Deliverables Rule of Thumb

DOCUMENTATION REQUIRED OVER PROJECT LIFE CYCLE

GUIDELINES FOR APPLYING DELIVERABLE STATISTICS TO THE PROVISION OF OUTSOURCED ENGINEERING DESIGN AND PROJECT MANAGEMENT DOCUMENTATION

Pro rata Design Costs Engineering design costs as a percentage of the total project installed cost (TIC) vary from project to project as they are dependent on, amongst other things, the type of plant and the size of the plant, the complexity of the design and the level of detail provided to the design office. Typically design costs as a % of the TIC fall into the following ranges. Design Element Feasibility Design Front End Design Detail Design CDM and Risk Management (CDM Project HS File & Plan) Planning Supervisor Construction management (CDM Notifiable site) including Principal Contractor

Percentage 1-2 5-10 15-25 12-20 5-10

Types of Engineering Documents (Deliverables) The types of deliverables normally produced on a typical multidisciplined capital project in the Chemical/Fine Chemical industry include :Type of Engineering documents (Drawings on ACAD R14 or LT) Layouts and Plot plans Piping and General Arrangements Process Flow diagrams Process P&IDs Process Hook ups - Break ins Piping Isometrics As builts

Engineering Manhours per drawing 40 60 20 30 4 2 1

Draughting Manhours per drawing 50 80 12 25 2.5 6 6

Checking Manhours per drawing 25 30 8 15 1 3 2

Other Engineering Documentation (Deliverables) Type of Document (Electronically generated) Technical Specifications Hazard and operability studies CDM Health & Safety File (Phase 1) CDM Health & Safety Plan (Pre Tender) Planning and scheduling Gantt Charts

Engineering Manhours per document 30 40 40 30 20

Non Technical Documentation Type of Document Placement of Purchase orders (Simple) Placement of orders (Complex)

Clerical Manhours/order 2.5 30

Checking Manhours per document 5 10 4 8 4

DOCUMENTATION REQUIRED OVER PROJECT LIFE CYCLE

Quantity of documentation The amount of documentation produced on a typical project has become quite considerable and should not be underestimated. The 1994 CDM regulations place a legally binding responsibility on the part of the Client to ensure that the designers, planning supervisors and principal contractors are all “competent”. Notifiable projects require a considerable amount of supporting documentation in order to satisfy the HSE. Failing to ensure that the designer, planning supervisor and principal contractors are appointed, and competence are two offences that can be committed under section 33 of the 1974 Health & Safety at Work Act. Failing to ensure that the Health & Safety File and Health & Safety Plan are prepared and available for inspection are also offences that can be committed by the Client.
