+# 1. Goal
+Calculate the hire fee of a mobile crane job. A quotation program calls the
+calculation before it sends a quote to the customer. The program needs the fee
+and one reason code for each request.
+
+# 2. Open questions
+None.
+
+# 3. Context
+- Interface {{P}}IF_CRANE_HIRE exists in package $TMP. It is active.
+- Read the interface. It contains the types, the reason codes and the signature
+  of the calculation method. Use the names of the interface.
+- The method receives the working radius, the load, the ground type and a flag
+  for a road permit. It returns a reason code and a fee.
+
+# 4. Contract
+- Create the class {{P}}CRANE_HIRE_CALC in package $TMP.
+- The class is public and final. It has a public constructor without parameters.
+- The class implements {{P}}IF_CRANE_HIRE.
+- Do not add other public methods.
+
+# 5. Business rules
+Apply the rules in this sequence.
+1. If the radius is less than 5 or more than 60, return the radius reason and a
+   fee of 0.
+2. If the load is less than 500, return the load reason and a fee of 0.
+3. The crane has a load chart. The maximum load depends on the radius:
+   radius up to 10 m: 12000 kg, up to 20 m: 8000 kg, up to 30 m: 5000 kg,
+   up to 45 m: 3000 kg, up to 60 m: 1500 kg.
+   If the load is more than the maximum load for the radius, return the capacity
+   reason and a fee of 0.
+4. Remove the leading and the trailing spaces from the ground type. Convert it
+   to upper case. The ground type must be ROAD, GRAVEL or SOIL. If not, return
+   the ground reason and a fee of 0.
+5. Calculate the base fee: the radius in metres multiplied by 15, plus the load
+   in kilograms divided by 100 and rounded down, multiplied by 5.
+6. Multiply the base fee by the ground factor and divide the result by 100. The
+   ground factors are: ROAD 100, GRAVEL 115, SOIL 135.
+7. If the road permit is required, add 250 to the fee.
+8. If the fee is less than 300, set the fee to 300.
+9. Return the OK reason and the fee.
+Round each multiplication by a ground factor to the nearest whole euro. Round
+halves up. The fee is a whole number of euros.
+
+# 6. Constraints
+- Release target: ABAP Platform 2025 (SAP_BASIS 816).
+- Coding standards: Clean ABAP. Method length below 40 statements. No global
+  variables. No comment that restates the code.
+- Out of scope: do not change {{P}}IF_CRANE_HIRE.
+
+# 7. Acceptance
+- The class is active and has no syntax error.
+- The hidden tests pass.
+- Write your own ABAP Unit tests for the class.
