The challenges of the main pitch at Murrayfield Stadium have been well documented this year with the entire surface being replaced, from the bottom up, over the last two months.
The playing surface has been moved one and a half metres nearer to the west stand, all soil replaced and over the last two weeks, the new artificial part of the pitch has been 'stitched' into place. This has involved three outsize 'sewing' machines, using enough green plastic thread to wrap around the world twice, in a 24-hour seven-day-week operation manned by two technical crews from contractors Desso Sports Master in Holland.
Work will pause, on completion of the artificial element, for next week's One Direction concert (3 June), after which the grass seed part of the hybrid pitch will be sewn with the surface completed in good time for the visit of Celtic FC for their Champion's League qualifier in July.
Our video shows what's been happening to the pitch, with the machines in action, and interviews with Scottish Rugby head groundsman Jim Dawson and Desso Sports Master.
