Six disciplines.
One delivery team.

Archeve is a full-spectrum civil consultancy specialising in water, environmental and architectural engineering. Below — the six disciplines we lead, and what we hand over at the end of each stage.

01

Water engineering

Flood control, storm drainage, sustainable distribution and supply design — at the scale of a community, a stadium, or an entire new city quarter. End-to-end 2D direct-rainfall hydrodynamic modelling from preliminary hydraulics through IFC handover.

Water supply Distribution networks Fire-fighting systems HEC-RAS 6.5 InfoWorks ICM Stage 4 / IFC
  • 01Potable water distribution network — sizing, hydraulic modelling and node-pressure analysis to local code.
  • 02Fire-fighting and hydrant network design coordinated with civil defence standards.
  • 03Pumping station and reservoir sizing — TWL/BWL determination, hydraulic profiles.
  • 04Pressure-zone strategy and break-pressure tank coordination across changing terrain.
  • 052D direct-rainfall flood modelling (HEC-RAS 6.5 / InfoWorks ICM) for site-wide water strategy.
  • 06Detailed material schedules and IFC drawing sets ready for tender and construction.

Structural engineering

Structural analysis, geotechnical investigation, bridge hydraulics, and urban-planning support — from massing studies through scour assessment and detailed reinforcement design.

Structural analysis Bridge hydraulics Geotechnical HEC-18 scour BS / Eurocode / ACI
  • 01Concept-stage structural feasibility, framing options, and constructability review.
  • 02Geotechnical interpretation — bearing-capacity, settlement, and foundation typology selection.
  • 03Detailed analysis to BS / Eurocode / ACI, with finite-element modelling where useful.
  • 04Bridge scour assessment — HEC-18, CSU, HIRE, Froehlich, BREUSERS; total scour decomposition with bedrock cap.
  • 05Riprap protection sized to Isbash / HEC-23; reinforced grouted riprap in high-velocity zones.
  • 06Coordination with architecture, MEP and civil teams through clash-detection cycles.
03

Architectural design

Considered interior and exterior design across residential, civic and mixed-use typologies. Aesthetics led by use, climate and material — not by trend.

Concept Schematic design Design development Documentation
  • 01Programme briefing, site analysis and massing studies — climate, orientation, context.
  • 02Schematic design through design-development with material and façade studies.
  • 03Interior planning, finishes specification, and FF&E coordination.
  • 04Construction documentation set with full annotated detailing.
04

Stormwater management

End-to-end 2D direct-rainfall modelling with HEC-RAS 6.5, HEC-HMS, InfoWorks ICM, SewerGEMS and Autodesk InfoDrainage — underpinned by L-moments regional frequency analysis and an IPCC AR6 climate uplift on every design storm.

HEC-RAS 6.5 HEC-HMS InfoWorks ICM InfoDrainage SewerGEMS SuDS-compliant
  • 01Catchment delineation and sub-basin definition (Arc Hydro / WMS 11.2).
  • 02Rainfall frequency analysis — HEC-SSP, HYFRANPLUS, Python L-moments; GEV / LP3 / Gumbel cross-check.
  • 03Regional Frequency Analysis (Hosking & Wallis 1997) for ~50% variance reduction in data-scarce regions.
  • 04SCS-CN rainfall–runoff modelling (TR-55) with AMC I/II/III sensitivity in HEC-HMS.
  • 052D direct-rainfall hydraulic routing in HEC-RAS 6.5 and InfoWorks ICM — dual-software cross-validation.
  • 06SuDS strategy — bioswales, retention basins, percolation ponds, permeable surfaces — for water-quality treatment.
  • 07Climate-adjusted design storms (+30%, IPCC AR6) and resilience scenario testing.
  • 08CHIRPS satellite gap-filling for sparse gauge networks; spatial interpolation via IDW, Thiessen and Kriging.

Urban infrastructure

Civil infrastructure detailed design, coordinated multi-utility solutions, and Issue-for-Construction documentation — every deliverable signed off against the applicable national, municipal and international design code.

Detailed design Utility coordination IFC documentation MOMRAH ADQCC OHDS 2017
  • 01Road geometry, profile and cross-section design to local highway authority standards (OHDS / MOMRAH).
  • 02Wet and dry utility corridors with mandated clearances, crossings and headwall design.
  • 03Drainage profile development in Civil 3D — cut/fill balance, grading, drainage coordination.
  • 04Compliance against MOMRAH (KSA), Abu Dhabi DMT, ADQCC stormwater manual, OHDS 2017 and municipal codes.
  • 05Issue-for-Construction packages with full annotation, material schedules and BOQs.
06

MEP coordination

Wet-utility systems — water supply, wastewater, stormwater drainage and irrigation networks — modelled in Autodesk InfoDrainage and Bentley SewerGEMS, coordinated and signed off ready for site.

Water supply Wastewater Irrigation InfoDrainage SewerGEMS Revit / Civil 3D
  • 01Gravity and pressure sewer network design with hydraulic profile checks and HGL verification.
  • 02Building tie-in flows integrated from MEP into the wider stormwater network.
  • 03Attenuation tank sizing — controlled flooding at the 1:100-yr check event.
  • 04Irrigation network — landscape and pitch — with smart-controller integration.
  • 05BIM-led coordination with architecture, structures and dry utilities (Revit / Civil 3D).
  • 06Clash detection and resolution cycles to a defined LOD before IFC release.
