CBI-Basements offers a full range of services. Prior to construction or under an existing building, we can provide:
·Waterproofing and leak sealing
·Drainage and pumping
·Underpinning and piling
·Soil/ground surveys
·Reinforced concrete and masonry
·General building
·High quality finishing and fit-out works
Surveying
At the onset of each new project, our experienced surveyors analyze the material and structure of your building. They can then provide advice regarding basement size, practicality, and design. You choose the modifications that are best for you – from specialized detailing to finishing. A written estimate, subdivided into design, planning, exploratory, structural and waterproofing, and fit out and finishing sections are provided. Throughout the project we keep our preliminary estimates in mind. The same surveyor will be associated with your project throughout the building process, and you will be advised of any changes in projected costs.
Design
CBI-Basements is one of the only true “design and build” companies in the United States. By directly managing your construction project from inception to completion we are able to ensure quality and keep your costs at a minimum.
Project Management
Our leaders are the envy of other construction companies. Dedicated team members, including structural foremen, fit-out foremen, and project managers, work conscientiously to build the basement of your dreams. One of our project managers will begin working closely with you during the design stages, and they will be your liaison for the duration of the project. They will work with the rest of the team to make sure that each stage is accomplished promptly and within budget. Once construction is completed, the project manager will help you select floor finishes, wall finishes, specialist joinery, and ironmongery. He can also help coordinate sub-contractors such as audio-visual or
alarm/security installations if desired.
Health and Safety
At CBI- Basements we believe that a job is not done right if it is not done safely. We have dedicated health and safety managers, and regularly send our employees and managers to safety training courses. Project sites are audited to ensure compliance with local regulations.
Structural Works
We are pioneers in the basement construction industry. Our innovative engineering and underpinning solutions allow us to maximize space and minimize cost. Past clients have even elected to install basements below gardens and driveways as well as sub-basements for swimming pools, plant rooms, wine cellars, and storage. We can dig under a specific area, under the entire house, or beyond the borders of the aboveground structure. You choose how much additional space you want. Usually we are able to excavate under your property while you continue living normally in your home. The size and flexibility of our structural teams ensures that we are able to take on any project and complete it to our customers’ exact specifications.
The Pre-Construction Process
·An initial discussion is held via phone/email regarding feasibility of location and budget.
·A preliminary appointment is set up at your convenience, and a proposed budget is provided. (10 working days)
·After an offer has been accepted, a comprehensive survey of your property is undertaken and a full set of plans and drawings is produced, all of which must meet your approval. (10 – 15 working days)
·The building regulation drawings are submitted to your local planning authority for authorization. (8 – 12 weeks maximum)
·While waiting for approval we conduct onsite exploratory trials and tests, generating information that will be used in the structural design. Additionally, either CBI-Basements or a sub-contractor (you choose) will conduct a party wall survey.
·After approval a pre-commencement meeting is held to discuss logistics and to set a start date. This ensures that there are no surprises during the project and that all construction proceeds in a safe and orderly manner.
