Client: Eagle Hills.
Scheduled the project/program activities within budget and time constraints; directed a highly-skilled team,
and updated the logistic and cost plan in accordance to the site requirements. Executed all works on the
ground in accordance to the project specifications, quality, and health & safety plan.
Reviewed the method statements, implemented the best construction methodology as well as the inspection
and test plan in accordance to the project specifications. Coordinated with the supervisory personnel,
subcontractors to resolve work procedures and construction problems.
Liaising with the Technical Department to ensure smoothening of technical submittals issuance. Led a weekly
subcontractors’ progress meeting, and submitted risk assessment for new site activities.
Ensured all materials are requested ahead as per the settled plan.
Proper delay impact reporting, registration & notification any subcontractors’ shortfalls.
Evaluated the new awarded subcontractor packages from technical, site execution perspective.
. Enabling packages: The enabling package on my recent project on Qatar was included
on our contract; the company decided at that time to divided on several packages, & not
to be awarded to one enabling contractor due to the cost limitation. I succeeded to plan
& execute two Plots enabling packages managing three to four subcontractors
(Excavation, Pilling, Dewatering, shoot creed). while on the same time allowing the water
proofing & concrete works for the raft of the building to start partially.
2. I’ve cast during my experience 5 buildings rafts; Two of them was managed completely
by me as of Methodology, & required needed preparation.
3. Concrete cycles would be differentiating from one project to another according to the
provided design & area. But in general, for the high-rise building getting the slab on six-
days cycle is mandatory. The most affected part is the availability & competency of the
resources “Mainly the Manpower” . I have experimented here on Qatar due to the
unavailability of the skilled manpower at early stage when I joined GCT that I was on a
position to look for another solution utilizing different subcontractors from the market, till
getting the best craw.
4. Defining Critical Design Problems at early stage on a project could save a bunch of time
& headache: I’ve an issue on my recent project that the total connected required
electrical load is higher that the Design allocated load by the Designer, & so on by the
approved authority required transformers & Switch gears. The exercise of defining the
load shortages was held at early stage on the project throughout my sharp follow up to
get the actual Single Line Diagram approved by the Engineer. At the design stage the
engineer has missed all the kitchen equipment’s required loads on his original design
which lead us to a significant variance on the total connected loads. the insistency to
have the engineering part clear at early stage on the project does eventually save time.
Meanwhile I was being forced to work on site on Out of Sequence way & force my
subcontractor to do so by pulling all the wire & fixed all Apartment DBs, start the ceiling
suspension works. & only hold the areas which included the Submain DBs “Back of
house electrical rooms” & some main cables in addition to the bus bar & the LV, MV
room till the new single line diagram being approved from the authority.
5. Having my experience enabled me to allocate another design issue which was part of
One of the building lifts which was allocated for the Roof Penthouse area & only open at
that floor. Earlier on the Sant Regis project, I had one panoramic lift which is as well was
designed to be opened only at roof level “Restaurant” & Ground floor. As per civil
defense the elevator must have an emergency exist at the least each 11 meters, for
which we added the emergency doors for that project “Sant Regis”. On this project the
situation was similar, but the hardest issue is that if we added the emergency doors on
the typical floors, that could affect the architectural layout of the apartments as the lift
wall was inside the apartment layout on the typical floor. On this case, I was being able
to allocate this issue at early stage & communicate both the Engineer & the lift supplier
GPS system for the surveying purposes. The core wall Main Corner surveying
points on the Landmark Project was being allocated by A GPS system, involving
this system on the cycle was a new procedure, which I’ve been familiar with.
* Inclined & Heavy structure Shuttering & Back propping Methodology: We have
fabricated A Steel Truss for each of the transfer heavy walls to be acting as a
back propping to the structure as an alternative way to the usual back propping
methodology since the weight of the structure was too heavy. The fixation of the
trusses in addition to the Jacking Up system using a 300-ton hydraulic jacks was
a unique practice.
* Shortening monitoring system for vertical structure throughout fixations of Strain
gauges inside the vertical structure in order to monitor the behavior of the tower
up to 20 years.
8. Using the structural external strengthening methodology: On the Landmark project, the
client has added two floors to the podium levels on a later stage which lead us to
strengthen the columns & the podium ground floor beams by the VSL team “Design &
Execution” in order to take the additional loads of the new structure. the Addition of
carbon fiber reinforced polymer (CFRP) for the columns were executed in addition to the
enlargement of the ground beams by using of steel & Pumped grouting materials. Other
external steel plates methodology was being used & supervised by me on another
project.
9. The exposure to different types of Façade & Glazing such as Unitized, Curtain, Stick,
Window, GRC, Stone, & Aluminum cladding though my experience has got me a solid
base for the façade work from methodology of fixations to the different types of
insulations, & required coordination with BMU or Façade lighting system.
10. Working along with different countries Authorities handing over processes & systems
have added a lot to me, as well as dealing with different Areas’ developers rules.
11. Having the awareness of the cost & Budget allow me to save much throughout
progressive & accurate monitoring to the In-house Materials selection, consumption &
manpower proper distribution as a CM.

Planning & Control Part:
1. If The baseline schedule still on the initial stage & was not approved yet. I would insist
to be reviewed thoroughly from the Sr. CM. & PM, as most of the baselines which I
came across were being prepared on the post tender stage on the head office without
much involvement of the site team. Which could make a back fire later on due to the
improper links on any of the EOT claims, in addition to the weight(Loads) distribution
of each activity specially for MEP as it might affect the cash flow later on if the
consultant insisted to link both the planning & the invoicing together.
2. Any study on the impacted updated program for any of EOT submittal, must be made
in coordination with the Sr. CM or PM along with the Planning Manager/Engineer in
charge.
3. Review of the weekly & monthly reports prior to submission in order to dilute or hide
any of the concurrent delay on one way or another.
4. Milestones for the main subcontractors’ work packages to be initiated by The Sr. CM.
5. Notifications of delay to be issued to the concerned delay subcontractors as per
Subcontract Conditions In a proper & logic manner. All should be recorded officially as
per the correct communication channels.
6. Proper recording for any of the Engineers delay submittal “RFI, MATERIALS, SHOP
DRAWING, etc.” as per the contract procedure.
7. Proper recording for Site prevailed conditions which might be followed by any of the
Engineer Site Instruction.
8. If the Sr. CM or the CM received any Comments on the replied Shop drawing, RFI,
Material submittal which shall consist any variance other than the original Design
Drawing, BOQ, & the specs. The comments shall be verified with the engineering
team. Then A proper notification of variation to be issued to the engineer as per
contract procedure.
9. Monitoring & Updating the Cash Flow on regular basis based on the actual running
cost, overheads & awarded packages meanwhile Identifying ay upcoming risk to
mitigate it at early stage.
10. The Study of the BOQ Items on a lump sum contract at the initial stage would get
some positive commercial proposals for some materials changes which could save
time & cost, one of the sample which i have faced was proposing a replacement of the
screed layer under a Carpet Bedding “on the hotel building” to a Terrazzo Tiles, for
which the terrazzo actual cost was less than the screed actual cost, while the screed
BOQ rate was less than its actual cost. The proposal was made on site based on the
accuracy of the tiling workmanship rather than the screed workmanship in addition to
the tidiness of the executed work.
Engineering, Materials& Procurement: In general, Most of the High-rise buildings critical
paths’ follow the same criteria “except for any special inclined or cantilever structure or any
contract imposed additional Milestones” as follow from end to start: Power On - Testing &
commissioning- Façade Work - Skeleton Work - Materials - Engineering works.
1. Engineering: The Engineering Lead Engine on any project should be the site team. The
Sr. CM or CM should develop internal Engineering Schedule for the Whole Project Main
& Sub activities at early stage, which allow them to have The Engineering team pushed
up ahead of schedule for all anticipated required coordination drawing for any of the
upcoming activities such as below:
* Façade Work: Installation Shop drawing of the façade has to be developed in
coordination with Façade Lighting as a prerequisite, Location of BMU Cradles
4 | Page: Introduction to My Self - Work Experience & Knowledge - By: Anas Assasah
restraint points to be coordinated as well on the fabrication drawing if its required by
the designer, any civil works or structure might be required for the
Stick/Curtain/Window system to be coordinated on drawing at early stage in order to
be executed with the skeleton phase. As to be ready for installation once the
materials are on site.
* Raft Work: MEP sum pits locations, Lifts or Escalators Pits Supplier depth & size
requirements, shop drawing for any embedded first fix work, Earthing & Lighting
materials, Waterproofing approvals & shop drawing; all to be produced & ready once
the project has commenced “if the enabling package already executed”. To avoid
any anticipated delay on the raft work.
* All Roof Works: All coordination drawing from all concerned parties of the roof floor
has to be ready ahead as this is the last critical activity in order for the tower to be
ready to receive any roof fixed long lead items / MEP Materials & to complete
the façade works closure to start the testing & commissioning as explained above.
* ID Drawings; specially the hotel rooms elevations, to be coordinated at early stage
with all parties in order to have it ready on site prior to start the MEP 1st Fix work.
2. Materials:
* Materials log: as of planned order date for all In-House or small subcontracting
Manpower works to be prepared at early stage to ensure that the timing for
the LPO full cycle being taken & the materials delivered on site prior the
commencement of the activities, such as but not limited to, Plaster & Block works
materials & accessories, Tiles accessories, Cork, Insulation, Extruded sheets if
needed on any locations. Any metal packages which might be executed in house by
“Target” Team.
* Packaging strategy to be defined by the Sr. CM & the PM for whole projects, in
coordination with the procurement department. Any packaging strategy for main
subcontractor such as the ID for example if existed to be discussed & approved by
the Main contractor through a deep review by the Sr. CM & PM.
* Micro Materials schedule log for the permanent works, including Packages
Preparation Planned dates, Work Order & Contract or LPO’s planned dates, Material
submittal & pre-qualification planned dates, Delivery planned date. All to be followed
carefully by the Sr. CM or CM in due date.
* Subcontractors Related materials approvals & delivery log; such as MEP long lead
Items, Façade Works, all other main packaged related materials.
3. Procurement:
* Scope & Responsibility Matrix: Scope for the project related procurement packages
to be reviewed by the Sr. CM, Technical head prior to be floated on the market, as
well as the responsibility matrix. Contracts conditions to be reviewed by the PM, Sr.
CM to include or highlight any might needed additional clause.
Logistic Part: Proper Preparing for the site logistic Plan, Requirement, Equipment’s
considering multiple factors would save much time related to the construction work as follow:
* Tower Cranes: Type, Capacity, quantities & location of the tower crane must be studied
well at the initial stage considering any major lifts expected at the top of roof or
mechanical floor for the high-rise building to be taken into consideration for the capacity
of chosen cranes. & considering the methodology of fixation & dismantling the cranes as
well.
5 | Page: Introduction to My Self - Work Experience & Knowledge - By: Anas Assasah
* Hoists locations & size: locations to be determined & studied in coordination with the
interior & external work. Size to be determined taking into consideration the materials
sizes which the lift will be utilize to it such Curtain Walls panels for the high-rise building
can impact the size of the hoist if the monorail system to be used.
* Other welfare utilities on the High-rise towers to be planned at early stage such as labor
toilets, rest area location within the high-rise building.
* Mobilization Plan to be ready in coordinated with the client & engineer contract
requirements for offices, & other facilities.
* Shuttering System Study & Plan: Available company inhouse materials Versus the
actual site requirement through the time line of the project should be prepared to cover
the whole project structural work, including any might needed special systems;
(Jumping, Incliend, Cantileavers Elements).
Work Strategy for One Proposed Mid height Tower (45-55) Floors: The below proposal is
indicative & will vary according to the tower Floors Geometry & Areas.
Skeleton Part:
1. Two Nos of Project Engineers(One for Slab & One for the Core wall) in addition to two
Nos of Senior site engineers ( One of them would be on Night shift, the other would be
on the slab working along with the dedicated project engineer as the slab coordination
work would have much more coordination on the day shift) .The Dedicated project
engineer for the core wall to arrange for the steel, shutter, jumping of the system in
addition to any internal placing boom with tower cranes Jacking Up coordination.
2. Steel Fabrication Control if any or total Cut & Bends orders would be the CM in addition
to the both project engineers’ responsibility, as to control the whole production &
wastage cycle.
3. Usually for the typical floors, it should take the skeleton team two subsequent floors as
to achieve the peak of the learning curve in order to attain the target cycle.
Meanwhile MEP contractor for the 6 days cycle have to be working on Night shift as well.
4. Monitoring Manpower Distribution-Production Matrix should be updated on daily basis
for the first two typical slabs in order to check if any of the distributed manpower is either
more or less for any of the assigned activity & later on will be the update will be on
weekly basis to reshuffle them on a proper & productive manner.
5. The same team would be responsible for all floor clearances for the MEP-Finishing team
in addition to any structural repairing works, Any Transfer structure special
arrangements, late Coupling beams casting, switching off of the dewatering system
including any required injection works, & All logistic needed works inside the tower such
as temporary bathrooms-temporary water connections-arrangement of proper rest
areas-temporary lighting provisions.
6. The allocated team could be squeezed if the tower floor area is slight small.
In General, the skeleton works progress will be on the track by hook or crook. The
Most criticality of the high-rise is how to Assure a proper Open Work Front for all subsequent
Finishing & MEP activities in addition to the coordination role in between both & the closure of
the work.
6 | Page: Introduction to My Self - Work Experience & Knowledge - By: Anas Assasah
Finishing Work: Podium & Tower:
1. One site engineer or Finishing General Foreman (at the initial stage) would be enough to
start (Boost) up the Finishing on the parking & the back of house for any cleared shutter
floor, as the initial activity would be the parking ceiling surface preparation & painting
works to mobilize the MEP high level works.
2. For the typical Floors, I would recommend that the Core wall project engineer be
engaged for the initiation of the finishing activities on typical floors (Block or G.B
Partitioning works) along with another site engineer. As the core wall would be much
more typical when the skeleton on its way up.
3. The assigning of Projects Engineers Number, & duties depending on the finishing scale
of the Project, whether its Core & Shell Commercial, Hotel or Residential.
4. For the Hotel Project; The scope & packaging strategy would play a role of how many
people should be assigned from the main contractor to handle those packages; usually if
there is a major ID subcontractor, a different management strategy would be adopted by
assigning different zones dedicated project engineers following the Main ID
subcontractor work from coordination, or dividing the tower & the podium area into
different Zones depending on the Area Of Use, such as Public Areas “Meeting Rooms,
Ball Room, Swimming Pool, Library”, Serviced apartments, Standard rooms, Sweets &
others.
5. The same Manpower allocation Sheet (by Activity & Nos of allocated Manpower) would
be generalized for all “Target” Internal finishing manpower’s such as masons & other
logistic team in order to monitor the productivity & reshuffle them as per updated site
requirement.
6. Once the finishing is on the 40 % progress wise & the skeleton works about to finish, the
tower could be divided into three zones or more in order to concentrate on the finishing
closure activities by the assigned zones’ engineers. In addition to assigned packages
engineers.
7. A detail progress monitoring sheets for each finishing Item will be activated to monitor &
assure that the target progress % are met on weekly basis & highlight any upcoming risk
from any concerned party.
8. Weekly Civil - MEP Site Coordination Meeting among all parties shall be attended to
follow up the site issues.
9. Proper Civil - MEP Clearance format will be generated internally between the Main
Contractor & the MEP subcontractor to control the related connected activities which
required the clearance.
10. The Plant Rooms-Roof Works-Lifts Shafts Clearances Micro construction schedule will
be generated in order to be ready once the MEP Materials/Long Lead Items are on site.
11. MEP Shafts clearance program to be generated & divided 10 floors by 10 floors or less
(Depends on any special materials or expansion joints location) to facilitate the shafts
closure.
12. The Projects engineers should be encouraged to be involved on the technical
coordination for both the structural & the Architectural works.
13. On the third & end quarter of the project. A Daily War Room meeting should be held
between all projects parties (Consultant/PMC/Main Contractor/Main Subcontractor) to
tackle any urgent site holding issues weather RFI or Required Site Instruction or Major
Inspection.
14. External works (manholes & screed, waterproofing, finishing works) will start partially as
the finishing is heading toward the end inside the tower.
15. If the Area of the tower is significant; One Project Engineer with site engineer will be
dedicated to handle the façade package.

Façade Package: My Proposed Plan for the execution of one (70) floor tower façade work
including methodologies, engineering, & executions notes.
Note: The following are based the assumption of having a unitized system mixed with
Sunscreens, Balustrade, & Louvers works. The work methodology will consider a straight
elevation with some different work at different zone such as top of tower, Mechanical floors.
* Logistic & Fixation Methodology Notes: My fixation methodology will be based on
Monorail System, bearing on mind to highlight that for some mid-size towers, &
Horizontal Buildings, some companies start using Mast Climber platforms for the
installation purposes. & this could be an option according to the tower height &
geometry.
1. Let me start illustrating the fixation methodology from the logistic side, through that will
highlight some needed information at early stage to adjust the project logistic plan
accordingly including the Material Hoist size.
2. I’ll be dividing the tower into several working zones as follows, this methodology is an
approximate & varies from tower to tower as per height, other mechanical floors louvers
areas, & top of roof special works, Decks, Cantilevers.

3. Unitized Panels sizes varies with an average of 2000 W * 3500 H, some panels would
have more width & height specially on the lower & upper levels. The average weight
varies from 250 to 350 KG. or even 500 kg for special panels
4. Panels being transferred to site packed on storage racks; the storage racks can contain
up to 4 panels. Th average weight of the of the racks varies from 1000 kg to 2400 kg
according to the panel sizes. (All is an approximate figures).
8 | Page: Introduction to My Self - Work Experience & Knowledge - By: Anas Assasah
5. In order to facilitate the vertical lifting of Storage racks to the storage floor for each zone.
It’s better to use the material hoist at Night shift. The Materials Hoist size to be taken into
consideration to allow the Storage Pallet to go inside. Usually the desired size would be
(4.00 D * 1.5 W). This has to be confirmed at early stage during the mobilization set up.
This will save Cranage time.
6. Average timing for pallets distribution per floor would be 3 to 4 hours. Most of the
materials shifting will be at night shift. Trolleys to be used to distribute the pallets inside
the storage floor.
7. Suitable Platform to be provided as well; approximate of 1 per zone to allow shifting
materials if the tower crane was used.
8. Permanent BMU system will be after dismantling the cranes to fix the balance Lift out
Glass at Cranes Tie Ins - Hoist entrance, Cleaning for the system, Final water testing.
Minor defects rectifications.
* Engineering, Initial required tests: (All the listed below points might vary from one project
to another according to the specs & requirements):
1. System Concrete embedment’s (Halfen Channels): Coordinated Builder works drawing
for the locations of halfen channels to be issued at early stage.
2. Structural Calculation report for the complete façade system to be submitted by the
subcontractors. Taken into consideration the wind load study provided by the designer.
3. Materials, Shop drawings, method statements, Production, Delivery, & Fixation
programs to be submitted at early stage.
4. Mock Up to be executed standalone (if the tower still down) to take approvals prior to
mass fabrication specially for the glass as the client/Engineer always has an issue with
the glass color.
5. Third Party Tests to be held “If the specs included” outside the project; usually done on a
close chamber to test the following “There might be more tests to be included as per the
industry requirement”:
* Air Infiltration.
* Water Penetration (Static & Dynamic).
* Wind Resistance.
* Seismic Test.
* BMU restrain test.
* Thermal cycling test.
* Condensation Test.
6. Early floating for the façade lighting package in order to coordinate it on the curtain wall
shop drawing. If applicable. BMU Related restrain load information might be required to
design the cradles locking restraint accordingly.
7. Production schedule to be reviewed at the initial stage, & followed up by factory visits to
insure the production rate is up to the agreed schedule.
9 | Page: Introduction to My Self - Work Experience & Knowledge - By: Anas Assasah
* Installation Process Notes:
1. The survey Part of the façade work is vital issue; for that the Surveying responsibility has
to be clear for both parties.
2. Signed checklist for the halfen channels locations to be issued by the Subcontractor
prior to any slab pouring.
3. Release & Handover Procedures’ forms should be used between the Main &
Subcontractors for each cleared floor.
4. Once the floor was handed over to the subcontractor. The subcontractor has to do
dimensional surveying for his work related structural element, & notify the main
contractor if anything were found out of tolerance accordingly.
5. Subcontractor Survey team will start marking each brackets position to be ready for
fixations. ONE KEY BRACKET would be marked at each sector to be used as a
reference to level & install the balance related elevations’ bracket.
6. Once the brackets have been installed; the panels to be fixed on place by the Using the
monorail & Lifting frame on a series way.
7. Alignment & leveling of fixed panels.
8. Horizontal, Vertical Joint Gasket fixations.
9. Fire barrier, Sheet, Other accessories as per specs & drawing fixations.
10. All External Balustrade, Sunscreens, & Aluminum cladding “if applicable” to be fixed by
cradles.
11. Water Hose test as per specs & requirement.
12. Water Hydrostatic Test Might be required at some areas.
13. Final Cleaning: This Items usually impose additional cost on the main contractor if the
project has been delayed, as most of the Subcontractors Agreements includes “one”
time cleaning for the façade work; which might be extended to one more time at the cost
of the main contractor.
14. QAQC procedures to be followed as per Project requirement.
* Assigned Team:
* The QAQC project assigned team to handle the façade work from the inspection
side along with below mentioned dedicated site engineer. This to be arranged
with the QAQC manager & PM weather to assign someone separately or any of
the available team. All depends on the tower size.
* The Tower to have one Sr. Site Engineer with past experience if applicable to
follow up & coordinate the façade work between the subcontractor & the projects
entire parties.
