Reference residence: a two-storey house, end to end

A demonstration from the platform's anonymised reference model, a two-storey reinforced concrete residence analysed, designed to BS 8110-1:1997, detailed and drawn by the platform. Not a client project.

Demonstration from the platform's anonymised reference model. The drawings and numbers on this page are the platform's own output; they are not a client project.

Role: Platform demonstration
Client: None: the platform's anonymised reference model
Location: Kenya (anonymised)
Year: 2026
Status: Demonstration
Structural system: Reinforced concrete frame, 2 × 2 bays of 4.5 × 4 m, 150 mm solid slabs on 200 × 450 beams and 300 × 200 columns, pad footings
Scope: Analysis, concrete design, detailing and the drawing set

Highlights

Two suspended floors on solid slabs whose loads reach the beams by BS 8110 clause 3.5.3.7
Pad footings sized at 150 kN/m² allowable bearing, with the stair and the wall strip footing as separate calculators
BS 8110-1:1997 Table 2.1 load combinations throughout
Every member designed and detailed, with the bar bending schedule and drawing set generated from the same model
Twelve drawing sheets, a 35-page design calculation report and a 31-page analysis report, each bound to the revision it came from

Foundation layout at ground level, nine pad footings on a two by two bay grid of 4.5 by 4.0 metres, sized from 850 by 850 to 1750 by 1750 millimetres — Foundation layout, level ground, scale 1:40 (sheet S-01)

Level 1 slab reinforcement plan with bottom bars B1 and B2 and top bars T1 and T2 marked over four 150 millimetre solid slab panels — Level 1 slab reinforcement, scale 1:25 (sheet S-31)

Elevations of beams B1-1 to B1-3 at level 1, 200 by 450 millimetres, with top and bottom bar marks and link zones over two 4.5 metre spans — Beam reinforcement details, level 1, scale 1:50 (sheet S-11)

Drawings

Level 1 slab layout with the typical 200 by 450 L-beam and T-beam sections, scales 1:40 and 1:20 (sheet S-02)

Typical pad footing section F-A1 with starter bars and the bottom mesh, scale 1:25 (sheet S-01)

Footing schedule, with the bars along L and B and the allowable bearing pressure of 150 kPa (sheet S-01)

Column schedule for C1 to C9, 200 by 300 columns with 4T12 main bars and T8 links at 125 (sheet S-21)

Stair flight 1 section, 150 millimetre waist, nine risers of 175 and goings of 250, T10 main bars and T8 distribution bars, scale 1:20 (sheet S-41)

Bar bending schedule to BS 8666:2005, the first of four sheets, 2302 bars and 2276 kg in all (sheet S-91)

The title block of every sheet, a generated draft to be checked and signed by the engineer

What this demonstration shows

The platform's reference residence is a small building chosen because every part of a typical Kenyan house passes through it: a frame of beams and columns, suspended solid slabs, a stair, pad footings under the columns and a strip footing under the walls. The model is anonymised: its dimensions and loads are representative, and it is not any client's building.

From this one model the platform runs the frame analysis, designs every beam, column, slab, stair and footing to BS 8110-1:1997, details the reinforcement to BS 8666, and produces the calculation report, the design calculation report, the bar bending schedule and the drawing set.

What it is not

It is not a client project and it carries no engineer's approval. The drawings and reports on this page are the platform's own output, shown so that a client or a reviewer can see what the firm's engineers work from before they apply their own judgement and sign.
