CPV Code 4523, Road Construction

What does CPV code 4523 cover?

CPV code 4523 (Road construction) covers the construction, renewal and maintenance of roads, paths and traffic surfaces. This includes asphalt road construction (base courses, binder courses, surface courses), paving works (concrete block paving, natural stone, clinker), kerb and gutter works, cycle and footpath construction, and surfacing of car parks, bus stations and other traffic areas.

Road construction is one of the highest-volume segments in public construction. German municipalities alone invest billions annually in maintaining and expanding their road networks, supplemented by federal and state roads.

Who uses this CPV code?

Road construction tenders come from all levels of public administration: municipalities (local roads, residential streets, car parks), county and state authorities (county and state roads), and the federal Autobahn GmbH (motorways and federal roads).

Bidders include road construction companies, asphalt mixing plants with installation capacity, paving companies and large construction groups with road-building divisions.

How does Patterno help?

Patterno HIT enables road construction companies to search specifically for tenders within the right radius of their location or mixing plants. The AI distinguishes between new construction, resurfacing and maintenance measures.

Patterno BID supports calculation of road construction bills of quantities. For resurfacing programmes with many similar items, automated calculation can massively accelerate bid preparation.

Sustainability trends

Public road construction faces a sustainability shift: recycled asphalt, low-temperature asphalts and noise-optimised surface courses are gaining importance in tenders. These trends create new market opportunities for specialised companies.

Simultaneous repair works in the Villa located in the area and other repair and maintenance works commissioned by the client in the conference and course center may occur; the contractor must coordinate their work accordingly. Work areas inside the building must be clearly demarcated, unauthorized access to work areas and rooms with disconnected water/sewer must be prevented, and dust control must be ensured. For site traffic and transport planning, a weight-restricted bridge on the access road must be considered.
