Infrastructure

Our experience in highway design ranges from estate road design to major interchange improvements.

Our involvement may be a simple crossover agreement to gain access to a small development to designing a new link road to serve 1200 units.

With developments scattered across much of the country, JMS have experience in dealing with many of the Highways & Water authorities. In most cases this liaison will involve gaining approvals for onsite Section 38 Agreements as well as off site Section 278 Agreements.

JMS have the expertise and most up to date design software required to deliver all types of carriageway design.

Under the National Planning Policy Framework (NPPF), Local Authorities are encouraged to adopt a proactive approach to mitigate and adapt to climate change, taking into account the risk of flooding in line with the objectives and provisions of the Climate Change Act 2008.

National Planning Policy Guidance (NPPG) states a site specific Flood Risk Assessment (FRA) is required for sites of greater than 1 hectare in Flood Zone 1, for all proposals in Flood Zone 2 & 3 regardless of development size. A FRA can also be requested where there is an identified critical drainage problem.

JMS have extensive knowledge and experience in producing FRAs for all types of development. Our FRAs will assess the risk of flooding under all current guidelines and consider the potential fluvial flooding, groundwater flooding, existing sewers, surface water flooding and infrastructure failure.

Using drainage design software and liaising closely with the relevant governing bodies, JMS have the ability to provide a comprehensive FRA that will address all the questions asked by the planning process.

Although the Code for Sustainable Homes has now been withdrawn, the principles and requirement to demonstrate minimal impact from development remain.

JMS have wide experience of all forms of Sustainable Drainage systems (SuDS) from the use of private and adoptable permeable paving to wet and dry swales, infiltration and detention ponds, the use of landscaping to convey and clean surface water.

If designed in from inception, SuDS schemes can offer a very economical drainage solution with added value and ecological benefits.

With the ever growing pressure to deliver housing developments, JMS understand the need to produce timely and economical engineering input to such schemes.

From pre-purchase and planning assessments where the identification of cost and program issues is key to hitting the deadlines on delivery design packages, JMS have a proven track record of supporting residential developers.

JMS can provide an all-in-one pre-application Transport Planning service to assist developments in meeting requirements to promote and encourage the use of sustainable transport modes.

In consultation with the Local Highway Authority, we can prepare a Transport Assessment or Transport Statement to be submitted in support of a planning application, comprising an assessment of the likely trip generations of a development proposal and, where necessary, conduct a full assessment of the impact on the local highway network and design mitigation measures in conjunction with our Civil Engineering team.

JMS can also design bespoke Travel Plans to meet Local Authority approval and assist users of a development in making sustainable transport choices.
