Abstract

fetched live from OpenAlex

This paper presents a case study of the construction of a partially pre-stressed multi-storey office block in Adelaide, Australia. The designers and construction managers faced numerous issues involving the construction speed and performance of the nine storey building, in particular the performance of the two-way partially pre-stressed suspended slabs. The planned construction period was an absolute minimum due to a contract for early occupancy and high daily costs of construction equipment. Excessive deflections of the 9.6 m × 8.4 m × 200 mm thick slabs were a concern for this fast-track construction. This situation created some significant issues to ensure satisfactory construction speed and acceptable deflection levels. This paper discusses these issues while also explaining and documenting the steps taken to obtain the final solution. A large collection of data from the construction process is presented. An emphasis is placed on the material properties of the concrete slabs, namely compressive strength (fc) and modulus of elasticity (Ec) development over time, due to their direct effect on the construction timeline. The effects of concrete curing conditions on material property development are also addressed. Lastly the outcomes and performance of the slabs, namely construction time and slab deformations, are presented.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
