Site Selection & Area Allocation
Maximizing Existing Facilities Consider the Following Areas for Cube Utilization: Under the floor. Basements are the biggest user of under floor space. Evaluate using for walkways (between buildings) and utility runs. Overhead. Various usages. Roof. The roof could be used for recreational endeavors, central A/C units, silo for material storage, water towers, etc. Get it off the floor.
Maximizing Existing Facilities Truss level. A truss is a rafter. Depending on the truss layout; offices, walkways, heaters, utilities, etc. can be located off the floor. Clear Space. Clear space is that space from 8 feet above the floor to the ceiling. Install mezzanines, racks, overhead conveyors, etc. in this area.
The Shell Game WAS NOW OPEN OPEN It is easier to move equipment into an open area rather that try and rearrange in place and meet production schedules.
Site Types Brown Field – A previously developed parcel Typically have incentives (tax, development, economic growth, etc.) attached to them Existing facility usually present Watch for contamination (chemical, oils, etc.) Green Field – Untouched parcel of property Allows for “new” layout Can have incentives attached for their development

Determining Building Size Determine the total space requirements Utilize a worksheet (Excel) Include all aspects of the operation Include outside areas (parking, shipping & receiving maneuvering area) on the worksheet Round up to the nearest “standard size” 100 x 100, 50 x 50, 40 x 40, and even 25 x 50 feet Size refers to column spacing inside the facility A 2-to-1 length to width ratio is desirable (rectangle)
Total Space Requirement Worksheet
Building Size Determination Our example building needs to be 18,735 sq. ft. No one would build this size building due to cost. We need to establish the 2-to-1 ratio first. Step 1- Divide by 2 18,735 / 2 = 9367.5 sq. ft. Step 2- Square root 9367.5 sq. ft. = 97 ft. Step 3- Round to a multiple of 25 & 50 ft. 97 ft. = 100 ft therefore (2-to-1) = 100 ft. x 200 ft.
Building Size Determination At 100 x 200 ft., this is essentially two 100 x 100 ft. areas. Total area is 20,000 sq. ft. A comparable square building would need to be 137 x 137 ft., rounded to 150 x 150 or 22,500 sq. ft. The 2-to-1 rule yields a space savings of 2,500 sq. ft. Additionally, a square building tends to put an employee farther from an emergency exit.
Dimensionless Block Diagram With the starting size of the building known, begin by developing the dimensionless block diagram. Maintain the relationships between the block diagrams and the final layout.
Area Allocation Procedure Establish the 100 x 200 ft. grid using graph paper. Start with the walls and columns only. 100 ft. I I I I 200 ft.
Area Allocation Procedure 2. Calculate the number of “squares” (400 square feet) needed by each department. Department Sq. Ft. Blocks Fabrication Spot weld Paint Assembly 2,238 1,170 4,200 912 6 3 11
Area Allocation Procedure 3. Place the blocks into the area allocation layout using the dimensionless block diagram as a guide. R S F Util W SW F TR W SW F TR W Ship F PO W P Assy C RR LR O 1,300 sq. ft.
Area Allocation Procedure Layout the internal walls or area boundaries. Present the layout and receive a final approval. Begin the detailed layout. Show all equipment and utility requirements.
Office Area Allocation Procedure is similar to the manufacturing layout Use the organizational chart as a guide Use 200 sq. ft. of space per person as a guide i.e. 36 employees x 200 sq. ft. = 7,200 sq. ft. 7,200 sq. ft. / 2 = 3,600 sq. ft. 3,600 sq. ft. = 60 ft. 2-to-1 ratio = 60 ft. x 120 ft.
