> Contractor’s applications for payment
> Owner’s project payments
> Pay application back up documentation
> Contractor’s costs by major construction phase
> RFIs and scope changes

2. Reconcile project expenditures

Reconcile project expenditures obtain all project related financial or accounting transactions that document owner expenditures. It reconciles the sum of the total payments made to each vendor to the various contract amounts as adjusted by change orders. Also, it reviews a sample of invoices paid direct by the owner for services, materials or other costs which may have been the responsibility of the general contractor

job may have been working for subcontractors or affiliates without appropriate back charges. Also, it verifies allocation of payroll costs.

Labor burden analysis decomposes the labor burden and determines the basis for the contractor’s charges for payroll taxes, insurance, and fringe Audit for activity which may not be legitimate reimbursable costs.
It reviews other components of contractor’s labor burden charges for appropriate methodology in application Trace payroll charges to the contractor’s payroll register. Also, it decompose the union benefits charges and separate from labor burden charges

5. Change order analysis and pricing analysis

Change order analysis prepares a control schedule of owner change orders. It reviews the detailed change order backup documentation. It performs the recalculation of change orders.
