One of our consultants will visit you at home, at your convenience, to discuss your proposed project and offer you free advice. A short survey is completed and your consultant will make some sketches and take notes related to your requirements.
A free, fixed price (subject to survey results) quotation will be provided within five working days, although the more complex projects may require more time.
In the meantime, you are welcome to visit one or more of our completed projects and discuss our services with our past clients. This will give you the opportunity to see the results of our work and appreciate the high standard of finish. View our testimonials to see what a selection of our clients have to say.
On your approval of our quotation, the design (link to next page) stage begins.
The design stage begins with the location of light wells, access points and skips and all the services you need are identified and marked out.
The architectural survey, which translates the design onto a set of proposed drawings, is completed. These drawings are submitted, by us, to your local planning authority, for approval.
The structural and geotechnical surveys are undertaken and a structural layout is determined. The types of soil are identified and the foundation details are recorded. Any detection of contamination, water levels and/or complications involving gas, large or irregular foundations or the possibility of compromising structural integrity will be noted and solutions discussed with you.
The final phase of this stage is the construction method statement, which we will present to your local authority. All the information is collated and we then submit the application to your local planning department. During this time our contractor visits the site to discuss the methodology and design constraints and a drainage plan is drawn up and then approved by an independent waterproofing specialist. The construction (link to next page) stage begins on receipt of planning approval and on completion of the party wall process.
Site preparations take place, following the pre-start meeting, endorsement of contracts, and receipt of 5% of the total cost of your project.
A payment schedule, which matches the length of the scope of works, is presented to you and includes a weekly payment plan, which is paid, in arrears, to our contractor at the end of each stage of the agreed works. Your project coordinator will monitor and assess the works, prior to payments, to ensure that targets have been met.
The preparations for the project include setting up the hoarding, installation of temporary services, breaking through, and setting up the conveyor belt.
Parking suspensions, which we have applied for in advance, are verified.
The structural works start with the excavation, the setting up of temporary supports, underpinning, installation of steel works and reinforcement, setting up drainage, casting of the concrete slab and the waterproofing.
We utilize Delta (link to Delta website) membranes, which are guaranteed (link) for 30 years and are inspected by an independent approved specialist. We select a membrane that is compatible with the substrate in your property and it is fixed in place mechanically, avoiding binding. The studded structure allows the dampness to disperse and the surfaces of the wall and floor take the damp load. On the majority of projects, a twin sump system is installed. The water ingress, which develops behind the studded membrane, is channelled into a pump chamber, which features a self-contained pump, delivering the water to ground level, and it is then disposed of through the main drainage system. The system also features a back- up pump, which takes over; in the event of a primary pump failure and both pumps provide back-up in the event of a power cut. The installation of the Delta membrane is guaranteed for ten years.
We estimate the duration of the structural phase to be from 16 to 24 weeks, although complex works may take longer. During this time we arrange for the building control officer, attached to your local authority, to oversee all stages of the works.
The final stages, following completion of the structural work, commence, when our in-house structural engineer signs off. The basement is then ready for the fit-out (link to next page)
We estimate the duration of a basement fit-out to be from 8 to 12 weeks, although the more complex projects may take longer. All the partition walls, ceilings and floors are placed to make the space habitable. The walk- on- glass or metal grills over the light wells are installed, allowing natural light to flood the area, the first fix electrical and plumbing stages are completed and the staircase is installed.
To ensure that our clients are completely satisfied, the fit-out is completed prior to settlement of the final payment. The building control officer is invited to inspect the project and to provide a certificate of approval, which is then presented to you.
Your project is complete and we then present you with your guarantees (link to next page).
