Situated on the Eastern bor-der of home is the Kingdom of Cambodia, with its capital city Phnom Penh:

During the last decade Cam-bodia recovered from its political turmoil and attained a stable economy in the process. The new era came with its share of infrastruc-

tural development and em-ployment opportunities, es-pecially in Phnom Penh.

As part of this development, PBL Group had taken up the role of Post Tensioning de-sign and supply to Cambo-dia. Since the year 2000, PBL has been proud to be a part of this development of a modern construction sector in its neighboring nation.

Some of the few projects for which PT design has been undertaken by PBL are as follows:

Message from the Editor again to take a lead in PT design supply.

All said and done, we have come to the end of another year. I personally remember starting off with the first edi-tion of this Newsletter, and now, we turn another new leaf into the year 2008 .

We welcome your comments and contributions. Kindly contact us at the addresses listed on the last page.

On behalf of PBL Group and its partners, I wish all our readers a successful and prosperous year ahead.

Editor

Dear Readers,

The year has come to an end. So fast! It feels like it was just yesterday I edited the very first edition of this Newsletter. We have defi-nitely come a long way, suc-cessfully.

In this concluding edition for the Year 2007, I am person-ally proud to present for the first time, PBL’s contribution to Kampuchea, a Kingdom dominated by the Mekong River and home to on of the world’s greatest achieve-ments: Angkor Wat.

Catching up with the pace of national development, both

national and international investors are flocking into this serene kingdom, and PBL Group is proud to be amongst the pioneers.

Heading f rom r i ver s guarded by the dragon and the swan, PBL also heads to mark its presence in Saigon. A brief of some of the pro-jects, in which PBL Post Ten-sioning Systems have been used, since the year 2000 is presented herein.

Also in this issue, we once again trot into the Gulf to get a peek at what out part-ners have been up to in the current year. Al Sahel is the name that surfaced yet

Inside this issue:

Phnom Penh’s theatre com-plex. The entire redevelop-ment including the addition of an annex serving as a Function Hall for social events and public gather-ings.

A total area of 2000 square meters comprising of PBL SF 405 post tensioning systems, was used in the entire project.

The Golden Mall Following the success story of Soraya, The Golden Mall, a 5-storey structure, once completed would serve as

another landmark shopping Center in the heart of Phnom Penh.

The architectural function was designed by A-Seven Corporation in Thailand while the structure and post-tensioning system was de-signed by PBL Group. The

developer and contractor was Canadia Bank. The building was expected to serve customers around at

...Neighboring nation.

tion Rooms, Restaurants, Health Club and Fitness Cen-ter, Typical Office Spaces, Typical Service Apartments, Penthouse and a Helipad at the Roof Top.

Upon completion, the tower would stand as the tallest building in Phnom Penh at a total height of 118.40 m above ground level. It also goes three levels into the basement, to a depth of 9.80 m below Ground Level.

The OCIC Tower located in Phnom Penh would be re-corded in history as the be-ginning of a new era in high rise buildings in Cambodia. This is the pioneering high-rise following the nation’s economic recovery after resolution of political and civil conflicts.

The Tower is mainly in-tended to serve as Canadia Bank’s Head Office. Out of the 3 Basement, 5 podium and 24 levels, covering a floor area of 45,000 square meters, majority would be designated for Bank Of-fices, Stock Exchange, Func-

Worthy of note, is the strength of the mat founda-tion on which the entire tower places its loads. The mat spreads over the 145 ∅ 800 mm bored piles.

Due to constraints of a lim-ited foundation thickness and excavation, post tensioning was proposed for the mat foundation. As a result, shear strength was enhanced and the foundation’ thickness was maintained as required.

Similarly, the Tower’s struc-tural system comprised of post-tensioning slab frame. The shear wall acting as the core, along with the perime-ter frame functioned to resist lateral loads such as wind and earthquakes.

Given the essence of the perimeter frame, PT band beams were used to in-crease total stiffness supple-menting the tower’ core.

If one single tower could be as amazing as the OCIC Tower, then, certainly, 7 similar towers all in a row, be a thing of beauty lining the horizons of Phnom Penh.

Rightfully christened as the Rose Condominiums, on 16,632 square meters of land area, the Towers would be constructed in 3 phases:

Phase 1 17,950 square meters Tower A (25 stories) with 71 Units of residential units.

Phase 2 37,935 square meters Tower B (31 stories) with 94 Units of residential units.

Tower C (25 stories) with 71 Units of residential units.

Phase 3 77,920 square meters Tower D (25 stories) with 71 Units of residential units.

Tower E (31 stories) with 94 Units of residential units.

Tower F (31 stories) with 71 Units of residential units.

The condominiums are well facilitated with a Club House, Swimming Pool, Car park and other facilities..

The Rose Condos is also owned by the Canadia Bank and the architectural designs done by A7 Corporation in Thailand.

Not only is the Rose expected to serve the executive and elite, it is expected to provide housing for the influx of for-eign investors and citizens, who are now moving in to the rising city of Phnom Penh.

As Phnom Penh marks its horizons with Towers, the adjacent Island City also lines up in order to meet with the demands of infra-structural demands to serve the growing needs of the Kingdom of Cambodia.

The Mekong River, flowing through Phnom Penh cuts this portion of land and sepa-rates it from the main land, and thereafter referred to as the Island City.

Canadia Bank, which ob-tained concession from the Cambodian Government for land development on this particular island, has a vi-sion of a brand new town with commercial and resi-dential complexes, taking advantage of the beauty of nature. In addition its close proximity to the Ministerial

offices in Phnom Penh gives the Island added value.

As always, to facilitate com-munication and transporta-tion between the island and mainland, bridges become a necessity.

Thai Architects at A7 Corpo-ration proposes spectacular and wide spans of bridge lengths over the Mekong River. With all its glory re-sembling the pages of a Fairy Tale book, A7 Corpo-ration achieved a profes-sional dream.

Bridges at two locations have been initiated with a design concept to portray Cambodian architecture and also reflected on modern design and technology.

The Swan, is designed as a cable-stay bridge resting on

one main pylon which tilts back, thus forming a ‘head’ looking out to the sun. The spans on either side, from abutment to pylon are 60 m main span and 20 m back span.

The Dragon, on the other hand is an arch bridge with 80 m span.

Each bridge has four traffic lanes, two each way, in-bound and outbound from the island. Both also have side walks.

Structural, both are de-signed box viaducts with cantilevered ribbed beams on either side. The main bridge decks designed with longitudinal and transverse post tensioning would utilize PBL’s multi-strand system.

All post tensioning structural elements, including the stayed cables are designed and supplied by PBL Group.

As the structure stands firm and domineering in a land where the Khmers believe in the luck of the dragon and the swan, the bridges will definitely stand to be more than a just a river crossing.

Dubai Silicon Oasis The Dubai Silicon Oasis has been a challenge in design and installation as its slabs are circular in shape with several openings and long cantilevers.

Al Sahel was introduced in the very first issue of the PBL Newsletter as a leading partner of PBL Group. As at today, the Post Tensioning team of Al Sahel Contract-ing Co. LLC succeeded in procuring 5 exclusive pro-jects by mid-2007. A total of approximately 1100 tons of post tensioning strands has been estimated for these.

Selected projects shall be highlighted herein, with em-phasis on characteristic fea-tures and uniqueness.

Royal Oceanic Tower

At the Royal Oceanic, the slabs are connected to a series of stiff shear walls in order to resist earthquake and wind loads. These walls however poses challenges on constructability as it obstructs stressing of the slab

Thus, a great deal of atten-tion is paid to assuring the transformation of PT forces to the slabs so as to fulfill the required crack control and strength requirements.

Regardless, the challenges of both design and installa-tion has definitely paid off as the Post Tensioning Unit of Al Sahel expands step by step and is currently being considered by main con-tracting companies as a competent and reliable con-tractor for Post Tensioning works.
