The guys on site in Birmingham are over the moon with the Sealed Manhole System. They will certainly be using it again on other sites. The CPM service is brilliant.
Tony Bronsema, Buyer, Churngold
Expanded Structures has found that the Perfect Manhole finish quality is far better than that of a traditional manhole and that he and his team can save time and costs on installation. The safety benefits are excellent as excavations are not left open when waiting to surround the manhole in concrete as none is required when using the CPM Perfect Manhole. In addition an operative is not required to go into the excavation or confined area to bench the manhole as this is done when the manhole was manufacture.
Michael McCarthy, Site Engineer, Expanded Structures
Now we have had working practice of the Perfect Manhole system, we would like to use them extensively due to the speed and ease that the overall solution provides for all drainage applications.
Alan Prydden, Managing Director, G A Prydden
The Perfect Manhole is a fantastic innovation which resulted in speed of construction and minimised health and safety issues.
Alan Young, Site Manager, Kier North West
CPM’s Perfect Manhole is a quick, effective and a safe way of constructing manholes and the take off service offered always meets our programme.
Scott Steel, Kamm Civil Engineering
The CPM Perfect Manholes saves us construction time which is vital in our industry.
Jim Townsley, GMI
Having recently completed four projects with the CPM Group I’d just thought I’d drop you a short note to congratulate you & your install team on the professionalism, can do attitude and ability to overcome all obstacles that presented themselves with your installation of the Redi-rock wall system, especially on the trickier sites. As you are aware the four projects that we completed were carried on live sites with minimal disturbance to the operations of the staff, which made for a very good working relationship with the on site FM team. The visibility that we were able to give them weekly in our look ahead work schedule & more often daily as the weather dictated, helped us deliver the project to our client flawlessly and enabled them to return to business as usual without any defects.
Murray Martin, Contracts Manager, Sharkey Contractors
Redi-Rock was chosen over numerous alternatives for this scheme on account of the sensitive nature of the watercourse and our desire to minimise the use of in-situ concrete or mortars. The Redi-Rock walling with its ease and efficiency of installation became the clear solution. The completed installation looks very good next to the existing stone masonry and we were impressed by the ease with which the finished wall came together and more importantly it was completed within the timescale allowed with the SEPA license. The site was just below a bridge on route to Dalry train station and we regularly had an audience watching the wall being built.
Senan Kelleher, Director, Kelsen Technical
Redi-Rock modular walling is an ideal choice due to the speed and ease in which our men can build a wall. With the reduced excavations and backfill needed, Redi-Rock can be laid in all weathers with the finished wall looking like a natural stone wall it requires minimal maintenance which is good news for everyone involved.
Roger Cox, Purchasing Manager, McPhillips (Wellington) Limited
The fast-track nature and simplicity of the Redi-rock system was perfect for the programme requirements at Primrose Hill, its innovative assembly and design enabled quick and safe installation. Due to the surrounding Yorkshire Black Stone cladding on neighbouring properties Redi-rock was tasked with matching the natural colour of the above stone and it was done with surprising ease and effectiveness, also to everyone’s satisfaction, including the local planning office. The Redi-rock system also benefited the client as it was a third cheaper than the proposed traditional design and the programme for the works was nearly halved due to its simple installation.
All in all an excellent product that ticks all the boxes and we as a company would not think twice in procuring this system again as both a time and cost saving solution to retaining structures.
Gareth Hill, Project Surveyor, Wates.
Redi-Rock is an ideal solution for the Tregaron Flood Relief Scheme, in view particularly of the speed with which flood walls can be constructed.
Tim Hopkins Project Manager, Environment Agency
Fitting the Hydro-brakes after the drainage had been laid shows that the chambers do not have to be constructed on line and as such the lead time for site means that the works can continue and the wait for delivery does not become a holding point for the contractor.
Sharon Sutton, Section Engineer, BAM Nuttall
I believe that the design CPM provided the ideal solution – from setting up pumps to deal with the high water table and establishing the temporary works to provide the earth works support both the pump chamber and valve chamber were placed and back filled within eleven working days. The integrity of the design gave the team involved the security that the chambers would not leak and the accuracy of the manufacture within the chambers was so good that the installation of the pump gear that could have taken four days was completed in just over one. Facing a similar challenge in the future, be it with a pumping station or a large control manhole, I would certainly discuss it with CPM again.
Symon Wheeler, Brandwells
We have just installed a 6 meter deep manhole on a project in Salisbury and the great advantage of the Perfect Manhole is that you can complete a job in a day; saving on cost and time as opposed to using manhole shutters to surround the ring, where you had to do the job in three lifts as the height of the shuttered is only 1.8 high, which took time and a lot more effort.
Another advantage of the Perfect manhole is a health and safety feature as you are able to close up the excavation on the same day which has got to be a step forward going into the future of building manhole.
Stephen Few, Contracts Manager, C J Lee
CPM provided 1200mm diameter sewer pipes incorporating a pre-cast dry weather flow channel and three manhole solutions, including stop end bends and side entry/bend which were correct to the millimetre and to the degree, which could not have been built any more accurately on site.
By supplying a product that has been tested under factory conditions it removed the need for working in confined spaces and reduced the site programmed by two weeks, not only reducing disruption to local residents but also reducing the costs associated with in-situ construction by 50%.
Rob Graham, Site Agent, North Midland Construction.
From a procurement point of view, ordering pre-cast chambers with Hydro-Brake already fitted wins on quality and was a good reason for going through CPM
Mike Brookes, Project Manager, Edmund Nuttall
CPM was commissioned by Balfour Beatty Regional Civil Engineering to design and manufacture a four piece, 8m diameter cover slab for a pump station. Their professional approach in dealing with various design change requests was matched by their patience with our dynamic construction programme. The CPM team’s service throughout was second to none and I would certainly return to them on future projects.
Deon Albertyn, Site Manager, BBRCEL
If the sealed manhole installs as good as it looks coming off the wagon you have a smashing system there.
Tom Cochran, Engineer, Persimmon Homes (West Scotland)
We have recently installed a wall on our project at the Grange School and have found both the aesthetics and cost savings favourable and believe that a saving of 20% was achieved using CPM’s Redi-Rock modular walling.
Denis Cronin, Quantity Surveyor, Galliford Try
CPM currently supply Churchgold Construction with pre-formed manhole bases and rings that make the construction of manholes very much more reliable, and help us to improve on the quality delivered to our clients.
Chris Tipple, Churchgold Construction
I was very impressed with the service and communication from start to finish from yourselves.
William Johnston, Contracts Manager, Construction Marine Ltd
The Redi-Rock™ product is very simple but massively effective. It is easy to install and the end product looks fantastic. I would definitely use this product again. The service we received from CPM was second to none. They always made a conscious effect to put our needs first.
Jamie Turner, Site Agent, Dawnus Construction
The bespoke cover slabs fitted together well, the quality of the finish was good and all dimensions worked out to the structure. Very pleased with the end result.
Paul Hollard, Site Manager, Wessex Engineering and Construction Services
Thanks for all your help on the supply of the CPM Perfect Manholes. We have cut our installation times dramatically and decreased our workload to ensure we have met our milestone targets. This would not have been possible without your assistance and help throughout. We have currently installed almost all the stock you have supplied and out workforce are impressed with the efficiency and ease of the system.
Jaimie Lawson, Senior Engineer, Morgan Sindall
