## Example 1 (J0713): cover
Forms: Defective Manhole. Location: SW manhole 3, service road. Opening 550 x 550 mm. Grade D400. Heavier grade required: No. Surface: Tarmac. Part required: New manhole framework. Tarmac resurfacing.
Steps: 1.1 cover. 2.2 "Part required" orders a new framework -> replace. 3.1 one cover. 4.5 square 550 mm -> CVR-600-?; 4.13 square, D400 -> H: CVR-600-H x1. 5.1 one normal cover -> LAB-CIV-H 1. 6.1 SRV-UTIL 1, WST-GEN 1. 6.4 MAT-MORT 6. 6.6 tarmac -> MAT-ASPH 2, MAT-BAND 1, SUN-CARR 1. Step 8: size, grade, number and surface given, no conflict -> green.

## Example 2 (J0705): channel
Forms: Defective Channel Drainage. Entrance to service yard. Grated (Aco). Length of defective channel: 1.5. Grade D400. Surface: Concrete. Part required: 1.5 meters of aco 180mm deep 12 rapid-set mortar.
Steps: 1.3 channel. 2.2 "Part required" orders aco -> replace. 4.17 1.5 m rounded up = 2; 4.20 minimum 2 -> CHN-RUN 2. 4.21 CHN-GRATE 4. 5.6 one location, 2 m, no sump -> LAB-CIV-H 1. 6.1 SRV-UTIL 1, WST-GEN 1. 6.5 MAT-BAL 16, MAT-RCEM 4, MAT-SAND 4. 6.9 concrete, not a car park or road -> MAT-CREP 4. Step 8 -> green.

## Example 3 (J0243): other work, tanker
Forms: Contamination. Service yard B, soak away. Contaminated with: Sewage. Believed source: possibly adjacent foul water line leaking into soak away. Part required: Further investigation of nearby FW drainage to establish reason for contamination. Tanker to remove contaminated waste.
Steps: 1.4 other. 7.1 tanker: LAB-TNK-D 1; contaminated waste removed -> WST-GRS 4, WST-NOTE 1; investigation also asked -> LAB-DRN-D 1. Step 8: other work, the waste tonnage is an estimate -> yellow.
