INTRODUCTION
Tremco
Incorporated Andrews Air Force Base Section 1, Introduction
REPORT CONTENT
Your report provides information essential to the analysis of your roofing investment and development of action plans. It will assist you to effectively and efficiently manage your roofing expenditures. The data you need in order to maintain your roofs in the optimum condition and preserve your substantial investment is provided.
Information is organized into the Executive Summary section followed by details for each roof. The Executive Summary provides overall information on your roofing inventory, asset value, the condition of roofs and budget amounts for maintenance, replacement and restoration work. Information is presented in numerical and graphical formats and is supported by data and recommendations for each individual roof area.
A roof area is defined by the following feature(s): An elevation change separation by walls, fire walls, expansion, control joints or a change of construction.
INFORMATION COLLECTION
Information collected includes historical data, construction and condition information. The information is collected by well trained, experienced roof inspectors. The inspection consists of on-site interviews whenever possible, a visual examination of the roof and extractions of roof samples for analysis. All accessible roof projections and equipment are inspected.
Information about the roof insulation and deck are based on what the inspector is able to determine by field examination of a core where possible and a visual examination of the underside of the deck if accessible.
This report and associated recommendations are based on the conditions at the time of the inspection. Both conditions and recommendations will change with time, weather and normal wear and tear associated with roofs.
CONDITION CATEGORIES
Your inspected roofing inventory has been classified into condition categories. Based on this analysis of certain key characteristics and noted conditions on each roof. Some conditions are clear indicators of future problems. Prompt attention to certain issues now may avoid or forestall a major expenditure later.
The condition categories are as follows: 1 . 0 - Red 2 . 10 - Red 3 . 20 - Red 4 . 30 - Amber 5 . 40 - Amber 6 . 50 - Amber 7 . 60 - Amber 8 . 70 - Amber 9 . 80 - Green
10. 90 - Green
11. 100 - Green
12. No Condition Recorded
The assignment of a roof to one of these categories is based on data collected. It does not take into account owner preferences or knowledge of a building or its anticipated future. These factors must be the subject of discussion using the inspection data as a base. This step may well result in a re-organization priority assessment.
FOLLOW-UP WORK
Expanded recommendations, comprehensive specifications and pertinent cost estimates will be provided to you upon request, based on a more exhaustive on-site examination of the roof areas identified as priorities.
Use the services of Tremco Incorporated Account Executive to supplement the information in this report to help in establishing priorities and in the management of your roofing investment.
