Progress Update, August 2024
Issued 14th August, 2024
Derek Walsh, contracts manager for BAM UK & Ireland, CTLR’s main contractor explained, “There are three stich segments which tie the structure together upon completion. The first was poured on July 23rd and is located at the east end of the structure.
“The second and third stitches are carefully constructed following a precise construction sequence; this week, we’ve carried out the internal kentledge concrete pour on the east section of the bridge, and this will be followed by alignment checks, stressing work, and the second stitch. The third and final west end stitch will be completed early in September 2024.”
Jillian Ferguson, Roads & Infrastructure Manager, commented, “We have made good progress this summer and I’m pleased to have welcomed the First Minister and our local elected representatives to witness the efforts of the team. These final few weeks mark a significant milestone within the project, and I am delighted to report that structural work on Destiny Bridge is expected to complete mid-September.”
Destiny Bridge
Both the east abutment receiving segment (EP-SS15) and the west abutment receiving segment (WP-SS16) are now complete.
The construction of the balanced cantilever reinforced concrete bridge deck segments has continued with all fifty-four segments now complete. The careful construction sequence used has ensured perfect balance is maintained throughout the process.
In addition, the first (EP-SS14) of three the stitch segments is complete and the bridge superstructure (deck) is scheduled for completion by mid-September 2024. (See central stitch process below).
New Kingsway
Several key elements including traffic signs, street lighting, vehicle safety barriers, and landscaping are all nearing completion between the A93 and A94 roundabouts. Surfacing has also progressed well. Remaining works on signage and verge finishes will complete next period.
The Green Bridge at Highfield is complete with only final touches to landscaping to come. This important connection between the new road and Highfield Woods serves as a crossing for local wildlife, and active travel users.
The Living Bench public artwork installation is also complete and sits atop the Green Bridge. Work on the artwork mural under the bridge will be complete by end of August 2024.
A9
The new A9 alignment is fully established and working well for drivers, and ancillary works such as bus-bays, footpaths, and accommodation works are completed.
The earthworks and drainage along the old A9 route continue, but drainage for the new Park-and-Choose area is now complete.
Finishing works on the A9 overbridge superstructure, including kerbing, ducting and hard landscaping, and surfacing works on adjacent roundabouts are also complete.
Work on the reinforced earth approach embankment, connecting the new A9 junction to Destiny bridge, continues. The Denmarkfield Access Portal precast units have been installed and the connecting reinforced earth panel retaining wall has commenced. This structure, when completed, will maintain through-access for local properties, as well as cyclists and pedestrians. Active travellers have been temporarily diverted from the A9 onto the existing riverside core path, enabling works to progress here safely.
Central Stitch Process
First stitch, segment EP-SS14 which is located on the east end of the structure.
- This was poured on 23 July 2024
Second stitch, segment WP-MS15 is centrally located on structure.
- This is carefully constructed following a precise construction sequence
- Presently, all the east part of the structure is stressed using post tensioning cables
- Followed closely by an internal kentledge concrete pour which is scheduled for early w/c 12 August 2024.
- This facilitate the installation of alignment device between the two opposing decks (west WP-MS14 / east EP-MS14), the alignment device is required to ensure that both decks are at the same level
- Upon completion of the alignment device installation, the stitch can be completed – scheduled for completion during w/c 19 August 2024
Third (final) stitch, segment WP-SS15 which is located on the west end of the structure.
- Like the second stitch, this is carefully constructed following a precise construction sequence
- Stress the main deck continuity tendons (segments WP-MS06 through to EP-MS06)
- Carefully remove the western pier temporary prop using hydraulic jacks
- As above, place alignment device between the two opposing decks (WP-SS14 & WP-SS16)
- Upon completion of the alignment device installation, the stitch can be completed - scheduled for completion during w/c 09 September 2024
