With reference to the tender of “South Commuter Railway Project / Package No. CP S- 03a & CP S-03c” we are very much interested in to attend the abovementioned tenders. And therefore we are giving out utmost effort to prepare our best and competitive price proposal with the best technical competence, our most experienced teams are working non-stop basis not only within our headquarters but also from our overseas branches and sites in order to fulfill the client requirements with a solid submission dossier. We are also try to apply for the Visas in order to come to Philippines to make latest market research, to make site visit, to introduce ourselves to the local subcontractors and vendors, and lastly but most importantly to visit all the necessary local authorities to enlighten our studies on the projects’ execution. However due to the ongoing worldwide pandemic and raising numbers of the cases, both Philippines and Turkey is in a Instruction to 1 ALL Section 21 Submission and Opening of Bids lockdown at the moment, which most probably will be extended for a duration that we Bid Submission extended for 30 days. Refer to GBB No. 8 Closed Yes 8 Bidders cannot foresee at the moment. In parallel with this situation, we only can maintain our studies remotely. But not to mention that for these such projects any of the bidders shall visit the site personally and make their very final studies locally, which no foreign bidder can do at the moment. Also as per our previous experience, the visa applications for foreigners are bounded to a prerequisite as an endorsement letter from DFA, that is taking at least 2 months duration. In the light of the above-mentioned information, and considering the magnitude of the tenders/projects we kindly would like to request 10 weeks extension from the due date of the final submission for these related tenders. We kindly wish you to understand the practical issue as stated above for working out the most competitive price and hoping you will be kind enough to consider our request for this extension of time.

Request for the deadline of bid submission to be moved on 22 September 2021. This is to provide bidders with suffecient time to prepare a more comprehensive and Instruction to Bid Submission extended for 30 days. Refer to GBB No. 8 2 ALL Section 21 Submission and Opening of Bids competitive bid. Given the ECQ/MECQ extension: (i) it is more difficult to coordinate with Closed Yes 8 Bidders sonsultants and contractors; and (ii) travel restrictions for foreign partners to enter the Philippines.

We hereby request in writing an extension to the deadline of bid submission for Package 3a and 3c. Preparing a fully responsive and competitive bid requires comprehensive research on all aspects of bid requirements. Howver, COVID-19 crisis and its consequential measures to prevent further contaminations are giving us challenges in Instruction to mobilizing our key resources which, in turn, is causing delays in tender activities Bid Submission extended for 30 days. Refer to GBB No. 8 3 ALL Section 21 Submission and Opening of Bids Closed Yes 8 Bidders especially those related to iterations with suppliers and specialits. Given those circumstances, we sincerely request an extension of 60 calendar days, up to 20th August 2021 as the new deadline date for bid submission. In addition, it is believed that this extension of bid submission shall affect the deadline for bidders to submit clarification accordingly.

With regard to the subject project, we would like to bring your kind attention that we are currently under preparation of the tender proposal with keen interest to be involved in this project, However, we are facing an insufficient time to prepare a competitive and a compliant proposal to meet the requirements of bidding documents due to multiple reasons. 1) Due to the COVID-19 situation, foreigners entering Philippines are being Instruction to strictly controlled, and we are not able to execute a site survey until this moment. 2) As Bid Submission extended for 30 days.

For the foregoing reasons, we are of the opinion that additional tender preparation period is certainly necessary, and respectfully request for at least 8 (Eight) weeks extension from the current bidding date.

We are very much interested to participate in the bid of te above-mentioned projects, however our team will require more time to come up with a complete and competitive Instruction to Bid Submission extended for 30 days.
