Project Estimating
This Practice defines the process of initiation and development of cost estimates for projects to ensure consistency and predictability of delivered projects. It provides key elements of the estimating process to enable the project team to deliver an estimate of a quality sufficient to match the agreed expectations between owner and project team. The process outlined covers initiation through establishment of final approved estimate, which becomes the project baseline budget. The cost estimate for a capital project is critically important to all stakeholders. Owners rely on cost estimates to validate the viability of a project’s return on investments through economic analysis. Engineering and construction companies utilize the cost estimate for developing their proposals and negotiating, which are key to securing work and ensuring their profitability. This Practice does not address the subject of cost control of the baselined project budget. The terms “project estimating” and “cost estimating” are used interchangeably.

Jacketed Piping Fabrication and Installation Details
This Practice describes the requirements for the design, material selection, fabrication, installation, inspection, and testing of jacketed piping systems. This practice is not a substitute for competent engineering analysis and design based on specific requirements of each project. Engineering should work with an experienced jacketed piping vendor to validate proposed system design and fabrication details.

Design and Fabrication of Bulk Solids Product Containers
This Practice provides requirements for the construction of cylindrical, atmospheric and low-pressure, welded, shop-fabricated or field-erected dry bulk solids bins, hoppers, silos, and gravity blenders. This Practice describes requirements for design, materials, fabrication, examination, testing, and shipping for cylindrical shell, single-wall containers for dry bulk solids having internal design pressures not exceeding 103 kPa (15 psig) and/or full vacuum external pressure at the top of the container in its normal operating position. Containers may be welded, shop-fabricated or field-erected, and shall generally be designed in accordance with the philosophy and requirements of the ASME Boiler and Pressure Vessel Code, Section VIII, Division 1, although inspections and marking are not required for these containers.

Guideline for Designing Industrial Cybersecurity
This Practice describes guidelines and background information for the selection, design, and operation of cybersecurity countermeasures in Industrial Control Systems (ICS). Also included is guidance for connection to enterprise systems, hardware selection criteria, software selection criteria, ancillary equipment requirements, and testing of ICS cybersecurity. General guidance related to cybersecurity for industrial control networks is addressed in this Practice in addition to covering allowable communication with external systems and securing communications between ICS and external networks. Building controls systems, enterprise systems, and other business-related operational technology systems are considered out of scope. This Practice also does not cover ICS cybersecurity risk assessment.
