

The Construction Project Workflow will also be reflective of all the factors that will affect the Building/Infrastructure Project from Inception to Completion.

One truly needs to be meek and confident enough to “sit down” when it comes to making a decision to build a House!

I trust that in your meditation to build, you shall consider the aforementioned lest people pass by your incomplete Building Project quoting Scripture:

“For which of you, intending to build a tower, sitteth not down first, and counteth the cost, whether he has sufficient to finish it?

Lest haply, after he hath laid the foundation, and is not able to finish it, all that behold it begin to mock him,

Saying, This man began to build, and was not able to finish.”- Jesus Christ, Luke 14:28

10 Practical Ideas To Lower Building Cost Without Cutting Corners

httpss://twitter.com/UjenziBora/status/820971727849160705

It is always better to keep the building project within your financial expectations without compromising its integrity. This article is not about building a “cheap building” but Management of Costs irrespective of the size or budget of the project.

The beauty of managing costs is that resources are not wasted and whatever is left can be used on other aspects of the building like landscaping or enhanced security.

1.0 “Manage the project within a Construction Process”

In building a house, there is a messy process and there is the right process of doing things. The easiest way to have cost-overruns is to be dis-orderly.
Management creates order in the building process. The right process helps one to:

Control the Risks.
Control the Design.
Control the Labour Costs.
Control the Overheads.

You will have an upper hand if you have the benefit of foresight, planning and management. You require a program of works and a Method Statement for the Project. This will save you time and money.  Don’t just build as if you are cooking “fufu”.

Have a plan and a process in place before starting the building project.

2.0 “Optimize your building site”

You need to plan the house with a clear view of site conditions. Don’t “copy paste” designs from one site to another even if the user needs are the same.
Simply, cut your coat according to your cloth:

i)If you don’t have much level ground, design a house with a small footprint (ground cover).

ii)If your site is sloped, consider doing a basement instead of spending money on cut and fill.

3.0 “Story buildings are relatively cheaper”

Suppose you have a 1500 square meter house all spread out on the ground and a three story house with each floor covering 500 square meter , which one gives you more value for money?

i) Roof Cover- In our example, for the same amount of floor area you spend less on roof covering.

ii)Foundation Costs – In our example, for the same amount of floor area you spend less of foundation costs and ground preparation.

iii)Savings on land are realized by building vertically.

Clearly, stacking saves one money when building. However, this option is limited by the zoning laws and regulations of the City Council or County/Municipal Council.

4.0 “Simplify the Design”

Leornado Da Vinci is quoted as saying, “simplicity is the ultimate form of sophistication.”

Yes! Take more time in the design stage of the construction.  Be realistic and practical when drafting the Design Brief. A more complex design will cost more.

A complex roof-line with excess ridges and valleys will add to the time and cost of construction.

Let form follow function. Think about the maintenance cost of every material forming the fabric of the house.

Remember, for every building fitting or material, there is an alternative maintenance free material.  Cheap is expensive, therefore Buy Quality to minimize cost-in-use.

To reduce on the building cost, you can avoid curved rooms, curved walling and overly sophisticated designs without compromising on the aesthetics.

5.0 “Consider Open Floor Plans”

You do not necessarily need a solid wall separating the kitchen, the dining and the lounge. You can partition using half a wall. You can also opt to have an open plan between the three spaces (Lounge, Dining and Kitchen). Do a comparative cost-analysis of various options including making the lounge sunken to “define it.”

6.0 “Minimize Administrative Costs”

Have an on-site project office, a clerk of works and a store keeper to handle records as to building materials. Record management will help in minimizing waste, theft and anticipating periods for re-ordering materials or labour.

7.0 “Manage the procurement Process”

A crafty contractor may maximize profits by under-quoting on labour but offloading his profit ambition on procurement of materials.
Where do you source the materials and fittings?
Is it done competitively?
What are the alternatives?
You can save much by pre-ordering fittings and fixtures.
Have you considered imports for bulk supplies?
Consider that you can obtain a superior fitting.In case of large capital investments, one can have considerable quantity discounts by buying in bulk from the source, eliminating middlemen.

8.0 “Look at the House As An Extension of Yourself”

The best way to do this is to outline your role and key functions.  Consider multi-use spaces and utilizing and creating space that would ordinarily not be in the normal houses. You will more enthusiastic about your house only if it reflects your aspirations. It is not ab-normal to have a house without a typical lounge or bedroom. Form follows function. Most people incur unnecessary costs building a house “like that of their neighbor.” For example, if you don’t like visitors, there is no point building a guest house if you are straining your budget! Let that money go into a spacious lounge or more elegant finishes.

9.0 “Do not Ignore Insurance”

The only way to mitigate certain risks is by Insurance of the works, workers and materials. Obtain a Contractor All Risk(CAR) Policy for the duration of works. Construction insurance provides safeguards for you as an employer against your construction workers being injured on site. Construction insurance does not exempt you from maintaining a safe workplace.

10.0 “Have a Contingency Plan”

This is money set aside for “unforeseen circumstances” which may eventually sink the building project if not taken care of. Also, have in place rules t spend the contingency fund. They include things like:

i) Inclement weather.

ii) Foundation issues

iii) Cost overruns from extended preliminaries, making changes, and encountering unforeseen design problems.

iv) Inflation and adverse Market conditions
