Iris Traffic Management

IRIS Traffic Management is London’s leading infrastructure management and co-ordination service consultancy that supports construction, utility and other companies involved in projects affecting the local highway.

We provide expertise and experience for our clients to navigate successfully through the unique challenges faced when dealing with local authority guidelines associated with planning requirements.

Few organisations and projects have the possibility of functioning today without dealing with local government departments. Whether you need to suspend parking bays outside a house or looking to close a road for an extended period, there are lengthy and often complex regulatory processes to follow.

IRIS Traffic Management uses its knowledge, experience, relationships and resources to streamline processes, providing a unique and innovative service for our clients. We engage the correct local government departments on the client’s behalf to secure the necessary approvals and accreditations in a time and cost effective manner.
Closures and traffic management

Where works require the temporary closure of a highway (from roads to footways or city walkways), a Temporary Traffic Regulatory Order (TTRO) must be granted and diversions, signage and public notifications organised.

To apply for the TTRO it is necessary to identify what items and activities will be on or adjacent to the affected highways. Examples include:

  • Signs (e.g. diversion and temporary no entry signs) 
  • Lines 
  • Barriers
  • Hoardings
  • Skips 
  • Scaffolding 
  • Cranes or lifting equipment 
  • Signal controls e.g. temporary traffic lights 
  • Lighting (e.g. temporary floodlighting or hazard warning lamps) 
  • Marshals or banksmen
  • Parking dispensations and parking bay suspensions
  • Abnormal loads (i.e. greater than 40 tonnes)

The council will also want as much information as possible on how the traffic will be managed. Examples of what this might include are:

  • Type of traffic control 
  • Risk assessments 
  • Traffic modelling 
  • Scale maps
  • Diversion routes for vehicles and/or pedestrians
  • Draft consultation material (e.g. draft letters to affected local residents and businesses)

Once the TTRO has been approved and made enforceable it is the responsibility of the applicant to ensure all the correct infrastructure management systems are in place.

IRIS Traffic Management provides its clients with a professional infrastructure management consultancy and planning service, helping them deal with local authority stipulations and the requirements of the Traffic Management Act.

Section 61 applications

Section 61’s come from the Control of Pollution Act (COPA) 1974 which gives power to the local authority to control noise and vibration from construction sites. The basis of the legislation is that ‘best practical means’ (BPM) should be used to control noise and vibration pollution on site.

A Section 61 is a formal agreement between the contractor and the local authority. This agreement has to be applied for before work commences and allows the contractor and local authority to agree, for example noise levels and hours of work, and protects the contractor from local authority action.

Using our experience, knowledge and contacts, IRIS Traffic Management is able to manage Section 61 applications on your behalf.

If your development will have a significant impact on neighbouring premises from noise or vibration it is recommended that you apply to the Council for a "prior consent" under Section 61 of the Control of Pollution Act 1974. A prior consent will not normally be issued if work has already commenced and most local authorities require an application at least 28 days before work commences.

The control of noise applies to the following works:

  • The erection, construction, alteration, repair or maintenance of buildings, structures or roads
  • Breaking up, opening or boring under any road or adjacent land in connection with the construction, inspection, maintenance or removal of works
  • Demolition or dredging work
  • Any work of engineering construction

To facilitate the prior consent application it is recommended that a Pre-Construction Ambient Noise Survey is undertaken to enable you to assess the impact of your proposed work. IRIS Traffic Management is able to carry out these surveys and provide a comprehensive report.

The survey should include monitoring results for daytime (0800-1800), evening (1800-2300), night time (2300-0800) and Saturday/Sunday/Bank Holidays.
