Highways, Bridges & Transportation

Highway, Bridge & Transportation Engineering in Pakistan

Pakistan’s road and highway network is the backbone of the nation’s economy, connecting cities, facilitating trade, and enabling growth. Arch-Tech Engineering Consultant Pvt Ltd has been a trusted partner in developing that network for over a decade, bringing internationally-trained highway engineers and planners to some of Pakistan’s most demanding road infrastructure projects.

Our transportation engineering division has designed and supervised approximately 320 kilometres of highways and motorways across Pakistan, Afghanistan, the United Kingdom, and China — a track record that few consulting firms in the country can match. From rural farm-to-market roads to urban interchanges, from mountain tunnels to metropolitan flyovers, Arch-Tech’s highway engineers have the experience and technical depth to deliver.

FAQ’s

Arch-Tech uses AASHTO, Pakistan Highway Code, British Standards (where applicable), and BREEAM standards for pavement and highway design. For international projects, we adapt to the relevant national standards of the project country.

Yes. We conduct traffic surveys, traffic counting, turning movement counts, and prepare Traffic Impact Assessments (TIA) for new developments, interchanges, and infrastructure projects across Pakistan.

Yes. Our structural and highway teams collaborate to deliver complete bridge engineering services — from feasibility and detailed design through to construction supervision and completion. We design reinforced concrete, pre-stressed concrete, and steel bridges.

Yes. Arch-Tech has experience evaluating BOT (Build-Operate-Transfer) and BOO (Build-Own-Operate) projects, including financial and technical due diligence, traffic revenue forecasting, and independent engineer roles on privately financed highway projects.

The Crystal Interchange is a grade-separated interchange project in the United Kingdom on which Arch-Tech’s engineers provided consultancy services. It is a key reference project demonstrating our capability to deliver road infrastructure consultancy to UK Highways Agency standards.
