Tips on using this forum..

(1) Explain your problem, don't simply post "This isn't working". What were you doing when you faced the problem? What have you tried to resolve - did you look for a solution using "Search" ? Has it happened just once or several times?

(2) It's also good to get feedback when a solution is found, return to the original post to explain how it was resolved so that more people can also use the results.

Dear Michael,

Residential compounds (villas construction) normally are divided into three major elements in construction phase.

1) Villas
2) Infra Works
3) and Common Facilities / Recreational Buildings

Most Contractors finished first the infrastructure works (underground utilities, road works, etc), then construct the villas and common facilities. You can group typical Villas into one sub-element in the schedule.

Possible work packages are:
Infra Works
- Site preparation
- MEP works
- Road works and hardscaping
- Landscaping
- Boundary wall

Villas & Common Facilities
- Structural works
- Blockworks and plastering
- Metal works
- Kitchen cabinets and wardrobes
- Waterproofing works
- Doors & windows
- Tiling works
- Drywall partitioning & painting works
- Suspended ceilings, if in Contract
- Mirrors
- Equipment
- MEP works

You have to get Client’s approval of the schedule and let him/her lead in having it followed by all stakeholders.

Look for clauses in the Contract that requires them to follow the program of works.

Hope from above details you can have an idea in sequencing your works.

Best regards,
R. Catalan

Hi Trevor,

There should be a plan for sure. You should ask the sequence to whom gonna build it. Subcontractor, site engineer, foreman etc. You have cards in your hands also. Tell them if they cannot give you a sequence and time, or will not continue through your path then the procurement of the main materials as concrete reinforcement, wet surfaces, etc. will be late to perform the job. And if it is a subcontractor, you can threat him with penalties or early contract termination due to end of continuity of the work.

From technical aspect of view, your CLIENT need to accept the duration and link changes on your active schedule. This may lead to a change in critical path and some variances which differs in scheduling programs and cost rules. Planner must be carefull when dealing with these.

Best Regards,

Safak

Hi Trevor

At least there will be some pretty wall paper for the site hut.

Best regards

As long as your crew has no intention to follow the plan, or lacks the capacity to read and understand it, you are being paid to do a job which is irrelevant. Well done?

Dear Michael,

In addition to Mike’s comment, can you please google the "Line of Balance" technique in planning. I believe that it is used for repetitive projects like your case.

With kind regards,

Samer

Hi Michael

Set up a single bottom up programme for each villa type - this is level 4

Summarise each villa type - this is level 3.

Copy the summary for each of the villas - This is level 2

Create logic links between each villa to represent whatever is the driving logic - for instance:

1. Resource availabilty
2. Plot release schedule
3. Cash flow - sales
4. Anything else

Then summarise the villas into the whole project - this is level 1.

You will now have a logic linked programme that is easliy adjusted if the level 2 programme sequence has to be changed.

Best regards

Mike Testro
