AREA 2 DEMOLITION

Question: Page 5 of the Technical Specifications states the following:

“Project includes restoration of the area affected by the demolition works by furnishing gravel sub-base, 20 cm of top soil and grass seeding. The area shall be leveled to the maximum extent possible following the existing storm water discharge distribution points.”

These activities are not mentioned in the detailed description of works neither in Paragraph 4.A (New Works) nor in Paragraph 4.D (Demo Works). BTW, paragraphs 4.B and 4.C are missing.

Can you please confirm if these works are required and specify if they must be included in CLIN 0001 (Part A) or 0002 (Part B) of Section B of the solicitation?

Answer:

As AF standard, New works are “A”, demo works are “D”. B and C are not applicable for the project.

Question: Utilities are supposed to remain, what about shallow man-holes?

Answer:

Technical Specifications Rev. 7 Section 4 D. states:

“After completion of work the site areas shall consist solely of bare terrain - free of any sidewalks, pads or pavements. Underground utilities and manholes/pits serving the facilities will be abandoned in place. Project includes restoration of the area affected by the demolition works by furnishing inert material sub-base, 20 cm of top soil and grass seeding. The area shall be leveled to the maximum extent possible following the existing storm water discharge distribution points”.

Question: Page 5 of the technical specifications states:

“Project includes restoration of the area affected by the demolition works by furnishing gravel sub-base, 20 cm of top soil and grass seeding. The area shall be leveled to the maximum extent possible following the existing storm water discharge distribution points.”

According to HN regulations, a certain part of the demolition materials can be used as sub-base.

After a very preliminary estimate, using all demolition materials as sub-grade will turn into an average subgrade thickness of 70/80cm spread all over the entire Area 2. Is this change of the final elevation of the area acceptable or is it mandatory to dispose off-site of a certain amount of such materials? Please consider that a topographic survey is not available with elevations and details.

As specified in Technical Specifications Rev. 7: Backfilling of excavated area to restore ground to zero elevation. Contractor is permitted to use compacted crushed natural inert material (bricks, concrete, etc) as sub-base for back-filling up to a depth of -50.0cm from ground zero elevation.

From a depth of -50.0cm to a depth of -20.0cm Contractor shall use natural washed gravel compacted at 95% of max density AASHO modified test. From a depth of -20.0cm to ground zero elevation Contractor shall use 20.0 cm of top soil and grass seeding.

Contractor may re-use material up to -50.0cm from the existing ground zero elevation that will have to be maintained. All exceeding material will have to be transported off base.
