Our expertise in commissioning, commissioning management

and soft landings covers all aspects of building engineering

services and is based on experience gained working in this

challenging part of the industry.

From full commissioning management and HVAC

commissioning to system and plant validation, verification and

water treatment and testing, we can offer you a

comprehensive service.

Our clients include office land lords and tenants, design and

build contractors, developers and owner/occupiers.

Additionally, we have worked for mechanical and electrical

contractors and specialist suppliers across a number of

projects.

“We recognise the complexities of building services design and the importance of the need to support the operational aspects of any services project”

Commissioning is the process of ensuring that systems are designed, installed, tested, and capable

of being operated and maintained according to the owner’s operational requirements. It is a

continuous process that identifies, prevents, and resolves problems as early as possible, since

problems that are addressed early nearly always cost less to fix.

Our experienced commissioning managers specialise in ensuring M&E building services are

strategically planned, commissioned and signed off to ensure stringent compliance with the project

specification and the client’s requirements.

This involves managing, witnessing and verifying on and off site testing to ensure building/project

performance is compliant with the project requirements as well as CIBSE codes, BSRIA guidelines

and Part L building regulations and any specialist system requirements.

Our processes and systems are ISO 9001 and 14001 accredited and we are members of both

Constructionline and CHAS, in recognition of our commitment to ensuring we have robust levels of

heath and safety in place.

We are also a member of the Commissioning Specialists Association (CSA), the only body in the UK

aimed specifically at developing and improving the commissioning function to provide building

users, consultant engineers, main contractors and installation companies with a professional,

quality service carried out by trained and experienced staff.

COMMISSIONING MANAGEMENT

Planned refurbishments, change of use, fit out works and the purchase of property often results in

the requirement for existing plant and services to be validated. This provides assurance that the

plant and equipment is capable of achieving required performance criteria and establishes a

valuable ‘line in the sand’ between contractual responsibilities.

We can provide a full validation and verification service to ensure the appropriate checks and

reports are prepared, saving you from costly mistakes and potential disputes.

Our services include the preparation, processing and execution of validation plans, functional

specifications, installation qualifications and operational qualifications.

We can also provide specialist verification services for clean rooms, operating theatres, licensed

drug production facilities, data centres, cold stores, food production facilities and high care

environments.

VALIDATION AND VERIFICATION

Water Treatment and Legionella Risk Assessments

In conjunction with our specialist partners we can arrange, co-ordinate, witness and report on the

complete system. In addition, we can undertake legionella risk assessments and reviews for our

clients to ensure the requirement to comply with L8 is met.

Surveys

We carry out a bespoke survey service for clients on M & E systems. These vary from small

operational issues to the building-wide analysis of system design, previous commissioning and maintenance reviews.

Thermographic Surveys

We are equipped to undertake thermographic surveys of buildings, cold stores, electrical systems

and pipework systems for fault finding and validation.

Training Videos

We have an established working relationship with an experienced video production company to

offer a specialist training video service.

Fault Finding and Trouble Shooting

Along with our sister companies Silcock Leedham Consulting Engineers and Zero Energy Design,

we have many years experience of building construction and specialist systems and we offer a fault

finding service including ‘hands on’ testing, calculation verification and computer analysis.

OTHER SERVICES

We are a SLCE group company. Our group company model is based on offering a complete solution

to our clients.

All group companies are designed to allow full and transparent interoperability for our clients whilst

offering a mixed bag of specialisms to suit particular needs and requirements.

In addition to offering commissioning management services, through Silcock Leedham we have

Andy Taylor, Rotary, Yorkshire Ltd

Verisys have completed annual verification works of operating theatres and clean rooms at Derby

Hospital. This is an important exercise and requires a high level of detail and testing. Verisys

completed this task accurately and in a professional and timely manner and we will definitely use

them again to complete similar works.

Ivan Hodkinson, Skanska

NOVO Integration Ltd have worked with Verisys on many projects, including the commissioning of

B-Braun offices in Sheffield and Yorkshire Building Society Headquarters in Bradford. In all cases

works have met the programme requirements and issues have been dealt with clearly and

methodically to ensure the building services. I have nominated Verisys on various project and will

continue to do so in the future.
