Magagawa mo lang yan kung may detailed drawings ka na, pero kung floor plan lang siya, hindi mo talaga ma eestimate ng detailed.

pwede mo isa isahin. kunin mo surface area para sa paintjob. wall area para sa hollow blocks at palitada. more or less ganyan ka straight forward ang estimate. wall area para sa tiles. drawing ng balcony para sa ilang pieces ng steel bar and tubing.

categorize mo sila tapos sum up mo afterwards.

sa rebars kahit direct counting pwede di ba?basta ba meron ng structural plans&specifications (numbers and sizes of bars per column/beam/footing/slab etc)..much better to buy or borrow Max Fajardo's book on Estimate. thumbsup

ang pag eestimate sa rebars will depend sa design mo, kaya nga much better nga kung may detailed drawings ka na, Lets say na ang column mo has 4-16mm dia. bars. then ang footing to ground floor level is 1.0 meter and ground floor level to roof beam is 3.0 mts (kunwari single storey lang), so ang total height ng column mo is 4.00 mts. from footing to roof beam. So you will use 4 pcs- 16mm X 6.0 mts. bars.

Ngayon may sobrang 4 pcs. na 2 mtrs. ang haba kasi 4.0 mts. lang height ng column mo tapos 6.0 mts. ang market size ng bars. Pwede mo silang gamitin as footing bars mo.

Again, mas maganda kung may detailed drawings ka na or kahit idea lang ng structural design para ma estimate mo ng detailed.
