Our standard protocol for handling the estimating process captures hidden value for our clients

Darby Construction Services President, Paul Stanton is a Chartered Quantity Surveyor with over 10 years experience estimating commercial projects in New York City.

Based on this experience, we have developed a successful estimating process that has satisfied our clients:

  • When an RFP is received, documents are saved, printed and recorded in a document log. This log is updated any time new information is received.

  • The bid documents are then thoroughly reviewed and sub trades identified. Based on this review, a subcontractor list is then compiled. This subcontractor selection and each subcontractor is carefully qualified based on the project on hand.

  • Once the subcontractor list has been confirmed, a subcontractor RFP is created. This will include all relevant bid information, due date, insurance requirements and any break-out cost or alternate requests.

  • The next step is to conduct a site walkthrough to view existing conditions. Where possible (and relevant), subcontractors will also be invited to attend.

  • For larger projects, a full in-house take-off is done using computer software for accuracy.

  • Long lead items are identified and where applicable, recommended to client and design team for pre-purchase.

  • During the bidding phase, RFIs will be issued formally to the design team.

  • When all subcontractor bids have been returned, bids are fully leveled and qualified.

  • Once all bids are leveled, final numbers are determined and a proposal letter is submitted to the client showing a scope summary and a full trade cost breakdown.

After the proposal is submitted, Darby Construction Services will review the project with the client and answer any questions or concerns. Often, the client or design team will request some additional information or some value engineering solutions.
