Technological Innovations

Loose bar schedules require rebar fixers. It is much morecost effective to use special prefabricated meshes which are predominant on ourdrawings. These are just a couple of examples where we drive down materialcosts and reduce the spending required by our clients.

Basement formation process involves gradual excavation andpropping of the house. Cantilevered retaining walls are cast to support theweight of the house above and to resist the lateral earth pressures.

A complete basement acts as one unit resisting the soilforces. In the excavation phase the stability of the area worked on is ofupmost importance. Temporary propping is required until cantilevered retainingwalls can be inserted. These are inherently stable and individually resist theground forces.

Segmental lifts and sectional underpinning:  Croft Structural + Civil have received researchand development rebates for their work in this area.  Their skill in knowing how and where tochange from normal underpinning to specialist sectional and top down methods isessential for completing an economic and safe build.

Croft Structural Engineers leads with the latesttechnological innovations. We have invested heavily in design software to helpsupport our engineers in providing the appropriate design outcomes. Thesetechnologies allow us to determine the loads of adjacent buildings moreaccurately, resulting in using lighter reinforcement.

Ground Movement Assessments

Croft can undertake ground movement assessments on thesoils. These provide predictions on the level of movement that may occur to theproperty and also the surround areas. Over time these have become more complex,Croft uses the skills of specialist Chartered Geologist to provide this levelof information. The level of movement is related back to strains within thebuilding, and these are equated to damage categories under the Burland Scale.Typically, movements between slight to very slight are predicted. However, inour experience which is backed up by site monitoring, the level of movement hasbeen less that the predicted movement.

The staff at Croft are a clever bunch and have worked outhow the Geologist undertake their assessments and for simple conditions canundertake movement assessments. We consider movement in line with the guidanceof CIRIA’s C720 and also includes the heave of the clay that occurs when thesoil is excavated. Most Structural Engineers will pass the ground movementassessment solely over to a Geologist, on small projects this can be anexpensive option. Croft has written software to allow for initial Ground MovementAssessments to be undertaken without the need for specialist GeotechnicalEngineers.

What are GMAs?

GMA = Ground Movement Assessment

Give theoretical prediction on how ground near excavationswill move

When? – Planning Party wall responses, especially nearlisted buildings

Where? – Carried out on excavations near properties thatmight be affected

Our Design Process

Croft Structural + Civil  play an integral part in providing solutionsfor day-to-day temporary works and a sensible approach is always offered in ourdesign. Our knowledge of structural engineering and construction methodologyhas provided our clients with alternative design and construction processes.These have resulted in both cost and time savings on contracts: Shot Cretewalls, integration of permanent and temporary support are some techniques used.

It is essential that the stability of a structure ismaintained throughout the construction process, and this is reflected in ourdesigns. We are totally committed to creating a safe working environment on allour projects. The majority of basement construction requires issuing a PartyWall Notice to adjoining owners. Our expert knowledge of the Party Wall Actensures we are the first point of contact for Party Wall Surveyors in providingreliable, specialist design reviews.

Croft’s professional and friendly approach, combined withour cost effectiveness, gives us the enviable reputation for repeat work.Contractors often approach us at tender stage to look at redesigning basementsto reduce the costs and win them the project. You will be getting the bestpossible value for money when you choose Croft Structural Engineers for yourbasement conversion.

Our service ranges from the initial planning stage, with aBasement Impact Assessment or a Construction Method Statement and up until theconstruction works are completed. Croft is available for site visits to inspectthe works as they are progressing on site and provide valuable guidance duringthe construction stage. We work closely with the client’s chosen contractor toallow for a safe and comfortable construction sequence and providing a cleartemporary works design sequence and drawings.

Our Projects

Delivering projects at varying scale

We understand that a property is a large investment, which is why we work on an ethos of providing a personal approach to all projects. Whether small or large, when appointing Croft you will be assigned your own engineer to personally lead through your construction process every step of the way. We have the resources to deliver projects within a framework that suits you.
