Your Project
Perhaps you want to improve your home or see an opportunity to increase the value of one of your properties.
99 Structural Engineers are a Kensington-based structural engineering practice. We serve local residents and businesses throughout Kensington and Chelsea as well as the surrounding areas of West London.
We provide structural engineering consultancy across our three sectors of Residential, Commercial and Culture.
Over many years we have built trusted collaborations with many specialists and experts. So we can carefully curate a bespoke team for your project giving you access to the very best people in the industry.
Our Process
We can be appointed for different stages of the project depending on your needs. Some examples are given below or please feel free to call to discuss alternatives.
RIBA Stage 1 – Feasibility
This is advice given pre-purchase or before significant capital is committed. It typically involves a report after a site visit or it could be as simple as a discussion on the phone.
For example a Client wished to convert a property they owned (pictured) into an HMO and reconfigure each floor to improve the layout and increase its appeal. We visited the property and provided a report identifying which walls were structural and what quantum of structural work would be required to achieve the intended layout at each floor.
RIBA Stage 2/3 – Documents for Planning
This process is normally led by an Architect or a Planning Consultant. You will probably need our assistance if the property is listed or the construction will involve excavation for example to create a new basement. You may also choose to appoint us to check the viability of a proposal before the planning process begins. We may be able to reduce your construction costs if consulted at this stage.
We typically visit the property and if necessary review opening up works. We would then produce sketches showing the likely structure that would be required with estimated structural sizes for costing. For changes to listed buildings or for excavation our deliverable is a report to the Planners, signed by a Chartered Engineer and Member of the Institution of Civil Engineers (CEng MICE).
RIBA Stage 3/4 – Produce Documents for Tender and Calculations for Building Control
You will need our assistance if the structure is being altered or new structure proposed. We typically work closely with the architect to coordinate the design.
Our deliverable is a series of drawings and sketches. These provide the information the contractor needs to quote and then build the project correctly.
We also produce a package of calculations for Building Control. These are to demonstrate that the proposed structure is adequate and complies with the relevant Building Regulations, British Standards and Eurocodes.
RIBA Stage 5 – Construction
We recommend that we are appointed to inspect during construction as a helpful safety check that there are no significant deviations from our design.
It is common that we are appointed to review some of the contractor’s technical proposals such as temporary works, steel connection designs and concrete reinforcement drawings.
There may also be changes made during construction in response to the existing building or requested by the client or contractor which we can be appointed to re-design.
