Specialist BIM consultancy for water, wastewater and civil infrastructure. ISO 19650-compliant. Delivered from the ground up by engineers who have built these assets — not just modelled them.
UK infrastructure clients face a persistent 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 — the demand for compliant, high-quality BIM delivery has never been greater.
Arangath was founded to serve that market directly. We bring together commercial rigour and 25 years of civil and environmental engineering expertise — delivering ISO 19650-compliant BIM services to UK water contractors and developers at the pace and quality their AMP8AMP8 — UK water sector investment cycle, 2025–2030 · £104bn committed projects demand.
Our delivery model is built for the AMP8AMP8 — UK water sector investment cycle, 2025–2030 · £104bn committed era. Efficient, technically authoritative, and structured to perform on the water, wastewater and civil infrastructure projects that matter most.
Multi-discipline federated model coordination across civil, structural, mechanical, electrical and process disciplines. Navisworks clash detection with full reporting and resolution workflows. 4D construction sequencing using Synchro — linking 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.
Project-specific 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 — structured for utility clients including Thames Water, Anglian, Severn Trent and United Utilities. Information 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 who need to meet utility client digital delivery requirements but lack 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, commercial, and structured around what your client actually requires — not theoretical BIM maturity models.
Construction drawing sets, as-built documentation, and record drawings produced directly from coordinated BIM models. Scan to BIM services converting point cloud survey data into intelligent Revit models. Quantity takeoff and material schedules extracted from federated models. Full project 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 understand what the model needs to do on site, not just on screen.
ISO 19650 Parts 1 and 2, UK BIM Framework, and utility client EIRs — including Thames Water, Anglian, Severn Trent and United Utilities — are rigorously interpreted and implemented.
Scope defined precisely. Deliverables costed transparently. 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 compromise on quality, compliance or turnaround.
Primary market. Serving contractors and developers delivering water, wastewater and civil infrastructure. AMP8AMP8 — UK water sector investment cycle, 2025–2030 · £104bn committed pipeline and public sector frameworks.
Secondary market. Strong infrastructure pipeline and established appetite for high-quality offshore BIM delivery. Expanding in 2026.
Longer horizon. Infrastructure investment bill driving BIM adoption. Strategic entry planned for 2027 via partnership or local representation.
Arangath was founded at the intersection of two disciplines that rarely meet: management consulting rigour and deep infrastructure engineering expertise.
Our technical foundation draws on over 25 years of civil and environmental engineering experience delivered 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 actually 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 exceptional engineering talent and a cost structure that allows us to price competitively without compromise on quality. Our client-facing operations are anchored in London.
Our technical foundation is built on 25 years of delivered infrastructure across water, civil and environmental engineering. The following projects represent the depth of engineering experience that informs every Arangath engagement. Illustrative BIM coordination models shown.
One of Kerala's longest bridges at nearly a kilometre in length, built across the Bharathapuzha river in southern India. The structure carries road traffic while also controlling the flow of water through the river via 70 built-in sluice gates — a dual-purpose design that cuts the driving distance between two of Kerala's major cities by 38km and brings irrigation water to 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 national 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 individual homes to a clean water supply 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 clean, 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 the Indian government's AMRUT urban infrastructure programme, the plant directly addresses chronic water scarcity across one of Kerala's largest urban areas.
