CASE STUDY: High-Altitude Telecommunications Mast Dismantling

IDI Services Delivers Tandem Crane Operations for Lawrie Demolition on Mormond Hill

Client Profile

Lawrie Demolition, a leading specialist in industrial and infrastructure dismantling across Scotland, required the controlled dismantling of a 30-year-old telecommunications mast on Mormond Hill in Strichen, Aberdeenshire. As experts in complex demolition projects, Lawrie Demolition needed a lifting partner with tandem crane capabilities, experienced personnel, and the technical expertise to safely dismantle a substantial lattice tower structure in an exposed hilltop location—all whilst managing the unique challenges of working at significant elevation in a remote rural environment where weather conditions and access constraints demanded specialized planning and execution.

The Challenge

The Mormond Hill telecommunications mast dismantling presented multiple complex challenges that demanded IDI Services’ specialized tandem lifting expertise:

Site Location and Access Constraints

Mormond Hill summit location at significant elevation above sea level creating access and logistical challenges.
Remote hilltop site requiring transport of two large mobile cranes and support equipment up narrow rural access roads.
Exposed elevated position with spectacular views across Aberdeenshire also meaning exposure to strong winds and weather systems.
Limited working area on hilltop plateau restricting crane positioning options and equipment staging.
Ground conditions on exposed hillside requiring assessment and preparation for crane outrigger deployment.
Distance from IDI Services’ base and major transport routes necessitating comprehensive planning and mobilization logistics.

Telecommunications Mast Specifications

30-year-old lattice steel tower structure requiring sequential dismantling from top to bottom.
Substantial height demanding appropriate crane reach and lifting capacity at significant radius.
Heavy steel lattice sections weighing several tonnes requiring controlled lifting and load management.
Multiple telecommunications equipment installations including dishes, antennas, and mounting brackets requiring removal.
Structural integrity considerations as mast sections were disconnected and removed sequentially.
Historic tower potentially featuring bolted connections requiring assessment and disconnection procedures.

Tandem Lifting Requirements

Mast sections requiring two cranes working in perfect coordination due to weight distribution and structural configuration.
Simultaneous lifting operations demanding precise communication and synchronized movements between crane operators.
Load sharing calculations ensuring each crane handled appropriate weight distribution throughout lifts.
Coordinated positioning of both cranes to achieve optimal geometry for lifting tall lattice sections.
Sequential lifts requiring both cranes to reposition as dismantling progressed down the tower height.
Safety-critical operations where coordination failure could result in load imbalance or structural issues.

Environmental and Operational Factors

Exposed hilltop location subject to high winds requiring weather monitoring and operational wind speed limits.
Variable weather conditions typical of elevated Scottish locations affecting visibility, crane stability, and personnel safety.
Remote location limiting emergency response access and requiring comprehensive on-site safety provisions.
Coordination with telecommunications operators regarding service continuity and equipment decommissioning.
Environmental considerations for an elevated rural site with potential ecological sensitivities.
Public safety management ensuring hilltop area secured during demolition operations.
