Starting projects always not an easy things. Furthermore when we are on joint venture which this is first time we are going to implement consolidate joint execution of project. Our first joint venture was being handover to one partner to execute.
First joint venture agreement which need to agree and give to client. Next was agreement how to separate the builders work. Which partner want to do this and that and equivalent to partner equity. This matter i found was very tiring exercise which finally took almost two months to resolve!!!
Next was finding contractor and consultant site office. It made worst when we had no area to construct site office and to settle with rental building along 2 kilometer of our site. And consultant show their 'lancy' not to accept our proposal.
After settle with location, now to arrange renovations, table, chairs and others equipments to made our site office a better place to work.

During my study at UKM, our practical to be done during third year second semester. Each students will be sent to engineering company selected by university. During my time, two students for each company. Most of companies are civil engineering consultant.
We stay at ukm medical campus at kampung baru dan had to take bus every day to subang jaya. We had to go out as early after suboh prayers to catch bus. Coming back from was more difficult as Subang jaya at that time was very difficult and remote place not like today. If we miss bus, we had to wait for longer time. Later I bring back my motorcycle to commute from kl to subang. Later I move to shah alam rent room with my office mate.
Last two months of training we was send to site office. There was few engineers and supervisor which one of them I meet later when I start work at ipoh plus highway.
We learn so many things at site and one incident involving using mackintosh probe which I remember until today.
Mr resident engineer want us to carry out probe at filling area which we not aware that how hard was the compaction was. Normally mac probe was done at new or undisturbed area. After few hours hammering the probe, we cannot pull out the rod and had to call backhoe to help.
Actually what they done at Sime Uep was a controlled filling which newly implemented in the country. This technique will allow immediate construction of house upon filling earth completed. Filling needed to filled at controlled thickness and testing will be carried out each layer.

After almost than six month prepare, submit and lobby two most prestigious elevated bridge, we finally secure one package at ampang site.
From five tender submitted, three been shortlisted which one was the lowest amount among tenderes and the other two being selected due to technical proposal.
Now enter another interesting phase where we are working how to run and manage project as joint venture at 70:30 share portion.
This is the first time I will involved from start to form jv at site and manage together.
Previously my involvement was either the majority control everything or under minority which been given less portion.
Next month will be very interesting and tricky situation.
Even now I already feeling the heat.

This is another my favourite photo.
First excavation without proper shoring and safety marker.
Make the matter worst, the sand was sandy type. Difficult to handle, easier to collapse and danger to workers inside the pit.
secondly why excavation been done near road/
Actually this excavation been done to locate the actual damage of sewerage pipe after testing failed. During excavation, we found that sewer pipe is broken and need to be replaced.
Difficult to establish why it broken. maybe because its alignment was swing towards road area and affected by compaction during road construction.

Roof leaking or damage can happened when we just complete a buildings.
It might happened few days after its had been installed or after sometime or after it experiance heavy rain and wind.
For above case, damage happened after all services been installed.
The frame for ceiling was not good enough to hold anythings attached to it. It might be ceiling itself or lamps or any ducting fix to frame or any water pipe running just above it.
Poor M &E and C&S consultant and architect didint coordinate properly to check weight or anythings attached to ceiling.
Thre are cases ceiling board didint clip to frame and it will blown away after heavy rain with strong wind.

This photo show how poor our supervision team. Again it was workers that decide the outcome of product and this is what happened. What made me mad with my supervisor was he still accept this shoddy work and still think it was right to do so. The socket arrangement show that they not event border to use any tools to make the arrangement of socket nice and neat.

Cutting of earth or hills are one of important element in construction of highway or in above photo, railway track.
Earth or suitable material use to fill at excavated area which above ground water level and building of embankment.
Proper filling of earth or suitable materials called controlled filling which mean thickness of fill specified and compaction to be done using certain weight of machine such as roller with vibration. Density test to be carried out every thickness of filling. Normally filling height recomended are 300mm and roller must be with vibration.
Cutting of hills will involved cut of top soil, earth or rock.
As i involved in photo above, top soil are more than 100mm thick. when we carried out test for earth materials, it didnt pass to be suitable material for filling and we had to dump somewhere and it was costly for contractors as rate are normally very low.
For rock or hard materials, we had to arrange rock blaster to remove it for embankment. Process fro blasting more tedious since it involve dynamite which are controlled item which we need special permit to get it. Blater also must be a qualified with authorities.
And lastly dont forget to carry out surface drain silmutanously when cutting operation been carried out.

Today i saw this old photo during my involvement in maintaining of roads and it was the first time i was on the newspaper.
The existing old bridge was partly damage during flood and been consider no longer safe to use by public. With the initiative of state head of public works dept, we bring state works exco to visit site which we are constructing new approach for Bailey bridge and hope to get assistance for funding for permanent bridge in future. At that time we almost finish removal of unsuitable material and doing sand replacement.
Few weeks later the temporary Baily bridge was completed and been open to use until permanent bridge available.
To my surprised today five years later , there are no news regarding the permanent bridge and nobody have any idea when it will be constructed and that temporary still serving the traffic. Looks like it will be there for long time.
What a shame !!!!

The differential settlement at some spot of this highway getting very bad as our Jazz car hit the gound many times when i didnt slow down. It was bad riding surface at certain area compare to other toll highway in the country. Few years ago i saw major repair near bridge area but looks like it was a continous problems for them.
For me, its too late to repair until satisfactory. They can only minimize settlemet by overlaying or topping premix regulary.
Only contractor and consultant know what happened during design and construction.
Few question always come to my mind when i travel using this highway.
1. What kind of design for ground treatment been used in this marine clay area.
2. Did geotechnical designer have enough site experiance when they proposed the design?
Of course they have licenced to design as permit by laws but results not encouraging so far
3. Did contractor follow recomendation made by geotechnical designer? or bulldozing all the way
4. Did contractor have good site engineer with geotechnical knowledge?
5. Did the settlement monitoring being done accurately?
Finaly did highway open in rush due to financial reason? based on my experiance, i dont think so.
Meanwhile, user had to swallow when using this highway and becarefull at few location.
