INDEPENDENT CONSULTANT • TELECOM & DIGITAL INFRASTRUCTURE • TSHWANE, GAUTENG, SA
Telecoms, engineering & digital infrastructure
Thirty years’ leadership in telecom infrastructure, mechanical engineering, and digital transformation—national tower and 5G programmes, IoT and Digital Twin deployments, fabrication and pipeline systems, and turnkey governance from boardroom to field execution.
Ipenga Consulting delivers strategic and technical advisory across telecommunications infrastructure, IoT and digital transformation, mechanical and industrial engineering, HSE and quality assurance, and large-scale programme governance. Engagements combine board-level clarity with field-proven execution—supporting operators, municipalities, transport and security clients, and industrial asset owners who operate in regulated, high-consequence environments.
Carl von Graszouw brings more than thirty years of multinational experience across twenty-two African countries and select international markets, including national tower and 5G modernisation programmes, Digital Twin and cluster optimisation initiatives (notably R75M+ Capex savings recognised with the Vodacom CEO Award for Technology & Innovation), and independent consulting since 2024 with a growing portfolio of public- and private-sector clients.
Core consulting areas include:
Typical mandates span national and regional telecom programmes, public-sector and critical-infrastructure operators, security and transport clients, and heavy industrial asset owners—always scoped to your operating context, risk appetite, and governance cadence.
Telecommunications & digital infrastructure
Strategic and technical advisory for tower and rooftop portfolios, 5G/4G modernisation, power and hybrid energy systems, co-location and capacity management, and national upgrade programmes. Digital Twin, drone/laser and GIS-based asset intelligence; IoT integration (IoT.nxt, Sigfox, LoRa, BLE); ICASA, SANS, and structural compliance aligned to TIA-222 and local standards—supporting operators and service providers who must defend uptime, safety, and regulatory posture at scale.
IoT, security & operational risk
Design and assessment of IoT and security architectures for critical infrastructure and distributed operations—risk management frameworks, control-room and perimeter logic, and integration with operational data. Independent consulting experience across transport, security, municipal, and infrastructure clients, with HSE and QC audits aimed at reducing operational exposure while keeping systems auditable and maintainable.
Mechanical, structural & industrial engineering
Fabrication and workshop oversight (high-tonnage capacity environments), bulk material handling and transfer chutes, DEM and flow optimisation, structural fabrication QA, and NDT coordination. Support for mining, metals, and heavy industrial clients—linking mechanical integrity, maintenance strategy, and delivery discipline on brownfield and greenfield work.
HSE, quality & regulatory assurance
Programmes aligned to ISO 45001 and ISO 9001 expectations: HIRA and JSA development, permit-to-work and rooftop/fall-arrest compliance for telecoms, welding quality to AWS D1.1 / ASME IX / ISO 3834, and regulatory alignment with ICASA, OHS Act, and applicable SANS codes—so safety and quality evidence stand up to internal audit and external scrutiny.
Programme governance & digital transformation
Leadership and advisory on large capex/OPEX programmes—strategic oversight, stakeholder and vendor governance, budgeting and forecasting, KPI and milestone control, and digital transformation roadmaps including enterprise data integration and O&M digitisation. Suited to organisations modernising national footprints while keeping financial and delivery discipline visible to executives and boards.
Pipeline systems & asset integrity
High- and low-pressure pipeline strategy and rehabilitation: steel, HDPE, and composite systems; trenchless technologies including lining and rehabilitation methods; civil route preparation and commissioning support. Draws on cross-border project delivery and major pipeline experience for mining, water, and industrial clients who require integrity, schedule certainty, and field-credible engineering judgement.
