    Grant Plant Hire Ltd

    United Kingdom

    Grant Plant Hire Ltd (GPHL) is based near Penrith in the north of England close to the M6 and A66. GPHL has the highest of standards when it comes to the delivery of construction projects throughout Scotland and Northern England. The time-served expertise within our team gives us the ability to not only focus on the critical path but all the ancillary aspects of the job. We take pride in offering a partnered approach with our clients in order to achieve the best outcome with the minimum of delay. As well as traditional civil engineering works, GPHL specialisms include: Steel piled cofferdams In-river working Pipeline/trunk main installation Deep drainage Hydro electric schemes Tidal works Our latest projects Water mains: Currently we are engaged on Northumbrian Water’s County Durham and Tees Valley Pipeline, it is designed to improve water quality and increase resilience and operability within the Tees Network. The pipeline will replace existing portable water mains across the North East of England. GPHL are installing over 11 km of new steel welded main, completing works at the Whorley Strategic Connection including three number cast in situ underground tanks and tying in both the new inlet and twin outlet pipework to the existing reservoir. Hydro electric: GPHL have recently completed all the civil engineering works on a pioneering new type of hydro energy generation scheme at Whiteadder Reservoir, East Lothian for Scottish Water as part of its work to reduce carbon emissions. The hydro energy generation scheme is fed by a siphon and is believed to be the first of its type in Europe.  The scheme will enable Scottish Water to generate green energy while accurately controlling the level of the reservoir during seasonal fluctuations in weather. The siphon technology in the project allows Scottish Water to draw water up through the intake and over the top of the dam which then runs down through the siphon, through the hydro turbine, and back to the natural environment. Flood alleviation: GPHL are also currently subcontracted to Volker Stevin on the Flood Risk management Scheme in Appleby, for the Environment Agency. The project involves the installation of a new flood relief pumping station and installation of a new stretch of culvert diverting an existing culvert to the pumping station. A new rising main will outfall into the River Eden. The scheme is known as Appleby Town Centre Flood Risk Management Scheme (FRMS) and aims to reduce flooding caused by surcharging of the Doomgate Culvert which is designated as a main river and is a tributary of the River Eden.

    Greenbank Group logo

    Greenbank Group

    United Kingdom

    A specialist engineering company with a global customer base. Greenbank provides a wide range of products and services to companies operating across a number of industries and is now establishing itself in the clean and wastewater sector. For many years the company has utilised the unique properties of volcanic basalt for lining products used in heavy industries such as power generation and minerals extraction. In partnership with Czech firm Eutit, the company has also been pioneering the use of basalt in the renovation and restoration of sewer systems in central European following a series of successful projects in Prague. As a result of devastating floods, the city’s sewer system was extensively rebuilt and upgraded with basalt being used in a number of key locations to provide a new level of security to the system. More than a decade on, the new system continues to perform well and has set a standard that’s now been followed in other European cities. Well suited for the most demanding of applications, thanks to the partnership between Greenbank and Eutit, a wide range of basalt solutions are now available in the UK market. These include products and systems that bring a wide range of benefits to the industry, including: Basalt tiles that can also be used to line existing brickwork, a more cost-effective solution than full replacement, and their reduced drag co-efficient means improved flow – in effect a smaller-diameter pipe or tunnel lined with basalt can carry a higher volume of water than a larger one with traditional brick surfaces. The effective life expectancy of basalt-lined sewer systems is between 100 and 200 years, thanks to their excellent resistance to abrasion and chemical damage – as well as the rigours of high-pressure water jetting that’s often used to clear unwanted blockages. For larger round or ovoid systems, basalt can be used in the lower sections to deal with the wear and tear with concrete upper sections to provide optimum life performance. Alternatively, steel pipes lined with basalt can be produced up to 3000mm diameter producing a lighter therefore lower cost installation option to thick wall concrete. Ease of installation and reduced maintenance costs make basalt ideal for bottom gutters, branch pipes and tubes and slip-resistant elements for walkways, and Greenbank can also supply bespoke-shaped tiles to meet the unique requirements of individual clients. With manufacturing facilities in Derbyshire and Nottinghamshire, supported by the additional capacity and expertise provided by the latest addition to the group, Franklyn Yates Engineering, Greenbank is well placed to react quickly and efficiently to the needs of new and existing clients.

    Water Engineering Services: Design, Procurement, and Delivery of Water Infrastructure

    Water engineering services encompass the full spectrum of professional and technical services required to plan, design, procure, construct, and commission water and wastewater infrastructure. Services cover feasibility, optioneering, detailed design (civil, mechanical, electrical, instrumentation, and control), CDM (Construction Design and Management Regulations 2015) principal designer duties, procurement support, construction supervision, and commissioning. Principal UK water engineering consultancies: Jacobs (formerly Halcrow and CH2M HILL), Mott MacDonald, Stantec (formerly MWH), WSP, Arcadis, Atkins (SNC-Lavalin), Binnies (Black and Veatch), AECOM, Arup, Hyder Consulting (now WSP), Grontmij (now Sweco), Brown and Caldwell, and Tetra Tech. Procurement frameworks: water company engineering services are typically procured through Alliance or collaborative delivery frameworks (Ofwat incentivises collaborative delivery under the CIRIA Alliancing best practice guide; Anglian Water's @one Alliance; United Utilities' Capital Delivery Alliance; Severn Trent Water's Capital Works Alliance); these multi-year frameworks (typically 5-year AMP periods) procure design, construction, and commissioning services through integrated teams. CDM: Principal Designer (PD) role under CDM 2015 must be appointed for all projects involving more than one contractor; PD coordinates health and safety during pre-construction design phase; Health and Safety File completed at project handover.

    Capital delivery and project management: major water infrastructure projects (treatment works, tunnels, reservoirs) are delivered under NEC4 (New Engineering Contract, 4th Edition) contract forms; NEC4 Target Cost (Option C) is dominant for complex projects where scope uncertainty exists; NEC4 Engineering and Construction Contract (Option A, Lump Sum) for well-defined civil engineering packages; Employer's Requirements (ER) or Performance Specification issued by water company; contractor designs to performance specification and employer's requirements rather than prescriptive design specification; early contractor involvement (ECI) is increasingly used (NEC4 Option W1 early contractor involvement or two-stage tender with ECI stage); RIBA Plan of Work for building elements (Stages 0 to 7); ICE (Institution of Civil Engineers) Design and Practice Guide for infrastructure projects. UK water industry investment: Ofwat Price Review (AMP periods); AMP7 (2020 to 2025): GBP 51 billion allowed investment across all water companies; AMP8 (2025 to 2030): final determinations issued December 2024; Ofwat's Innovation Fund (GBP 200 million); Water UK Capital Investment Survey published annually. Procurement OJEU thresholds (retained UK public procurement thresholds post-Brexit, Public Contracts Regulations 2015 as amended): works contracts greater than GBP 4,733,252; services contracts greater than GBP 378,660; water sector utilities procurers above threshold must advertise in Find a Tender Service (FTS, replacing OJEU for UK after Brexit).

    Frequently Asked Questions

    What contract forms are used for UK water infrastructure projects?

    The primary contract forms used for UK water infrastructure projects: (1) NEC4 (New Engineering Contract, 4th Edition, 2017): dominant form for water industry since Latham Report (1994) recommended NEC; main options: Option A (Priced Contract with Activity Schedule, lump sum per activity); Option B (Bill of Quantities); Option C (Target Cost with Activity Schedule - risk shared between contractor and employer via pain/gain mechanism; gain share up to agreed cap; most common for treatment works and complex projects); Option E (Cost Reimbursable, used for very high uncertainty projects); NEC4 includes: X clauses for specific requirements (X10 Information Modelling/BIM; X12 Partnering; X15 Limitation of Liability; X20 KPIs); early warning (EW) and compensation event (CE) mechanisms; project manager administers contract; W clauses for dispute resolution (W1 adjudication, W2 arbitration). (2) ICE Conditions (Institution of Civil Engineers): MF/1 (Model Form of General Conditions, used for mechanical and electrical plant contracts); FIDIC (Fédération Internationale Des Ingénieurs-Conseils): Red Book (EPC/turnkey projects, traditional); Yellow Book (plant and design-build); used for overseas projects and some UK private sector work. (3) JCT (Joint Contracts Tribunal): less common in water infrastructure; JCT DB (Design and Build) used for some building works (site offices, welfare facilities) within water projects. (4) Framework Agreements: water companies procure engineering services via multi-year framework agreements (typically 5-year aligned to AMP period); frameworks may be single-supplier or multi-lot; contractors compete through mini-competitions or call-offs within agreed rates.

    What is a hydraulic model and why is it used in water engineering?

    A hydraulic model is a computer simulation of a water distribution network or drainage system that predicts flows, pressures, velocities, and water quality through the pipe network under different operating and demand conditions. Types of hydraulic model: (1) Water distribution network (WDN) model (InfoWorks WS Pro, Bentley WaterGEMS, EPANET): simulates drinking water distribution from treatment works through trunk mains, service reservoirs, and distribution mains to customer connections; uses: leakage management (night flow analysis, pressure management zone design); fire flow analysis (minimum residual pressure 7 m at hydrant during fire demand, BS EN 1717); water quality modelling (chlorine decay, residence time, age); capital planning (main reinforcement, new reservoir sizing); burst prediction; pressure zone redesign. (2) Sewerage and drainage model (InfoWorks ICM, MIKE URBAN): simulates foul water flow through combined or separate sewer networks; uses: hydraulic capacity assessment (peak flow vs pipe capacity; surcharge depth); CSO performance modelling (spill volume, frequency); surface flooding prediction (2D surface overland flow model linked to 1D pipe model); SuDS impact assessment (upstream storage attenuation effect on downstream sewer); capital programme planning (sewer upsizing, storage tank sizing). (3) Groundwater model (MODFLOW, FEFLOW): groundwater flow and contaminant transport; used for groundwater abstraction licence assessment, dewatering design, contaminated land risk assessment. Model calibration: WDN models calibrated against flow meter and pressure logger measurements from field trials (step tests, fire hydrant tests); sewer models calibrated against continuous flow monitoring data from manholes.

    What qualifications do water engineers need in the UK?

    Water engineers in the UK typically hold degrees in civil engineering, environmental engineering, chemical engineering, or mechanical engineering, followed by professional chartership through the relevant institution. Academic routes: BEng or MEng in Civil Engineering (ICE accredited, e.g. University of Sheffield, Newcastle, Loughborough, Southampton); MEng or BEng in Environmental Engineering (CIWEM accredited, e.g. Imperial College, Cranfield); BSc in Environmental Science + MSc in Water and Wastewater Engineering (e.g. Cranfield MSc); alternatively BEng Chemical/Mechanical Engineering + water sector CPD.

CIWEM (Chartered Institution of Water and Environmental Management): MCIWEM (CEnv) for water and environmental engineers; directly relevant to drinking water, wastewater, and environmental compliance roles; assessed against 7 CIWEM competency areas. IChemE (Institution of Chemical Engineers): CEng MIChemE for chemical engineers in water treatment (desalination, membrane technology, process engineering); Chartered Engineer via AMIChemE then MIChemE routes. IMechE (Institution of Mechanical Engineers): MIMechE for mechanical engineers in water (pump and HVAC engineering, mechanical design). Typical career path: graduate engineer (3 to 5 years); senior engineer (5 to 10 years, typically CEng); principal/associate (10 to 15 years); technical director (15+ years). Salary ranges (2024, UK): graduate GBP 28,000 to 35,000; CEng 5 years GBP 45,000 to 60,000; associate director GBP 70,000 to 95,000; technical director GBP 90,000 to 130,000+.

    What is CDM and how does it apply to water infrastructure projects?

    CDM (Construction (Design and Management) Regulations 2015, SI 2015/51) is the primary UK health and safety regulation for construction projects. It applies to all construction work, including water infrastructure (treatment works, pumping stations, pipelines, reservoirs, service reservoirs). Key duty holders under CDM 2015: (1) Client: the organisation commissioning the construction work (water company, developer); must appoint a Principal Designer and Principal Contractor for projects with more than one contractor; notify HSE (F10 notification) for projects lasting more than 30 days with more than 20 simultaneous workers, or more than 500 person-days total; (2) Principal Designer (PD): appointed by client from design phase; must be a designer with control over pre-construction phase; coordinates H&S during design (identify and eliminate or reduce foreseeable construction phase risks through design decisions; ERIC principle: Eliminate, Reduce, Inform, Control); produces pre-construction information (PCI) and contributes to Health and Safety File at project completion; for water projects: CDM PD role held by lead design consultant (Jacobs, Mott MacDonald, WSP, Stantec, etc.); (3) Principal Contractor (PC): appointed by client for construction phase; produces Construction Phase Plan (CPP) before site works start; manages H&S during construction; (4) Designers: all organisations producing design (including specialist M&E designers, equipment suppliers producing installation drawings) must eliminate or reduce H&S risks through their design. Water-specific CDM risks: confined space entry (service reservoirs, pump stations, wet wells, tanks); working at height (chemical dosing platforms, process tanks, elevated pipework); hazardous chemicals (sodium hypochlorite, ferric sulphate, ammonia); asbestos in existing infrastructure; ground contamination on brownfield STW sites.

    Case Study·Water utilities capital delivery
    Challenge

    A water company in Yorkshire needed to deliver a GBP 32 million STW upgrade (new activated sludge lane, P removal, and biogas CHP) within AMP7 constraints. The project had already experienced a 7-month programme delay on an earlier design iteration due to late civil contractor engagement and a HAZOP finding that required a pressure vessel redesign.

    Approach

    The project was re-procured as an NEC4 Option C Target Cost contract with early contractor involvement (ECI) at RIBA Stage 2. Jacobs were retained as lead design consultant and CDM Principal Designer. The HAZOP was completed at detailed design stage (not post-procurement) with all duty holders present. A BIM Level 2 Common Data Environment (Asite) was established at project outset. The main civils contractor (Morgan Sindall Infrastructure) was appointed at RIBA Stage 2 to review constructability.

    Outcome

    The project was delivered 3 months ahead of the revised programme and GBP 1.4 million below the NEC4 target cost; the client's pain/gain share returned GBP 700,000 to the water company. The CDM Health and Safety File was completed and issued to the asset management team at handover. The BIM model was adopted by the water company's GIS team for ongoing asset management. No reportable HSE incidents occurred during construction.

    Questions to Ask Shortlisted Providers

    1. 1

      Which NEC4 contract option are you recommending and what is the rationale for the risk allocation between target cost and lump sum?

      NEC4 Option C (target cost) is appropriate for complex works with significant scope uncertainty; Option A (lump sum) transfers scope risk to the contractor at a premium; understanding the risk allocation logic helps you assess whether the contract form matches your project risk profile.

    2. 2

      At what RIBA stage will the main contractor be appointed and what early contractor involvement (ECI) activities are proposed before contract execution?

      Contractors appointed at RIBA Stage 2 can identify buildability issues before design is fixed; late appointment (RIBA Stage 4 or 5) means design changes that emerge during construction are compensation events at day-rate cost.

    3. 3

      How will the CDM Principal Designer role be managed and at what point will the HAZOP and SIL assessment be completed?

      HAZOP findings after procurement can require expensive equipment redesign; completing the HAZOP at RIBA Stage 3 before equipment selection and vendor enquiry ensures that any safety-driven changes are incorporated into the tender specification.

    4. 4

      What BIM Level 2 deliverables are required and how will the as-built model be handed over for integration with our GIS and asset management system?

      A BIM model locked in a proprietary format that cannot be imported into the water company's Maximo or ArcGIS environment is of little value; the Common Data Environment protocol and model handover format must be agreed before detailed design.

    5. 5

      How are the Ofwat AMP8 TOTEX efficiency incentives and ODI performance commitments built into the engineering services contract KPIs?

      Engineering consultants who are not remunerated against totex outcomes have no financial incentive to value-engineer or optimise; aligning consultant fee incentives with the water company's Ofwat regulatory performance commitments is the defining feature of modern alliance frameworks.

    What Drives Cost in This Category

    Programme certainty and procurement route

    An NEC4 Option C target cost with ECI typically costs 5 to 10 percent more in consultant and contractor overhead than a traditional lump-sum tender, but reduces the risk of compensation events that routinely add 15 to 30 percent to the final account on complex water infrastructure.

    Ground investigation and geotechnical uncertainty

    Ground investigation for a new STW tank foundation on a brownfield site costs GBP 50,000 to 150,000; inadequate investigation that leads to unforeseen ground conditions (soft clay, made ground, contamination) is the single most common cause of cost overrun on water infrastructure projects.

    Planning consent and Environmental Impact Assessment

    A major STW expansion triggering EIA (Town and Country Planning (EIA) Regulations 2017) adds 9 to 18 months to the programme and GBP 80,000 to 250,000 in consultant fees; Habitats Regulations Assessment (HRA) for sites near SACs or SSSIs adds a further 3 to 6 months.

    M&E equipment lead times and supply chain risk

    Post-2020 supply chain disruption extended lead times for submersible pumps (16 to 26 weeks), control panels (20 to 36 weeks), and membrane diffusers (12 to 20 weeks); projects that do not place long-lead equipment orders at RIBA Stage 3 risk programme delays that trigger NEC4 compensation events and Ofwat ODI penalties.

    Key Regulations & Standards

    CDM 2015 (SI 2015/51) Principal Designer Duty

    All water infrastructure projects involving more than one contractor must have a CDM Principal Designer appointed from design inception; the PD must produce pre-construction information (PCI), coordinate H&S in the design, and contribute to the Health and Safety File at project completion; HSE F10 notification is required for notifiable projects (30 days+ with 20+ simultaneous workers).

    NEC4 Contract Forms and Ofwat Regulatory Framework

    Ofwat encourages collaborative NEC4 delivery for AMP8 capital works; NEC4 Option C Target Cost with pain/gain sharing aligns contractor incentives with the water company's totex efficiency targets; early warning (EW) and compensation event (CE) mechanisms must be operated correctly to preserve the collaborative contract intent.

    Town and Country Planning (EIA) Regulations 2017

    New or significantly extended water treatment works (Category 10 infrastructure development, Schedule 2 EIA Regulations) may require Environmental Impact Assessment; a screening request to the local planning authority is required before design commences to determine whether an EIA is needed; failure to screen before commencing design can invalidate planning applications.

    FIDIC / NEC4 for RAPID Strategic Water Resource Projects

    Multi-company strategic water resource projects assessed through the RAPID (Regulators Alliance for Progressing Infrastructure Development) process may use FIDIC Yellow Book or NEC4 EPC-type contract forms for the delivery phase; Ofwat, EA, and NRW review RAPID submissions jointly and set programme milestones that feed into AMP8 Final Determination commitments.
