# Administration and Contracts

To participate in **Great Works**, you must allocate [Famous Buildings](https://city-whitepaper.gitbook.io/reality-rush/advanced-gameplay/famous-buildings) to your Great Work Board. However, these buildings require contracts to work on the project, and there is an administration fee applied to each Great Work attempt. Proper planning is essential to maximize your rewards and avoid unnecessary costs.

***

#### **Contracts**

1. **Cost per Building:**\
   Each Famous Building on your Great Work Board requires a **contract** to participate. The contract **cost between $RRUSH 25 to $RRUSH 5,000 per building.**
2. **7-Day Contracts:**\
   Contracts are purchased in **7-day increments** for each building you place on your board.
3. **Contract Loss:**\
   If you **merge** or **burn** a building while it has an active contract, the remaining contract time and associated cost are lost. Plan your board and merging strategy carefully to avoid unnecessary losses.

#### **Administration Fee**

In addition to the contract cost, there is a **15% administration fee** applied to the reward of each Great Work attempt. This fee is deducted from the total reward if the project is successful or not.

**Example Calculation:**\
For a **Level 5 Great Work** with a reward of **3,000 RRUSH**, the administration fee would be:\
**15% of 3,000 = 450 RRUSH.**

***

#### **Where the Fees Go**

All contracts and administration fees are pooled into the **Great Works Reward Pool** to sustain the ecosystem and ensure long-term rewards for players.

***

#### **Examples**

**Example 1: Single Epic Building**

* **Board:** 1 Epic 5-Star building.
* **Attempting:** Level 10 Great Work.
* **Reward:** 10,200 RRUSH.
* **Costs:**
  * **Contract:** 2,500 RRUSH.
  * **Administration Fee:** 1,530 RRUSH (15% of 4,300).
  * **Total Cost:** 4,030 RRUSH.
* **Success Probability:** 70%.
* **Expected Reward:**\
  10,200×0.7=7,140 RRUSH.
* **Net Expected Reward:**\
  7,140-4,030=3110 RRUSH.

💡 Using more buildings would increase costs and could turn your net reward negative. Plan carefully!

***

**Example 2: Multi-Building Titan Board**

* **Board:** 2 Titan 2-Star buildings + 1 Legendary 4-Star building.
* **Board Grade:** Titan (majority grade).
* **RP Power:** 8,000,000.
* **Attempting:** Level 11 Great Work.
* **Reward:** 15,600 RRUSH.
* **Costs:**
  * **Contracts:** 1,500 + 1,500 + 1,000 = 4,000
  * **Administration Fee:** 2,340 RRUSH (15% of 15,600).
  * **Total Cost:** 6,340 RRUSH.
* **Success Probability:** 73%.
* **Expected Reward:**\
  15,600×0.73=11,388 RRUSH.
* **Net Expected Reward:**\
  11,388−6,340=7,428 RRUSH.

💡 You might optimize further by reducing the number of buildings to lower contract costs while maintaining success rates.

***

#### **Strategic Considerations**

* **Optimize Board Composition:** Using high-grade buildings with fewer contracts can improve profitability.
* **Choose the Right Level:** Attempting lower levels may result in lower rewards, but the reduced costs and higher probabilities can yield better overall returns.
* **Calculate Costs vs. Rewards:** Always ensure your **expected reward** exceeds your **total costs** to avoid losses over time.

Mastering contracts and fees is key to becoming an efficient Great Works strategist!
