    CJ Construction’s first Mardon Park scheme: design and delivery notes for project teams

    First reported on The Construction Index

    30 Second Briefing

    CJ Construction (Wales) is delivering its first direct commercial development at Mardon Park, Baglan, converting 1.37 acres of brownfield land within the Port Talbot Waterfront Enterprise Zone into more than 20,000 sq ft of speculative commercial space. Backed by a £2.35m package from the Development Bank of Wales, including a £1.37m grant and a £980,000 Wales Commercial Property Fund loan, the build is scheduled for roughly six months. Units are being designed for flexible occupation, either as a single large tenancy or subdivided for multiple smaller businesses, creating work for local subcontractors and suppliers.

    Technical Brief

    • Funding stack comprises a £1.37m grant plus a £980,000 Wales Commercial Property Fund loan.
    • Development is being delivered by CJ Construction (Wales) as its first self-developed commercial scheme.
    • Site lies within the Port Talbot Waterfront Enterprise Zone, implying enhanced planning and fiscal incentives.
    • Project launch follows a July 2024 self-funded MBO by Russell Jones and Alex Holland.
    • Founder Chris Jones remains in an advisory capacity, retaining continuity of construction and procurement know-how.
    • CJ Construction currently employs 32 staff with an annual turnover of nearly £5m, indicating SME delivery capacity.
    • Contractor brings two decades’ experience as principal contractor on commercial and residential schemes across South Wales.

    Our Take

    Given CJ Construction’s circa £5m annual turnover and 32‑person headcount, taking on a six‑month commercial development as principal developer marks a step up the value chain from pure contracting, a pattern seen in other regional contractors that have recently completed management buyouts and are seeking higher-margin work.

    Strabag’s Pfaffensteig Tunnel contract: design and delivery notes for rail engineers

    Strabag and Group company Züblin have secured the design-and-build structural works for the ABS Gäubahn Nord/Pfaffensteig Tunnel in south-west Germany, centred on an 11km twin-bore rail tunnel linking Stuttgart Airport station directly to the Gäubahn line towards Switzerland. About 9.8km will be driven by two TBMs, with conventional tunnelling for the A8 motorway undercrossing and airport connection, plus a 240m cut-and-cover section, retaining structures, railway underpasses and a grade-separated crossing. A 3km surface section will be upgraded and partially realigned for 200km/h operation, delivered under an integrated project delivery model with Ed. Züblin, Wayss & Freytag and Strabag AG sharing tunnelling, structural and earthworks packages.

    National Grid TBM under the Thames: tunnelling design and risk notes for engineers

    A 271.5‑tonne Herrenknecht Mixshield TBM, Caroline, has started driving a 2.2km electricity cable tunnel with a 4m internal diameter beneath the River Thames in Essex for National Grid’s Grain to Tilbury project, delivered by the Ferrovial BEMO joint venture. The drive will pass through variable Thames estuary ground conditions between 35m‑deep launch and reception shafts of 15m and 12m diameter, with tunnelling continuing into 2026 and overall scheme completion targeted for 2029. The new tunnel will replace the 1969 Thames Cable Tunnel and carry new high‑voltage circuits between Grain and Tilbury substations.

    Panama Canal Mixshield undercrossing: design and tunnelling lessons for engineers

    A 13.46m diameter Herrenknecht Mixshield TBM has broken through into the future Balboa station on Panama Metro Line 3 after completing the first-ever TBM undercrossing of the Panama Canal at depths exceeding 60m below sea level. The 5,600kW, 26,616kNm machine, fitted with an accessible cutterhead and more than 4,500 sensors linked via the Herrenknecht.Connected platform, has achieved peak advance of 150 segment rings (about 300m) per month through mixed sandstone, tuff, breccias and basalt. Around 1.5km of the 4.5km twin-track tunnel remains to final breakthrough.
