SQL Server Group BY weekly clause blank if no data - sql

Question

No. 1 Query group by weekly
SELECT
DATEADD(week, DATEDIFF(week, 0, DailyDate), 0) AS WeekStart,
SUM(Soil) AS TotalSoil,
SUM(Rock) AS TotalRock,
SUM(Concrete) AS TotalConcrete,
SUM(Steel) AS TotalSteel,
SUM(MovementPiles) AS TotalMovementPiles,
SUM(Total) AS OverallTotal
FROM
BplPjtRevenueStreams
WHERE
DailyDate > '2016-11-28 00:00:00.000'
AND DailyDate < '2016-12-05 00:00:00.000'
AND Project_Id = 5
GROUP BY
DATEADD(week, DATEDIFF(week, 0, DailyDate), 0)
No. 2 query which have empty data in the table since table has no project_Id = 6 yet
SELECT
DATEADD(week, DATEDIFF(week, 0, DailyDate), 0) AS WeekStart,
SUM(Soil) AS TotalSoil,
SUM(Rock) AS TotalRock,
SUM(Concrete) AS TotalConcrete,
SUM(Steel) AS TotalSteel,
SUM(MovementPiles) AS TotalMovementPiles,
SUM(Total) AS OverallTotal
FROM
BplPjtRevenueStreams
WHERE
DailyDate > '2016-11-28 00:00:00.000'
AND DailyDate < '2016-12-05 00:00:00.000'
AND Project_Id = 6
GROUP BY
DATEADD(week, DATEDIFF(week, 0, DailyDate), 0)
May I know if I want to do something like this for the No. 2 query?
Week Start TotalSoil TotalRock TotalConcrete TotalSteel TotalMovementPiles OverallTotal
1 2016-11-28 00:00:00.000 NULL NULL NULL NULL NULL NULL
1 2016-12-05 00:00:00.000 NULL NULL NULL NULL NULL NULL
Is it possible to do like this if it's empty result in the table?
