CONSTRUCTING HEAVY INDUSTRIAL PROJECTS (CHIP)
CHIP has been published as a Kindle and paperback: "Industrial Construction - a handbook" and is available from Amazon Books. HTML codes for all the following EMMAs and Calculators are provided free in the book, enabling the user to embed same in his/her personal web-page or in any hosted web-page. Alternatively, book purchasers can make use of same in the following pages.
Reference numbers in brackets after subject headings eg (1) EARLY MANPOWER PLANNING (Ref. 4.1.) are cross-references to such subjects in the book.
ALSO PLEASE NOTE
Now published separately in book form is the section of CHIP which dealt with on-site manpower planning and offered advice on how to avoid major overruns of the schedule and cost of construction projects.
The book is fully illustrated with colour diagrams and examples to assist the reader.
(1) EARLY MANPOWER PLANNING (Ref 4.1.)
This 'CALCULATOR' 6.3. breaks down an estimated project cost into its main E P C components (WBS), for analysis & early manpower planning using typical weighted values. (Ball-park)
(2) TEMPORARY FACILITIES AREA (Ref 3.2.1.)
This check-list 6.4. serves to define & calculate the total area of ground required for temporary buildings, storage areas, roads, car parks etc
