The beams will be strapped together using a roping method instead of the scaffolding proposed by Arup, in a bid to bring MSPs back into the debating chamber as soon as possible.
It is unclear whether or not Arup itself is behind the roping proposals. In March, after the original roof problem came to light, engineering consultancy Atkins was appointed to monitor Arup's work.
The Scottish Parliament's main hall has been closed off since early March after a beam swung loose from the roof of RMJM and Enric Miralles' Stirling Prize-winning building in Edinburgh.
Part of a two-phase repair programme, the temporary patch-up could mean business will be able to resume in the chamber within four weeks.
Steeplejack and rope-access specialist Pendrich has already begun 'installing the engineering solution' to the faults - understood to be caused by a defective bolt and socket.
However, the Scottish Parliament rejected the initial report findings because it felt the 'task of the erection and dismantling of [the] scaffolding' would be too time consuming.
Stage two of the works is expected to start as soon as the parliament's summer recess begins on 1 July.
