02/100, a wednesday

 today i went for a run, on my own as i had some work to finish up..

it was nice, and i ended off, lying down on an inclined bench, facing the HSBC, DBS and Fullerton building.

unprotected opening can be best understood by doing a calculation in sequence. Started from the 

1. assume rectangle

2.enclosed rectangle

3.Unprotected opening area

4. percentage of unprotected/enclosed rectangle

this inclined bench, when i sat on it, i felt so at eased. it was a good moment in touch. Employed, with my namorada, and around chinatown area, and with a vespa.

Second month of 2021. 100 day challenge 01/100

 Lets do 100 days of blogging

Actually this is inspired by a patreon ukelele person that i follow. hers of course is more challenging at a song a day i think. crazy.

For me, hopefully it ll be easier. Each day is a brand new start. No looking back.

Ukelele class today at 7.30pm, so have to be efficient to finish up the work.

L n i started online counselling, i used to think i could express myself and am eloquent, but i find this really helps. Having someone to paraphrase and restructure ones thoughts. That author i started reading a little, we write so as to savour life twice, Anais something,  and about the modern woman and her compatibility with the sensitive man. So many thoughts go through my head these days, on whether this is the right career for me, with the many pop up windows on government grants on the various courses. And of course, how my future will look with me alone. Without my love.

Deep breath\ there now.

Everything s going to be alright.

Better to blog at night i think

Today went by quite fast, it was good to sit in for the feasi for pka, first qn E ask was the sectional height of office-->affects placement of office-->clearance of ramp above-->min length required for clearance-->entrance of it. Then S commented on the layout, mainly mastersuite toilet window, and light in. Thickness of walls at 100mm will suffice. Then ukelele at night. The calculation of the unprotected was quite a handful, the different configurations. It was interesting, planning ahead for certain notes of the Uke to play it smoothly. Even rode today, though there was some indication that it might rain.

Feasi brain exercise like a soduku

 this one is factory

large " one room" spaces. understanding more about smoke purging and compartmentation now...

if there is anything that can be convincing about a layout, it is a requirement. if one wants to do good design, one needs to understand the requirement well to support ones' case. As when a client has to choose between aesthetics and money. the clear answer is money. unless statutorily required. 

A current example is now, doing a layout of a giant factory space of about 25,800m2, 3 storeys, each story is  8600 sqm. the ideal is one big space, however, think of the urban and human emotion when one looks at this big black box. unreadable, lack of any warmth, however if we can break it up into smaller blocks this would give rise to many opportunities of roof terrace, interlocking shade and shadow... Spotted in the brief, is a requirement for Smoke control of natural means. However, in the 2018 scdf, 7,4  says engineered smoke control is needed when aggregate floor area >5000sqm. here if we keep it to one giant space, 8600 is obviously > 5000 sqm.. and if this NV requirement is necessary, it would make more sense to break the giant massing into min 2 parts.

*** sala! Instead of the regular chapter3 for compartment, compartment for warehouse has a separate table at 9.8A, and smoke requirements in 9.8B where allowable area is much larger!

eg storage warehouse w sprinkler & vehicular ramp is 9000m2, n w/o is 6000sqm

For previous moh feasi one, after i presented my option 2, from a money perspective, mine was more expensive as toilet stack is further away from the entrance, hence longer and more piping cost. and that was it. probably 3 hours worth of thinking and doing just put away in less than a minute of thought and comment.

the 3 sisters. compartment, if exemption is to be have, smoke and sprinkler have to be fulfilled more.

-note compartment can be exempted ( saving of roller shutter cost?) if:

1.sprinkler can be complied;  

2.smoke (7.4) n specific use cases compartment(9.8.3)

Feasi Discussion

Thoughts after dicussion:

1. The deciding factor is not the bulk of it ( eg Facade)itself. 

2. Placement of driveway wrt services that need access, for eg: ESS/CSR, note ht is 5.7m, cable chamber is 2m, then powergrid is 3.6m above.

3. Toilet location for sanitary stack, the closer it can be to the entrance the better, shorter pipework, save money

4. Detention Tank and location should be considered wrt lowest invert level of perimeter drain, so that it can be gravity feed. If not a pump will be needed, expensive n need maintenance.

5. Existing Hydrant location? if it is too far, pressure is not enough, a pump room may be needed

6. For steelwork expression, if smoothness is not required as per specifications, fire rated board not needed, can be vermiculite, and thus expressed.

7. For ESS, usually not steel as it needs 4hr fire rating, so RC is better.

8. As it is 3 storey, risers needed esp electrical, location usuallly at s/c or wc.

Qns ask by archi boss:

-Elevation needed surface area, after calculating unprotected opening , for costing purpose of fire-rating

-Facade wise, columns at the back

-Brief says need 9 months till completion, M&E says ESS can be done in 6 months, 1 month between plan and approval.

 How is this one different: ( on hindsight what i should have highlighted for scheme 2)

-Facade expression, master & servant, healing garden for cp

-FEA is independent, as loading is 30 tonnes the material has to be specific, if it is in a garden location, the natural pathway theme could be compromised

-location of ESS can be nearer to the accessroad

A&A

From Previous Note-Taking: 

Types of Steel

-Mild steel, stainless steel, galvanized steel

Labels:

Not "construction drawing" but " working drawing", as architect is the contractor administrator, not the QS

______________

3.9.2 SCDF:

Fire Door, in the event of an EM lock, " Electromagnetic device". activated by smoke detector or building alarm. Note Fire Alarm needs power, and there is the auto(smoke detector) or the manual type.

New Team

 started w doing construction drawings, for an existing project. a cafe layout, plans. adding gridlines. Actually it is not difficult, but not sure why i couldn't get it right.

*Post Exercise Cabinetry*

-Gridlines to be lighter, and always dimension

-Panel lines, no extra frame, note panel to be in front of structural frame

-no overlap lines

-drawer detail, back board with drawer container detached from it, and intermediate member between the front pulls. note overlap region necessary to prevent drawer from sliding backwards

*Post Exercise larger factory*

-Annotation, label ingress/egress, indicate building line above, mezzanine above, dimension of FEA

-possible for 

1)CSR to be on top of transformer & Powergrid on top of CamberChamber, but total ht would be 5.7m

-for vehicles, that are 3.0x7.5m 90 degrees reverse parking,  would need 9.0m distance behind

-lorry min clear clear height 4.2m

-generic column size 800x800

-aircon ledge is $, always aim to have min 5% of min 150sqm

-GFA efficiency good value is 70-80% and Saleable efficiency is 120-140%

-"Ancillary office": is mezzanine floor and 

-"Other Ancillary": M&E ( only rooms), lift lobby, staircase, FCC

-note mezzanine floor above 24m need to have driveway access but then efficiency will drop because of added liftlobby

New team feasi

Factory feasi

good to have:

-Ramp at 1:9

-calculate efficiency of building

-beyond 24m, cannot have mezzanine

E must have:

AC ledge to be 5% of area

E ideas:

-corridor linking to lobby, open to sky, possible to be gfa free

-"canteen" as a "fine dining space"

-sky terrace: difficulty in how to make it common

-setback from boundary line for putting sub structure and formwork; how to plaster and paint?

Comments upon looking at feasi

-FEA along external roads, have to be after drain and pavement

*note discussion w C&V, proximity of industrial stairs to be FEA does not need to  be 18m, vs residential stairs that needs to be. If sprinkled, 50% of building can have indirect discharge, but has to be 5m from building eaves.
