Feasability & Drainage Design
New drainage schemes or improvement schemes often represent significant capital expenditure. Before funds are committed to a project it is necessary to investigate and understand the site specific constraints that will determine the most effective solution. Sites and potential solutions can be constrained by ground conditions, existing services, traffic, access, other developments, etc and these factors must be taken into account.
Fundamentally, this requires a thorough understanding of the problems and project drivers, such as the causes of flooding or sewer capacity restrictions, before any solutions are considered. Performance objectives and the attendant risk of exceedance of the design parameters must be fully considered as part of defining any solutions. Feasibility studies will also consider a number of options that take account of site constraints to ensure that all solutions are pragmatic, practical and buildable.
Our Engineers have an in-depth knowledge of drainage and sewerage issues including hydraulic modelling and problem definition that allows us to understand root causes of problems and thereby develop the most appropriate solutions.
The key aspects to undertaking feasibility studies can be summarised as:
- Define the project drivers and design parameters for the scheme
- Identify physical, third party and programming constraints
- Fully understand the problem
- Identify practical options to resolve the problems
- Identify Health and Safety advantages/disadvantages between options
- Assess relative costs of construction and maintenance of options
Our Engineers will set out the options to achieve your objectives and will establish whether these objectives can be cost-effectively achieved, providing budget costs for the identified solutions.
