Rydens Enterprise School & Sixth Form College

undertook a huge redevelopment of their site to

create a state-of-the-art facility to deliver 21st

Century education, consisting of seven buildings.

TDS Midlands were on hand to design & detail the

complexed 385 tonne steelwork frame.

The geometry of the architectural design presented

the largest challenge in designing the corresponding

geometry of the steelwork. In particular, fulfilling

the complex asymmetrical pyramid shape of the

library roof used a considerable amount of detailing

resource. Careful consideration was taken when

detailing the complex connections as we had to make

sure the connections would be structurally acceptable

together with ensuring that the fabricator would be

able to manufacture and erect the structure.

The Project

Tekla’s ability to import IFC models issued by the

design team was invaluable when setting out the

complex geometry of the steelwork frame. The

design of the structure was modified throughout the

duration of the project. Importing the amended IFC

models allowed us to overlay them onto our model

and alter our steel frame accordingly. Due to the size

of the project, phasing and lotting was imperative

when issuing steelwork for manufacture and erection.

Tekla allowed us to segregate areas of the structure in

approximately 25 tonne lots in order to ensure each

lot was deliverable to site in one single visit.

From fabrication drawing point of view, this was one of the most

challenging projects that TDS have undertaken, the most complex

assembly drawings used up to 4 hours of drawing office time.

Without the power of Tekla, the detailing of the assembly drawings

would have taken considerably longer, allowing us to complete the

fabrication drawings in a cost efficient time scale.

Throughout the project, Tekla’s ability to generate 3D BIM models in

order to issue to the Design Team to review has been a considerable

advantage to all contractors involved. Architects were able to

review the aesthetics of the steelwork, Engineers could interrogate

connections and steelwork arrangements and the fabricator &

main contractor used the 3D models to plan fabrication schedules

and erection techniques. Together with Tekla BIMSight, the use

of Snapshots were used when raising queries to the design team.

Creating a visual of the query in question enabled us to translate

our question to the design team in a more specific manner. The

connection design received from the engineer was generated in a 2D

format. In order to translate the 2D connection design into a complex

3D geometry format, we had to issue a number of queries regarding

geometrics and buildability.
