Specialist BIM consultancy for water, wastewater and civil infrastructure. ISO 19650-compliant, delivered by engineers who built these assets — not modelled them.
UK infrastructure clients face a shortage of senior BIM expertise. Projects slip. Coordination fails. Rework costs mount. With £104bn committed to water and wastewater infrastructure through AMP8AMP8 — UK water sector investment cycle, 2025–2030 · £104bn committed — more than double the previous investment cycle — demand for compliant, high-quality BIM delivery has never been greater.
Arangath was founded to serve that market directly. We combine commercial rigour with 25 years of civil and environmental engineering expertise, delivering ISO 19650-compliant BIM services at the pace and quality AMP8AMP8 — UK water sector investment cycle, 2025–2030 · £104bn committed projects demand.
Built for the AMP8AMP8 — UK water sector investment cycle, 2025–2030 · £104bn committed era — efficient, authoritative, and structured for the water, wastewater and civil infrastructure projects that matter most.
Federated model coordination across civil, structural, mechanical, electrical and process disciplines. Navisworks clash detection with full reporting and resolution workflows. 4D sequencing using Synchro links programme to model, so contractors can rehearse and de-risk methodology before a single spade breaks ground. Standard practice on AMP8AMP8 — UK water sector investment cycle, 2025–2030 · £104bn committed water and wastewater contracts.
BIM Execution Plans responding directly to Employer's Information Requirements. Common Data Environment setup and administration on ACC, BIM360, or ProjectWise. Asset Information Requirement planning and AIM handover, with BEPs built to the published Employer's Information Requirements and asset-information standards of the UK's major water companies — Thames Water, Anglian, Severn Trent, United Utilities. Delivery milestones mapped to data drops, built to pass client review from day one.
For Tier 2 contractors entering AMP8AMP8 — UK water sector investment cycle, 2025–2030 · £104bn committed frameworks without in-house BIM capability. We set up your digital delivery workflows, respond to EIRs on your behalf, establish CDE environments, and onboard your project teams. Practical and commercial, structured around what your client requires — not theoretical BIM maturity models.
Construction drawing sets, as-built documentation and record drawings produced directly from coordinated BIM models. Scan to BIM converts point cloud survey data into intelligent Revit models. Quantity takeoff and material schedules extracted from federated models. Documentation packages meeting UK contractor and utility client submission requirements.
Our technical advisory comes from 25 years of contracting on water and wastewater infrastructure, not from a BIM software background. We know what the model needs to do on site, not just on screen.
ISO 19650 Parts 1 and 2, the UK BIM Framework, and BEPs built to the published Employer's Information Requirements and asset-information standards of the UK's major water companies — Thames Water, Anglian, Severn Trent, United Utilities — are rigorously interpreted and implemented.
Scope defined. Deliverables costed. No scope creep, no ambiguity. Structured engagements from first brief to AIM handover.
Senior-grade output at a cost point UK-only firms cannot match. Our delivery model closes the AMP8AMP8 — UK water sector investment cycle, 2025–2030 · £104bn committed skills gap without compromising quality, compliance or turnaround.
Primary market, serving contractors and developers across water, wastewater and civil infrastructure — AMP8AMP8 — UK water sector investment cycle, 2025–2030 · £104bn committed pipeline and public sector frameworks.
Long-term vision market, with a strong infrastructure pipeline and appetite for offshore BIM delivery — a natural extension once our UK water specialism is established.
Longer horizon. Sustained infrastructure investment continuing to drive BIM adoption — a market we are watching for potential entry via partnership or local representation.
Arangath was founded at the intersection of two disciplines that rarely meet: consulting rigour and infrastructure engineering expertise.
Our technical foundation draws on 25 years of civil and environmental engineering experience across Kerala and Andhra Pradesh — water treatment, wastewater, rural supply networks, and large-scale civil contracts. That is not a software background. It is a track record of building the assets we now model.
We understand how infrastructure clients think commercially, how contracts are structured, and what BIM compliance requires on a live project. That combination — uncommon in the BIM market — is our foundation.
Our delivery operation is based in India, giving us access to strong engineering talent and a cost structure that lets us price competitively without compromising quality. Our client-facing operations are anchored in London.
Our technical foundation is built on 25 years of infrastructure delivery across water, civil and environmental engineering. These projects reflect the depth of experience behind every Arangath engagement. Illustrative BIM coordination models shown.
One of Kerala's longest bridges at nearly a kilometre, built across the Bharathapuzha river in southern India. It carries road traffic while controlling the flow of water through 70 sluice gates — a dual-purpose design that cuts the driving distance between two of Kerala's major cities by 38km and irrigates thousands of hectares of farmland. A complex civil and hydraulic engineering contract requiring precise coordination between road, bridge and water management systems.
Drinking water infrastructure delivered under India's Jal Jeevan Mission — a government programme bringing piped clean water to every rural household across the country. Works in Kollam district included laying underground water mains, building pumping stations and elevated storage tanks, drilling tube wells, and connecting thousands of homes to clean water for the first time. A community-scale civil engineering contract with direct impact on public health.
A large-scale drinking water treatment facility built to serve Kollam city and surrounding communities in southern Kerala — processing 100 million litres of raw water every day into safe drinking water. The plant takes water from source, aerates it to remove odours, passes it through three large circular settling tanks, filters it through 24 filter beds, and disinfects it before pumping it through a new trunk main to the city. Delivered under India's AMRUT programme, addressing chronic water scarcity across one of Kerala's largest urban areas.
