Providing solutions for our client. 

For this particular scheme nmcn were approached by their client, Affinity Water, to provide a solution to issues they were experiencing at Uttlesford Bridge. Uttlesford Bridge is a major water treatment works located in Essex, England. The plant, which is the main supply to Saffron Waldon and surrounding villages, was dated and was causing nuisance maintenance issues which in turn led to customer complaints. Affinity Water wanted to replace the dated equipment with a new, more efficient system to ensure their customers were receiving an exemplary service.

The strategy behind nmcn’s innovative approach was to provide the client with the best possible solution. nmcn’s proposal was based around an off-site build approach to construction, Skilled Assembly in a Factory Environment (SAFE), which included a 3D laser scan of the site prior to the commencement of works and full utility survey of underground services using a ground penetrating radar (GPR).

This approach to off-site construction means that products are produced in a safe environment resulting in a number of benefits, improved health and safety, reduction in wastage of raw materials, reduced carbon footprint, reduction in environmental impacts, to name but a few. This innovation benefits from our manufacturing expertise and workshops which are purposely set up to accommodate off-site construction.

Challenge:

Uttlesford Bridge is a major water treatment works located in Essex, England. As the plant was dated and causing nuisance maintenance issues, nmcn were tasked with replacing the equipment with a new, more efficient system. It was essential that the plant remained operational until the new process had been commissioned and ‘proven’.

Solution:

nmcn utilised their innovative Skilled Assembly in a Factory Environment (SAFE) approach to construction which meant that the design and development of a 20m x 4.5m chemical treatment plant could be fully built and tested in our construction facility, prior to being transported to site. The treatment plant consisted of, fill points and panels, storage tanks, dosing rigs, sample boards, UV reactors, pipework, structural steelwork and a main site Motor Control Centre (MCC). It is the biggest of its kind in the country. This innovative approach to off-site construction means that products are produced in a safe environment resulting in a reduced programme of works, improved health and safety, and reduction in wastage of raw materials.

Results:

Due to the limited shut down period available on site installing the equipment was deemed a high risk activity. Therefore an offsite build was very attractive to the client, and not to mention the reduced health and safety issues of building on site, but also reduced construction restrictions and noise to local residents.

nmcn carried out an initial 3D laser scan of the existing site and produced a fully detailed AutoCAD model. Once the AutoCAD model of the proposed improvements had been completed it was laid over the model of the existing works to ensure that the equipment being built off site would be a perfect fit once transported. There were some slight modifications required which this process brought to light, had this issue been dealt with whilst on site it would have caused a delay to the schedule of works and an increase in costs.

Utilising the various innovative technologies on the Uttlesford Bridge project enabled nmcn to make a financial saving of £110k from the original costings based on traditional onsite installation.  

Testimonials

Off-site manufacturing and assembly provides a significantly reduced health and safety risk to our people, right first time solutions, reduced programme and environmental impact, increased productivity and lower costs, whilst providing an enhanced customer journey, why settle for anything less?
