2.2 Work Steps & Procedures:

2.2.1 EXCAVATION

The marking out for structures is to be carried out as per approved

drawings and necessary approval is to be obtained from GUPCO’S
engineer before proceeding with excavation works.
The depth of excavation for foundations will be as per approved
drawing.
The excavation to the required levels will be carried out either manually
or by machinery by making necessary precautions with regard to the
stability of the excavations, adjoining properties, any underground
utilities and the safety of workforce.
Excavated surplus material suitable for filling will be placed in fill areas
within the limits of the works.
Excavated material unsuitable for filling shall be hauled away and
dumped in to spoil areas as directed by the GUPCO’S engineer.
The excavation has to be approved by GUPCO’S engineer before
proceeding with further works.

General Requirements According to OSHA 29 CFR 1926.650 – 29 CFR 1926.652

1- The following specific site conditions should be taken into accounts for safe
excavations:

a- Traffic

b- Nearness of structure and their conditions

c- Soil

d- Surface and ground water - the water table

Rev. No.: 1 Rev. Date: July 2017
of New Mess Hall At Ras Shukier

e- Overhead and underground utilities

f- Weather

2- Before any excavation actually begins, the standard requires the employer to
determine the estimated location of utility installations: Sewer, telephone, fuel,
electric, water lines or any other underground installations that may be
encountered during digging.

3- No employee should operate a piece of equipment without first being properly

trained to handle it and fully alerted to its potential hazards.

4- The standard requires that a competent person inspect, on a daily basis,

excavations and the adjacent areas for possible cave-ins, failures of protective
systems and equipment, hazardous atmospheres, or other hazardous conditions.

5- Adequate protective systems will be utilized to protect employees. This can be

accomplished through sloping, shoring, or shielding.

6- Workers must be supplied with and wear any personal protective equipment
deemed necessary to assure their protection.

7- All spoil piles will be stored a minimum of two (2) feet from the sides of the
excavation. The spoil pile must not block the safe means of egress.

8- If a trench or excavation is 4 feet or deeper, stairways, ramps, or ladders will be

used as a safe means of access and egress. For trenches, the employee must
not have to travel any more than 25 feet of lateral travel to reach the stairway,
ramp, or ladder.

9- No employee will work in an excavation where water is accumulating unless

adequate measures are used to protect the employees.

10- A competent person will inspect all excavations and trenches daily, prior to
employee exposure or entry, and after any rainfall, soil change, or any other time
needed during the shift. The competent person must take prompt measures to
eliminate any and all hazards.

11- Excavations and trenches 4 feet or deeper that have the potential for toxic
substances or hazardous atmospheres will be tested at least daily. If the
atmosphere is inadequate, protective systems will be utilized.

The OSHA standards define soil classifications within the simplified soil classification
systems, which consist of four categories:

a- Stable Rock
b- Type A Soil
c- Type B Soil
d- Type C Soil

Stability is greatest in stable rock and decreases through type A and B to type C, which
is the least stable.

Stable Rock: is defined as natural solid mineral matter that can be excavated with
vertical sides and remain intact while exposed. (Example: granite or sandstone).

Type A Soil: are cohesive soils with unconfined compressive strength of 1.5 tons per
square foot or greater. (Example: clay, silty clay, sandy clay, clay loam)

Type B Soil: are cohesive soils with an unconfined compressive strength greater than
0.5 tons per square foot but less than 1.5 (tsf)

(Example: angular gravel, silt, silt loam)

Type C Soil: are cohesive soils with an unconfined compressive strength of 0.5 tsf or
less.(Example: gravel, sand and loamy sand, submerged soil, soil from which water is
freely seeping.

Excavation Protection Systems:

There are two basic protective systems for an excavation and trenches:

 Sloping and Benching Systems

 Shoring Systems

The protective systems shall have the capacity to resist without failure all loads that are
intended or could reasonably be expected to be applied to or transmitted to the system.

1. Sloping and Benching Systems:

 Sloping Systems:
Maximum allowable slopes for excavations less than 20 feet (6.09 m) based on
soil type and angle to the horizontal are as follows:

Soil Type Height/Depth ratio Slope Angle

Stable Rock Vertical 90 deg.

Type A ¾:1 53 deg.

Type B 1:1 45 deg.

Type C 1½ : 1 34 deg.

Shoring Systems:

Shoring is the provision of a support system for trench faces used to prevent movement
of soil, underground utilities, roadways, and foundations. Shoring is used when the location or
depth of the cut makes sloping back to the maximum allowable slope impractical. Shoring
systems consist of posts, wales, struts, and sheeting

2.2.10 False Ceiling:

Gypsum Ceiling

1- Measure the ceiling starting the one end along a wall perpendicular to the joists.
2- Find the joist that's closest to being 8 feet from the wall, without being further than
that.
3- Measure from the middle of the joist to the wall.
4- Use your razor knife to score and snap a piece of gypsum board at that length, running
the blade alongside your t-square to keep it straight.
5- Set up two ladders, one by the starting wall, the other under the joists to which you
measured.
6- With an assistant, hold the gypsum board up to the ceiling, with the cut end facing the
wall and the uncut end lining up with the middle of the joist.
7- Shoot drywall screws every six inches or so along the edge of the board where it is
under the joist.
8- Do the same for the rest of the joists above the board. (You will be able to judge the
positions of the joists behind the board based on where they come out from the side of
it.) Make sure to completely sink the screw heads below the surface.
9- Hang the rest of the boards in the same manner, positioning them end to end, in
courses, always meeting at the joists.
10- Stagger the positions of the board between courses, so there are no four-way
intersections.
