Why construction costs vary – Part 2 (Different building companies and cost bases)

 

In our previous post we discussed the first reason why construction costs vary between projects, being different scopes and assumptions per project.

In this post we will be discussing the second reason why project costs vary per project.

 

Reason 2: Different building companies and cost bases.

 

Within construction, in particular residential construction, there are really three types of contractor and they should be viewed as providing effectively different services.

 

  1. Sole traders (1 - 3 partners)
  2. Small companies (3 - 10 team members) 
  3. Large companies (10 - 20+ team members)

 

Sole traders (1 - 3 partners)

These are informal individuals or groups of individuals who sometimes run projects and sometimes work for lead contractors. The lead(s) will usually run one or two projects at a time and often continue with a particular trade as this will not take up all his or her time.

Because of this more informal and low turnover approach these groups will often not be VAT registered or ask you to pay some team members directly to avoid going over the threshold.

This can mean a significant cost saving as VAT is usually 20%, they will also not be charging much of a margin, usually less than 10% on top of their team members work as their wages are mostly covered by their trade. But bear in mind that it means they may not take responsibility for the entire project. They will also not see management as their core function. They will have lower overheads which means a lower cost base, but as a result they will also struggle with complex or unique elements. So this type of contractor is best for low risk, low complexity projects and situations in which you’re happy to be more hands-on with the organisation.

Because the VAT threshold is only around £90,000. Any group specialising in projects over £10,000 will reach this threshold quickly and so you should approach with caution anyone in this group taking on projects of that size or above. They would have to be either very creative with their accounting or inexperienced. 

 

Small companies (3 - 10 team members) 

These are usually formed when a sole trader or group of traders decides to go one step further than informal ad hoc projects and form a limited company. Usually because the project sizes have become such that the financial risk is best kept in a limited company.

Usually at least one team member will have the sole function of ‘management’ and won’t do much site work but will instruct and arrange. This means their costs and any other overheads associated with more complex projects will need to be covered in a margin. Usually 20 - 30%.

They will need to be running 2 - 4 projects at a time to finance this and therefore are likely to have developed an increased marketing presence. They will be more comfortable with appropriate insurances and contracts and therefore lend an additional degree of security to their clients.

There are few drawbacks to this kind of contractor and indeed they are seen as the traditional ‘builder’. If you can find an organised and experienced contractor managing no more than 2 - 4 projects at a time, that’s the ideal for any project between £20,000 and £250,000.

 

Large companies (10 - 20+ team members)

Large companies still have an important role to play, naturally in projects which require a varied and sizable team. But these are usually commercial or development projects. So for the moment we’ll focus on their relevance to the residential sector.

There are some residential projects around £250,000 - £1m which can’t be handled by most contractors and therefore large businesses have to be created. However, sometimes these businesses will need to or want to take on smaller projects to keep their teams busy or for particular specialisations, for example lofts or listed buildings. 

These companies will inevitably have larger overheads, offices, vans, customer support etc. which can increase their margins to 30 - 50%. However, the level of construction risk with them is lower as they will be heavily insured and usually dealing with larger projects, however they can go spectacularly bankrupt so make sure to pay after rather than before work is complete. Indeed this general principle will serve you well with all contractors.

Why construction costs vary – Part 1 (Different Scopes and Assumptions)

BuildPartner is an estimation software that helps homeowners and professionals manage pricing for construction work. Specifically by enabling users to check benchmark prices, create detailed cost plans, and collect comparable quotes.

Our platform has been built using data from thousands of projects over many decades by a large group of architects, builders, and quantity surveyors but with a particular emphasis on residential work under £1m, which is particularly useful for homeowners. So today we’re going to share with you some insights which we’ve built up and how they can help you manage your renovation costs. We’ll cover first why construction costs vary and then what to do to mitigate it:

Why construction costs vary

 

Pricing for construction is often seen as an opaque process, easily subject to abuse, and indeed it is. But that doesn’t mean it’s actually as complicated or as abused as you might expect.

Many people on our team have run building companies and pricing companies and we can promise you, it’s extremely rare that anyone is actually trying to game the system or take advantage of you. In fact we are often shocked how regularly builders take financial hits for their clients.

However, that does not mean that prices are not variable. They can vary enormously. Which leads to uncertainty. It is fair to ask, if quotes can vary by 30-50%---as they do very regularly---how can they all be right!?

Well the answer to that is actually quite simple and we will explain it. The main cause of the variability is that they are simply quoting for different things. So we will explain a little bit more about what that means and what to do about it in three a three part series:

  1. Different scopes and assumptions
  2. Different building companies and cost bases
  3. Natural variability in prices

1. Different scopes and assumptions:

 

Renovating a house is not like buying a pair of shoes. It is more like designing them, you are literally building your product. This is both part of the joy and part of the complexity.

There are millions of different products and service providers and hundreds of millions of different combinations which you are putting together in your specific way and your specific location. Exciting as it is, this is the heart of the complexity, you cannot know how much something will cost until you know what you want. However, you cannot know what you want until you know how much it will cost.

We could go round and round like this but then we would never get anything done. So we have to work with assumptions, and therefore it’s very common, if not the norm, to collect quotes without all the details of the project being confirmed. This is one of the main causes of variability.

As a result of variations in scope we see a pre - quote variability of around 80 - 100%

This is largely due to specification alteration. At the beginning of a project the scope of the works you want to carry out and the specification of those works aren’t confirmed. Therefore any estimate or quote at this early stage will have a natural variability. You may want to do the loft extension another time or you may not get planning permission for the basement.

This means that the sooner you can confirm the exact scope and specification of your project the sooner you can reduce the uncertainty and variability of your project costs.

Of particular importance is that if you are aware of the scope of your work, you can more accurately pick appropriate companies to quote. Certain companies are suited to certain types of projects and the closer you can match the two the more competitive and appropriate your tender will be.
