Terms and Conditions



These supplementary conditions are used, partly, to raise the awareness of the Hirer’s responsibility when requiring a concrete pumping operation; and, to define contractually the extent of the Owner’s and Hirer’s responsibilities as between themselves.

For the avoidance of doubt, when the hire is subject to the CPA’s Model Conditions for the hiring of plant 2011 (CPA Model Conditions), the Owner is not a specialist sub-contractor and/or sub-contractor of the Hirer.  The Owner will supply Plant pursuant to the CPA Model Conditions together with these Supplementary Conditions to form the contract between the Owner and the Hirer.


1.1          These supplementary conditions are applicable to the fire of concrete pumps and associated plant only (Pump) and shall be referred to as the “Supplementary Conditions”

1.2          Unless the context suggests otherwise words and terms in the Supplementary Conditions shall have the same meaning as in the CPA Model Conditions.

1.3          If any conflict shall appear between any provisions of the Supplementary Conditions and the provisions of the CPA Model Conditions then the former shall prevail.



The hirer is solely responsible for the concrete specification and the provision of a suitable and sufficient supply of concrete of a consistency, which is readily pumpable at a suitable rate.  The Hirer shall be responsible for informing the Owner of the nature and extent of any additives that may be incorporated into the concrete.  The Owner accepts no responsibility for delays in output arising from the Hirer’s failure in this respect.  The Hirer is also solely responsible for ensuring that the concrete supplies is of a quality and strength suitable and sufficient for the Hirer’s purposes.


The Hirer will be fully responsible for the management of the entire pumping operation in accordance with the terms of this contract.  The Hirer shall provide at its own expense, and shall ensure that a competent supervisor is in attendance at the beginning, throughout and at the end of the pumping operation to assist the operator.


A safe system of work will be established by the Hirer and this must be followed for each concrete pumping operation under the Construction Plant-Hire Association’s Best Practise Guide for the Safe Use of Concrete Pumps and in accordance with British Standard 8476:2007, whether it is for an individual pour or a series of pours.


The Hirer shall provide the following facilities without charge to the Owner for such times as is reasonably required during the Hire Period:

5.1          Cement for grouting the pipelines at the rate of 50kg per 20 metres between the Pump and the point of discharge.

5.2          An adequate piped water supply at the pump position.

5.3          Temporary light at the Pump position and along the pipeline when required.

5.4          Facilities for washing out the Pump and adequate assistance in cleaning any spillage.

5.5          The Hirer shall ensure that sufficient competent labour is made available to assist the Operator prior to pumping, during pumping and on completion of pumping; and if necessary when the pump leaves site of operations.

5.6          Any additional labour required in respect of pipeline erection or dismantling.

5.7          Suitable supports for pipelines and anchorage points for vertical pipelines.

5.8          All access scaffold and ladders necessary for the safe and proper execution and progress of the work.  The Owner has not included the cost of providing, erecting or moving any necessary scaffold.

5.9          The Hirer for Health and Safety reasons will provide a banksman who will assist the driver when the mixer lorry enters, traverses or leaves the site.


The Hirer shall provide and shall clearly indicate to the Owner’s operator the suitable points where the pump is to be set up.  Without prejudice to clause 7 of the CPA Model Conditions the Hirer shall be entirely responsible for the ground upon which the Pump is to traverse and be set up.  The hirer shall be fully liable to the Owner for any damage to the pump caused by ground conditions and shall indemnify the Owner and hold the Owner harmless against any liability, expense, loss or damage caused by ground conditions.


In the event that the Contract specifies a particular type of Pump, the Owner reserves the right to supply a suitable alternative Pump to that specified.  Acceptance of the Pump on site shall be acceptance of the variation of the Contract in respect of the Pump supplied and the Owner shall have no liability to the Hirer in respect of that variation.


Any concrete blockage or chock either within the pump machine or pipeline will not be construed as a breakdown under clause 9 of the CPA Model Conditions and/or the contract.


9.1          The Hirer shall allow the pump to arrive on site up to sixty minutes before it is ready to commence pumping and to allow up to sixty minutes after it has ceased the pumping operation to de-rig, wash out and prepare for travel.  These periods of time will be charged at the working rate as agreed.

9.2          Concrete shall not be delivered to site until such time as the Pump operator deems that he is ready to commence pumping operations.

9.3          If the Pump is delayed in leaving the site, which is outside the Owner’s control, this period will be charged at normal working rate to the Hirer.


The Hirer shall take out and maintain insurance against any and all liabilities the Hirer might incur under the contract.  The Owner reserves the right at any reasonable time to require confirmation that the Hirer is complying with their insurance obligation.


The Hirer shall provide a competent person to sign any delivery docket presented in respect of the delivery of any concrete and/or materials pertinent to the pumping operation.


The Hirer’s order is accepted on the basis that the Hirer will book his requirements on a daily basis in accordance with such arrangements as may from time to time be agreed between the Owner and the Hirer.  One clear working day’s minimum notice of cancellation is required and the Owner reserves the right to charge the Hirer for any loss incurred due to insufficient notice being given.


Unless otherwise agreed the quantities of concrete pumped by the Pump shall be assessed (except to the extent that the Owner shall show that any such assessment is not reasonably accurate) by the reference (in case of ready mixed concrete) to its supplier’s delivery dockets and (in case of site mixed concrete) to the quantity of concreting materials used by the Hirer and to the mix-proportions on which the Hirer has based his production of concrete.  Where assessment is made by reference to mix-proportions the Hirer shall afford the Owner all such facilities as the Owner may reasonably require for the verification of quantities of material used and of the accuracy of the mix-proportion figures.


The Hirer shall be charged for a full Working Day, including lunch and rest breaks taken by the Driver or Operator or any person supplied by the Owner.



The Owner shall be responsible for compliance with the Construction Plant-Hire Association’s Best Practise Guide for the Safe Use of Concrete Pumps and where appropriate British Standard 8476:2007


If the Owner provides an operator with the concrete pump, Clause 8 of the CPA Model Conditions will apply and the operator will be deemed to have the appropriate qualifications, training and experience to operate the Plant.


Any dates specified by the Hirer and/or the Owner for delivery of the Pump are estimates only and time for delivery shall not be made of the essence by notice.  If no dates for delivery are so specified, delivery shall be within a reasonable time.


The key to a successful concrete pump pour is to manage the pour from ordering the pump and concrete, through organising the site, to supervising to pumping operation. Some guidelines are set out below to assist with planning a pump pour.

When ordering a pump please give the following information:

  • Company name
  • Contact name and telephone number
  • Full site address including postcode if known
  • Date and time for the pump, allow approximately 1 hour for the pump operator to set up the pump or Pipe Line
  • Size of pump required
  • Volume and type of concrete including any admixtures, additions, fibres etc
  • Brief description of the pour e.g. footing, external slab, bridge deck etc
  • Any other special requirements – additional pipeline, small diameter pipeline (75mm) second man etc.

To ensure a safe and efficient pump pour, please supply:

  • Clear and safe access to the pump set-up area for the pump and the truck mixers
  • A level area of hard standing, with no overhead obstructions, on which to set up the pump
  • A set-up area that is strong enough to support the maximum outrigger loadings of the pump
  • Cement to grout the pipeline – 1 x 25 kg bags per 10 metres of pipeline
  • Somewhere to deposit excess grout
  • A good pump mix concrete of S3, S4 or S5 consistence. Your ready mixed concrete supplier will advise
  • A competent concreting gang to lay the concrete
  • A suitable place for the operator to wash the pump out at the end of the job. At least 1/3 cubic metre of concrete will be left in the pump after the pumping operation
  • A good supply of water will help the operator, although the pump does carry its own supply.

The sequence of a typical pump pour:

  • The pump will arrive and the operator will liaise with the contractor before setting up the pump, pipeline (if required) and preparing the grout
  • The concrete mixer truck will arrive and back onto the pump
  • The pump operator will then grout the line and commence pumping. It is good site practice to pump excess grout to waste, not into the pour
  • The concrete will be placed into position using the boom where possible. Where ground-line is used, the concreting gang will need to move the pipeline around as the pour progresses
  • Cautionary note: Concrete is pumped at high pressure. All personnel should be made aware of the risks and dangers associated with end hose usage
  • When the truck mixer has discharged its load, the mixer chutes will be cleaned before the mixer leaves. The chutes should not be washed into the hopper as this could cause a blockage and affect the quality of the concrete
  • The next mixer will then arrive, back on to the pump and discharge its load
  • At the end of the pour, the pump operator will clean all the concrete from the pump and pipeline. This operation will take approximately one hour, more if the job involves a long pipeline
  • The pump operator will then put the boom back into its travel position and load all the ancillary equipment onto the pump
  • The job sheet will then be prepared for the contractor to sign
  • The pump will then leave site and travel back to the depot.


  • Unless otherwise stated, terms of payment are on completion of work
  • The Owner reserves the right to refuse to execute any order if the arrangement for payment or the Hirer’s credit is not satisfactory to it, and to suspend or discontinue the Owner’s service to any Hirer whose account is overdue for payment. Notice of any suspension or discontinuance shall be given by the Owner to the Hirer in writing as soon as possible.
  • The Owner reserves the right to set off against any sums due to the Hirer from the Owner
  • Value Added Tax will be added to all charges, if applicable
  • We reserve the right to claim interest and compensation under the Late Payment of Commercial Debts (Interest) Act 1998 and it is agreed that the term implied by that Act shall apply after any judgement as well as before
  • If for any reason any payment is not made when due, the Owner reserves the right to be paid on an indemnity basis any costs the Owner incurs in recovering any money due under this contract ( and the costs of recovering such costs) including the Owner’s administration costs and any costs incurred with lawyers or debt collection agencies. The Owner’s administrative costs may include the cost of employing the staff concerned and the overheads attributable to them for the time spent.  In calculating the Owner’s administrative costs credit will be given for any compensation due under the Late Payment of Commercial Debts (Interest) Act 1998
  • If proceedings are issued a minimum contribution of £300 (in addition to the fixed costs of issue) will be claimed towards any costs incurred with lawyers.
