Let our Estimators win your company work or let us work together to achieve your desired budget! 


Taking off and pricing a job can be very time consuming if done accurately. Our Estimators can help you manage the tendering process so your estimating department can focus on other enquiries or, so you can focus on growing and developing your business.


Our Construction Estimators have extensive experience on projects starting from £50,000 up to £35,000,000.


The Estimating Group can assist you with complete Estimating and Quantity Surveying Services irrespective if you are a subcontractor, main contractor, developer, general builder or architect.


Our Estimators will typically require at least two to three weeks’ notice depending on the amount of tender information and the size of the project, but we can also provide a fast return depending on the availability of our staff and on your requirements.


When we provide estimating services, all our take-offs are done by our experienced estimators very accurately, and we always make it a priority to double check all take-offs before transferring them into a Bill of Quantities, so you can rest assure that all quantities are accurate.


We can provide your company with Freelance Estimating Services, Budget Estimating, Cost Planning Services, Bills of Quantities, Builders Schedule of Works or Fix Price Estimates.

Depending on your requirements when we provide estimating services, after creating the bill of quantities, we can send out enquiries to your preferred subcontractors, or we can use our comprehensive list of subcontracting companies, and we can select the required subcontractors depending on the size of the project and location. Once we create this list of subcontractors, we can share it with yourselves for your approval. Our Estimators will then split the document according to each trade and send it to the relevant companies and on return we will create the comparison within Conquest. Our construction estimating services UK will be happy to assist.


If the tender has a short return period, while using our construction estimating services, we can price it ourselves using current competitive market prices. Alternatively, if required, we can go into detail, and we will create rates tailored to suit your company costs and profit margins by building every rate from scratch using the first principal of estimating (labour, plant and material). Every construction company is different and unique, so please let us know your requirements beforehand, and we will adapt accordingly to suit your company’s needs.


Using our detailed labour resources summary, you will be able to see exactly how many hours your workers should spend in total, and you can work out quickly based on how big your site team is how long it will take you to complete the construction project.

The material breakdown summary we create will provide you with all the required quantities and all the materials types required for the project. Your buying department or site manager will welcome this document.  Depending on the return date our estimators will send it on your behalf to your suppliers so we can then get their exact prices and update the detailed Bill of Quantities or we will use local material rate to populate the material costs.


If you would only require us to create a bill of quantities or a schedule of works for your company to input your bespoke prices, please let us know, and our team of construction estimating services would be happy to assist.


If the drawings are updated, or if certain items are taken out from your scope, we can quickly pick up all the changes and update the Bill of Quantities to suit.


Using our take-off software, we can easily overlay sets of drawings, and we can accurately pinpoint and asses all variations to the original drawings.


On completion, our Estimators will highlight all the risk items you may or may not encounter and create a document with all the assumptions we have made during our take-off and while pricing the Bill of Quantities. We will give you all the required details about all our allowances so you make an informed decision when choosing what profit margin, you would like to put on each project.


The end result is always dependent on the input of information received by us from yourselves at the quotation stage.


We encourage every client to let us know how they will want to proceed on site if successfully securing the enquiry and our Estimators would request details of any directly employed labour trades or any owned plant before creating the Bill of Quantities.


Depending on the nature of the project and the location we would sometimes request photos from site visits, or we will travel to the site to assess the access and potential risks.


We would typically exclude preliminary costs from the project as every company have their template for this and each company evaluates the duration of the project differently.


On completion of our freelance estimating services, we will provide your company with all the emails, quotations, and excel version of the bill of quantities.


We can assist your company with competitive tendering and estimating services, and we are a great asset to many companies. Contact us so we can become a great asset for your company as well.

General and detailed information about estimating services and standards being used when providing construction estimating services

A building estimator/cost estimator is an individual that quantifies the required resources such as labour, plant and material that are needed to complete a construction project and analyses quotes that are received from different sub-contractors and suppliers. Building cost estimating can concern diverse forms of construction from residential properties to hi-rise and civil works.

Estimators can produce bills of quantities, schedules of works and cost plans based on drawings, specifications and any other tender documents provided by the client.

Part of the duties and responsibilities of an estimator include:

•    Identifying and assessing client requirements.

•    Researching the costs of labour, plant and material.

•    Taking off all the quantities for the project.

•    Liaising with the client for overheads and desired profit.

•    Sending out enquiries and collecting quotes from sub-contractors and suppliers and identifying inclusions and exclusion while making allowances where required to create a like for like comparison.

•    Identifying risks on a project and allowing for these in the estimate and within the tender clarifications.

It is crucial for estimators to be good forward-planners and to be capable of using a wide range of information and a degree of judgment to formulate accurate cost assessments. Estimators will often work closely with construction managers, planners, buying departments and commercial and design teams.

An essential part of the estimating process is the taking-off and quantifying all the quantities within the project. The Process of taking off all the elements of the construction project is done by counting, measuring areas, calculating volumes, calculating weights and sometimes even quantifying time. Our Estimators are doing all the takeoffs digitally as opposed to by hand thus saving time for this process, and we can also create PDF documents highlighting the items we have measured on each drawing. All the measured elements will be transferred manually into Conquest to create the Bill of Quantities.

The bill of quantities (BoQ or BQ) is a document prepared by the cost consultant (often a quantity surveyor) that provides project-specific measured quantities of work identified by the drawings and specifications in the tender documentation and by experience.

Once the creation of the bill of quantities is complete, this is issued to tenderers, (subcontractors) to prepare a price for carrying out the works. The BoQ assists tenderers in the calculation of construction costs for their tender, and, as it ensures that all subcontractors will price the same quantities.

This priced bill of quantities constitutes the tenderer's offer.


It is essential that the bills of quantities are prepared in accordance with a standard. This helps avoid any ambiguities or misunderstandings and so helps avoid disputes arising through different interpretations of what has been priced.

For measuring building works, we use the Standard Method of Measurement (SMM7) as well as the New Rules of Measurement (NRM2) depending on the client's requirements.

For civil engineering works, we use Civil Engineering Method of Measurement (CESMM).


For Highway projects, we would follow the Method of Measurement for Highway Works Volume 4. (MCHW 4)

Even with the above standards in place, there are still many common mistakes that can be done in the Bill of Quantities on which we have implemented many systems in order to prevent them.


Common mistakes in the bill of quantities are:

  • Inaccurate measurement of quantities.

  • Insufficient information is given in the descriptions

  • The inclusion of irrelevant preliminary items

  • Omissions and discrepancies between the BoQ and the drawings or specifications

  • The omission of temporary works items.

  • Omissions or double-counting of items

  • Incorrect understanding of the work method.

  • Past performance used to assume future productivity.

  • Mistakes arriving from the inexperience of the estimator.

  • Ignoring the relationship between items of work.

  • Inaccurate assumptions regarding items in the BoQ.

  • Arithmetic errors.

  • Differences in currencies not considered.


Costs Plans

NRM1: Order of cost estimating and cost planning for capital building work, gives the following definition of an elemental cost plan:

‘…the critical breakdown of the cost limit for the building(s) into cost targets for each element of the building(s). It provides a statement of how the design team proposes to distribute the available budget among the elements of the building, and a frame of reference from which to develop the design and maintain cost control. It also provides both a work breakdown structure(WBS) and a cost breakdown structure (CBS), which, by codifying, can be used to redistribute work in elements to construction works packages for the purpose of procurement.’
