Brownfield Construction Package

Brownfield construction packages refer to projects that involve the development or expansion of facilities, infrastructure, or properties that are already in use or have existing structures. These projects are typically more complex than greenfield projects, which involve building on undeveloped or unused land. Brownfield construction packages come with their own set of challenges and considerations.

Tie-in List

A tie-in list typically refers to a list of components, materials, and equipment needed to connect or tie into an existing piping system. Here you define if it is a field weld or a connection to an existing valve.

You have to specify in what phase it will be or will it be in shutdown.

Demolition Photo book

 In this document, you define the specific piping, equipment, or items that require demolition, with tie-in numbers indicated. Some companies I’ve worked with prefer to have a demolition isometric drawing, but such a request should be agreed upon at the beginning of the project.

Isometric

Aside from the normal isometric drawing, you can add scope breaks between existing and new to clearly indicate the start of the new or end of the existing piping.

Scope of Work

These documents should encompass the commercial aspects, the schedule of actions for the contractor, accommodation arrangements, identification of the responsible party for delivery, technical specifications, scope, and all other actions required during the construction process. 

Typically, the Lead Piping Engineer prepares this document including the package for RFQ (Released for Quotation) to contractors. Contractors then provide quotations, which are reviewed both commercially and technically. The commercial aspect is evaluated by the Procurement team, while the technical aspect is assessed by the Lead Piping Engineer through a technical bid evaluation. The bid evaluation and a questionnaire to clarify any outstanding items are sent to the contractor. If all questions are answered and the offer is clear, the selection process proceeds, and eventually, the contract is awarded.

MTO – Material Take-off

The material Take-off should be as complete as possible. The Material Take-off document should include the quantity, size, description, material, and pipe specification

When an RFQ (Request for Quotation) is sent, the 90% model review should have already been completed. Of course, this can vary on a case-by-case basis. For the RFQ with the contractor, you can ask for the unit price per item in preparation in case additional scope is added, ensuring transparent pricing.
