BIM at Eastwood & Partners
We are continually striving to further the services we offer to our clients and as such, have adopted Building Information Modelling (BIM) techniques on various projects to date.
We have been using Autodesk Revit (our 3D modelling tool of choice) for some time and have gained a wide range of experience in our own use of the software, as well as the integration of our BIM processes with those of other members of the design team. As such, we believe we are in a strong position to embrace the BIM concept as it develops and becomes more widely used throughout the construction industry and look forward to the huge array of benefits this will bring to both ourselves and those we work with.
We have worked to BIM level 2 on several projects to date, with level 3 capabilities should they be required by the Design Team.
These are a selection of 3D models created by Eastwood & Partners and reproduced with the kind permission of our clients.
This 3D model represents the main structure of the building, which is predominantly steel beams and columns with the 1st and 2nd floors made of concrete slabs on metal decking. The roof is made up of different layers, including metal decking fixed to cold rolled steel purlins.
The main feature of this building is the sloping, curved roof at one corner. This portion of the structure was difficult to model, due to the fact that steel beams can only be bent in one axis. So for each beam going round, they had a different plane at a different angle. The beams were faceted, level wise, to follow the curve/slope as closely as practicably possible and is covered by cladding to disguise that fact.
Eastwood & Partners were appointed to provide design services on this £3m new-build in the education sector. The proposed structure (2000 m²) will provide teaching and workshop facilities to the carpentry and joining, and painting and decorating departments.
From an early stage, it was highlighted that BIM techniques were to form a key driver within the Design Team. Our modelling process was fully coordinated with the Architect and this allowed us to iron out potential issues before reaching site.
This furnace project was carried out within an existing building, and over a 19 m diameter shaft. The proposed heavy industrial machinery also required low deflection limits, meaning tolerances had to be very closely followed throughout. As such, the adoption of a 3D modelling allowed us to fully coordinate our structural layout with the proposed machinery, as well as existing structure, as closely as possible.
This approach enabled us to identify complex clashes between various elements before the project reached site.
As part of our structural assessments we were also able to extract aspects of the steel frame into structural design software. This generated savings in both time and money, which would otherwise have been spent modelling the frame from scratch.
This model prepared by Eastwood & Partners shows the additional buildings that were required to add new processes to a large cement works.
Conveyors and varying levels were coordinated and visualised using the 3D environment. In-depth liaison with the client and manufacturers of specialised equipment was required using this technology to ensure critical components functioned correctly.
Eastwood & Partners were commissioned to prepare full working drawings for the structural alteration to an existing lecture room to create a new gymnasium.
The design involved removing a section of the existing roof and construction of a new higher roof above with exposed glulam timber beams and timber framed walls.
The construction work started on site in December 2014 and is expected to be completed by May 2015.
Eastwood & Partners designed a new steel shell cement powder storage silo for a distribution hub. The 3D model was built in Revit, and was used to prepare structural general arrangement drawings.
Eastwood & Partners have the capability to export from Revit 3D geometric models to generate complex finite element models for analysis and design.
Eastwood & Partners prepared Concept Feasibility Models for new storage/distribution facilities in South Wales. The structural form is steel portal frames and reinforced concrete pad foundations with perimeter strip footings.
Also included within the remit was a requirement for loading areas within restricted access zones, subsequently resolved with a series of ramps incorporating dock levellers.
The conversion of an existing coal bunker into a PFA flat store. The original building comprised of vertical concrete walls spanning horizontally between vertical concrete cantilever columns.
A cladded steel frame is mounted off the concrete walls/columns which encloses the existing structure.
The conversion to a PFA flat store involved the strengthening of the cantilever concrete columns with raking steel props mounted to the top of the columns and fixed to thrust blocks at their base.
New gable steelwork was provided to each end of the existing bunker to fully enclose the store and support the filtration units and provide gantry access.
Eastwood & Partners worked closely with our client on this project and this relationship was enhanced by the delivery of working 3D models as discussion points.
This allowed us to develop a solution which met the client’s requirements, while also negotiating a congested site, with numerous existing underground services as well as coordination with existing rail tracks at ground level.
