Following a competitive tendering process Actiform were awarded the contract to design, manufacture and deliver a 3 storey Off Site Engineered Office and Welfare Facility on behalf of the CVB Joint Venture at their Chambers Wharf Site.

In accordance with our clients commitment to prioritise river transportation, all the off site engineered sections and materials where delivered to site via pontoons on the River Thames, and offloaded directly from the pontoons onto site.

The building was designed to house approximately 140 Office Staff, and providing Welfare and Canteen Facilities for approximately 200 personnel, along with Occupational Health Facilities, Training Rooms, a Gym and Laundry Facilities.

The building features included:

  • Suspended Ceilings
  • VRF Air Conditioning Systems
  • Dehumidifier Systems (to Dry Rooms)
  • DDA Platform Lift
  • LED Lighting throughout operated from PIR’s
  • Infa Red Operated Taps
  • Automatic Sliding Entrance Doors
  • Feature Windows (solar glazed)
  • Plumbed in water chillers
  • Fully glazed partitions with integral blinds
  • LFolding/Stacking wall system

The project was completed on budget and on time, and resulted in Actiform being awarded a further 3 projects (Greenwich, Deptford and EARL Pumping Station) on this section of works.

The service we received from Actiform in acquiring additional modular office space was exceptional. From the initial flexibility around design to meet our needs, through to achieving delivery and install on time was first class. Nothing was too much trouble and the communication throughout the process was excellent, whilst providing a value for money solution.

Having used Actiform to supply a large compound set up on a Smart Motorway project, the service received was second to none. From the initial enquiry to the final installation, all aspects of the project went to plan. The cabin design and layout was revised on numerous occasions and no request or alteration seemed to be too much trouble. All communication, planning and installation was very collaborative and all key dates and deadlines were actually completed ahead of programme.

Corin Feltham in particular offered his wealth of knowledge and experience throughout the process along with introducing some excellent ideas to save both time and money. All in all a good experience working with Actiform and I wouldn’t hesitate to use them again on other schemes.

Back in the autumn of 2015 we had a requirement to procure offices and welfare facilities of 3,000m2 plus over 3 floors for our Tideway-East project in Bermondsey, London.

We went out to tender and Actiform provided a construction package that we eventually purchased. Right from the start – sales , tender, design, manufacture, installation and aftercare support, Actiform have been very professional, proactive and suggested cost saving solutions without compromising our facilities. Their site installation team had all the correct RAMS and certification to carry out our installation in a planned and well organised time scale.

From the beginning both parties, CVB JV and Actiform, have worked openly and honestly together and we have an excellent working relationship. I cannot praise Actiform enough and would certainly recommend them to any prospective client.
