Contractor Billing & IPC Preparation

Technical billing and documentation support for contractors, subcontractors and construction companies in Pakistan - from measurement and running bills to Interim Payment Certificates (IPC), BOQ reconciliation and claims documentation.

Why contractors choose Struc-Arch

Your payments depend on your paperwork

Most payment delays and deductions are documentation problems, not site problems. Struc-Arch prepares the measurement, billing and supporting documents contractors need to get paid correctly and on time.

IPC Preparation

Interim Payment Certificates prepared from measurement sheets, with proper deductions for retention, mobilization recovery and prior payments.

Measurement & Running Bills

Work-done measurement, measurement sheets, running bills and final bills in line with the BOQ and contract documents.

Rate Analysis & BOQ Reconciliation

Rate analysis, extra-item rates, non-schedule item rates and BOQ reconciliation so every billed quantity is defensible.

Variation Orders & Extra Items

Variation order documentation, extra items, deviation statements and escalation calculations captured before they become disputes.

EOT & Delay Documentation

Extension of Time (EOT) documentation, delay records and supporting evidence so legitimate time claims are not lost.

Claims & Dispute Support

Technical documentation for contractor claims, quantity and payment disputes, and construction litigation support. Engineering and technical only - not legal representation.

What is an IPC (Interim Payment Certificate)?

An IPC is the certified statement of the value of work executed in a given period, prepared against the BOQ and contract, including additions, deductions, retention and prior payments. Contractors are paid against approved IPCs - accurate preparation matters.

Frequently Asked Questions

Common questions about contractor billing in Pakistan.

Who needs contractor billing and IPC services?

Contractors, subcontractors, builders and construction companies who need accurate running bills, Interim Payment Certificates, measurement sheets and claims documentation - especially where consultants or clients require professional documentation standards.

Where does Struc-Arch provide these services?

Struc-Arch is based in Gujranwala, Punjab, and supports clients across Pakistan - including Lahore, Islamabad, Rawalpindi, Sialkot, Gujrat and Faisalabad - plus international contractors.

What documents are needed for contractor billing?

Typically: the signed contract and BOQ, approved drawings, measurement sheets, site records, previous IPCs, rate analyses and any variation orders. Struc-Arch helps you organise these into a clean billing file.

What is the difference between a variation order and a claim?

A variation order is an instructed change to the works or rates agreed under the contract. A claim is a formal request for additional time or money arising from events under the contract - such as delays or changed conditions. Both need strong documentation.
