GUIDELINES FOR QUALITY ASSURANCE INSPECTION OF COMMERCIAL ACTIVITIES

CONTRACTS FOR REAL PROPERTY MAINTENANCE ACTIVITIES

GUIDE #8: GROUNDS MAINTENANCE

1 INTRODUCTION

Background

A Quality Assurance (QA) program allows the Army to evaluate and document a contractor's

performance. The Quality Assurance Evaluator (QAE) conducts skilled and carefully planned inspections

aimed at verifying the satisfactory completion of contractor work. The inspections evaluate the quality,

quantity, and timeliness of the services provided, not the contractor's methods used in performing the

work. A good QA program promotes the best possible product within the terms of the standing contract.

A well organized QA program depends on a QA Surveillance Plan (QASP), which is prepared by

the Government and contains the purpose and methods of the QA program. Although the QASP is not

a part of the contract, it is based on the contract Performance Work Statement, which is part of the

contract. The QASP lists contractor activities and the surveillance approach, approximate number of items

to be surveyed, and an Acceptable Quality Level (AQL) for each activity.

The installation Director of Public Works (DPW), the Contracting Officer (KO), or the Contracting

Officer's Representative (COR) often oversees the QASP. The COR/QAE needs an inspection guide to

help define and clarify the inspection tasks required by the QASP, and to facilitate inspection uniformity

and effectiveness. To meet this need, the U.S. Army Construction Engineering Research Laboratories

(USACERL) developed this series of 12 inspection guides.

Objective

This guide series is intended to supplement any existing QASP and to provide QA guidance for

evaluating Operations and Maintenance (O&M) work as performed by contractors on Army property. This

wastewater system guide contains recommended surveillance methods that can be amended by direction

of the KO or QA management to fit the needs of a specific installation.

Guide Series Organization

This series includes the following guides by USACERL published in October 1993:

#1: Water Systems (Special Report [SR] FF-94/01)

#2: Wastewater Systems (SR FF-94/02)

#3: Natural Gas Distribution Systems (SR FF-94/03)

#4: Electrical Systems (SR FF-94/04)

#5: Heating Systems (SR FF-94/05)

#6: Ventilation, Air Conditioning, and Refrigeration Systems (SR FF-94/06)

#7: Building Services (SR FF-94/07)

#8: Grounds Maintenance

#9: Surfaced Areas (SR FF-94/09)

5
#10: Refuse and Recyclable Handling (SR FF-94/10)

#11: Pest Control Services (SR FF-94/1 1)

#12: Custodial Services (SR FF-94/12).

The QAE is expected to evaluate a contractor's performance by applying appropriate visual and

instrumentation procedures along with necessary technical and interpretive skills. This guide covers QAE

inspection of grounds maintenance, and is divided into sections that take the inspector through a step-bystep process of recommended performance indicators, inspection tasks, and surveillance methods.

Grounds maintenance is divided into four subsystems in this guide:

1. Special Grounds Maintenance

2. Improved Grounds Maintenance

3. Semi-Improved Grounds Maintenance

4. Unimproved Grounds Maintenance.

General QA information, including detailed explanations of the available surveillance methods, is

given in Chapter 2.

Chapter 3 provides performance indicators, inspection tasks, and recommended surveillance

approaches for each subsystem.

Appendix A contains sampling inspection tables. Appendix B contains QAE Worksheets for each

subsystem; they may be reproduced for field use.

2 GENERAL QA INSPECTION INFORMATION

Inspection Organization and Planning

According to custom and standard practice, the contractor submits copies of the previous month's

O&M activities and regulatory agency reports to the COR and the QAE. The due dates of these reports

control the start of inspection scheduling. If possible, the QAE's inspection should be conducted within

3 days after receiving the reports. Effective coordination will allow more efficient inspection of services.

The COR/QAE should look for specific indicators of the contractor's performance and should evaluate

that performance based on Detail Inspection Tasks. The following chapter lists the Performance Indicators

and Detailed Inspection Tasks for grounds maintenance.

Quality Assurance Surveillance Methods

The QAE can use the following five surveillance methods to determine contractor performance:

1. Random Sampling

2. Planned Sampling

3. 100 Percent Inspection

4. Unscheduled Inspection

5. Customer Complaints.

Random Sampling

The methods are based on statistical criteria provided in Military Standard (MIL-STD)-105E,

Sampling Procedures and Tables for Inspection by Attributes (10 May 1989) and are presented as

recommendations. The methods used should be based on the unique needs of an individual system.

Generally, all five methods are not used to evaluate an individual system.

Random sampling is recommended for situations where many work items are candidates for

inspection. For instance, because it is impractical to inspect every roof on an installation with

500 buildings, only a select number of the buildings should be inspected. Likewise, in random sampling,

only a portion of the total performed work is inspected. Acceptance of the work is based on the

assumption that the inspected items are representative of the quality of the contractor's work. The random

sampling technique spreads the selected samples evenly throughout the evaluation period. The following

are steps to be used by the QAE in random sampling.

Tables Al and A2 in Appendix A should be used to determine the number of samples to be

inspected and the number of rejects allowed as a function of the number of inspected work items for

AQLs of 4 and 10 percent, and the level of surveillance. The three levels of surveillance are: normal,

increased (tightened), and reduced. Initially, this guide recommends normal surveillance for random

sampling. However, under the direction of the KO, the level of surveillance can be changed depending

on the contractor's performance.

As an example, assume that the contractor's total scheduled output (i.e., population size) for a

particular work item is 125 units and that the normal surveillance level with an AQL of 4 percent has been

selected. According to Table Al, 20 of the 125 units of work should be inspected, and the entire output

of 125 units should be rejected if 3 or more of the 20 sample units are not acceptable.

7
The QA Worksheets in Appendix B provide room to record the population size, the number of

samples, the maximum number of rejects, and the interval for each Performance Indicator.

The work planned by the contractor for each maintenance task should be listed by date to make it

easier to predict the time when the work samples will be ready for inspection.

Planned Sampling

Evaluation by planned sampling inspects some, but not all, of the work activities and is appropriate

when the number of work items is large. Some items are evaluated before scheduled completion because

they are inaccessible after the work is completed. The COR/QAE subjectively selects key work items for

inspection; the sample size is determined arbitrarily.

The COR/QAE will normally use planned sampling when the contractor's performance at selected

locations or tasks is poor. With this type of evaluation, the contractor knows that work performed in these

areas is more likely to be monitored. Planned sampling provides a systematic way of focusing on specific

output and forming conclusions about the contractor's performance level.

100 Percent Inspection

Inspection at 100 percent requires total inspection of all items in a contract requirement. It is

normally used to monitor infrequent work or critical contract work when the number of work items is

small and in cases where nonperformance could seriously damage Army-furnished equipment or processes.

It may also be used in areas where a contractor has had prior performance difficulties.

Unscheduled Inspection

Unscheduled inspections can be used for areas of poor past contractor performance, noncritical areas,

areas of infrequent repairs, or as a follow-up check of previous inspections. If the QAE notices such an

area, an unscheduled inspection can be conducted to evaluate contractor performance.

Customer Complaints

The customer complaint method is based on an informed and cooperative customer population, that

is generally aware of local contract requirements. Customers are expected to monitor contractor services

and, when performance is poor or nonexistent, to notify the COR/QAE. If investigation reveals that the

complaint is valid, the COR/QAE documents the deficiency. Since this is a reactive QA inspection

approach, this method of surveillance normally supplements planned inspection methods.

Increased Surveillance

For areas of poor past contractor performance, the QAE should consult with the KO to intensify the

surveillance method. More than one option is usually available, and selection should be based on the

initial method and the amount of work performed.

i. Random Sampling (Normal Surveillance) can be replaced by:

"* Random Sampling (Increased Surveillance)

"* Planned Sampling (for a large population size)

8
* 100 Percent Inspection (for a small population size)

* Unscheduled Inspection (for any population size).

2. Planned Sampling can be replaced by:

0 Random Sampling (Normal Surveillance)

0 100 Percent Inspection (for a small population size)

0 Unscheduled Inspection (for any population size).

3. Unscheduled Inspections can be replaced by:

* 100 Percent Inspection (for a small population size)

* Random Sampling (Normal Surveillance)

* Planned Sampling.

Decreased Surveillance

For work areas in which the contractor maintains a consistently satisfactory performance for 3 to

6 months, the QAE should consult with the KO to decrease the intensity of the surveillance. More than

one option is usually available and selection should be based on the initial method and the amount of work

performed.

1. Random Sampling (Normal Surveillance) can be replaced by:

"* Random Sampling (Reduced Surveillance)

"* Planned Sampling

"* Unscheduled Inspection (for any population size)

"* Customer Complaints.

2. Planned Sampling can be replaced by:

"• Unscheduled Inspection (for any population size)

"* Customer Complaints.

3. 100 Percent Inspection can be replaced by:

* Random Sampling (Normal Surveillance)

* Random Sampling (Reduced Surveillance)

* Planned Sampling

* Unscheduled Inspection (for any population size)

• Customer Complaints.
