Construction services

Which construction services stay within our registration?

COSS CONSTRUCT (SRL) describes only its registered activities: road construction and reconstruction, site preparation, earthworks, base preparation, and organisation of construction processes. Singapore entry is planned only. This page matches your task to the right heading before you write to us.

Registered scope

Five headings, nothing beyond them

Read the kerb before the machines arrive. Every enquiry we accept sits under one of these registered headings. Pick the heading that carries most of your work, then describe the rest in plain words. We reply with planning questions, not site promises.

Road construction and reconstruction

Carriageway work and rebuilding of pavement structure — widening type tasks and milling and overlaying type tasks where the brief calls for them. Urban road jobs often combine several items at once: a new road extension, widening of an existing street, recambering, raising, milling and overlaying.

State the street section, current surface condition, and whether levels or width must change. We discuss sequence, tie-ins to drains and footpaths, and traffic-sensitive staging in planning terms. We do not promise execution timelines for Singapore, where approvals and appointed roles govern delivery.

Site preparation services

Making ground ready for what follows: clearing, levelling, access formation, and setting out work areas. In Singapore this pairs with utility protection and surface water control from the first day.

  • Hold cable and gas plans before any ground is broken.
  • Respect the 7-day notice of commencement to SP PowerGrid.
  • Follow the Letter of Requirements where cables and gas pipelines are present.

Tell us site boundaries, known services, and discharge points for surface water. That lets us respond with relevant planning questions.

Read Site Preparation Steps

Earthworks services

Excavation, movement, placement, and compaction of soil within the project limits, plus coordination with retaining structures where the package includes them. On network changes — interchange re-alignments and flyover widening tied to a new town — earthworks sit inside a wider programme, not alone.

Share depths, volumes if known, access constraints, and stockpile or disposal notes. Where an earthworks supervisor or erosion control plan applies in Singapore, those appointments and documents sit with the locally responsible parties.

Base preparation

The load-bearing work under the pavement: shaping, grading, and preparation of layers that set levels and falls. It connects directly to drainage — a base that ignores falls will hold water — and it sets the result for any overlay or reconstruction above it.

Note existing pavement build-up if known, drainage tie-in levels, and any soft spots or level faults.

Process ledger

How paving, base and reinstatement are ordered

Organisation of construction processes is the coordination layer: breaking work into stages, ordering operations, and aligning information between parties.

  1. Stage ARead the street section — surface, levels, drains and footpath tie-ins recorded before anything moves.Survey
  2. Stage BOpen ground with care — excavation and earthworks staged around utilities, access and stockpile.Dig
  3. Stage CShape the base — grading and falls set so water leaves the pavement, drainage levels tied in.Grade
  4. Stage DLay and reinstate — paving, milling and overlay, then kerbs, footpaths and markings made good.Pave
  5. Stage EHold the programme — several connected roads handled as one, with client interaction scheduled per stage.Steer

Corridor jobs such as the Changi Northern Corridor across Loyang Avenue, Telok Paku Road, Nicoll Drive and Changi Coast Road show why staging matters. Actual permits, traffic schemes, and site control remain with the authorities and appointed contractors in Singapore.

Planning register

Singapore entry is planned only

This plate states what we are not claiming, so your enquiry starts from facts. We keep replies to planning of sequence and information gaps — never to site promises.

  • No local office in Singapore is claimed. Our registered address is Chaussée de Gand 1426, 1082 Berchem-Sainte-Agathe, Belgium.
  • No ongoing projects, permits, or licences in Singapore are claimed or implied.
  • No completed projects, certificates, or technical capabilities beyond the registered wording are presented.
  • No building construction, structural design, utility operation, or maintenance contracts are covered here.

Working with us

Choose the right heading first

Routing guide

Many enquiries touch two headings. Name the main one in the project type field and describe the rest in the task box.

Stacked traffic drums with orange and white bands on concrete

Staging objects, flat light

Carriageway width or levels

Select road construction. Add the street section and whether the road must stay open, as on East Coast Parkway where traffic sensitivity shapes every stage.

Clearing and readiness

Select site preparation. Add boundaries, known services, and discharge points for surface water so the reply stays specific.

Digging, fill, formation

Select earthworks. Add depths, access constraints, and stockpile or disposal notes if you hold them.

Sequencing and coordination

Select organisation of construction processes. Describe how paving, base, excavation, drainage, and reinstatement should be ordered.

What we do not cover here

We do not present building construction, structural design, utility operation, or maintenance contracts. We do not list completed projects, certificates, or technical capabilities beyond the registered wording. We do not offer online payment or checkout. The only action is a consultation enquiry through the Contact page, with consent to personal data processing and regard to Singapore PDPA considerations explained in the Privacy Policy. This limit keeps the destination relevant to the ad or link you followed and avoids misrepresentation.
