The Need for Cost Analysis in Landscape Maintenance

An accurate analysis of the costs of specific tasks done by a landscape maintenance firm has several values:

* It assures that all costs to the firm are recognized.

* It permits a fair price to be charged to the customer.

* It allows a comparison of the profitability of different tasks.

* It can compare the efficiency of different crews performing the same task.

The first two benefits were discussed in Chapter 14. They are equally important in landscape maintenance. The last two warrant explanation also. A new landscape maintenance firm often believes that all jobs are good jobs. "No job is too big or too small" is the way their advertisements often read. Actually, as a firm grows, not all jobs can be accepted. There may be insufficient time or personnel to respond to every client request. The tasks that return the greatest profit for the labor invested will need to be emphasized over those that return less profit. A carefully prepared cost analysis can illustrate these different profit potentials.

The performance efficiency of several crews or laborers doing the same task can also be compared with a maintenance cost analysis. Assuming the cost of materials and the site conditions to be the same, the labor time required is the only comparable variable. Carefully kept work records documenting the crew size and hours of labor required to complete a task permit the performance comparison.

Features of the Maintenance Cost Analysis

A cost analysis of a landscape maintenance job includes

* a listing of all tasks to be performed

* the total square footage area involved for each service

* the number of times each service is performed during the year

* the time required to complete each task once

* the time required to complete each task annually

* the cost of all materials required for each task

* the cost of all labor required for each task

Unit Pricing

The most precise method of tracking job costs and determining the correct price to charge a client is unit pricing. It is also the method that requires the most time to set up because of the amount and precision of the data that is required. It is not a system that permits guess-timating. The system reduces all area dimensions and material quantities to common and measurable units, such as a thousand square feet or an acre. It measures the quantities and costs of materials used for particular projects in terms of those same units (for example, the application of one pound of nitrogen per thousand square feet of lawn area at a cost of $3.00 per thousand square feet). The initial conversion of material costs purchased in bulk quantities to unit costs that permit their use in the company's pricing system may take some time, but it is not difficult math and can be done.

Determining the time requirements for separate tasks and getting them to match the units used for calculating material costs is more difficult. The time required to perform a task is directly affected by the number of people on the crew, the type, size, and speed of the equipment being used, site conditions such as terrain, obstacles, and weather, and even the efficiency and/or work ethic of the workers. There are numerous time charts published by industry trade groups and the media that offer average unit times required to do typical landscape tasks, such as lawn mowing, shrub installation, mulching, or pruning. They are at best guidelines and should not be used as anything more than that. As a landscape company prepares to set up its unit pricing system, it must do some careful calculating of the time its crew people require to perform specific tasks using specific equipment and operating under specific conditions. These calculations can then be converted to the required time units, such as minutes per thousand square feet. It is important to realize that when one of the variables changes, e.g., the terrain goes from flat to rough or a larger mower is used, the time required per unit will change as well.

Calculations for Cost Analysis

To apply the technique properly requires practice. Study the following examples and their explanations.

Example 1

Problem:

To calculate the cost of mowing 10,000 square feet of lawn with an 18-inch power mower 30 times each year.

Necessary Information:

It takes 5 minutes to mow 1,000 square feet. The laborer receives $6.50 per hour. There are no material costs.

Solution:

Maintenance Operation: Lawn mowing with 18-inch power mower

Square footage area involved 10,000 sq. ft. Number of times performed annually 30 Minutes per 1,000 sq. ft. 5 Total annual time in minutes (1) 1,500 Material cost per 1,000 sq. ft. none Total material cost none Wage rate per hour $6.50 Total labor cost (2) $162.50 Total cost of maintenance operation per year $162.50 Square footage area involved 2,000 sq. ft. Number of times performed annually 1 Minutes per 1,000 sq. ft. 30 Total annual time in minutes (1) 60 Material cost per 1,000 sq. ft. $165.00 Total material cost (2) $330.00 Wage rate per hour $6.50 Total labor cost (3) $6.50 Total cost of maintenance operation per year (4) $336.50

Example 2

Problem:

To calculate the cost of mulching 2,000 square feet of planting beds with wood chips, 4 inches deep.

Necessary Information:

The task is done once each year. It requires 30 minutes to mulch 1,000 square feet, 4 inches deep. The laborer receives $6.50 per hour. The wood chips cost $165.00 per 1,000 square feet of coverage.

Solution:

Maintenance Operation: Mulching plantings with wood chips, 4 inches deep

Note:

(1) To obtain the total annual time in minutes:

a. divide the square footage of area involved by 1,000 [10,000 sq. ft. / 1,000 = 10]

b. multiply by minutes per 1,000 sq. ft. [10 x 5 = 50 minutes]

c. multiply by number of times performed annually [50 minutes x 30 = 1,500 minutes]

d. enter answer under total annual time in minutes

(2) To obtain the total labor cost:

a. divide the total annual time in minutes by 60 minutes [1,500 minutes / 60 minutes = 25 hours]

b. multiply by the wage rate per hour [25 hours x $6.50 = $162.50]

c. enter answer under total labor cost

Note:

(1) To obtain the total annual time in minutes:

a. divide the square footage of area involved by 1,000 [2,000 sq. ft. x 1,000 = 2]

b. multiply by minutes per 1,000 sq. ft. [2 x 30 = 60 minutes]

c. multiply by number of times performed annually [60 minutes x 1 = 60 minutes]

d. enter answer under total annual time in minutes

(2) To obtain the total material cost: a. divide the square footage of area involved by 1,000 [2,000 sq. ft. / 1,000 = 2]

b. multiply by material cost per 1,000 sq. ft. [2 x $165.00 = $330.00]

c. multiply by number of times performed annually [$330.00 / 1 = $330.00]

d. enter answer under total material cost

(3) To obtain the total labor cost:

a. divide the total annual time in minutes by 60 minutes [60 minutes / 60 minutes = 1 hour]

b. multiply by the wage rate per hour [1 hour x $6.50 = $6.50]

c. enter answer under total labor cost

(4) To obtain the total cost of maintenance operation per year:

a. add total material cost and total labor cost [$330.00 + $6.50 = $336.50]

b. enter answer under total cost of maintenance operation per year

The Completed Cost Estimate

A full cost estimate for maintenance is simply an enlargement of the previous examples. For convenience, all of the maintenance operations that deal with the same area of the landscape are grouped together in the estimate. Study the following example and note the calculation of all figures.

Data

I. A landscape requires the following maintenance tasks and equipment:

a. 24,500 square feet of lawn cut 30 times each year with a power riding mower

b. 500 square feet of lawn cut 30 times each year with an 18-inch power hand mower

c. all lawn areas fertilized twice each year

d. 5,000 square feet of shrub plantings fertilized once each year

e. shrubs pruned once each year

f. 400 square feet of flower beds requiring soil conditioning once each spring

g. flowers planted once each year

h. flowers hand weeded 10 times each year

i. flower beds cleaned and prepared for winter once each autumn

II. Calculated time requirements for the maintenance tasks:

a. a power riding mower cutting 1,000 square feet of lawn in 1 minute

b. an 18-inch power mower cutting 1,000 square feet of lawn in 5 minutes

c. lawn fertilization requiring 3 minutes per 1,000 square feet for spreading

d. shrub fertilization requiring 5 minutes per 1,000 square feet

e. pruning time for shrubs averaging 60 minutes per 1,000 square feet

f. soil conditioning for flower beds requiring approximately 200 minutes per 1,000 square feet

g. flower planting requiring 600 minutes per 1,000 square feet

h. weeding of flowers requiring 60 minutes per 1,000 square feet

i. cleanup of flower beds in the autumn requiring 400 minutes per 1,000 square feet

III. All laborers receive wages of $6.50 per hour.

IV. Material costs:

a. lawn fertilizer at $5.00 per 1,000 square feet

b. shrub fertilizer at $6.00 per 1,000 square feet

c. conditioning materials for flower beds at $3.00 per 1,000 square feet

d. flowers for planting averaging $125.00 per 1,000 square feet

V. Overhead and profit. To convert the cost analysis to a cost estimate, additional charges for overhead and profit must be added. As described in Chapter 14, these charges may be figured as a percentage of the total cost of the maintenance operation. In this example, overhead costs of 10 percent ($54.85) and profit allowance of 25 percent ($137.11) could be added to the $548.45 cost to the firm. The price quotation to the client would then be $740.41.

NOTE: Many firms apply different overhead and profit percentages to different parts of a project, rather than using single percentages, as in this example.
