Specification Writing Checklist

1. CHECK-LIST
A) Land Survey:
a) Check the plot dimensions with reference to demarcation plan
b) Check the soil strata by taking the trial pits to ascertain the nature of sub strata
c) Check the ground slope and collect the details of ground level by proper survey
d) Collect the details about existing structures on plot, trees, any service lines such as
water line, drainage line, sewage line, electrical under ground/ overhead line etc.
e) Check the approach to the plot, any set off for road expansion etc.
B) Lineout Checking:-
a) When Schedule patti (Boundry) is fixed, Check level of Schedule patti with water
level. The center line marked with nailing should be properly denoted with
respective column number. Instead of Schedule patti this work can be done by
erecting/constructing brick massonary pillars of min. size 350mmx350mm finished
with smooth cement finish top.
b) Check all four corners, Peripheral measurements, Side margin and diagonals.
c) Check co-ordinates established on schedule patti with given center line drawing.
d) Make use of steel tape 30m/50m length, Nylon thread or binding wire.
e) For precise work and spread out area with uneven ground levels it is preferable to
make the use of total station for establishment of center line.
f) It is always preferred to check the entire centerline drawing and the line out twice
by different agencies to eliminate the mistakes & errors at very initial stage of
construction.
C) Excavation for Wall foundation and RCC foundation
a) Depending on nature of the ground, observations from trial pit decide the system of
excavation ie- manual, by mechanical equipments, by earthmovers etc.
b) Decide the location for stacking of excavated material (Reusable and material to be
cart away)
c) Collect the data of existing ground level for all column pits, wall foundation before
commencing the excavation work. After completion of excavation upto desired
depth collect information about excavation level.
d) Prepare the chart for strata classification with respective measurement for each
strata. If possible reusable filling material can be left inside the plinth area by
leveling the same.
e) In case of dewatering maintain proper log book for recording the data related to
Pump Horse power details, No. of hours & no. of days for which pump is utilized
and the activities carried out during /after the dewatering work.
f) While back filling of the pits or wall trenches ensure that the filling is done in
layers with proper watering and tamping/ramming.

2. D) Filling & Rubble Soling
a) Preferably use excavated gravelly murum for earth fill in plinth. Ensure that each
layer of filling should not exceed more than 450mm to 600mm depth. Provide
ample of water to plinth fill so that it will shirnk/ settle down. Provide optimum
compaction by proper ramming/ compaction with any hand/mechanical device.
b) In case of soling; preferably use stone blocks instead of flaky stones and lay them
systematically with even thickness. Fill all crevices and cavities with stone chips.
Cover entire soling surface with small, gravelly murum and sprinkle water to
penetrate small size murum in the gaps between stone blocks. Finally bring the top
surface finished with nominal filing & dressing etc.
to proper level to allow Plinth top PCC to be laid with even thickness.
E) Anti Termite Treatment
This should be carried out from nominated termite treatment agency. This
treatment should be provided at four stages as mentioned below
a) After completion of excavation for foundation pits & wall trenches for all inside
surfaces.
b) After completion of RCC work below ground and completion of plinth wall, But
before commencing backfilling.
c) After completion of murum filling in plinth and before commencing the soling
work/ Sub base PCC at plinth top.
d) After completion of entire building, dig a trench from periphery of the plinth of
size about 300mmx300mm and provide the final dosing of anti termite treatment
F) Plain Cement Concrete
a) Before laying PCC in foundation or at plinth top ensure that the base is properly
leveled and it is well compacted.
b) Use appropriate grade/ design mix for concrete and maintain the thickness as per
design
c) Make proper consolidation & leveling and curing for atleast 8 days
G) Reinforced Cement Concrete
a) Before casting of RCC footings check the center lines transferred in the pit with
reference to ‘Center line Drawing’
b) Once reinforcements are placed at its location for any RCC member check the
same with reference to ‘RCC design’ and confirm the reinforcement, sectional
size, side & bottom cover for the individual member.
c) Before starting the casting operation for specific RCC work such as RCC
footings, Slab, Cantilever structures, Any specially designed RCC item; ensure
that the same has been checked by RCC designer
d) Casting of the concrete should be as per the designed proportion or mix specified
by the consultant. Proper shuttering must be used for RCC work. All necessary
norms related to de-shuttering should be observed.
e) The concrete surface should be properly hacked once de-shuttering completes.
The curing period should be maintain properly

3. f) Necessary cube tests for concrete as well as reinforcement related tests should be
conducted and results should be recorded
g) Specific points related to Specific RCC member
i) Footings- Check its outer dimensions, confirm the shape ie- rectangular or
trapezoidal or square etc.
ii) Column- Orientation of column, Floor wise reduction of column size, location
of hanger column or floating column.
C-Masonary in Plinth For U C R/ R R Masonary Check stone quality for sharp
