PREFACE

Infrastructure represents “wheels” if not “engine” to economic activity. Since the major share of NTC’s revenue is associated with it, all investment decisions, allocations of funds and their efficient use – for the up gradation and expansion of infrastructure – assume great significance. Cumulative impact of deregulated telecom environment, privatization of PTCL, entrance of new market players, and government telecom policy, is a precursor of highly inadequate infrastructure on a national level. NTC’s predilection to make up for the infrastructure deficiencies is therefore a strategic compulsion.

During the previous years, NTC has given a good account of itself in pursuing infrastructure/ network expansion. Consequently – loading of Fiber Optic Cable, on main, alternate, spur – junction routes, installation and commissioning of NGN, IP core routers, Green Exchanges, GPON, data networking, execution of ‘Project Horizon’ etc have been completed. NTC is providing IT & Telecom services to the Government of Pakistan up to tehsil level.

NTC’s long haul digital media on main and alternate routes, runs parallel to PTCL, and is providing ‘stream level connectivity throughout the country. NTC has its independent network of local and transit exchanges. NTC is fully established to meet the requirement of GoP/ Defence through its network/ infrastructure.

Available capacity on the existing optical fiber backbone has been utilized to the optimum. The project is therefore directly linked with the capacity upgrade of the existing optical fiber backbone. Up-gradation of the existing countrywide SDH backbone (STM-4) to DWDM network is to meet the future bandwidth requirement of the government and semi government sector.

INFRASTRUCTURE UP-GRADATION

1.1 Existing OFS Network of NTCNTC’s Optical Fiber pair on main alternate and spur routes has been equipped with 622 Mbps SDH system (Siemens SMA1/4) on the following alignments:

1.1.1 Main Route (on eastern bank of river Indus)

Karachi – Hyderabad – Sukkur – Multan – Rawalpindi – Peshawar.

1.1.2 Alternate Route (on western bank of river Indus)

Karachi – Thatta – Dadu – Larkana – Shikarpur – D.G. Khan – Bannu - Peshawar.

1.1.3 Spur Routes

Gujranwala – Daska – Sialkot / Sargodha – Joharabad-KCP / Sargodha-Iqbal Town/Taxila – Haripur – Abbottabad / Nowshera – Mardan / Kamra – Attock / Sahiwal – Arifwala .

1.1.4 Junction Routes

Islamabad Junction network, Lahore Junction network, Karachi Junction network.

1.1.5 Both main and alternate routes start from Peshawar and end up in Karachi. Main and alternate route / cables join (on one system) at Peshawar Cantt and Pak Capital exchanges – forming three major self healing ring configuration and four sub ring configuration within above rings, thus provisioning of interruption free telecom services are ensured. Average distance between regeneration sites is 50 km. Number of ‘regeneration sites’ and ‘add/drop multiplexer sites’ are ‘40’ and ‘58’, respectively.

1.1.6 Spur routes are basically extensions of the Main and Alternate route cables. For example, Taxila to Abbottabad is a spur route covering Haripur, Havelian and Abbottabad. Taxila is a point where main route cable has been extended towards Abbottabad. SDH system at Taxila is common for main and spur route.

1.1.7 NTC has its own Optical Junction networks in three main cities of Pakistan, i.e. in Islamabad, Lahore and Karachi. These networks are in ring configuration with self healing provision, currently these are working on SDH STM-4 level in Lahore & Karachi where as in Islamabad the junction network is SDH STM-16 based.

1.1.8 In addition, Coastal communication link between Jiwani – Karachi has been recently established. This transmission link has been equipped with STM-16 (2.5 Gbit) system and will be connected with NTC SDH backbone for the provision of connectivity with dry ports, air ports and business centers of the country. This expansion will facilitate mobility / exploitation of resources and would enhance business opportunities.

2.17 EVALUATION OF BIDS

2.17.1 Technical evaluationIt will be examined in detail whether the system/works offered by the bidder complies with the technical specifications of the tender documents. For this purpose, the bidder’s data submitted with the bid will be compared with the technical features/criteria of systems/works detailed in the technical specifications

2.17.2 Commercial Evaluation: It will be examined in detail whether the bids comply with the commercial / contractual conditions of the tender documents. It is expected that no major deviation/stipulation shall be taken by the bidders.

2.18 EVALUATION CRITERIA / METHOD

2.18.1 The technical proposal & “conditions of Eligible bidders” shall be evaluated first. The bidder shall qualify for opening of financial bid only if it meets the technical specifications/requirement of NTC. Threshold marks for technical qualification shall be 75 %. Total score obtained by bidders shall be calculated in such a way that 60% weight age shall be taken from technical score and 40% weight age shall be taken from financial score and the contract will be awarded to the highest scoring bidder. The formula for calculating total score is as follows:

19

Technical Evaluation

Marks obtained x 0.6 = “X” Total marks

Financial Evaluation

Lowest value in PKR. among the offered bids (after loading , if required) ) x 0.4 = “Y” Value of bid in PKR. of respective bidder (after loading, if required)

Total Score (Z) = X+Y

Contract will be awarded to highest scoring bidder

2.18.2 Price adjustment for Commercial Compliance:2.18.2.1 The cost of making good and deficiency resulting from technical compliance will be added to the corrected total bid price for comparison purpose only. The adjustments will be applied taking the highest price quoted by the other bidders being evaluated in detail in their original bids for corresponding item. However lowest price shall be considered for the contract. In case of non-availability of price from other bidders, the price will be estimated by the tender evaluation committee.

2.18.3 No bidder shall contact NTC on any matter relating to its tender from the time of opening to the time of contract is awarded.

2.18.4 Any effort by a bidder to influence NTC in the tender evaluation, bid comparison or order award decision may result in the rejection of his bid.

CONCLUSION

9.1 Faced with the multifaceted challenges of increased service needs, explosive demand of bandwidth, fiber exhaust, and layered bandwidth management, etc - service providers have become desperate to weigh conflicting options. Enhanced bandwidth requirement has been further compounded with the integration of switching and transmission in optical communication networks. One way to alleviate fiber exhaust is to lay more fiber, and, for those networks where the cost of laying new fiber is minimal, this will prove the most economical solution. However, laying new fiber will not necessary enable the service provider to provide new services or utilize the bandwidth management capability of a unified optical layer. Beginning with DWDM system, under the cover of NTC’s infrastructure up gradation project, service provider can establish a grow-as-you-go infrastructure, which allows him to add current and next generation systems for virtually endless capacity expansion. Because a DWDM infrastructure can deliver the necessary capacity expansion, laying a foundation based on this technology is viewed as the best place to start. Making investment for the infrastructure Up-gradation, as a strategic partner, would therefore be coup de maitre.
