Following the initial site assessment, a site survey would be carried out to gather all the existing dimensions and a photographic survey to document the existing site. Usually within 1-2 weeks, the initial drawings are prepared with options for the client to consider and can be discussed with us to agree a way forward for the best proposal. We always ensure communication with the clients liaising with them the optimised design solutions, amending drawings to the client’s feedback but making sure that they are feasible for planning application. Once everything is finalised and approved by the client, the application will be submitted to the local authority.  

Before undertaking a design project we would assess the history and context of the site and its surroundings. We research the local planning authority and establish what planning applications previous neighbouring properties have proposed, either accepted or refused. We also examine whether the property is under a Conservation Area, a listed building or within a flood risk zone. These factors would affect the planning applications and additional documentation is required to supplement the proposal. However, such constraints we would guide the client appropriately.

We submit most applications online using the planning portal. However, there are occasions (usually for larger developments) when it may be necessary to prepare a written application with bound drawings and documents. Please note – CIM Services cannot guarantee that planning applications will be granted.

Full planning applications include:

  • All existing drawings of the property (floor plans, elevations, sections)

  • All proposed drawings (floor plans, elevations, sections, site plans)

  • A detailed Design and Access Statement (if required)

  • Heritage Statement, Flood Risk Assessment, Arboricultural Report etc 

  • (we will advise if these are required for your planning applications)

  • Site plan and block plan, Ordnance Survey Map

  • Application forms, Notification letters, CIL Questions



Building regulations drawings set the construction standard for design and building works for many alterations to existing as well as new properties, and new builds. Building regulations are put in place to ensure health and safety in and around the buildings. CIM Services have the experience and knowledge to work on building projects and design these according to UK building regulations as seamlessly as possible. The legislation governing building regulations is constantly evolving and becoming increasingly complex. Even from the simplest domestic project to the most complicated large-scale development, all building work has to pass these rigorous standards.

The local authority’s Building Control department, or a private certified approved building inspector, will also have to check the building regulation drawings to ensure they comply with current UK regulations. Once the drawings have been approved, Building Control, or an approved inspector, will visit the construction site at critical stages of the build to ensure that the building work carried out is to a sufficient standard.

Building Regulations – The Outcome

At the end of construction, the building inspector will visit the site to issue a final completion certificate to prove that all works completed complied to the UK regulations. The building inspector has the power to refuse the issuing of a completion certificate if the building work does not comply. It is therefore vital that you choose a company which has experience of taking a project through to the issuing of a completion certificate.

Building Regulations – Our Expertise 

At CIM Services, we can help provide you with the necessary documentation for minor works such as house alterations and extensions, up to large scale new build developments and conversions; to gain approval from Building Control for your project



Structural Calculations – The Stages

After planning approval and during the building regulation drawing stage, you need to appoint a structural engineer to obtain the structural calculations. From a straightforward project (single storey extension) to a larger scope of works (new build flats/developments) a structural engineer is required. We provide structural consulting engineering services to owners, developers, and contractors for projects located throughout the Home Counties.

Our Focus at CIM Services

Our focus is developing structural systems for buildings of all sizes and complexities of architectural projects. We are known for our innovative, effective solutions for challenging structures and sites and for delivering successfully even when it seems impossible. Structural calculations are required by a wide range of clients for a variety of projects and materials.

Our Structural Engineers

Our engineers have experience of designing structures using steel, concrete, glass, timber and aluminium, they are aware of market conditions and advise on the appropriate design of a particular project. The structural engineer is most concerned with the foundations, walls, columns, beams and roof to ensure total stability. The structure will form the skeleton and the base of the extension/new build, so it is vital that structural calculations are made, and correctly, to avoid any problems throughout the life of the building. The quality of our service is reflected in our excellent repeat client list, which includes residential, commercial and leisure industry clients. Our ethos is to be helpful, approachable and useful to all.



What is a Tender Pack?

Tendering is the process by which bids are invited from interested contractors to carry out specific packages of construction work. It should adopt and observe the key values of fairness, clarity, simplicity and accountability, as well as reinforce the idea that the apportionment of risk to the party best placed to assess and manage it is fundamental to the success of a project.

A tender pack is a document compiling all the necessary materials and details required for the build phase. This will make it much easier for you to be in control of your building project.

Why have a Tender Pack?

A tender pack can be given out to different contractors to obtain a like for like quote for their construction fees. The principle of tendering is to ensure that true competition is achieved, as it is evaluated by applying certain criteria. These criteria may be expressed in terms of financial matters, comprising a simple assessment relating to tender sums, or more complex financial evaluation, including consideration of projected costs over the life cycle of the completed project. Providing contractors with just building regulation drawings will not be enable you to  obtain an accurate quotation, as each contractor will specify different finishes resulting in very varied quotations.

CIM Design and Build can help specify for and with you the most suitable finishes which will be followed out at the construction phase so that you can be on top of the project and have no hidden charges sprung on you. It could also address other non-financial factors such as time and proposed methods or levels of capability; or sometimes a mixture of both – collectively referred to as a ‘quality/price balance’ or ‘matrix’. 



When reaching the construction phase of your project, we can branch out to provide guidance and recommend services for the project management. This stage is recommended by us, particularly on larger projects, because we work closely with many project managers, who can help streamline the process and will be familiar with your project to guide and manage the team:

  • establishing the project objectives

  • co-operative team working and motivation

  • benchmarking progress against key performance indicators

  • managing the design co-ordination and procurement process

  • managing the construction teams and construction process

  • cost control and value engineering

  • risk analysis and management

  • quality management 

Development management

  • cash flow and funding agreements

  • establishing clear project objectives and project success criteria

  • assisting in the negotiation of development agreements with multiple stakeholders

  • Establishing handover and maintenance requirements

  • Project closure and post project evaluation
