2. Lighting

2.1.1 Calculation Formula for Illumination level :

SMUNFnE ××××

=

E: Average Illumination level (Lux) on desk (FL+700) n: Bulb number/Lighting fixture F: Flux (Lm) N: Number of Lighting fixture U: Illumination Factor (%) M: Maintenance Factor (%) S: Room area (m2)

2.1.2. Procedure for lighting calculation

2.1.2.1. Make calculation from : refer to "example"

Example:

Make condition by you:

• Office -> FL40Wx2 Louver type / 500Lux

• Office area -> FL40Wx2 V type / 300Lux

• Factory -> MH 250W / 200Lux

2.1.2.2. Put in room name

2.1.2.3. Choose lighting type

- Incase have condition by Owner, follow requirement

- No requirement, choose VNKD standard

2.1.2.4. Illumination level E (Lux)

- Incase have condition by Owner, follow requirement

- No, requirement, choose VNKD standard

2.1.2.5. Flux F (Lm)

- Choose in VNKD table

2.1.2.6. Maintenance factor (M)

- 0.7 fixed

2.1.2.7. Bulb number

- Depend on lighting type

2.1.2.8. Measure room area

2.1.2.9. Illumination level U

- Choose from VNKD standard by each room area

2.1.2.10. Calculation:

n x N = (E x S) / (U x M x F)

N = n x N / n

2.1.2.11. Adjust lighting number by room balance

2.1.2.12. Calculate final illumination level

12. Short circuit current

If short circuit current happened in electrical system, very big current (kA) is caused in primary line of short circuit point, then equipments are burnt out by heating, so we have to install CB or LBS w/ fuse to cut off this trouble current, not only for over current.

Any CB and LBS have several breaking capacity, we have to select CB to have applicable breaking current after calculate for short circuit current.

15.1.2. When install wires or cables in pipe , shall not give any damage on insulation material

caused by slip resistance and pulling tension, so we have to choose applicable pipe size

for wires and cables as follows :

• Min. pipe bend:

o Pipe bending radius for wire > pipe size x 6 times

o Pipe bending radius for cable > pipe size x 10 times

15.1.3. and also we have to consider, allowable current of wire / cables in pipe, item 14.5.3.

15.2. Applicable pipe size for wire

15.2.1. Under general condition

• Total bend < 2700

• Length < 30m

• 32% x Sp ≥ Sw

15.2.2. Under easy condition


• Length < 50m

• 48% x Sp > Sw

1. ESTIMATION

1.1. Estimation means "count the all material and equipments" from drawing and specification in this parts.

1.2. We have 2 cases for estimation. One is for quotation, the other is for purchasing.

1.3. Estimation is very importance work. If mistake, such as lost the expensive material in quotation, after get project, Company lost so much money. If mistake, such as to put high unit price, very much quantity to quotation, we can not get project, also Company has big damage. So you have to do estimation very carefully according to following procedure and notes.

2. GENARAL PROCEDURE AND NOTE FOR ESTIMATION WORK

2.1. Customer's inquiry

Estimation

Page: 135/198 2.2. General procedure and notes

5- Shall make plan :

• Time schedule

• Decide estimators and divide the work among them.

• Arrange the document and take copies such as needed specification, condition, Q&A, drawing for estimator and inquiry to manufacturer

6- Order to estimators

7- Make inquiry to manufacturer

Note 1: Shall guess and make bill of quantity (BQ) for materials

Note 2: Shall request manufacturer's proposal as option

8- Give inquiry to purchasing manager

9- Measuring and counting

Note 1: Shall use "Estimation Form" refer to 3.1 EST-01

Note 2: Shall follow "Estimation procedure for each work"

Note 3: Don't use CPU, shall write down by hand.

Note 4: Shall count and measure correctly, don't add any spare for each measuring

Note 5: Shall check symbol on drawing by yellow pen immediately, after counting or measuring

Note 6: Shall estimate for each work such as lighting work, telephone system, others and for each building if have

Estimation

Page: 136/198

Note 7: Shall check carefully for "Scale" of each drawing. If mistake scale, estimated quantity is big different. Don't use scale for all materials, mainly use civil dimension on drawing.

Note 8: Don't forget to measure for vertical up and down, decide length of up and down before measure

Note 9: Shall refer to concerned drawing, such as single line, detail, and specification.

Note 10: Shall image the site work and then counts auxiliary materials, not to be indicated on drawing such as foundation, support.

Note 11: Shall recount and re-measure for expensive materials, such as expensive light, big size cables, local panels and small power equipments.

Note 12: Don't mistake "written position" and calculation of number on estimation from. Shall re-calculate.

Note 13: Shall check totally, such as which are there any missing materials or not, quantity enough or not by feeling

Note 14: Shall consider VE (value engineering) and your idea for reducing price during estimation

10- Making draft estimation

Note 1: Shall write down carefully to "Draft estimation sheet" refer to 3.2 EST-02 from "Estimation form".

Note 2: Shall check one by one to each item, compared with "Estimation form" by yellow pen

Note 3: Don't forget special works such as application, testing, commissioning, crane, excavation, special transportation.

Note 4: Shall write down out of scope work, such as foundation, fence, pit, manhole, control panel then put "out of scope" clearly in price column

Note 5: Shall write down equipment with "supplied by Owner" also

11- Checking the manufacturer's quotation

Note 1: Make "Comparison list", refer to 3.2 EST-03, for price and condition by purchasing staff.

Note 2: Make "manufacturer's specification sheet", refer to 3.3 EST-04 by engineer.

Note 3: Generally many manufacturers have many mistakes, such as:

- For Bill of Quantity: set, unit, number, pcs, m, others

- For condition: quotation validity, delivery date, payment, guaranties period, others...

- For specification:

• Simple mistake

Estimation

Page: 137/198

• Misunderstand

• Own proposal instead of requisition (not match with original specification

• Others

So check carefully, if have difficult for understanding, confusable, even small mater, don't judge by your self, ask to technical manager.

Note 4: For mistake, misunderstand, not enough or missing documents and questions shall request as soon as possible from purchasing staff.

Note 5: After make "Manufacturer's specification sheet" and "Comparison list" shall discuss and judge for detail of manufacturer's data with manager meeting.

Note 6: Also examine manufacturer's proposal witch available to use or not, in manager meeting.

12- Input to CPU

Note 1: Shall input data from "Detail estimation sheet" and manufacturer's quotation (or comparison list) to CPU carefully, such as:

- Quantity

- Unit price (Unit price shall be input for net price or manufacturer's quotation price)

- Material size, specification

- Lost item

Note 2: After input and print, shall check one item by one by yellow marker pen by CPU operator

Note 3: Second and third check

- Not to be lost or too much

- Application, testing, commissioning, crane, excavation and others

- Confirm out of scope work

- Unit price number

- Amount price of each work to be reasonable or not by engineer's feeling

Note 4: Estimation soft: refer to ...................................

13- Make "Budget sheet (estimation)" refer to 3.5 EST-05

Note 1: Print out summary direct cost (material, sub-con, expense) by CPU

Note 2: Check and examine each item cost which is reasonable or not by

Manufacturer's quotation for equipments

Feeling, experience, for cable, pipe, rack and others with managers

Check site condition for expenses together with managers

Estimation

Page: 138/198

14- Calculate "Expense and SV fee"

Note 1: Discuss expense with manager

Note 2: Refer to 3.8 EST-08

Note 3: t6VK standard factor

15- Make "Condition of quotation"

Note 1: Condition means " To do clearly for scope of work". Total amount and Condition are most important for quotation

Note 2: As Vina-Kinden standard, refer to "Condition of Quotation ...................", refer to 3.6 EST-06, 3.7 EST-07. Select and add for each item very carefully.

Note 3: If have different point compared with Owner's specification, make comment of reason.

Note 4: Proposal / Deviation : if have good idea what is able to reduce price, make proposal as option.

Note 5: Shall make above documents before min. 1 day of submitted date

16- Submitted amount shall be decided by General Director

17- Make Submitted detail

Note 1: Decide Submitted Unit Price by Manager or Director.

• Up same factor to all items

• Special factor for same equipments

Note 2: Check submittal documents:

• Set number

• Quotation

• Condition

• Drawing

• Requested documents

• Catalogue

Note 3: Check customer's official name

Note 4: Check Quotation number and Date
