### **Common**

#### *Objective*

1. Seminar Chap 9: offer, acceptance, consideration, intention to create legal relations, certainty, legal capacity, free consent, legality of object > answer = D
2. Seminar Chap 11 - Discharge of contract: frustration, performance, breach, consent. Due to consent of both parties, contract is discharged > answer = A
3. * **UBBL 7 (3)** "...has died or become bankrupt or cannot be found or has been deregistered from the register or for any other reason ceased to practise, the owner or occupier shall as soon as practicable appoint another principal submitting persons or submitting person to act for him and to submit adequate evidence to the local authority of the circumstances *[i.e. the 2nd Eng]*".
	* **BEM Circular 008** clause 3.5 (c) "1st Eng...informed the local authorities that he/or it was withdrawing from the work"
	* >answer = uncertain depending on interpretation (A/D). UBBL 7 (1) agrees with BEM Circular 008 for 1st Eng, but only applies to work not commenced as stated in 7 (1b), whereas the question stated work started. Therefore we can assume 7(3) to cover the other eventualities i.e. work started.
	* >However in most practical cases, regardless whether work started or not, 1st Eng i.e. PSP/SP is responsible until end [Pending confirmation from BEM Exam committee]
4. **This question was memorised as either of the 2 following scenarios, thus yielding different answers:**
	* *Scenario 1: contract to deliver computer and pirated software* >answer = D (Contracts Act clause 25 - agreements void if consideration and object unlawful in part)
	* *Scenario 2: contract to deliver computer and legal software, but supplier give pirated* >answer = A/C (in this event, a legal contract is not void, but rather considered breached, due to delivery of the wrong item. If the supplier refuses to deliver the correct goods, legal action can be taken)

### **Civil**

#### *Objective*

1. * Table 2.5 MASMA **2-7**
	* Q=CIA/360=IA/360 (50%\*Cjungle+50%\*Cdetention pond no outlet)
	* = **4.5m3/s**
2. * MSIG 3 pg 25
	* Peak Factor = 4.7 (PE/1000)^-0.11
	* Peak Flow = Peak Factor x 225L x PE (day)
3. * Based on limited info from question, we summarise:
		+ Length of distribution mains (km)= L1
		+ Length of reticulation pipe (km)= L2
		+ Height of tapping point on reservoir from reservoir base (m)= Htap
		+ Residual Head at tapping (m) = Ptap
		+ Residual supply head (m) = RSH
	* ~~During normal operation, find residual supply head (RSH) required at development (compare with min RSH 7.5m):~~
		+ ~~30+Htap+Ptap=Pipe Losses+29+RSH~~
		+ ~~30+Htap+Ptap=3L1+2L2+29+RSH~~
		+ ~~RSH = 30+Htap+Ptap-(3L1+2L2+29)~~
	* During minimum water level operation, assume min RSH>7.5m find Pmintap:
		+ 30+Htap+ Pmintap=3L1+2L2+29+RSH
		+ Pmintap=3L1+2L2+29+RSH-(30+Htap)
	* Min water level/bottom water level (BWL) = 30+Htap+ Pmintap (in RL)
4. Pg 77 MSIG 3, Appendix A (question gave true/false statements asking about the specifics method)

	* a) true
	* b) false *(sand replacement is not to measure the weight of sample but volume of sample)*
10. * a) false
	* b) true - stone pitching manning n>concrete, therefore v < concrete. since Q = VA, stone pitched drain capacity<concrete
11. Dry density, ⍴d= mass of solid/total soil vol=ms/v
	* At max ⍴d,100% compaction achieved =20kN/m3
	* 90%⍴d = 18kN/m3
	* Weight of soil required,ms=18x20,000=360,000 kN
	* Since weight of fill is similar, min V fill from borrow hole= 360,000 /17.5= 20,571m3

31. * I = uniformity in all orientation (true)
	* II, III, IV = true
32. * I, III, IV, V true
	* II for torsion
33. I, II true, III false
