House Constuction [Merged]

[papi smith]

Sariling sikap kasi ito Sir Max, so mga taga rito sa amin na mga old school workers ang gamit ko, my mistake was to trust that they knew what they were doing, hindi pala man lang tinignan ung plano so may mga dowel where they were not needed and none where they should be. Ngayon nakatutok na ako. Neighbor ko kasi ang aking consultant and kung maswertehan lang na available sya. So no need to worry pala ako na the dowel exposed to soil will rust enough to creep inside my post and eat my column reinforcements. [emoji26]

No worry sir kung sa dowel lang concern mo. Mas nakakaworry kung yung footing rebars mo hindi nila inangat ng 75mm (3") sa lupa. I seen footing rebars naiwan sa ilalim at binuhusan sa ibabaw [emoji16] dun sa isang project ko na mat foundation. Hinukay namin mga 4 meters depth sa adjacent bldg with proper shoring support naman.

Thanks Sir Max, Yung footing ko I made sure we placed 3" spacers, which reminds me na dapat pala ma check ko if I still have spacers, baka short cut nila at pakyaw kasi 🤨

Ask mo sa mga hardware store baka meron. Nagawa nalang kami kaya dapat yung nagawa mga 400 pcs minimum a day para hindi talo. [emoji16]

Salamat sa guidance Sir, Kung Wala sa hardware, papagawa na nga lang ako

Here I am again masters [emoji3] May I hear your opinions regarding pouring the second floor slab in sections? I reckon, we can pour the entire second floor in 6 working days at the most using just a bagger concrete mixer. This is a backup plan if the cost of ready mix will be prohibitive due to subdivision restrictions, mainly big concrete mixer trucks and pump crete are no longer allowed. That leaves me with small trucks and probably a hose requiring additional labor on my part. I've done the math and there is a safe 20% savings on manual pouring. But how are the pouring sections divided? Or where should I "splice"? Thanks

have you considered hiring more mixers, so's everything can be finished in one day?
i'm no engineer, and i do not have any idea on whether such one-day adventure is structurally acceptable.
i'm just looking at the time aspect.

[papi smith]

Yes doc, the cost would just come near the ready mix option and not worth the additional effort

What's your volume & manpower load? Monolithic pouring is always better than 1 w/ breaks & splices. Try searching a portable rental pump.....or Doc's idea. These reduce time & effort. For 1 bagger mixers, focus on mix consistency esp water content. The lower, the better.
If you can't do the 1 go option, discuss w/ your structural designer & pre-identify the cut sections. He'll point those w/ the lowest stress & moment exposure.
Check the forecast, choose a comfy non-rainy day, or better....do the pour from dusk to dawn (more about temperature than traffic). Temperature significantly affects concrete curing and ultimately its strength. Too hot? You'll get a hastened & uneven cure start where water loss is abrupt. This causes cracks and weak points.
Pouring is a critical activity. Think no going back once done. Quality must be primary, cost secondary.

Try to rent concrete lifter (portalift)it is much easier compare to manual laborer. You can finish that in one day. Did you compute total cubic needed?

Thanks Sir Max, I was able to get a small truck provider, I was surprised that the cost per cum is P5,500. I was expecting P3,500 as are most posts at olx. The manual pouring by section by my estimate is P3,500 max. But the last sentence of Sir Travs really got into me, so no choice but to go ready mix [emoji2]

You should also consider pumpcrete rental about 22k unless the price of 5.5k are inclusive of this.

Sir Max, pump crete is 15k + mix of 5k/cum for a total of 25 cum max my estimate, ganito na ba talaga ang going rate o baka dumaan ako sa agent kaya masyadong malaki?

Hmmmm. Agents? Bookings are best direct to batching companies. Ideally, one that's close to your site. Factor in travel time & traffic. 25cu. can be over in a coupla hours...or much much longer.

Guys quick question. Is there really a surety bond to be paid to DPWH for altering the top of their drainage into a ramp?

They're asking for what seems like 20-30% of the cost of the drainage section as a surety bond. Non refundable daw. 1st time I've heard of a bond that's non refundable.
