Consultancy & Design

Civil Engineering

Core civil design and detailing for roads, drainage, water supply, retaining structures and site development — dimensioned so the site team can build from it without a phone call.

Overview

Why this matters on your contract

A civil design is only finished when someone can build from it. Drawings that are technically correct but dimensionally incomplete generate a stream of site queries, each one a small delay and an opening for a variation claim. We treat the site engineer as the real audience for every sheet we issue.

Our civil team works across roads, drainage, water supply, earthworks and general site development, to Nepal Road Standards, departmental specifications and the relevant district rate framework. Where a design decision has a cost consequence — a steeper gradient against a longer retaining wall, a deeper invert against a pumping station — we set the options out with quantities attached so the choice is made on numbers.

Scope

What the service includes

Every element below is covered as standard. Anything outside it is quoted separately and agreed before we begin.

Alignment, profile and cross-sections

Horizontal and vertical geometry to the applicable road standard, with full cross-section sets at the required chainage interval.

Drainage and hydraulic design

Catchment analysis, culvert and drain sizing, outfall design and roadside drainage detailing sized for realistic return periods.

Earthwork and mass-haul optimisation

Cut and fill balance, haul distance analysis and borrow or spoil strategy — usually the single largest cost lever on a road package.

Retaining and protection structures

Gravity, cantilever and gabion retaining walls, slope protection and river training works appropriate to hill and terai conditions.

Water supply and distribution

Pipeline sizing, reservoir capacity, pressure zoning, house connection layouts and thrust block detailing.

Site development and layout

Grading plans, access and internal roads, parking, external services routing and boundary treatment.

Our Approach

How we do this differently

01

Dimensioned for the field

Every drawing is checked for the setting-out information a site engineer actually needs. Missing dimensions are treated as errors, not omissions.

02

Quantities come with the design

Because we also quantify for a living, our drawings are produced in a way that makes measurement straightforward and unambiguous.

03

Terrain reality, not template design

Hill alignment and terai alignment are not the same problem. Our detailing reflects where the project actually is.

Questions

Common questions

Yes. Road geometry, pavement composition, drainage and structures are designed to Nepal Road Standards and the relevant DoR specifications, and we routinely prepare packages that are reviewed and approved by departmental engineers.

Yes, and we begin by auditing what exists so you know precisely what is usable. We will tell you if starting again is faster and cheaper than repairing an incomplete set — sometimes it is.

Always, unless you ask us not to. Take-off sheets are handed over with the drawing set so the quantity can be traced to the exact sheet and dimension it came from.

Free scope review · No obligation

Send us the document. We will tell you exactly what it needs.

A bidding document, a contract, a stalled bill, a stack of unrecorded measurements — whatever the position, a senior engineer will review it and come back within one working day with a written assessment, a timeline and a fixed price. There is no charge for this and nothing to sign.

NDA signed before any document is shared Response within one working day Fixed written fee, no hourly billing
